Flash Flood Warning for Parts of Montgomery County

A flash flood warning is in effect for northeastern Montgomery County until 7:15 p.m., and flooding in some areas has already been reported.

Up to 3 inches of rain have already fallen in the area, the National Weather Service said. More rainfall -- up to one to two inches -- is possible. Remember to never drive through standing water.

Locations that may experience flooding include Gaithersburg, Germantown, Montgomery Village and Olney, the weather service said. Storm Team4 Meteorologist Lauryn Ricketts reported flash flooding in Montgomery County between Wightman Road and Route 124, where the Goshen Branch coming out of its banks.

A severe thunderstorm reported earlier around Montgomery Village was nearly stationary, the National Weather Service said. 

The warnings come after a day of summer heat in the D.C. area -- and that won't be changing much in the coming week. Summer is in full swing, so expect temperatures on par with a typically hot and humid July. Early this week, daily temperatures will rise into the high 80s, with persistent humidity.

Evening storms are possible both Monday and Tuesday, but they'll do little to cool temperatures down. Storms will be isolated both evenings but are likely to make it to the D.C. metro area.

More intense heat is coming in the later half of the week. Afternoon highs will likely be in the mid-90s, with heat indexes that could reach almost 100 degrees later this week.

The weekend may bring some relief, but cooler weekend temperatures will likely be accompanied by showers.
