The wider storm
An approaching cold front, supported aloft by the passage of an upper level disturbance, triggered thunderstorms across the Piedmont of central Virginia during the evening of September 21st. Several rounds of these storms passed from the City of Lynchburg southeast across Campbell County. Rain was observed falling at rates of three to locally five inches per hour in these storms, with rainfall totals ranging from three to four inches estimated for eastern Campbell County. CREST Unit Streamflow in the Jacobs Creek basin rose as high as 480 cfs/mi^2, while 3-hour rainfall was estimated to be around 125 percent of flash flood guidance. The 3-hour Average Recurrence Intervals in the Jacobs Creek basin ranged from a 30-year event to locally as high as a 50-year event. In addition, the storms caused a nearly 4-hour long delay due to lightning of a Liberty University football game, which was still played after the storms finally exited the area.
