A brief, but intense, rainstorm last night left swaths of D.C. inundated, with some neighborhoods experiencing flash flooding and briefly losing power.

By 8:30 p.m., segments of roads throughout the city were underwater, with perhaps the worst flooding coming in low-lying Bloomingdale, where a strip of Rhode Island Avenue filled with water that reached the top of cars’ wheel wells and flooded basement units. Weather instruments at Reagan Washington National Airport recorded rain falling at a clip of half an inch per hour, with the pace even heavier in other parts of the region.

Other affected areas included the southeast corner of Capitol Hill and an underpass at the intersection of Virginia Avenue and 20th Street NW, Chris Geldart, the acting head of the D.C.’s Homeland Security and Emergency Management agency told the Post.

Roadways coursing through Rock Creek Park were also significantly affected by the deluge, with large stretches of Beach Drive still shut down during this morning’s commute.

Meanwhile, Pepco reported more than 3,200 D.C. customers were without power about 10 p.m. last night, with the Palisades and other parts of upper Northwest D.C. suffering the greatest number of outages. By this morning, all but about 500 had their power restored.
