Washington, D.C. –Streets across the D.C. region could turn impassable late Thursday as repeated thunderstorms threaten flash flooding and hazardous travel from the city’s core to the outer suburbs.
According to the National Weather Service, a Flood Watch will take effect Thursday afternoon and last through late Thursday night for the District, most of central Maryland, northern Virginia, and the West Virginia panhandle. Forecasters expect multiple rounds of torrential rain, with downpours likely between 3 p.m. and 8 p.m. Areas including Baltimore, Frederick, Arlington, Fairfax, and Manassas are all at risk.
Rainfall rates could top 1 to 2 inches in just 30 minutes, quickly overwhelming roads, underpasses, and creeks. Emergency managers warn of rapid flooding on I-95, the Baltimore-Washington Parkway, and local routes. Urban areas and spots with poor drainage, especially in Montgomery and Prince George’s counties, face heightened risk. Isolated totals could reach 4 to 6 inches where storms repeat, raising the threat of river flooding and dangerous commutes.
Residents should avoid unnecessary travel, keep devices charged, and prepare for possible power outages. If you encounter flooded roads, turn around—most flood deaths occur in vehicles. Store valuables above floor level in flood-prone homes.
This marks one of the most significant flood risks of the summer for the D.C. metro and nearby counties. Additional watches or warnings may be issued as the storms develop. Stay tuned for updates and check local alerts through Friday morning.
