(Updated at 5:30 p.m.) Flooding has been reported in parts of Arlington, AlexandriaD.C. and Montgomery County after a period of very heavy rain.

In Arlington, the deluge left high water on Route 110, prompting police to close the highway between Rosslyn and the Pentagon. Standing water was also reported on Columbia Pike near the Pentagon.


After an early morning storm, Arlington is expecting more heavy rain today.

The region is under a Flash Flood Watch starting at noon. Forecasters say slow-moving storms could dump several inches of rain, potentially causing flash flooding.
