F0 tornado in Loudoun County, Virginia

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.
