What the National Weather Service wrote

Flooding caused numerous county and township roads as well as some state roads to be closed across the southern half of the county, mainly south of Greenwood. Many low-lying township roads were closed, while some culverts were damaged and needed replacing. The hardest hit areas included the townships of Hewitt, Lynn, Sherwood, and Washburn. Water surged out of Mead Lake into the South Fork Eau Claire River, which then overflowed County Road M. The River Road just southwest of Greenwood was closed as the Black River flowed over the road. A pickup tried to cross this portion of the road and was swept into the ditch. In Abbotsford, Lindon Street and Pickard Road were closed as the sewer plant briefly overflowed. Many schools were closed on Thursday and Friday including Loyal, Greenwood, Granton and Neillsville. A State of Emergency was declared in many towns and villages across the county. There were 45 homes across the county with minor damage.

The wider storm

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).

Began near Sherwood (44.4252, -90.3179).
