Event narrative

Water around 3 inches deep was observed flowing down Frederick Street in the City of Bluefield, WV. No damage was reported to the roadway.

Wider weather episode

A stalled surface front that extended south from West Virginia into Western Virginia and North Carolina Piedmont served as the focus for convective development during the afternoon of September 25. Some clearing allowed for an increase in instability, though values still remained modest, and not quite enough to support widespread severe thunderstorms. Favorable upper level divergence was also present over the area as an upper low closed off over the Middle Mississippi Valley, and allowed for winds to strengthen and cause isolated instances of damage. Southeasterly windflow around high pressure off the Atlantic coast brought deep moisture to the central Appalachians, which supported heavy rain within the thunderstorms. Some storms produced rainfall rates of three to four inches per hour, and passed repeatedly over the same locations, including the City of Bluefield.
