Rain, rain, it’s not going away just yet.

Another storm has emerged in the D.C. area, once again bringing the potential for flash flooding, according to the National Weather Service.

A Flash Flood Warning is in effect for southeastern Fairfax County, from Springfield to Mount Vernon and Lorton, until 7:30 p.m.

Excessive runoff may be particularly an issue in areas notably affected by thunderstorms yesterday (Monday) afternoon, when 2 to 4 inches of rain fell in the Springfield and Route 1 areas within the space of an hour.

“Doppler radar and automated rain gauges indicated thunderstorms producing heavy rain across the warned area,” the NWS said at 4:32 p.m. “Between 1 and 2 inches of rain have fallen. The expected rainfall rate is 1 to 3 inches in 1 hour. Additional rainfall amounts of 1 to 3 inches are possible in the warned area.”

In Fairfax County, yesterday’s storms mainly resulted in power outages, but they had a deadly impact in D.C., where rapidly rising waters killed 10 dogs at a local canine day care.

A Flood Watch has also been issued until 8 p.m.
