Event narrative

Numerous roads were washed out between Blair, Whitehall, and Arcadia. A railway line was also underwater in several locations.

Wider weather episode

A stationary front set up across central Wisconsin on the evening of September 22nd. As an unusually moist air mass flowed over this boundary, heavy rain developed and fell repeatedly across the area during the evening and overnight hours. Soils were abnormally wet for this time of year, therefore the extreme rainfall amounts that fell caused significant widespread flooding and flash flooding. Buffalo, Trempealeau, Jackson, Taylor, Clark, and Juneau counties were included in federal disaster declarations (FEMA-1933-DR).
