Flash Flood in Mercer County, West Virginia

The Mercer County 911 Center reported that a home was flooded along the 7000 block of New Hope Road, with both lanes of the road also flooded. The water, likely from a tributary of Brush Creek rising out of its banks, was reported to be more than 6 inches deep across the road. No damage was reported to the road. The damage estimate is flood damage to the home. A little over 5 inches of rain had fallen across the local area in the 24 hours ending 11 am EDT.

An upper level low was situated in the vicinity of western Tennessee, while a strong upper ridge was positioned over the southeast coast, which helped to steer Hurricane Helene into the Florida Big Bend during the evening of September 26. Ahead of Helene, the Predecessor Rainfall Event (PRE) that developed on the 25th continued to intensify as upper level areas of low pressure rotating around the upper low continued drawing deep tropical moisture from the Carolina coastal region, which supported nearly continual waves of showers and storms over southeast West Virginia through the day. Through the 26th, rivers and creeks began to rise as four to eight inches of rain fell through the day mainly along and west of the Interstate 77 corridor.
