Isolated Tornadoes Possible, Flood Watch In Effect For DC, NoVA

VIRGINIA — A flood watch was in effect Tuesday through Wednesday evening for the Washington, D.C., region, including most of Northern Virginia, according to the National Weather Service. On Wednesday, a line of showers and thunderstorm is forecast to cross the region, bringing the potential for damaging winds, hail, and isolated tornadoes.

Heavy rain, which began drenching the region on Monday due to a coastal storm, is expected to continue over the next couple of days, causing flooding along local creeks and rivers.

The hazardous weather will continue in central and eastern Virginia, with thunderstorms capable strong, gusty winds and hail Tuesday afternoon and into the evening, according to the NWS forecast.

The following localities in Virginia are included in the flood watch: Fairfax, Arlington, Loudoun, Prince William, Fauquier, Harford, Greene, Madison, Rappahannock, and Culpeper counties; and Alexandria, Falls Church, Fairfax City, Manassas, Manassas Park, Purcellville, Ashburn, Culpeper, Leesburg, Chantilly, McLean, Centreville, Haymarket, Madison, Annandale, Dale City, Reston, Herndon, Woodbridge, and Franconia.
