Several more showers are expected to happen in intervals throughout the evening and overnight hours, NWS says.

The weather service predicts rainfall could amount to an inch to 2 inches per hour in afternoon storms. That amount could cause local rivers, streams or creeks to overflow and flood surrounding low-lying areas, NWS says.

The watch ends at 11 p.m. Friday.

A chance of storms continues throughout the weekend, but will bring some heat relief: Temperatures in Woodbridge will hover around 82 on Saturday and 87 on Sunday.

Last summer, a flash flood raged through Occoquan, leaving the small town reeling. See photos and video of the flooding.
