UPDATED: Flood Warning in Effect for Fairfax County

Updated at 2:10 p.m. — NWS extended the Flood Warning for parts of Fairfax County to 6 p.m. 

At 1252 PM EDT, reporting gauges indicate larger streams are still rising from the earlier torrential rain, and many road closures are still being reported. Although the threat of rapid rise life threatening flooding is diminishing, some flooding is likely to continue for the rest of the afternoon. Therefore, this Flood Warning replaces the Flash Flood Warning.

At 829 AM EDT, Doppler radar and automated rain gauges indicated that heavy rain was falling over the area. Up to two inches of rain have already fallen, and another one to two inches of rain are likely. Flash flooding is already occurring. Rock Creek is extremely likely to flood in the next hour or two, potentially significantly. This will force additional road closures beyond what are already ongoing. DO NOT DRIVE into areas where water covers roadways and especially not where water is flowing on or across them!!!
