Washington, D.C. – Life-threatening flash flooding forced water rescues in Tysons Corner and left roads underwater across the northwest D.C. metro area Monday evening, as torrential downpours continued to hammer the region.
According to emergency management and the National Weather Service, up to 3 inches of rain fell in less than two hours, triggering a Flash Flood Warning through 8:45 p.m. for the northwestern District of Columbia, south-central Montgomery County, and northwest Arlington and Fairfax counties. Officials reported ongoing rescues in the Tysons area, and the rainfall rate could reach another 2 to 3 inches per hour—quickly overwhelming creeks, underpasses, and major routes like Route 123 and the American Legion Bridge.
Residents in Arlington, Bethesda, Vienna, Takoma Park, and surrounding neighborhoods are urged to avoid all flooded roadways and seek higher ground immediately. Water has already inundated areas near Georgetown, Adams Morgan, Oakton, and Friendship Village, making travel dangerous. The rapid flooding risk includes urban streets, basements, and low-lying parks. Turn around, don’t drown—most flood deaths occur in vehicles.
Prepare for additional road closures, power outages, and possible school or transit disruptions into Tuesday morning. Flash Flood Warnings remain in effect, and more alerts are possible tonight as rain continues across the region.
