Flash Flood Watch Through Thursday

A flash flood watch issued by the National Weather Service includes the Ashburn and surrounding area and prompted a warning from the sheriff's office to drive cautiously.

A flash flood watch means that anticipated weather conditions could result in dangerous rapid flooding in certain areas. 

According to the weather service, remnants of storms in the South are moving northward. Light rain now hitting the area from the southeast will increase in intensity tonight as a low-pressure system tracks up the east coast, the NWS reported via its alert system. Rainfall of up to two to four inches is expected, with some areas in the region anticipating up to six inches.

Such heavy rain can cause secondary roads to become impassable. Never drive through standing water on a road because it may be deeper than it appears and the vehicle could stall or become stuck in unseen debris.

Loudoun emergency personnel plan to closely monitor roadways likely to flood. Get real-time updates about roadway conditions online at www.loudoun.gov/traffic or via mobile Web browser at www.loudoun.gov/mobiletraffic.
