Brief Description: EVENT NARRATIVE: A damage survey conducted by the National Weather Service Forecast office in Columbia, South Carolina, confirmed that an EF3 tornado had tracked across far southern Wilkes county causing considerable damage along its path. The tornado continued its east-southeastward track into extreme northeastern McDuffie county. The total tornado path length was 18.6 miles. The tornado initially touched down in the Tyrone community in southwest Washington county. Here a cinder block home was completely destroyed with the cinder block debris blown downstream nearly 1/2 mile. Fifteen other homes along the path of the tornado sustained moderate to major damage from the tornado. Nineteen outbuildings and a commercial chicken house was destroyed. In addition, a steeple was blown off a church and a 2-ton truck was moved 60 feet. The maximum path width was approximately 1/2 mile with maximum winds estimated to be 160 mph. EPISODE NARRATIVE: A strong cold front accompanied and deep negatively tilted upper trough through the eastern U.S. from the 18th into the 19th. An unseasonably warm and unstable air mass developed in advance of the cold front during the late afternoon and early evening across north and central Georgia as warm, moist air rode northward into Georgia on a strong low-level jet. Afternoon temperatures in the 70s and dewpoints in the 60s, combined with strong shear and moderate instability, resulted in the development of numerous supercell thunderstorms from mid-afternoon until a few hours after midnight on the 19th. Ten tornadoes, ranging in scale from EF0 to EF3 tracked across several north and central Georgia counties. The worst tornadoes affected the east central Georgia counties of Jasper, Putnam, Hancock, and Jasper. A death was observed in Hancock county with an EF3 tornado and several injuries were reported from Putnam and Hancock counties. In addition to the tornadoes, very large hail occurred with several of the thunderstorms, including four-inch diameter hail in Coweta and Fayette counties just south of Atlanta. Numerous reports of golf ball and larger-sized hail were received. The event resulted in millions of dollars of damage and the destruction of several homes in north and central Georgia counties. | |||||||||||

Brief Description: EVENT NARRATIVE: NWS survey found a tornado damage track in far southern and southeast Elbert County. The tornado, which was spawned from a supercell, touched down southeast of Fortsonia near the intersection of River Rd and Flatwoods Rd. As the tornado tracked east along River Rd, damage was mainly confined to trees and power lines. The tornado began to take on a more east/southeast track near the intersection of River Rd and Balchin Rd, remaining just north of the Wilkes County line. Intensification occurred just west of highway 79 near its intersection with Cooter Creek Rd. The tornado continued to track east southeast, snapping or uprooting numerous trees between Cooter Creek Rd and the Broad River. Two homes received heavy roof damage consistent with EF2 intensity on Bramblett Circle along the Broad River. A boat dock was also lifted and tossed 25 feet in this area. The tornado continued to blow down trees before finally lifting in Bobby Brown State Park in the extreme southeast corner of the county. EPISODE NARRATIVE: Several supercell thunderstorms affected the mountains and foothills of extreme northeast Georgia during the afternoon and early evening hours. Very large hail, damaging winds and a few tornadoes accompanied the storms. | |||||||||||

Brief Description: EVENT NARRATIVE: A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that yet a third tornado touched down in Hancock county within a 15 minute period of time. However, this tornado was determined to be an EF3 tornado. This tornado touched down about halfway between Sparta and Culverton in east central Hancock county. The tornado was determined to have a maximum path width of 1/2 mile with maximum winds of 160 mph. Much of the damage occurred along Dunn and Hickory Grove Roads. Along the path of the tornado, one 4000 square foot site-built home was completely destroyed. The debris from the home was scattered across an area up to 400 feet downstream. A resident of this home suffered serious injuries. Another nearby double-wide mobile home was also completely destroyed. Two other nearby homes on Dunn suffered minor damage and two additional homes on Youngblood Road toward Jewell suffered extensive roof damage. A swath of 116 mature pecan trees at a pecan orchard on Hickory Grove road were flattened. These were owned by a resident adjacent to one of the damaged homes on Hickory Grove Road. One of the homeowners also lost a Shetland pony during the tornado. EPISODE NARRATIVE: A vigorous upper closed low was moving from the mid-south and Mississippi valley region into the mid-Atlantic and southeast U.S. A strong cold front accompanied the upper system. A strong low-level jet in advance of these weather systems transported warm, moist Gulf air northward into the region. With strong dynamics, hence shear, combined with an unusually moist, unstable atmosphere, the atmosphere was primed for a major weather outbreak. One round of thunderstorms passed through north Georgia during the early morning hours. A few minor severe weather events accompanied this system in northwest Georgia. Partial clearing followed the morning convection, allowing temperatures to soar into the mid 70s across much of north and central Georgia in advance of the main weather system. Scattered to numerous discrete supercell thunderstorms developed during mid-afternoon in northwest Georgia and progressed east and southeast across the remaining portions of the county warning area during the evening hours. Severe thunderstorms and tornadoes lingered into the early morning hours of the 11th across the southern counties of central Georgia. During the eight hour period from 5 pm EDT on April 10th to 1 am EDT on April 11th, a total of 14 tornadoes were confirmed to have touched down in north and central Georgia causing millions in damages. While some injuries were observed, no deaths were observed. | |||||||||||

Brief Description: EVENT NARRATIVE: A storm survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that an EF3 tornado touched down approximately five miles east-southeast of Sparta, or about three miles east of the intersection of Georgia Highway 15 and 16. The tornado then moved along a nearly eight-mile long path across far southeast Hancock county and continued into extreme southern Warren county and then into extreme northwest Glascock county. The total tornado path length was nearly 11 miles long. The maximum path width was estimated to be 500 yards with maximum winds of 140 mph. A church, two site-built homes, and four mobile homes were completely destroyed in the Hickory Grove Community. One fatality and three injuries occurred where the mobile homes were destroyed. Hundreds of trees were either uprooted or snapped along the path of the tornado. EPISODE NARRATIVE: A strong cold front accompanied and deep negatively tilted upper trough through the eastern U.S. from the 18th into the 19th. An unseasonably warm and unstable air mass developed in advance of the cold front during the late afternoon and early evening across north and central Georgia as warm, moist air rode northward into Georgia on a strong low-level jet.

Brief Description: EVENT NARRATIVE: A damage survey conducted by the National Weather Service in Peachtree City, GA concluded that an EF2 tornado tracked across eastern Warren county, touching down about four miles east-northeast of Warrenton, and continued into McDuffie county, terminating about 6 miles northeast of Thomson near Interstate-20. The overall tornado path length was 15 miles, but only about 2.5 miles of the path occurred within Warren county. The maximum path width was 448 yards or about one-quarter nautical mile. The tornado tracked very close to U.S. Highway 278 or Georgia Highway 12, the main highway between Warrenton and Thomson. The most significant damage occurred to the Briarwood Academy on U.S. Highway 278. In addition, a number of homes, mostly double-wide mobile homes, sustained significant damage between Warrenton and the McDuffie county line, especially on the northeast side of Warrenton. Most of the damage was in the Camak Road and Thomson Highway area. One double-wide mobile home was completely destroyed with only the base slab left standing. There were eight homes with major damage, 13 with moderate damage, and 17 with minor damage. Three individuals sustained minor injuries from flying glass and debris. Dozens of trees and power lines were down along the path of the tornado. EPISODE NARRATIVE: A major, negatively tilted and closed upper trough rotated through the mid-south and southeast U.S. on March 1st. A 150kt jet was located over the region at 250mb with a strong 50kt low-level jet from central Alabama into central Tennessee. A wedge of cool air was present over much of north central and northeast Georgia. Rain, which spread over this area early in the day, helped enhance the wedge of cool air. Little to no severe weather was noted north of the wedge boundary across north Georgia where the air mass remained relatively cool and stable. Meanwhile...a warm, humid air mass was present across much of central and south Georgia where dewpoints had risen well into the 60s during the afternoon. The strong upper dynamics present over this region combined with the instability just south of the wedge provided a very favorable environment for long lived, strong tornadoes. A total of 14 tornadoes affecting 17 counties tracked across central and east central Georgia and within the Peachtree City, Georgia county warning area during the late afternoon and evening hours of March 1st. This was the second greatest number of tornadoes recorded to have occurred in the Peachtree City, Georgia forecast area within a 24-hour period, second only to the 16 tornadoes, affecting 18 counties, associated with Hurricane Katrina on August 29, 2005. The March 1st tornadoes spanned an area from Stewart county in the far southwest part of the county warning area to Warren county in the far east central portion of the county warning area. The first tornado touched down in Stewart county at 4:11 pm EST and the last tornado lifted in Marion county at 10:55 pm EST. By far the hardest hit county was Sumter county, and especially the city of Americus, where hundreds of homes and business, including the regional hospital, were heavily damaged or destroyed. Additional tornadoes were reported further south in Tallahassee and Jacksonville's, Florida's forecast areas. Federal disaster assistance had been approved for 1,836 households across the state for a total of $14.2 million. Another $5.8 million had been approved for public assistance of debris removal and to repair infrastructure. The Small Business Association also approved $7 million in disaster assistance loans. Overall damages, however, are estimated to be several hundred million. Substantial rainfall fell across much of the state, but rainfall amounts of three to five inches were common across central and east central areas. The heaviest rainfall fell in the Hancock, Putnam, and Baldwin county areas, where some spots received in excess of six inches of rain. Some flooding was reported in these areas. | |||||||||||

Brief Description: EVENT NARRATIVE: A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that an EF2 tornado touched down near Holland Park Drive in east central Gwinnett county, or about five miles northwest of Dacula. The tornado then tracked slightly over two miles to the north-northeast between Mountain View High School and Twin Rivers Middle School before lifting just east of the intersection of Gravel Springs Road and Interstate-85. The tornado was determined to have a path width of 300 yards with maximum wind gusts of 130 mph. Extensive damage was observed to homes mainly in the Kirkstone Subdivision of Buford. A total of 56 homes and one business along the path of the tornado sustained at least minor damage. Of these, 15 to 20 homes sustained major damage or were destroyed and thus were declared uninhabitable. One of these homes collapsed on itself. Damage to homes and property was estimated by the state insurance commissioner to exceed $5 million. EPISODE NARRATIVE: A deep full-latitude upper trough was sweeping from the central into the eastern U.S. The trough brought a quick transition to the eastern U.S. from mild fall temperatures to an extended period of well below normal temperatures. As the trough swept through the southeastern U.S. on November 30th, it took on a significant negative tilt. Although only marginal instability was noted because of extensive pre-frontal cloud cover and light to moderate rain showers, a strong 50-60kt low-level jet accompanied the trough as it rotated through Georgia during the afternoon of November 30th. This was sufficient combined with minimal instability (CAPE) in place at the time to support the development of a fairly well marked, yet very narrow, quasi-linear convective system (QLCS) which spawned two tornadoes, one an EF2 causing extensive damage to homes in Gwinnett county, and another weaker tornado in Henry county. In addition, the squall line or QLCS also produced numerous damaging wind events across north and central Georgia. | |||||||||||
