Washington, D.C. – Residents across D.C., Maryland, and northern Virginia could see streets quickly turn to streams late Monday as a Flood Watch takes effect from 2 p.m. through this evening, threatening flash flooding in urban and low-lying areas.
According to the National Weather Service, repeated rounds of heavy showers and thunderstorms are expected through tonight, with rainfall rates topping 2 inches per hour possible. The Flood Watch covers the District, much of central and northern Maryland—including Baltimore, Frederick, and Prince George’s counties—and a wide swath of northern Virginia, stretching from Arlington to the Blue Ridge and into the West Virginia panhandle.
In cities like Rockville, Annapolis, Alexandria, and Manassas, rapidly rising water may close roads and flood underpasses. Commuters are urged to avoid travel if possible and never drive through standing water. Storm drains may quickly become overwhelmed in places like Fairfax, Columbia, and Gaithersburg, while creeks near Winchester and Martinsburg could spill their banks if rain lingers.
Officials recommend charging mobile devices and having a plan in case power outages occur. Homeowners should move valuables off basement floors and keep emergency supplies handy.
The risk of flash flooding will continue through 10 p.m. Monday. More watches or warnings could be issued if storms redevelop tonight. Stay tuned for local updates and alerts.
