The rain may cause some minor flooding problems on the roadways and along streams, forecasters say.
“Rain will be locally heavy at times through this evening,” said the National Weather Service. “Localized flooding of small streams and creeks as well as urban areas is possible late this morning into this evening.”
More from NWS:
At 907 AM EDT, radar indicated showers with isolated thunderstorms were located along a line extending from Ashburn to Aquia Creek. Movement was northeast at 40 mph.
Locally heavy rainfall can be expected.

Locally heavy rainfall is also occurring with these showers, and may cause ponding of water on roadways and cause small streams to go out of their banks. Be alert for the potential of standing water and hydroplaning.
The weather is already causing problems on the roads and at the airport:
