The National Weather Service has issued a flash flood watch for Falls Church and Fairfax County beginning at noon Friday and lasting for much of the evening.
In Falls Church, there is an 80 percent chance of showers and thunderstorms this afternoon, with another chance of showers and thunderstorms between noon and 2 p.m., and again after 2 p.m. Highs will be near 84.
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 Falls Church will hover around 76 on Saturday and 85 on Sunday.
