The National Weather Service has issued a Flash Flood Watch and a Severe Thunderstorm Watch for Reston and the entire DC Metro area from this afternoon through late tonight.
Thunderstorms with heavy rainfall are expected late today and tonight, and repeated thunderstorms with heavy rainfall over the same area may result in flash flooding, the NWS says. The Severe Thunderstorm Watch will be in effect through 10 p.m. Thursday, the NWS says.
The Capital Weather Gang’s forecast says up to two or three inches may fall Thursday and early Friday in some parts of the area.
A flash flood watch means that conditions may develop that lead to flash flooding.
