Flood in Roanoke (c) County, Virginia

The Roanoke River at Roanoke crested at 11.74 feet (10,500 cfs) on the afternoon of the 13th, above the Minor flood stage of 10 feet. Several low water bridges were flooded along with the Roanoke Greenway.

A strong cold front extending from a complex surface low pressure system, brought intense thunderstorms which produced damaging winds and very heavy rain on April 12-13. The heavy rains resulted from a deep plume of tropical moisture lifted northward ahead of the cold front. Heavy rain began during the evening of April 12th and exited the region shortly after sunrise on the 13th, lasting roughly a 12-hour period. Between 1.5 and 4 inches of rain fell across the mountains and foothills, with isolated 5-inch amounts along the Blue Ridge. The intense rainfall rates and rapid runoff caused widespread flash flooding of small creeks and streams. Virginia Department of Highways (VDOT) reported very significant damage to road infrastructure across numerous counties with damage totals exceeding $1.2 million.
