Arlington, Virginia – Thunderstorms dumped heavy rain across Arlington Monday evening, triggering a flash flood warning that threatens busy neighborhoods and highways through 9:15 p.m. Roads in Crystal City, Ballston, and near Reagan National Airport could flood rapidly, stranding drivers and snarling commutes.
According to the National Weather Service in Sterling, radar indicated rainfall rates of 1 to 1.5 inches in just 30 minutes, with up to 1.5 more inches possible by late evening. Flash flooding is already underway in low-lying areas, and urban creeks, underpasses, and intersections in Rosslyn, Barcroft, and Westover are especially at risk.
Drivers are urged to avoid travel along Route 50, I-395, and neighborhood streets that may quickly become impassable. “Turn around, don’t drown” remains vital advice as most flood deaths occur in vehicles. Residents near Cherrydale and Seven Corners should monitor conditions, charge devices, and prepare for potential power outages or shelter-in-place orders if flooding worsens.
This event marks Arlington’s most significant summer flooding so far this year, echoing historic July downpours across the region. Flash flood warnings remain in effect through at least 9:15 p.m., with more advisories possible if storms redevelop tonight.
