 Brief Description: One of the most potent tornadoes in recorded history in the state of Maryland tracked for 2 and 1/4 miles through the Mystic Kane and Four Seasons subdivisions just off state route 32 northwest of Gamber. The tornado was a strong F3 (180 mph estimated winds) with multiple vortices. Homes and trees struck by individual vortices sustained the worst damage. There were several eyewitness accounts of the tornado/funnel cloud shortly before touchdown. In all, 66 structures sustained damage. Twelve single-family homes were destroyed, five which lost most of the second story and garages. Three persons were injured. Two children were injured when the tornado blew them out of the second level of one of the homes. Their father suffered cuts and bruises when a wall partially collapsed on him while he was trying the rescue the children. Another dozen homes were deemed temporarily uninhabitable with substantial roof and siding damage. An additional 37 homes, a couple of apartments, and another barn received some damage. Many material items were sucked out of the homes, from bicycles to jewelry. Several automobiles were damaged by fallen and/or flying debris. Debris littered the ground for miles. A barn along route 32 was completely destroyed, and pieces of it were found as far away as 3.5 miles to the southeast of the barn's original location. Dozens of trees were snapped, shredded, debarked, and uprooted. Corn stalks were sucked up leaving six inch stubs as the tornado crossed a field west of route 32. A corn stalk was embedded into the wall of a house 1/2 mile away from the stalk's original location. Numerous airborne missiles (large and small) were generated, puncturing holes into homes and becoming embedded into the ground. A refrigerator was found wrapped around a mailbox. A van was dragged 50 feet, then flipped over two times. Other vehicles were also damaged.

 Brief Description: Thunderstorms spawned a strong F3 tornado in southern Lebanon County during the afternoon of July 14. The tornado first touched down in far western Lebanon County at 3:05 pm EDT, about 1 mile west of the town of Campbelltown. The tornado traveled east, and struck a housing development about one quarter mile south of Route 322. A total of 32 homes were destroyed, with another 37 homes sustaining significant damage. An additional 50 homes and 9 farm buildings in the area were damaged by downburst winds associated with the thunderstorm which spawned the tornado. The tornado continued along a path to the east for seven and one half miles. The tornado crossed Route 322 west of Mount Pleasant, and continued east, mainly across fields, until it lifted up about 2 miles northwest of the town of Cornwall at 3:15 pm EDT. The width of the tornado was one quarter mile. Although the tornadic damage was confined to the path described, additional damage occurred outside this path, again associated with downburst winds from the parent thunderstorm. Winds were estimated between 175 and 200 MPH, making this a strong F3 tornado on the Fujita scale. The tornado injured 24 persons, one critically. There were no deaths. The American Red Cross opened a mass care center, where over 50 people required assistance with sheltering. Between 25,000 and 30,000 customers lost power in Lebanon and Berks Counties as a result of the storms.

 Brief Description: A tornado crossed into Howard County from Laurel and remained on the ground until it dissipated about 1 mile east of Columbia. Several townhomes in North Laurel were damaged and trees were downed along the remainder of its path. Severe thunderstorms moved through Central Maryland during the early evening of the 24th. One thunderstorm produced a devastating F3 tornado which was on the ground for 17.5 miles from College Park in Prince George's County to just east of Columbia in Howard County. Multiple vortices were reported with the tornado at times. The tornado first touched down in Northwest Branch Stream Valley Park just west of Hyattsville. It rapidly strengthened to an F3 tornado with winds up to 200 MPH. The damage path ranged in width from 100 to 200 yards. The tornado crossed the intersection of Adelphi Road and University Boulevard into the western campus of the University of Maryland. Ten trailers being used as a temporary office for the Maryland Fire and Rescue Institute were completely destroyed by the twister. Debris from the trailers such as video tapes and pieces of paper were found up to 60 miles away in Northern Baltimore and Harford Counties in addition to extreme southeast Pennsylvania. Four of the six people inside the trailers were injured, one seriously. One staff member was thrown free of the destruction and was found in a dumpster nearby. Another person dug their hands into the carpet and held on as their feet were being pulled up in the air by the tornado. The other four occupants, including one child, took shelter under desks and survived. Two University of Maryland students who were visiting their father who worked in the trailers left by car shortly before the tornado hit. The two sisters, ages 20 and 23, were killed when the tornado picked up their car outside of Denton Hall and threw it either around or over an eight-story dorm. They died instantly when their car crashed into a wooded area 300 yards from the road. Most of the other buildings on the campus in the path of the storm were made of brick and suffered only minor to moderate damage, such as Denton Hall Dormitory, Easton Hall Dormitory and Dining Hall, and the President's Mansion. A parking lot outside of Denton Hall full of cars was also hit by the tornado. At least 200 vehicles in the parking lot were damaged, including at least 100 that were blown into and onto other vehicles. At least twenty cars were totaled and one car was partially ripped apart. The woods behind the parking lot were nearly flattened. The bubble roof of the football practice facility near Byrd Stadium was removed. Forty-eight people on campus, including 25 students, were injured by flying debris as the twister downed trees and ripped pieces of siding and roofing off buildings. In addition, residential areas near the campus, including the University Courtyard Apartments sustained damage. A total of 3000 students were left temporarily homeless after two dorms and an off-campus housing unit were evacuated due to storm damage. During the recovery effort, a 78-year-old firefighter who responded to the tragedy at the University died of a heart attack shortly after returning from the scene. The tornado moved north-northeast off the campus and crossed University Boulevard at the intersection of Metzerott Road. The steeple of a church was removed and cars were flipped near the intersection. Power lines and trees were also downed. The twister continued through Paint Branch Stream Valley Park where it downed numerous trees. The tornado weakened to F2 strength before it crossed Interstate 95/495 just west of the Route 1 interchange. It was remarkable that even though the highway was filled with bumper to bumper rush hour traffic, the only damage reported was a flipped tractor trailer. The next area hit by the tornado was the community of Cherry Hill. Several trees and power lines were downed onto roads and houses just west of Baltimore Avenue, including the Chestnut Hills subdivision. Several businesses along Route 1 sustained minor damage, and three additional buildings lost portions of their roofs. Three employees of a business in the Chestnut Hills Shopping Center were injured by flying glass after the windows on the front of the store were shattered. The tornado moved across the National Agricultural Research Center and caused over $40 million dollars in damage. Thirty greenhouses were damaged and several long term studies inside were destroyed. Fifteen other buildings west of Route 1 suffered minor to moderate damage. Numerous trees, including a row of historic willow oaks, were downed. Over 65 vehicles in the employee parking lot were damaged by flying debris. Eleven of these vehicles were totaled. Just north of the research center, "stunning" tree and power line damage was reported at the intersection of Sellman and Montgomery Roads. The tornado tracked across Powder Mill Road and ripped the roof off an office building at the intersection of Cedar Lane. It continued across the Beltsville Heights development and caused damage to the roof at Martin Luther King Elementary School. The tornado continued moving north-northeast toward Laurel. The continuation of the damage path was located at the Virginia Manor Industrial Park on Van Dusen Road where several trees were downed. The tornado was spotted as it moved past Laurel Hospital and it caused minor damage in the Village at Wellington subdivision nearby. The next concentrated area of damage was found at Laurel High School. An annex with 6 classrooms was heavily damaged. The roof was ripped off three of the classrooms and three people inside the structure were injured by flying debris. Significant damage was also reported to the athletic fields behind the school. The tornado moved northeast across the Fairlawn development where it damaged several homes. One home on 10th Street was destroyed after the twister removed the roof and an outside wall. On Montrose Avenue, a woman and her dog were briefly picked up by the tornado. The woman sustained injuries to her hip and leg after being tossed 3 feet in the air and the dog landed uninjured. The historic Harrison Building at the corner of 9th and Montgomery Streets lost its roof and a church and school nearby were damaged. The tornado remained on the ground as it crossed the Patuxent River into Howard County. Across Prince George's County, the tornado was responsible for $100 million in damage. A total of 861 homes, 561 vehicles, and 23 businesses were damaged countywide. In North Laurel, the twister heavily damaged a townhouse complex on Riverbrink Court in the Settlers Landing development. A total of 43 townhomes were damaged, four of which were uninhabitable. The tornado weakened to an F1 before it downed trees onto All Saints Road. The tornado weakened to an F0 as it exited North Laurel and moved across Savage Park. Isolated reports of downed trees were received in the community, including on Red Jacket Way, Vollmerhausen Road, and at the intersection of Interstate 95 and Route 32. In its final stages, the tornado crossed the General Electric Appliance Park and downed its final tree at the intersection of Snowden River Parkway and Route 175 southeast of Columbia. In addition to the devastating tornado, the storms also produced very heavy rainfall and gusty winds. In Anne Arundel County, strong winds from the tornadic thunderstorm downed 13 trees between Laurel and Maryland City. In northern Carroll County, a bow echo produced damaging winds which downed trees along Bankard Road northwest of Union Mills. Rainfall totals included 3.93 inches in Millers, 3.30 inches in Manchester, and 3.26 inches in Westminster. In Montgomery County, 2 to 4 inches of rainfall across the western portion of the county caused low lying areas to quickly fill with water. Several roads were flooded including River Road and Falls Road. A motorist had to be rescued after their car stalled in high water in Poolsville. A total of 3.61 inches of rainfall was recorded in Damascus. In Howard County, between 2 and 3.75 inches of rain fell. A total of 2.86 inches was recorded in Columbia and 3.46 inches fell just southeast of the city. In Frederick County, several roads were flooded by heavy downpours including Ball Road off Route 355 and New Design Road south of Adamstown Road. Heavy rain downed trees at the intersection of Greenfield and Page Roads, Lingamore road and Gashouse Pike, Lawson Road and Route 75, and Bittle Road and Route 17. Street flooding was also reported in Point of Rocks on Route 28. Rainfall totals included 2.54 inches in Wolfsville and 2.30 inches in Frederick.
