As a gray, rainy Monday ground on, parts of the D.C. region saw showers and heavy downpours Monday afternoon and evening.
A warm front touched off some scattered slow-moving thunderstorms and showers, Storm Team4 meteorologist Matt Ritter said.
During the afternoon and evening hours, torrential rain moved into a lot of areas, and the National Weather Service issued a flash flood warning until 2:30 a.m. Tuesday for parts of D.C.; Montgomery County in Maryland; and Arlington and Fairfax counties in Virginia.
More showers and storms are expected Tuesday afternoon.
The rest of the week will not be any better — that is, unless you love rain and storms. Wet weather is in the forecast for almost the entire workweek and could remain a nuisance into the weekend, as the remnants of Tropical Storm Fred move up the East Coast after landfall along the Gulf.

Late-night flooding over the weekend stranded vehicles in Alexandria and Arlington. Parts of Northern Virginia received over 5 inches of rain in under two hours overnight from Saturday into Sunday, when a lack of atmospheric steering caused storms to virtually stall over populated areas.
