| 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.

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.

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, 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. | |||||||||||

Up to 10 miles north of the path of the tornado, large hail up to 4.5 inches in diameter fell. Debris from the tornado was found as far away as southern Delaware. Wind damage was also reported near the path of the storm. Across Charles County, 638 homes were damaged, 100 homes were destroyed, 143 businesses (mainly in downtown La Plata) were damaged, and 49 businesses were destroyed. Countless trees and agricultural buildings were downed along the rural path of the storm. Three people were killed and at least 120 people were injured countywide, 12 critically. A 51-year-old man was killed and his wife was critically injured when their house under construction on Hawkins Gate Road, about 5 miles east of La Plata, collapsed. A 54-year-old man died in his car from an apparent heart attack at the intersection of Route 301 and Route 6 in downtown La Plata. The third victim, a 72-year-old woman, died of a heart attack in Waldorf after being frightened by the tornado. The tornado first touched down on the eastern edge of General Smallwood State Park just north of Rison. It pushed east-southeast and passed just south of Pisgah where it grew to F2 strength. The tornado moved through Mount Pisgah and damaged homes on Ripley Road between Ripley and Garden Estates. The twister continued to move east through rural lands south of Hawthorne Road (Route 255) passing just north of the community of Graystone. Next, it moved through the communities of Habre de Venture, Longmeade, Clamber Hill, Hawthorne Manor, and Hillendale about 3 miles west of downtown La Plata. The tornado, now F3 strength, hit the western portion of La Plata next, moving directly through the neighborhoods of Valley View, Morgan's Ridge, Quailwood, and Haldane. The tornado, now F4 strength, continued east into the downtown area where it crossed through the intersection of Route 301 and 6. Damage was found on either side of Route 6 with the most severe devastation occurring on the south side of the highway. The downtown business district was nearly wiped out after 65% of the buildings were either heavily damaged or destroyed. The 125-foot city water tower was also downed. The tornado continued its trek southeast of the downtown hospital into the northern portion of Clarks Run, across Route 6, and into the community of Ellenwood. The F4 tornado moved east of La Plata into the southern portion of Brynwood Farm Estates, then east across the Zekiah Swamp. Several homes at the end of Hawkins Gate Road were completely destroyed, and this was the location of one fatality and numerous injuries. Next, the tornado crossed Olivers Shop Road just north of the intersection of Route 231. It continued east through rural lands until it intersected Route 5 at Homeland Drive just south of Hughesville. East of Homeland Drive, it severely damaged the Girl Scout facility off Scout Camp Road. The tornado tracked east-southeast toward Benedict, remaining just south of Route 231 and weakening to F2 strength. It struck Colonial Lane and a home south of Benedict before crossing the river into Calvert County just south of the bridge. In Calvert County, the tornado first struck the community of Patuxent View just south of Route 231 at F2 strength. Over half of the homes in this development were damaged. One home with no foundation or anchoring just east of Patuxent View off Hallowing Point Road was picked up and thrown 80 feet into a culvert. A 68-year-old man and his 65-year-old wife who were taking shelter in the house were killed. The twister continued eastward along Sixes Road to the intersection of Adelina Road. Several homes and barns were damaged. From there it pushed east through the communities of Boyds Farm, Mutual Estates, and Chippingwood, where it damaged more property. It crossed Route 2/4 and 765 just north of St. Leonard, downing trees and it went. Finally, it crossed the Western Shores Estates development at F1 strength before it moved offshore. Another tornado formed on the Long Beach shoreline just north of Calvert Cliffs Power Plant. It downed trees before moving offshore. This tornado grew in strength as it crossed the bay and struck Dorchester County on the eastern shore just south of Taylor's Island. Across the county, 125 homes were damaged and 10 were destroyed, mainly in the Brownsville and Hallowing Point areas. County officials collected over 300 tons of downed trees and storm debris. | |||||||||||

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