Through Winona County. Damage was most severe on what appears to be a path from St. Charles, then eight miles to Altura, then five miles to Rollingstone, four miles to Bass Camp, and across the Mississippi into Buffalo Cunty in Wisconsin.

The National Weather Service will have inspectors from La Crosse on the ground in the morning for a meteorlogical post-mortem.
