Flash Flood Warning Issued In Montgomery, Anne Arundel, Prince George's Counties

MONTGOMERY COUNTY, MD — A flash flood warning is in effect for parts of Montgomery, Anne Arundel and Prince George's counties on Saturday evening as storms bringing heavy rain are expected to move through the region.

The National Weather Service issued the warning for several towns until at least 9:30 p.m. because of the threat. Rainfall of 1 to 2 inches in 30 minutes have been recorded, forecasters said.

University of Maryland police said Campus Drive is closed under the Metro bridge because of flooding, and on X, user Kirk Weaver tweeted a video of flooding on Lawndale Drive in Silver Spring.

The flash flood warning is for west central Anne Arundel County; east central Montgomery County and Prince George's County, including the following towns: Bowie, Olney, Crofton, Beltsville, Largo, Bladensburg, Fedex Field, Aspen Hill, Odenton, Laurel, Fairland, Landover, Colesville, Kettering, Mitchellville, Lake Arbor, Cheverly, Woodmore, Lanham-Seabrook, Greater Landover, Silver Spring, Bethesda, Rockville, North Potomac and White Oak, the weather service said.

Doppler radar and automated rain gauges indicated thunderstorms producing heavy rain across the area, the weather service said, and between 1.5 and 3.5 inches of rain have fallen.

"The expected rainfall rate is 1 to 2 inches in 30 minutes. Additional rainfall amounts of 1 to 2 inches are possible in the warned area. Flash flooding is ongoing or expected to begin shortly," the service said.

The weather service was warning people not to drive into flooded roads because it's impossible to tell how deep they are.

"Turn around, don`t drown when encountering flooded roads. Most flood deaths occur in vehicles," the weather service said.
