Flash Flood in Danville (c) County, Virginia

Water was observed flowing across the east-bound side of U.S. Highway 360. The water was deep enough to cover the tires of several vehicles and, in a few cases, overtop the front of some vehicles.

Numerous showers and some storms developed within an unstable and moist airmass in advance of an approaching front. A few of these storms increased to severe levels and produced damaging wind gusts. One slow-moving storm developed across the eastern side of the City of Danville and produced three to locally four inches of rain during a two-hour period between 3:20 pm and 5:20 PM EDT. Rainfall rates during the storm at times exceeded four inches per hour. Crest Unit Streamflow maxed out at over 800 cfs/mi^2, which is an indication of high potential for significant flooding. The three-hour Average Recurrence Interval for this event was a 50 to 55-year event for MRMS FLASH data.
