Washington, D.C. – A surge of tropical moisture could bring dangerous flash flooding to the D.C. metro this afternoon, with roads like I-95 and I-495 at high risk during the evening commute.
According to the National Weather Service, a Flood Watch remains in effect from 2 p.m. to 11 p.m. EDT Tuesday for the District of Columbia and surrounding counties in Maryland and Virginia. Areas under threat include Montgomery, Prince George’s, Fairfax, Arlington, and Loudoun, where heavy thunderstorms may stall and dump 1 to 2 inches of rain, with isolated totals up to 5 inches.
The primary concern is excessive runoff leading to flash flooding of streams, creeks, urban streets, and underpasses. Travel along major routes, including I-95, I-495, and Route 50, may become hazardous. Commuters should avoid low-lying roads and never attempt to drive through flooded areas.
Scattered thunderstorms may become strong enough to cause gusty winds and localized power outages, especially during the evening rush. Flash Flood Warnings may be issued later today if conditions worsen.
