| Brief Description: A damage survey conducted by National Severe Storms Laboratory meteorologists confirmed F2 damage approximately 6 miles southwest of Dustin, when 80 percent of a house roof was blown off. As the tornado moved east-northeast sporadic roof damage was sustained to other homes; an antenna was wrapped around a telephone pole; trees were damaged; farm buildings were destroyed; power poles were bent, and two feeders were bent up. The tornado then tracked into McIntosh County. See storm data from the National Weather Service Office in Tulsa for more information on the McIntosh County segment of this tornado. Eye witnesses described the tornado as multiple-vortex. Severe thunderstorms affected most of central and eastern Oklahoma on the 20th. More than a dozen tornadoes were confirmed, with four occurring in the Norman Forecast Area. See Tulsa storm data for information on eastern Oklahoma tornadoes. Little damage from straight-line winds was reported, however there was a large amount of large hail. | |||||||||||

| Brief Description: A tornado first touched down near Burney, which is in western McIntosh County near mile marker 248 on Interstate 40. The tornado travelled parallel to and south of the interstate in the Tiger Mountain area but then crossed interstate 40 closest to mile marker 249 as it was lifting. Most of the damage from this tornado was F1-strength, but some F2-strength damage occurred. The tornado first destroyed two mobile homes. Roofing from the first destroyed home was found 150 feet to the east, and a car was crushed in a car port. The second mobile home destroyed was a brand new double-wide that had recently been tied down. The mobile home rolled 30 to 40 feet and was totally destroyed. Four members of a family inside the home were injured, one of them critically. Two cars in a car port were damaged. Further east, shingles were torn off the south and west sides of a house, and a tin shed was destroyed with debris scattered to the north and east. Another shed with appliances inside was destroyed. The tornado then passed near a small dwelling, where numerous large trees were down and a 20-foot pontoon was moved 15 feet over a tree. The tornado then hit another double-wide mobile home, which had its apron blown out on one side, had trim peeled off, and it had a window broken. Two nearby power poles were snapped off. Finally, the tornado passed a well-built two-story home. This home had shingles blown off the roof, windows broken, a sun porch was destroyed, a metal hay shed lost its roof, many large trees were blown down, two small storage sheds were destroyed,a 20-foot horse trailer rolled over, and a Ford F150 crew cab was moved 10 feet. Summary of events for March 8 1999: A band of moderate to heavy rain moved across the area during the morning of March 8 in association with a warm front out in advance of a low pressure center. The rain brought localized nuisance flooding. Once the morning rains passed, warmer air moved into eastern Oklahoma during the afternoon, and an upper level low with lots of cold air aloft moved into the area. Thunderstorms then erupted late in the afternoon along an eastward moving dryline/cold front. Some of these thunderstorms displayed characteristics of low-precipitation supercells which then produced damaging tornadoes, most notably in McIntosh County and at Broken Arrow in Tulsa County. The Broken Arrow tornado occurred miles behind any radar-indicated thunderstorm activity and was possibly the result of a cold-air funnel under the cold upper low which reached the ground. | |||||||||||

| Brief Description: The same parent storm which produced a tornado near Burney and Tiger Mountain produced another tornado which touched down near Pierce. At Pierce, the tornado removed roofs from quite a few homes. In Pierce, the tornado also damaged vehicles and boats. Further east, the tornado crossed Interstate 40 near Fountainhead Road (OK Hwy 150). As it crossed the interstate, four 18-wheelers were knocked over, but the drivers escaped injury. After crossing the interstate, the tornado travelled through the Sycamore Bay development, damaging ten to twelve homes. The damage included cracked ceilings, a destroyed garage, and shingles ripped off to the bare wood. One home was moved 30 feet from its foundation, and it took the roof off of another. The tornado then crossed Lake Eufaula as a waterspout, destroying five boats and several docks at Emerald Bay. Once the tornado came back onshore, it hit Lotawatah Road, where it moved a double-wide mobile home from its foundation. Another home lost its roof, and outbuildings were destroyed. A trucking company was hit, destroying five 60-foot trailers and damaging others. The tornado then crossed Humphrey Road at a racing stable, destroying six of their structures and six corrals. When the tornado reached US Hwy 266, part of a home's roof collapsed, and a horse trailer was thrown on top of a barn, which then collapsed. Along its entire path, numerous power poles were snapped off at the base. Spotters reported seeing two or three simultaneous tornadoes at times. Fortunately, the tornado lifted just before entering Checotah.

| Brief Description: EVENT NARRATIVE: A strong tornado severely damaged homes, snapped and uprooted numerous trees, and blew down power poles and power lines. EPISODE NARRATIVE: Elevated severe thunderstorms containing large hail developed north of a warm front that was moving slowly northward across eastern Oklahoma and west central Arkansas during the morning and early afternoon of the 10th. Another round of severe thunderstorms developed late in the afternoon as a dry line approached the area from the west. Extreme instability and strong vertical wind shear resulted in the development of long-lived supercell thunderstorms that moved across eastern Oklahoma and northwestern Arkansas during the late afternoon and evening. Several of these supercells became tornadic and a few produced long-lived damaging tornadoes. One such supercell developed and moved along the Oklahoma-Kansas border and then into southwestern Missouri. This storm produced a tornado in northeastern Craig County OK that remained on the ground for 29 miles in Oklahoma, continued for about 31 miles in Newton County MO, and finally dissipated about 15 miles into Barry County MO. It produced EF-4 damage in several locations, including Picher, a small town in north-central Ottawa County OK. Twenty-one fatalities, over 350 injuries, and an estimated $60 million in property damage resulted from this tornado in Oklahoma and Missouri. Six of the fatalities and about 150 injuries occurred in Picher OK. Other strong tornadoes developed and moved across portions of Pittsburg and Latimer Counties. A EF-2 tornado was on the ground for about eight miles west of McAlester, damaging numerous homes in its path. Another EF-2 tornado developed southwest of Hartshorne in Pittsburg County and moved 19 miles before dissipating just east of Yanush in Latimer County. Four injuries resulted from that tornado and numerous homes were severely damaged or destroyed. | |||||||||||

| Brief Description: The F3 tornado described here was the second of two tornadoes to touch down in the Checotah area on the evening of June 1. Both tornadoes were spawned from the same parent thunderstorm. Even though this tornado had a stronger F-rating than the first, it caused less widespread damage since it travelled through a less densely populated area. The second tornado touched down on the southeast side of Checotah near I-40 and Grapevine Road at 650 PM CDT. The tornado travelled southeast for 4.5 miles and then lifted at 706 PM CDT. Damage assessments in Checotah combined the effects of the first and second tornadoes. For details of the damage assessment, see the third paragraph of the narrative for the Tornado entry immediately preceding this entry. This tornado, the second of the two, was rated an F3 based based on the near-complete destruction of a farm house 3 to 4 miles southeast of Checotah. Summary of events for the afternoon and evening of June 1 1999: A cold front moving in from the northwest moved into an extremely unstable air mass on the afternoon of June 1. Along the front, an isolated supercell thunderstorm developed around the Pryor/Locust Grove area and then moved in a slow and unusual south-southwest direction.

| Brief Description: Surveys revealed that this tornado formed about a mile east of the intersection of State Highway 48 and county road EW129. About one mile after touching down, the Wewoka tornado apparently merged with it. This tornado damaged a house and destroyed numerous pecan trees shortly after the merger. The tornado moved east passing one-half mile south of the town of Yeager, but overturning a mobile home and downing power lines along a railroad just south of town. The tornado then began moving east-northeast as it moved south of Yeager. It completely destroyed a mobile home and toppled an oil pumping jack and storage tank east of Yeager. The last damage was a barn damaged 4 miles east of Yeager and the tornado lifted at 815 pm. The Yeager tornado was on the ground for 8 miles with a maximum width of four-tenths of a mile. This tornado was rated F2 (winds estimated between 113 and 157 mph) based on the destruction of a mobile home east of Yeager. Summary of events of June 8, 1998: Severe thunderstorms developed and moved across much of Oklahoma during the afternoon and evening of the 8th, producing hail as large as softballs, wind gusts to 70 mph, and 3 tornadoes. The tornadoes were spawned by a single storm between 6 and 715 pm CST in Pottawatomie and Seminole Counties. The first tornado (an F1) touched down 3.5 miles west-southwest of Maud in Pottawatomie County, moved east into Seminole County, lifting about 11 miles west-southwest of Wewoka. The second tornado (rated F2) touched down 2.5 miles southwest of Wewoka in Seminole County, moved east through Wewoka, and crossed into Hughes County. Meanwhile, the third tornado (also an F2) developed about 4.5 miles west-southwest of Yeager in Hughes County. These two tornadoes then merged about 3.5 miles southwest of Yeager and continued east until they lifted 4 miles east of Yeager. This tornadic thunderstorm also produced hail as large as softballs southwest of Seminole in Seminole County. Baseball sized hail was reported with a different storm in Oklahoma City in Oklahoma County. Widespread hail and wind damage occurred in Ponca City in Kay County and in Norman in Cleveland County. Wind gusts were estimated as high as 70 mph near Wellston and Warwick in Lincoln County. Significant thunderstorm wind damage occurred throughout Lincoln County, in Purcell in McClain County, and near Calumet and El Reno in Canadian County.

| Brief Description: This tornado track is the continuation of the same tornado that tracked through Okfuskee County earlier in the evening, producing F2 damage. In Okmulgee County, the tornado only produced F0 damage in the form of numerous trees downed/uprooted along its path. When all was said and done, this tornado tracked 27 miles from 2_SE Boley to 3_SW Nuyaka, and it injured four people in Okfuskee County. Summary of tornado/severe events for October 4 PM - October 5 1998: Oklahoma's worst-ever October tornado outbreak took place on the evening of October 4. At least 22 tornadoes occurred throughout Oklahoma, of which seven were in northeast Oklahoma. This outbreak of severe weather resulted as a powerful upper level storm system moved across the central plains and surface low pressure developed over southwest Oklahoma. Warm humid air quickly invaded the area on the morning of October 4 and then collided with a cold front moving southward by evening. The threat from these storms ran the full range of possibilities from destructive tornadoes to damaging winds to very large hail up to the size of baseballs. Numerous storms occurred on the evening of October 4, mainly north of Interstate 40. The two most significant storms both moved eastward out of central Oklahoma. One produced an F1 tornado that passed through Pawnee. The other produced a 27-mile track F2 tornado that started in Okfuskee County and ended in Okmulgee County. This second storm later went on to produce considerable hail and wind damage in the city of Okmulgee. Many other thunderstorms developed during the evening in central Oklahoma, fanned by upper level winds in excess of 100 knots. These storms moved into northeast Oklahoma, causing additional severe weather late in the evening that gradually spread eastward to the Arkansas state line. After midnight, the storms congealed and became a slow-moving line of thunderstorms that sat over nearly the same area of northeast Oklahoma through the overnight hours. The severe threat gradually diminished through the night, and flooding became the main problem. For more information on the flooding, see the separate event entry for the flooding. By late on the afternoon of October 5, the slow-moving line had moved into southeast Oklahoma and flared up during the heat of the afternoon, causing a few additional severe weather reports in the form of strong winds. | |||||||||||

| Brief Description: Surveys showed that at about 735 pm, a tornado touched down about 1/2 mile southwest of the intersection of US-270 and SH-59, or about 2.5 miles southwest of Wewoka. The storm moved east through the south side of Wewoka causing damage in a neighborhood in the southwest side of Wewoka and along state highway 56 in the south part of town. The tornado continued moving east destroying two mobile homes southeast of Wewoka before crossing into Hughes County. It caused minor damage to a couple of homes and unroofed a mobile home near State Highway 48. The tornado then turned northeast and apparently merged with the Yeager tornado (see separate Storm Data entry) just northeast of the intersection of State Highway 48 and county road EW129. This tornado was on the ground for 8 miles and had a maximum width of 1/3 of a mile. The tornado was rated F2 (winds estimated between 113 and 157 mph) based on damage in southwest Wewoka including a brick house unroofed and the south exterior wall blown in. Eyewitness reports indicate that this was likely a multiple vortex tornado. Summary of events of June 8, 1998: Severe thunderstorms developed and moved across much of Oklahoma during the afternoon and evening of the 8th, producing hail as large as softballs, wind gusts to 70 mph, and 3 tornadoes. The tornadoes were spawned by a single storm between 6 and 715 pm CST in Pottawatomie and Seminole Counties. The first tornado (an F1) touched down 3.5 miles west-southwest of Maud in Pottawatomie County, moved east into Seminole County, lifting about 11 miles west-southwest of Wewoka. The second tornado (rated F2) touched down 2.5 miles southwest of Wewoka in Seminole County, moved east through Wewoka, and crossed into Hughes County. Meanwhile, the third tornado (also an F2) developed about 4.5 miles west-southwest of Yeager in Hughes County. These two tornadoes then merged about 3.5 miles southwest of Yeager and continued east until they lifted 4 miles east of Yeager. This tornadic thunderstorm also produced hail as large as softballs southwest of Seminole in Seminole County. Baseball sized hail was reported with a different storm in Oklahoma City in Oklahoma County. Widespread hail and wind damage occurred in Ponca City in Kay County and in Norman in Cleveland County. Wind gusts were estimated as high as 70 mph near Wellston and Warwick in Lincoln County. Significant thunderstorm wind damage occurred throughout Lincoln County, in Purcell in McClain County, and near Calumet and El Reno in Canadian County.

| Brief Description: A significant long-track tornado occurred on the evening of October 4, following a 27-mile track from 2 miles southeast of Boley in Okfuskee County to 3 miles southwest of Nuyaka in Okmulgee County. The tornado first touched down in Okfuskee County at 1037 PM CDT and lifted over Okmulgee County at 1108 PM CDT. (This Tornado entry covers that part of the track in Okfuskee County. See the separate Tornado entry for details on the portion in Okmulgee County.) The most significant damage to structures occurred near the communities of IXL and Haydenville, while much of the damage in the rural areas across which the tornado tracked consisted of downed/uprooted trees. In the small community of IXL, located on OK Hwy 48 north of Okemah, nearly every structure sustained at least some damage. An NWS Storm Survey revealed F2 damage at IXL, where a house and two mobile homes were destroyed. Pieces of one mobile home were found one-half mile away. A local newspaper also reported four businesses and a public building at the IXL Park were destroyed. Six houses and two more mobile homes sustained major damage, while another 21 houses and one mobile home sustained minor damage. In Haydenville, located north of Okemah on OK Hwy 56, two single-family houses and a mobile home were destroyed. Three houses, three mobile homes, and one public building (the Haydenville Fire Station) sustained major damage. Five houses and one business (the Haydenville Store) sustained minor damage. An NWS Storm Survey revealed F2 damage just southwest of Haydenville, where a mobile home was completely destroyed. Four people inside the trailer were injured, one of them critically. The tie-downs on the double-wide trailer were snapped, and the home appeared to have travelled a significant distance before disintegrating. This tornado was unusual for the fact that it covered such a large area. A survey showed that the damage path was at times 3 miles wide, lending credence to the idea that there were several smaller tornadoes circulating around the larger tornado. The larger tornado reached as wide as 8/10 of a mile.

| Brief Description: An F2 tornado destroyed one single family dwelling, while another single family dwelling received major damage. Summary of events for the evening of June 8 and the early morning of June 9 1998: A classic southern plains severe weather event shaped up on the afternoon and evening of June 8 as a number of isolated severe thunderstorms developed over central Oklahoma to the east of a dryline. The first severe thunderstorm to affect eastern Oklahoma scraped the northwestern part of Osage County, causing a report of a severe thunderstorm gust. This storm quickly died as it entered Kansas. A second more serious severe thunderstorm formed west of Oklahoma City and tracked all the way to the Arkansas state line south of Fort Smith, traversing Pittsburg, Haskell, and Le Flore Counties. This storm travelled east along an instability axis and a warm front. From a radar perspective, this storm was impressive in that it kept a classic, well-defined hook on its entire journey across southeast Oklahoma. From a human perspective, this storm was impressive in that it produced ten tornadoes in southeast Oklahoma, hail as large as golfballs, damaging thunderstorm winds, and torrential flooding rains. A third cluster of severe thunderstorms developed over Creek County and moved east across Okmulgee, Muskogee, Cherokee, and Adair Counties before weakening as it entered Arkansas. These storms slowed their movement across Muskogee County and regeneration along the southwest flank of the storms caused torrential rainfalls that dumped nearly three inches of rain in northern Muskogee, southern Cherokee, southern Adair, and northern Sequoyah Counties. In addition to flooding rains, these storms produced hail as large as nickels and damaging thunderstorm winds. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado destroyed mobile homes, severely damaged permanent homes, snapped or uprooted numerous trees, destroyed barns and outbuildings, and blew down power poles and power lines. This tornado continued into Latimer County. EPISODE NARRATIVE: Elevated severe thunderstorms containing large hail developed north of a warm front that was moving slowly northward across eastern Oklahoma and west central Arkansas during the morning and early afternoon of the 10th. Another round of severe thunderstorms developed late in the afternoon as a dry line approached the area from the west. Extreme instability and strong vertical wind shear resulted in the development of long-lived supercell thunderstorms that moved across eastern Oklahoma and northwestern Arkansas during the late afternoon and evening. Several of these supercells became tornadic and a few produced long-lived damaging tornadoes. One such supercell developed and moved along the Oklahoma-Kansas border and then into southwestern Missouri. This storm produced a tornado in northeastern Craig County OK that remained on the ground for 29 miles in Oklahoma, continued for about 31 miles in Newton County MO, and finally dissipated about 15 miles into Barry County MO. It produced EF-4 damage in several locations, including Picher, a small town in north-central Ottawa County OK. Twenty-one fatalities, over 350 injuries, and an estimated $60 million in property damage resulted from this tornado in Oklahoma and Missouri. Six of the fatalities and about 150 injuries occurred in Picher OK. Other strong tornadoes developed and moved across portions of Pittsburg and Latimer Counties. A EF-2 tornado was on the ground for about eight miles west of McAlester, damaging numerous homes in its path. Another EF-2 tornado developed southwest of Hartshorne in Pittsburg County and moved 19 miles before dissipating just east of Yanush in Latimer County. Four injuries resulted from that tornado and numerous homes were severely damaged or destroyed. | |||||||||||

| Brief Description: EVENT NARRATIVE: This tornado continued from Pottawatomie county, moved through Seminole county and continued into Okfuskee County just east of Cromwell. This tornado lasted at least 30 miles, with significant damage along its entire path. At times, the tornado damage path widened up to a mile. The most significant damage was located north and northeast of Earlsboro near the Pottawatomie/Seminole county border. Here a two story home was destroyed except for a few interior walls. A pick-up truck was also lofted approximately a quarter of a mile, and a semi-trailer was lofted or rolled approximately 200 yards. Farther east along its path, seven high tension towers were downed. Several hangers were destroyed at the Seminole Municipal Airport north of Seminole, and one small aircraft was flipped onto one of the destroyed hangers. Two mobile homes were destroyed near the airport and one resident suffered a broken arm. Significant tree damage was reported along the entire track of the tornado, some of them debarked and stripped off all their branches. See the documentation by the NWS Tulsa office for information of this tornado in Okfuskee County. This tornado is labeled #J4. EPISODE NARRATIVE: A significant outbreak of severe thunderstorms and tornadoes affected a large part of northern, central, and southern Oklahoma. Tornadoes were most numerous across central and southern Oklahoma, with significant damage occurring over many areas. Severe thunderstorms erupted by mid afternoon across northern and western Oklahoma. Given the potent combination of ingredients in place, storms began to produce tornadoes quickly after initiation. Storm motions of 50 to 60 mph were common. During the mid afternoon hours, severe weather was confined to northern Oklahoma. It was there a long track supercell storm produced tornadoes near the Kansas border - including one rated EF3 - from near Wakita to north of Braman. The capping inversion that had delayed thunderstorm development into central Oklahoma weakened, allowing for explosive supercell development along the dry line along and west of the Interstate 35 corridor. Rapid development and intensification was common with the late afternoon storms, with storms becoming tornadic within a very short time after initiation. This round of storms would directly impact a large part of the Oklahoma City metro area at rush hour, and posed a significant threat to the area. The first tornado in this area occurred in Canadian County. During the next several hours, tornadoes were clustered around the metro area, and at times there were multiple significant damaging tornadoes occurring simultaneously. Several of the tornadoes had long tracks. Damage from the tornadoes was substantial, with numerous structures, vehicles, trees and power poles/lines significantly damaged or destroyed. One of the more intense tornadoes moved across Lake Thunderbird east of Norman destroying numerous boats. More storms developed across southwest and south central Oklahoma, and also quickly became tornadic. By 9 pm, 35 tornadoes had been reported. While the loss of three lives was tragic, the casualties could have been much higher given the storm's fast motions, their intensity, the time of day and the areas impacted. While exact monetary damage figures were not available, it is estimated that losses were in excess of $595 million. At least 450 sustained injuries, most of them minor. Unfortunately three people lost their lives. Note: The large number of injuries and tornadoes made it difficult to associate injuries with specific tornadoes. Injury numbers were included when we had confidence in the numbers. Note: The complex nature of storm evolutions and interactions made the job of classifying tornadoes difficult. This represents our best scientific assessment based on ground and aerial surveys, data from multiple radars, photographic and video evidence and anecdotal information. | |||||||||||

| Brief Description: EVENT NARRATIVE: This tornado continued from Pittsburg County. As it moved into Latimer County, the tornado destroyed a double-wide mobile home, severely damaged another home and barn, and rolled an F350 pickup truck about 50 yards. Numerous trees were snapped or uprooted as the tornado approached Yanush. In Yanush, about 50 homes were damaged, eight of those were destroyed along with one business. Numerous sheds, barns, and outbuildings were destroyed. Numerous trees and power lines were blown down. EPISODE NARRATIVE: Elevated severe thunderstorms containing large hail developed north of a warm front that was moving slowly northward across eastern Oklahoma and west central Arkansas during the morning and early afternoon of the 10th. Another round of severe thunderstorms developed late in the afternoon as a dry line approached the area from the west. Extreme instability and strong vertical wind shear resulted in the development of long-lived supercell thunderstorms that moved across eastern Oklahoma and northwestern Arkansas during the late afternoon and evening. Several of these supercells became tornadic and a few produced long-lived damaging tornadoes. One such supercell developed and moved along the Oklahoma-Kansas border and then into southwestern Missouri. This storm produced a tornado in northeastern Craig County OK that remained on the ground for 29 miles in Oklahoma, continued for about 31 miles in Newton County MO, and finally dissipated about 15 miles into Barry County MO. It produced EF-4 damage in several locations, including Picher, a small town in north-central Ottawa County OK. Twenty-one fatalities, over 350 injuries, and an estimated $60 million in property damage resulted from this tornado in Oklahoma and Missouri. Six of the fatalities and about 150 injuries occurred in Picher OK. Other strong tornadoes developed and moved across portions of Pittsburg and Latimer Counties. A EF-2 tornado was on the ground for about eight miles west of McAlester, damaging numerous homes in its path. Another EF-2 tornado developed southwest of Hartshorne in Pittsburg County and moved 19 miles before dissipating just east of Yanush in Latimer County. Four injuries resulted from that tornado and numerous homes were severely damaged or destroyed. | |||||||||||

| Brief Description: A major severe weather outbreak occurred across western and central Oklahoma from the afternoon of the 4th through the early morning of the 5th, resulting in 19 tornadoes, straight-line wind damage, hail as large as baseballs, and significant flooding across portions of Lincoln and Noble Counties, where numerous costly bridges were destroyed. Thunderstorms first developed over northwest Oklahoma during the early and mid-afternoon where hail larger than golf balls was reported in Major and Woodward Counties. The first of 19 tornadoes occurred at 1425 CST in Woods County 11 miles south-southwest of Dacoma. A media storm chaser observed this multiple vortex tornado as it touched down in southeastern Woods County and traveled northeast into western Alfalfa County before dissipating 4 miles northwest of Carmen. Damage was first reported south of Dacoma where an old abandoned house was damaged and a barn and garage were destroyed. As the tornado moved into western Alfalfa County, an office building at Carmen Field Limited Partnership and a local gas plant were completely destroyed. A modular home adjacent to the gas plant also had most of its roof blown off. Numerous witnesses described this tornado (F2) as very large and was at least a quarter of a mile wide. The 2nd tornado, an F0, developed on the salt flats 5 miles southeast of Cherokee in Alfalfa County and was seen by an Alfalfa County Sheriff's Deputy. The 3rd tornado was witnessed by a state trooper touching down very close to Highway 11, 5 miles west of Medford in Grant County, and was on the ground for less than one minute with no known damage (F0). As the thunderstorms associated with these tornadoes moved east, additional thunderstorms began to intensify farther south. Near Mountain Park in Kiowa County, Baseball size hail destroyed numerous car windshields. A short while longer, at 1638 CST, the 4th tornado was captured on video by a reliable storm chaser 9 miles southwest of Watonga in Blaine County. This tornado touched down for only a few seconds in an open field with no known damage (F0). Several storage buildings at a Lowe's Department Store in Ponca City in Kay County, were blown over by winds estimated between 80-90 mph. The 5th tornado touched down 2.5 miles southwest of Watonga in Blaine County and crossed US-270/281 two miles south of Watonga. The tornado continued to the northeast and finally dissipated about 9 miles east-northeast of Watonga. At least three homes suffered significant damage, one of which had its roof completely removed (F2). The 6th tornado was seen by an Oklahoma Highway Patrol Officer 5 miles north of Medicine Park in Comanche County touching down briefly in an open field with no known damage (F0). The 7th tornado, an F1, touched down 6 miles southwest of Dover in Kingfisher County and traveled northeast for 7 miles, crossing Highway 81 near the Cimarron River, and dissipating 2 miles southeast of Dover. One haybarn was destroyed, while 1 residence and 5 barns were damaged. Numerous trees and power lines were also downed. The 8th tornado, an F0, touched down just west of the intersection of US-277 and SH-8, 1 mile north of Cyril in Caddo County, and moved east for one-half mile knocking down trees and power lines and causing minor roof damage in the extreme northeastern portion of Cyril. While straight-line winds damaged a roof at the Farmers Coop Association building, and a trailer home in Guthrie in Logan County at 1745 CST, the 9th tornado touched down at 1747 CST on or just south of Lake Carl Blackwell in Payne County, and was observed by numerous people in and near Stillwater. The tornado moved northeast over the lake, crossed into extreme southern Noble County, and over Lake McMurtry. Minor damage was reported in northern Payne County, however the worst damage occurred in southern Noble County as the tornado moved off of Lake McMurtry and severely damaged a mobile home (F1). The 10th tornado (F2) was witnessed by 3 firefighters 1 mile south of Highway 277 on Lake Burtshi Road 9 miles west-southwest of Ninnekah in Grady County, and was on the ground for 1.5 miles. One mobile home was disintegrated, while 2 others nearby were flipped over. Many well-structured homes sustained minor roof damage, and numerous trees were blown over, some onto homes and one onto an RV. A storage building was also destroyed. The 11th tornado, also an F2, touched down in Grady County, 4.5 miles north of Middleburg, damaging several mobile homes and outbuildings. One mobile home was completely destroyed in the Bridge Creek area while two others were blown over. Scattered tree damage continued for 5 miles into McClain county just to the southwest of the Newcastle city limits. Wind damage continued into the south part of Newcastle causing damage to trees and power lines. In addition to the tornado damage, straight-line winds overturned several tractor-trailers 7 miles south of Tuttle, also in Grady County, and destroyed a barn in Dibble in McClain County. Lightning also struck a house on Broadway in Norman in Cleveland County, causing a small fire at 1900 CST. The 12th tornado (F0) developed at 1926 CST 3 miles north of Newcastle in McClain County, and was observed by people from Norman, Moore and Newcastle. This tornado touched down just northeast of the intersection of I-44 and North 32nd Street north of Newcastle, and moved north into extreme western Cleveland County near SW 149th St. and Meridian Avenue, in southwest Oklahoma City. Damage was primarily to trees. The 13th tornado was one of the most destructive tornadoes of the outbreak, developing over the city of Moore in Cleveland County about 1/2 mile north of SW 19th Ave, just east of Santa Fe Ave. The tornado tracked almost due north at first, and then curved slightly east of north. Many homes lost all or parts of their roofs, leaving them uninhabitable, and one home lost a portion of an exterior wall. Sections of roofs were also torn off of a few warehouses as the tornado crossed Shields Ave. and then dissipated just west of I-35. The worst damage occurred along NW 12th Ave to the west of Janaway where F2 damage was observed. In total, 10 single-family residences were either destroyed or severely damaged; 8 multi-family buildings were severely damaged; and hundreds of other homes and businesses sustained minor damage. Damage estimates were near 2 million dollars. The 14th tornado touched down near EW 106 road and NS 346 Road 4 miles southeast of Meeker in Lincoln County, where light damage occurred to many trees. The tornado then moved northeast crossing EW 347 south of US 62. Damage was observed from just south of this intersection southward for about one mile. Just south of the intersection, trees were downed and a house received damage to the roof and porch. F2 damage occurred about 1/2 mile south of US 62, where three homes received significant roof damage, and an RV was pushed over onto its side. The tornado crossed US 62 with light damage to trees and minor damage to a house along the highway. The tornado likely dissipated just northeast of the intersection of US 62 and NS 347 Road. The 15th tornado, also an F2, developed a few minutes after the last tornado about 7 miles west of Prague. This tornado touched down near NS 348 road about 1/2 mile north of EW 106 Road where a mobile home received light damage. The tornado moved northeast crossing near the intersection of EW 105 Road and NS 349 Road, then grew in size and intensity before crossing US 62. A mobile home along US 62 just west of NS 350 Road was destroyed. The metal frame that supported the home and most of the contents was deposited northwest of the original location up to 150 yards. Other debris was thrown north-northeast across US 62. The tornado then continued northeast and damage was noted for 3/4 of a mile along NS 350 Road centered on US 62. Slight damage to trees and outbuildings was observed along NS 352 Road approximately 2 miles north of US 62. The tornado probably dissipated northeast of this point, although roads became inaccessibe due to flooding and made it difficult to determine the exact location. In addition, a 6 mile long swath of damaging straight-line winds accompanied this tornado from 6 miles west of Prague to 3 miles northwest of Prague, resulting in massive tree damage. Damaging straight-line winds were also responsible for blowing down trees and power lines in Shawnee in Pottowatomie County at 2010 CST, and for a wind gust of 64 mph at 2020 CST, 4 miles west-southwest of Guthrie in Logan County, measured by Oklahoma Mesonet. Another tornado, the 16th of the outbreak, developed at about the same time 6 miles northwest of Prague, and moved northeast for 7 miles before dissipating 7 miles north-northeast of Prague. This tornado, rated an F1, touched down at the intersection of EW 102 Road and NS 350 Road where outbuildings received moderate damage. Less than 1/4 of a mile away on EW 102 Road, a mobile home was lifted and thrown east about 100 yards, uprooting a power pole while airborne. The mobile home was destroyed upon impact. All 6 family members who took shelter inside an interior closet were injured. All injuries were minor, except for the father who suffered broken ribs, a cracked pelvis and head injuries. He stayed overnight in a nearby hospital and was released the next day. As the tornado continued east-northeast along NS 352 Road, south of the community of Wilzetta, an outbuilding was unroofed, minor damage occurred to a house roof, and trees were uprooted. Tree and power line damage continued to about 2 or 3 miles east of Wilzetta. The tornado then turned more to the northeast as it crossed SH 99 where a mobile home received minor damage, 3 outbuildings were destroyed, a few logs at a sawmill were tossed, and trees were downed. Scattered tree damage was observed to just southwest of the intersection of NS 357 Road and EW 99 Road where the tornado lifted. In addition to the tornadoes near Prague, straight-line winds were responsible for downing numerous trees and awnings of several businesses in downtown Prague. Farther south in Pottawatomie County, 2 tornadoes (Numbers 17 and 18 of the outbreak) embedded in larger swaths of damaging straight-line winds, developed near Shawnee. The first one touched down 3 miles northwest of Shawnee and remained on the ground for 3 miles before dissipating 3 miles north of Shawnee. A large swath of damaging straight-line winds approximately 1 mile wide and 4 miles long accompanied this F1 tornado as it moved across northern portions of Shawnee. Extensive tree damage occurred on a private golf course just west of Acme road. Minor damage also occurred to the roof of the clubhouse and to the roof-mounted air conditioning unit. Widespread tree and roof damage also occurred in a subdivision south of 45th St. and west of Kickapoo. In addition to a mobile home being destroyed near the east end of the damage path, which is believed to be the result of a tornado, many other mobile homes nearby received minor damage. In addition, 1 mile southeast of Dale in Pottowatomie County, numerous trees and signs were either destroyed or uprooted along Interstate 40; a shed was destroyed, and a barn was unroofed along Highway 102. Oklahoma Mesonet also measured a wind gust of 72 mph at 2055 CST, 3 miles north-northwest of Shawnee. The 2nd tornado, also an F1 and the 18th tornado of the outbreak, developed in or very close to the Shawnee business district, moved east for 2 miles, and was also accompanied by a large area of damaging straight-line winds. The exact damage resulting from the tornado was difficult to assess, but it is believed it was limited to fallen trees, downed power lines, and minor roof and structural damage to many homes. The area of straight-line wind damage was approximately 2.5 miles wide and 5 miles long, and occurred from the western side of Shawnee to the eastern side of Shawnee. Damage included widespread fallen trees in a suburban area north of Highland extending several blocks either side of Kickapoo, in the Woodland Park area, Boy Scout Park, and in the rural area along and south of Farrel Road between Harrison and Bryan. One tree fell on and heavily damaged the Beard House, a local landmark that was the first homestead built in Shawnee in 1895. An east-facing cinder block wall of a warehouse was blown outward in the vicinty of Minnesota and Pennsylvania Streets, and structural damage occurred to many buildings in downtown Shawnee, including toppled brick walls and broken windows. The combination of widespread straight-line wind damage and a tornado resulted in major damage over a very large area. The 19th and last tornado of the outbreak touched down 5 miles west-northwest of Little, near the intersection of EW 114 Road and NS 351 Road in northwestern Pottowatomie County, where minor tree damage was observed. The tornado, an F3, then increased in size to approximately a 1/2 mile wide as it moved northeast. As it crossed NS 351 Road and then EW 113 Road, a number of outbuildings were heavily damaged, and trees were snapped. Three mobile homes received light damage near the north edge of the path, and 3 other homes received light damage to shingles. The tornado crossed Interstate 40 blowing over a truck which was carrying hazardous materials. The tornado then continued northeast unroofing a mobile home, causing damage to trees and destroying a number of outbuilding before crossing the North Canadian River into northeast Pottawatomie County. Along EW 110 Road, significant tree damage was observed, and a barn was partially unroofed. The community of Center View near the intersection of SH 99 and EW 109 Road was then hard hit with most of the damage south and east of this intersection. From the debris pattern, the center of the tornado crossed Highway 99 one-half mile south of EW 109 Road. A house along Highway 99 was unroofed and lost most of its exterior walls. Three homes suffered major damage along EW 109 Road. Two other homes suffered significant damage. As the tornado continued moving northeast another home suffered significant roof damage, and the south facing brick wall was buckled. The garage was destroyed. Steel and cinder block from the garage were impaled in a tree. There was also significant damage to large trees. Farther northeast, damage to a roof was noted, and a large number of power lines were downed along NS 357 Road near the intersection of EW 108 Road. One outbuilding was damaged, and light damage was observed in trees just south of EW 107 Road. In total, at least 60 homes or businesses were damaged. Major flooding developed across Noble, Lincoln, and Payne Counties shortly after midnight on the 5th. Red Rock Creek and Black Bear Creek near Red Rock in Payne County, overflowed their banks between Highway 77 and Interstate 35 washing away several small bridges. Damage was estimated at 200 thousand dollars. Six to seven inches of rain fell across a large portion of Lincoln County. At least 3 bridges were washed away by the floods including 1 bridge 1 mile east of Kendrick, and dozens of roads suffered erosion damage. Creeks also overflowed their banks in Stroud, Davenport, and Agra. At least 500 thousand dollars in damage resulted. Between 4 and 5 inches of rain fell across Payne County forcing the Cu Chee Creek to overflow its banks, flooding many roads in Cushing and Stillwater. | |||||||||||

| Brief Description: EVENT NARRATIVE: The tornado continued into Pushmataha county before lifting 2.75 miles WSW of Adel. In Atoka County, three houses were damaged. The roof was removed and some of the exterior walls on one well-built home were collapsed. Numerous trees were uprooted or snapped above the ground. Monetary damage were estimated. EPISODE NARRATIVE: A powerful storm system strengthened over the central Plains during the day on Saturday, drawing rich gulf moisture north into eastern Oklahoma. A surface low pressure developed with a trailing cold front that moved quickly through western Oklahoma, and a dry line extending to the east of the cold front. Isolated severe thunderstorms developed near Hughes county early in the afternoon, with large hail reported in a few locations. Later in the afternoon, supercells over eastern Oklahoma expanded southwest. One supercell developed over far eastern Atoka county, producing a tornado near Daisy and large hail. Damage was reported with the tornado, but there were no injuries. Monetary damages were estimated. | |||||||||||

| Brief Description: A major severe weather outbreak occurred across western and central Oklahoma from the afternoon of the 4th through the early morning of the 5th, resulting in 19 tornadoes, straight-line wind damage, hail as large as baseballs, and significant flooding across portions of Lincoln and Noble Counties, where numerous costly bridges were destroyed. Thunderstorms first developed over northwest Oklahoma during the early and mid-afternoon where hail larger than golf balls was reported in Major and Woodward Counties. The first of 19 tornadoes occurred at 1425 CST in Woods County 11 miles south-southwest of Dacoma. A media storm chaser observed this multiple vortex tornado as it touched down in southeastern Woods County and traveled northeast into western Alfalfa County before dissipating 4 miles northwest of Carmen. Damage was first reported south of Dacoma where an old abandoned house was damaged and a barn and garage were destroyed. As the tornado moved into western Alfalfa County, an office building at Carmen Field Limited Partnership and a local gas plant were completely destroyed. A modular home adjacent to the gas plant also had most of its roof blown off. Numerous witnesses described this tornado (F2) as very large and was at least a quarter of a mile wide. The 2nd tornado, an F0, developed on the salt flats 5 miles southeast of Cherokee in Alfalfa County and was seen by an Alfalfa County Sheriff's Deputy. The 3rd tornado was witnessed by a state trooper touching down very close to Highway 11, 5 miles west of Medford in Grant County, and was on the ground for less than one minute with no known damage (F0). As the thunderstorms associated with these tornadoes moved east, additional thunderstorms began to intensify farther south. Near Mountain Park in Kiowa County, Baseball size hail destroyed numerous car windshields. A short while longer, at 1638 CST, the 4th tornado was captured on video by a reliable storm chaser 9 miles southwest of Watonga in Blaine County. This tornado touched down for only a few seconds in an open field with no known damage (F0). Several storage buildings at a Lowe's Department Store in Ponca City in Kay County, were blown over by winds estimated between 80-90 mph. The 5th tornado touched down 2.5 miles southwest of Watonga in Blaine County and crossed US-270/281 two miles south of Watonga. The tornado continued to the northeast and finally dissipated about 9 miles east-northeast of Watonga. At least three homes suffered significant damage, one of which had its roof completely removed (F2). The 6th tornado was seen by an Oklahoma Highway Patrol Officer 5 miles north of Medicine Park in Comanche County touching down briefly in an open field with no known damage (F0). The 7th tornado, an F1, touched down 6 miles southwest of Dover in Kingfisher County and traveled northeast for 7 miles, crossing Highway 81 near the Cimarron River, and dissipating 2 miles southeast of Dover. One haybarn was destroyed, while 1 residence and 5 barns were damaged. Numerous trees and power lines were also downed. The 8th tornado, an F0, touched down just west of the intersection of US-277 and SH-8, 1 mile north of Cyril in Caddo County, and moved east for one-half mile knocking down trees and power lines and causing minor roof damage in the extreme northeastern portion of Cyril. While straight-line winds damaged a roof at the Farmers Coop Association building, and a trailer home in Guthrie in Logan County at 1745 CST, the 9th tornado touched down at 1747 CST on or just south of Lake Carl Blackwell in Payne County, and was observed by numerous people in and near Stillwater. The tornado moved northeast over the lake, crossed into extreme southern Noble County, and over Lake McMurtry. Minor damage was reported in northern Payne County, however the worst damage occurred in southern Noble County as the tornado moved off of Lake McMurtry and severely damaged a mobile home (F1). The 10th tornado (F2) was witnessed by 3 firefighters 1 mile south of Highway 277 on Lake Burtshi Road 9 miles west-southwest of Ninnekah in Grady County, and was on the ground for 1.5 miles. One mobile home was disintegrated, while 2 others nearby were flipped over. Many well-structured homes sustained minor roof damage, and numerous trees were blown over, some onto homes and one onto an RV. A storage building was also destroyed. The 11th tornado, also an F2, touched down in Grady County, 4.5 miles north of Middleburg, damaging several mobile homes and outbuildings. One mobile home was completely destroyed in the Bridge Creek area while two others were blown over. Scattered tree damage continued for 5 miles into McClain county just to the southwest of the Newcastle city limits. Wind damage continued into the south part of Newcastle causing damage to trees and power lines. In addition to the tornado damage, straight-line winds overturned several tractor-trailers 7 miles south of Tuttle, also in Grady County, and destroyed a barn in Dibble in McClain County. Lightning also struck a house on Broadway in Norman in Cleveland County, causing a small fire at 1900 CST. The 12th tornado (F0) developed at 1926 CST 3 miles north of Newcastle in McClain County, and was observed by people from Norman, Moore and Newcastle. This tornado touched down just northeast of the intersection of I-44 and North 32nd Street north of Newcastle, and moved north into extreme western Cleveland County near SW 149th St. and Meridian Avenue, in southwest Oklahoma City. Damage was primarily to trees. The 13th tornado was one of the most destructive tornadoes of the outbreak, developing over the city of Moore in Cleveland County about 1/2 mile north of SW 19th Ave, just east of Santa Fe Ave. The tornado tracked almost due north at first, and then curved slightly east of north. Many homes lost all or parts of their roofs, leaving them uninhabitable, and one home lost a portion of an exterior wall. Sections of roofs were also torn off of a few warehouses as the tornado crossed Shields Ave. and then dissipated just west of I-35. The worst damage occurred along NW 12th Ave to the west of Janaway where F2 damage was observed. In total, 10 single-family residences were either destroyed or severely damaged; 8 multi-family buildings were severely damaged; and hundreds of other homes and businesses sustained minor damage. Damage estimates were near 2 million dollars. The 14th tornado touched down near EW 106 road and NS 346 Road 4 miles southeast of Meeker in Lincoln County, where light damage occurred to many trees. The tornado then moved northeast crossing EW 347 south of US 62. Damage was observed from just south of this intersection southward for about one mile. Just south of the intersection, trees were downed and a house received damage to the roof and porch. F2 damage occurred about 1/2 mile south of US 62, where three homes received significant roof damage, and an RV was pushed over onto its side. The tornado crossed US 62 with light damage to trees and minor damage to a house along the highway. The tornado likely dissipated just northeast of the intersection of US 62 and NS 347 Road. The 15th tornado, also an F2, developed a few minutes after the last tornado about 7 miles west of Prague. This tornado touched down near NS 348 road about 1/2 mile north of EW 106 Road where a mobile home received light damage. The tornado moved northeast crossing near the intersection of EW 105 Road and NS 349 Road, then grew in size and intensity before crossing US 62. A mobile home along US 62 just west of NS 350 Road was destroyed. The metal frame that supported the home and most of the contents was deposited northwest of the original location up to 150 yards. Other debris was thrown north-northeast across US 62. The tornado then continued northeast and damage was noted for 3/4 of a mile along NS 350 Road centered on US 62. Slight damage to trees and outbuildings was observed along NS 352 Road approximately 2 miles north of US 62. The tornado probably dissipated northeast of this point, although roads became inaccessibe due to flooding and made it difficult to determine the exact location. In addition, a 6 mile long swath of damaging straight-line winds accompanied this tornado from 6 miles west of Prague to 3 miles northwest of Prague, resulting in massive tree damage. Damaging straight-line winds were also responsible for blowing down trees and power lines in Shawnee in Pottowatomie County at 2010 CST, and for a wind gust of 64 mph at 2020 CST, 4 miles west-southwest of Guthrie in Logan County, measured by Oklahoma Mesonet. Another tornado, the 16th of the outbreak, developed at about the same time 6 miles northwest of Prague, and moved northeast for 7 miles before dissipating 7 miles north-northeast of Prague. This tornado, rated an F1, touched down at the intersection of EW 102 Road and NS 350 Road where outbuildings received moderate damage. Less than 1/4 of a mile away on EW 102 Road, a mobile home was lifted and thrown east about 100 yards, uprooting a power pole while airborne. The mobile home was destroyed upon impact. All 6 family members who took shelter inside an interior closet were injured. All injuries were minor, except for the father who suffered broken ribs, a cracked pelvis and head injuries. He stayed overnight in a nearby hospital and was released the next day. As the tornado continued east-northeast along NS 352 Road, south of the community of Wilzetta, an outbuilding was unroofed, minor damage occurred to a house roof, and trees were uprooted. Tree and power line damage continued to about 2 or 3 miles east of Wilzetta. The tornado then turned more to the northeast as it crossed SH 99 where a mobile home received minor damage, 3 outbuildings were destroyed, a few logs at a sawmill were tossed, and trees were downed. Scattered tree damage was observed to just southwest of the intersection of NS 357 Road and EW 99 Road where the tornado lifted. In addition to the tornadoes near Prague, straight-line winds were responsible for downing numerous trees and awnings of several businesses in downtown Prague. Farther south in Pottawatomie County, 2 tornadoes (Numbers 17 and 18 of the outbreak) embedded in larger swaths of damaging straight-line winds, developed near Shawnee. The first one touched down 3 miles northwest of Shawnee and remained on the ground for 3 miles before dissipating 3 miles north of Shawnee. A large swath of damaging straight-line winds approximately 1 mile wide and 4 miles long accompanied this F1 tornado as it moved across northern portions of Shawnee. Extensive tree damage occurred on a private golf course just west of Acme road. Minor damage also occurred to the roof of the clubhouse and to the roof-mounted air conditioning unit. Widespread tree and roof damage also occurred in a subdivision south of 45th St. and west of Kickapoo. In addition to a mobile home being destroyed near the east end of the damage path, which is believed to be the result of a tornado, many other mobile homes nearby received minor damage. In addition, 1 mile southeast of Dale in Pottowatomie County, numerous trees and signs were either destroyed or uprooted along Interstate 40; a shed was destroyed, and a barn was unroofed along Highway 102. Oklahoma Mesonet also measured a wind gust of 72 mph at 2055 CST, 3 miles north-northwest of Shawnee. The 2nd tornado, also an F1 and the 18th tornado of the outbreak, developed in or very close to the Shawnee business district, moved east for 2 miles, and was also accompanied by a large area of damaging straight-line winds. The exact damage resulting from the tornado was difficult to assess, but it is believed it was limited to fallen trees, downed power lines, and minor roof and structural damage to many homes. The area of straight-line wind damage was approximately 2.5 miles wide and 5 miles long, and occurred from the western side of Shawnee to the eastern side of Shawnee. Damage included widespread fallen trees in a suburban area north of Highland extending several blocks either side of Kickapoo, in the Woodland Park area, Boy Scout Park, and in the rural area along and south of Farrel Road between Harrison and Bryan. One tree fell on and heavily damaged the Beard House, a local landmark that was the first homestead built in Shawnee in 1895. An east-facing cinder block wall of a warehouse was blown outward in the vicinty of Minnesota and Pennsylvania Streets, and structural damage occurred to many buildings in downtown Shawnee, including toppled brick walls and broken windows. The combination of widespread straight-line wind damage and a tornado resulted in major damage over a very large area. The 19th and last tornado of the outbreak touched down 5 miles west-northwest of Little, near the intersection of EW 114 Road and NS 351 Road in northwestern Pottowatomie County, where minor tree damage was observed. The tornado, an F3, then increased in size to approximately a 1/2 mile wide as it moved northeast. As it crossed NS 351 Road and then EW 113 Road, a number of outbuildings were heavily damaged, and trees were snapped. Three mobile homes received light damage near the north edge of the path, and 3 other homes received light damage to shingles. The tornado crossed Interstate 40 blowing over a truck which was carrying hazardous materials. The tornado then continued northeast unroofing a mobile home, causing damage to trees and destroying a number of outbuilding before crossing the North Canadian River into northeast Pottawatomie County. Along EW 110 Road, significant tree damage was observed, and a barn was partially unroofed. The community of Center View near the intersection of SH 99 and EW 109 Road was then hard hit with most of the damage south and east of this intersection. From the debris pattern, the center of the tornado crossed Highway 99 one-half mile south of EW 109 Road. A house along Highway 99 was unroofed and lost most of its exterior walls. Three homes suffered major damage along EW 109 Road. Two other homes suffered significant damage. As the tornado continued moving northeast another home suffered significant roof damage, and the south facing brick wall was buckled. The garage was destroyed. Steel and cinder block from the garage were impaled in a tree. There was also significant damage to large trees. Farther northeast, damage to a roof was noted, and a large number of power lines were downed along NS 357 Road near the intersection of EW 108 Road. One outbuilding was damaged, and light damage was observed in trees just south of EW 107 Road. In total, at least 60 homes or businesses were damaged. Major flooding developed across Noble, Lincoln, and Payne Counties shortly after midnight on the 5th. Red Rock Creek and Black Bear Creek near Red Rock in Payne County, overflowed their banks between Highway 77 and Interstate 35 washing away several small bridges. Damage was estimated at 200 thousand dollars. Six to seven inches of rain fell across a large portion of Lincoln County. At least 3 bridges were washed away by the floods including 1 bridge 1 mile east of Kendrick, and dozens of roads suffered erosion damage. Creeks also overflowed their banks in Stroud, Davenport, and Agra. At least 500 thousand dollars in damage resulted. Between 4 and 5 inches of rain fell across Payne County forcing the Cu Chee Creek to overflow its banks, flooding many roads in Cushing and Stillwater. | |||||||||||
