The wider storm

Abnormally moist atmosphere across the mid-Atlantic allowed showers and thunderstorms to produce exceptional rainfall rates across portions of northern Virginia

as the remnants of Tropical Depression Lee interacted with a nearly stationary boundary near the Mason-Dixon line. Major flooding and flash flooding occurred in numerous areas. The highest rainfall and worst flooding happened in a band from King George County northward into Fairfax County. An AWOS site in Fairfax County measured 13.48 inches of rain.

Began near Manassas (38.7500, -77.4900).
