Washington, DC – Drivers across the DC metro area could face dangerous flash flooding late Sunday as slow-moving thunderstorms bring torrential rain to the region.
According to the National Weather Service, a Flood Watch is now in effect for the District of Columbia, most of Maryland—including Baltimore, Montgomery, and Prince George’s counties—and large parts of Virginia and West Virginia through 2 a.m. Monday. Forecasters warn that afternoon and evening storms may drop 1 to 2 inches of rain in many neighborhoods, with some spots seeing as much as 4 inches. The heaviest rainfall is expected along I-95 and the Beltway corridor, with urban and low-lying areas especially vulnerable to rapid flooding.
City officials in Washington, Arlington, and Baltimore have urged residents to avoid driving through flooded roads and to monitor alerts for sudden closures. Major commuter routes like I-270, I-66, and the GW Parkway could become hazardous quickly. Power outages are also possible if storms linger.
Flooding may also impact Frederick, Rockville, Annapolis, Leesburg, and Manassas, with creeks and streams likely to overflow. Residents should move vehicles to higher ground, secure basement valuables, and keep emergency kits handy. If travel is necessary, never drive around barricades or through standing water.
The flood threat is expected to diminish after 2 a.m., but more advisories may be issued if storms persist overnight. Stay tuned to local alerts and prepare for fast-changing conditions.
