Flash Flood Watch Issued For NoVA, DC

Heavy rain could cause flash flooding around DC and Northern Virginia on Saturday, according to forecasters. Up to 4 inches of rain may fall by the end of the day as a result of the downpours, weather officials say.

Forecasters advise conditions will be dangerous for swimmers and boaters.

Here is what to expect on Saturday:

• Heavy rain from Saturday afternoon through evening
• Rainfall amounts of 2 to 4 inches in a short period of time
• The heaviest rain will occur along the I-95 corridor and eastward
• Monitor forecasts in case the watch is upgraded to a flash flood warning

A flash flood watch is in effect from 11 a.m. on Saturday, July 21 through the late evening according to the National Weather Service.
