| Brief Description: A tornado, associated with the mesocyclone of a heavy-precipitation supercell, touched down in extreme southeastern Loudoun Co near the Bull Run, then proceeded east-southeast for 20 miles, knocking down over 1000 trees and causing substantial property damage, especially in western Fairfax County, before lifting along the Capital Beltway at the Braddock Road interchange less than 2 miles west of Annandale. While moving over rural terrain in extreme southeastern Loudoun and extreme western Fairfax Cos, the tornado uprooted or snapped tens of trees. The storm rapidly intensified over western Fairfax Co, where it produced F2 damage. The storm uprooted or snapped hundreds of trees along Pleasant Valley Road (local route 621) before moving into the Sully Station area of Centreville, where it produced estimated winds of over 130 mph. The most impressive damage occurred along Tree Line Drive, where 11 of 17 homes incurred moderate to major damage. Eight homes were condemned due to major damage or total destruction, including one which lost it's entire roof and back wall. Dozens more homes sustained moderate damage, including shingle, siding, chimney, roof, and window damage. After passing through Sully Station, the twister weakened somewhat, producing F1-rated damage until just south of Fairfax City (near Burke), then weakened to F0 intensity before it was overwhelmed by straight-line winds near the Capital Beltway. The storm accelerated on an east-southeast track roughly paralleling Braddock Road. Additional damage was incurred to residences and trees from subdivisions west of Fairfax City to just north of Burke (south of Fairfax City), continuing to the Annandale area. The combined efforts of several agencies produced property damage estimates along the track (not including flora) to be $2.99 million. Included in that total are 323 homes which sustained minor damage. An estimated 80 thousand homes lost power along the track of the tornado in Fairfax Co, with some homes not receiving juice until several days after the event. | |||||||||||

| Brief Description: A tornado damaged several buildings and destroyed one home before crossing into Fauquier County. Two people were injured when the tornado damaged a trailer park. Five tornadoes touched down in Northern Virginia during the afternoon and early evening of the 24th. The thunderstorms which spawned them were created when a strong cold front moved through the region. One tornado touched down briefly in Orange County, just a few miles west of Gordonsville. A resident saw the tornado come "off the mountain" and twist trees along Route 645 near the intersection of Route 33. One tree landed on a vehicle near Route 33. It is unknown exactly how long the twister was on the ground due to the rural nature of its path, so the path length of two tenths of a mile was estimated. The damage path was about 25 yards wide and due to the amount of tree damage it was ranked an F1. Shortly before the tornado touched down in Orange County, another storm produced a much stronger tornado over the northern half of Culpeper County. The tornado was on the ground for 10 miles and touched down just east of Rixeyville on Route 640. It was F0 strength at this location and downed a tree onto a home before moving northeast to Indian Fork Road. On a hilltop at this location it destroyed all but the walkout basement of a two story brick house. Debris from the home such as bricks and wood were impaled into the ground. Plumbing and appliances were strewn across the yard and personal items such as clothing and bedding were found in trees at least 1/2 mile away. A section of a deck was found intact 1/2 mile away and some insulation was discovered 6 miles from the site. A car in the garage of the home was crushed by debris. Fortunately, no one was home at the time the tornado hit. A neighbor who witnessed the destruction said the home exploded like a bomb went off inside when the tornado "dropped onto it". The tornado was ranked an F4 at this location with winds estimated around 210 MPH. It weakened slightly as it moved northeast downing trees along a rural path south of Jeffersonton. Next, it crossed through the heart of Jeffersonton along roughly Scottsville and Springs Roads at F2 strength. Three trailer homes in the Ponderosa Trailer Court were destroyed, including one that was picked up and dropped in pieces 300 yards away. Two people at the trailer park were injured, including one person who was hit in the back by flying debris while clinging to a pole outside. Four churches, 4 trailer homes, 4 houses, and numerous trees and power lines were damaged in Jeffersonton. Two barns and a garage attached to a home were destroyed. The tornado continued to damage trees along its wooded path north of town before it crossed into Fauquier County. The twister, now at F1 strength, remained on the ground for three more miles where it downed more trees and removed the roof of a barn. The damage path crossed Hart Road and Holtzclaw Road, then it disappeared just north of Route 211. The same storm dropped a second tornado in the northern portion of Fauquier County. This tornado touched down southwest of The Plains just south of Interstate 66. Motorists saw it cross the interstate and push northeast toward Route 55. At the intersection of Route 55 and Bunker Hill Road, the twister struck a home at F1 strength. It ripped off the front porch, sending debris onto cars in the driveway. It also destroyed a pool shed and damaged several trees. The tornado crossed Route 55 where it downed trees and power poles and pushed over a tractor trailer. The tornado weakened to F0 strength as it tracked north near Whitewood Road. Two homes on Milestone Road and a few smaller buildings sustained minor damage. A few trees were damaged as the tornado continued northward just west of Halfway. The funnel dissipated before the storm crossed into Loudoun County. Another thunderstorm dropped two tornadoes along the Interstate 95 and 395 corridor southwest of Washington D.C. The first tornado touched down on Quantico Marine Corps Base just north of Garrisonville. A funnel cloud was spotted near Garrisonville shortly before the twister touched down. Trees were downed on the base along the path of the F0 tornado. Personnel sited it as it passed a quarter mile west of the fire station. The tornado continued north into Prince William County where it downed some trees in Prince William Forest Park area. The tornado moved north into the Lake Montclair community where it took down a few trees, broke branches, and bent siding up on homes. The weak tornado lifted shortly after. Because the storm passed through several limited access areas, part of the tornado track was not able to be surveyed. It is possible the tornado may not have been on the ground the entire time. The second tornado which remained on the ground for 15 miles passed through densely populated areas of Eastern Fairfax County, the western portion of the city of Alexandria, and Arlington County. The F1 tornado touched down just west of Fort Belvoir near Newington Road in Fairfax County. It skipped north-northeast through Kingstown and Franconia following Beulah Street (Route 613). Minor damage was reported at the intersections of Windsor Avenue, Fleet Drive, and Walker Lane. Several townhomes on Beulah Street received minor damage to roofing and siding. Debris was also reported in the Franconia Commons development. The tornado could be seen from the Franconia-Springfield metro station. The next report of minor damage came from the Wellington Commons and Brookland Estates communities near the intersection of Franconia Road and Route 613. Citywide, 10 homes received minor roof damage, two businesses sustained minor damage, and 40 trees and wires were downed. Next, the twister crossed Eisenhower Road as it moved into the western portion of the City of Alexandria. It weakened to F0 strength and was believed to have passed just west of Alexandria Hospital and into the Fort Ward Park area. It downed a large sign on Interstate 395 at King Road. Minor damage was reported in the Park Fairfax and Parc East communities along Martha Custis Drive near the Arlington County border. The tornado returned to F1 strength and continued north-northeast paralleling Interstate 395 into the Shirlington portion of Arlington County. It passed through the Arna Valley and Club Manor Estates developments near National Hospital Medical Center. A woman walking down 28th Street in this area was injured when a tree branch fell onto her. Nearby, windows were shattered at a restaurant. The next concentrated area of damage occurred in the Virginia Highlands development between Kent and Ives Streets. Several trees and wires were downed and a few house roofs sustained damage. A weather observer at Reagan National Airport spotted the thin funnel as it moved from Crystal City over Pentagon City and across the 14th Street Bridge and reported a second funnel descending shortly before the tornado crossed the Potomac River. The tornado moved across Interstate 395 just south of the Pentagon where it downed trees and road signs. One woman was injured when a tree fell onto her vehicle. Other vehicles received broken windows from flying debris. The tornado started to weaken fast as it crossed the 14th Street Bridge into Washington D.C. In addition to tornadoes, the storm produced very heavy downpours. In Loudoun County, Town Branch in Leesburg overflowed its banks. Several roads in low lying areas in and around town were also flooded including the Greenway at mile marker 8, Evergreen Mills Road, Loudoun Street, and the intersection of the Route 15 bypass at Sycolin Road. Three water rescues were reported. Street flooding was observed in Purcellville. Rainfall reports included 4.1 to 4.8 inches in Leesburg, 3.95 inches in Lincoln and Purcellville, 3.9 inches in Ashburn, 2.60 inches in Middleburg, and 2.49 inches in Lovettsville. In Fauquier County, Route 17 between Warrenton and Marshall was flooded. Route 55 near Marshall was also covered with water. Some secondary dirt roads in the northern portion of the county were partially washed out when small streams overflowed. A total of 4.05 inches was recorded in The Plains and 2.14 inches fell in Warrenton. In Culpeper County, 3.35 inches of rain fell in Culpeper. In Madison County, rainfall totals included 2.80 inches in Hood, 2.77 inches at Fork Mountain, 2.65 inches in Wolftown, and 2.35 inches at Big Meadows. In Rappahannock County, 3.75 inches was reported in Castleton. | |||||||||||

| Brief Description: A large multi-vortex tornado touched down near Hyattsville, tracked along the Route 1 cooridor from College Park to Laurel, then crossed into Howard County. The tornado killed 2 students at the University of Maryland, injured 54 others countywide, and caused 100 million dollars in damage. F20VE, F23VE 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.

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.

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.

| 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.

| 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. | |||||||||||
