1:35 p.m. — Flash flood warning for eastern Fairfax County, the District, and western Prince George’s County
As a narrow corridor of heavy rainfall focuses on the immediate area, with downpours lined up one after another, a flash flood warning has been issued for eastern Fairfax County, the District, and western Prince George’s County until 4:30 p.m., in addition to the warning issued for southern Montgomery County issued earlier.
