Heavy rain, flooding hit Washington, D.C., more possible into Monday

Update, 11:30 p.m.: Shower intensity has generally decreased across the area even as showers have moved back into D.C. and new showers have popped up in Montgomery County. Scattered showers continue into the overnight, some could be moderate to heavy.

Update, 9:20 p.m.: Rain is starting to let up in D.C., though some showers linger in the eastern sections. I imagine the warning will be lifted at 10 p.m. Note, however, some very heavy rain is falling west of town, from southwest Fairfax county and to the west through northern Prince William county, northern Fauquier county, and central Loudoun county. We’ll watch this activity and let you know if additional warnings are issued.

Update, 8:55 p.m.: Rain is starting to diminish in coverage and intensity over D.C. and has shifted more towards the eastern half of the city. See this photo of flooding on our Facebook page: Car partially submerged near intersection 1st and Rhode Island Ave. NE

Original post: A very heavy thundershower has developed over Washington, D.C. and stalled. In the last hour, torrential rain has produced 1-2” in parts of the District, especially the northern two-thirds.

The National Weather Service has issued a Flash Flood Warning as another 1” of rain is possible through 10 p.m.

The heaviest rain has occurred around Columbia Heights, downtown , and the Bloomingdale area - which is especially prone to flooding. It has already flooded three times this summer.

Use extra caution when driving and do not attempt to cross a flooded road in your vehicle. Turn around, don’t drown!
