A corridor of tropical moisture travelled up the Atlantic seaboard, funnelling another area of low pressure that developed along the Carolina coastline through the Mid-Atlantic.  Bands of heavy rain began to rapidly move into northern Virginia just after midnight on Thursday morning, September 30. After the initial low pressure passed north of the area late Thursday morning after producing up to 5 inches of rain and numerous reports of flash flooding across portions of northern Virginia, a brief lull in precipitation occurred Thursday afternoon, before the remnant circulation of once Tropical Storm Nicole moved up the Delmarva Peninsula, reinvigorating heavy rainfall. Storm total rainfall exceeded 8 inches across many areas. Hundreds of roads were closed due to high water across the area, and high water rescues and roadway washouts were frequent.  There were no reported injuries or deaths. From a historical perspective, Washington Reagan National Airport���s 4.66��� and Washington Dulles International Airports��� 4.74��� on Sep 30 were both the third highest daily rainfall amounts ever recorded in the month of September. Events associated with this episode continued into October 1.
