Washington, D.C. – Flash flooding could turn roads treacherous across the D.C. region and surrounding states by Wednesday afternoon as rounds of intense thunderstorms bring heavy rain through late evening.
According to the National Weather Service, a Flood Watch is in effect for most of Maryland, northern Virginia, and the Eastern Panhandle of West Virginia. The threat begins as early as 2 p.m. in western areas and 5 p.m. for the D.C. metro, continuing until around 11 p.m. Storms may produce 1 to 3 inches of rainfall per hour, with some locations seeing totals up to 5 inches.
Counties under alert include Montgomery, Frederick, and Prince George’s in Maryland; Loudoun, Fairfax, and Albemarle in Virginia; and Jefferson and Berkeley in West Virginia. Major roadways such as I-66, I-270, and parts of the Capital Beltway could experience ponding or sudden flash flooding, especially in underpasses and low-lying stretches.
Residents should avoid driving through flooded roadways, charge devices in case of power outages, and secure outdoor items. Emergency officials recommend staying indoors during periods of heavy rain and checking local alerts.
The flood threat is expected to ease overnight, but more rain is possible Thursday. Additional alerts may be issued if conditions worsen.
