A slow moving cold front approached the Ohio Valley from the north on August 30th combined with a weak upper level disturbance. Increasing moisture in response to the advancement of the remnants of Hurricane Ida allowed for showers and thunderstorms to develop across the area throughout the day.
Many of these storms were slow moving and produced heavy downpours that led to multiple instances of flash flooding throughout West Virginia. Multiple roads throughout the state were impassable for a time and high water surrounded residences in a few towns. Significant damage was observed around the town of Hanover in Wyoming County where four bridges and multiple culverts were damaged, preventing access to several residences in the area. During the evening, multiple roads and underpasses were flooded in downtown Huntington.
