Temperatures the day before the accident warmed above freezing allowing some snowmelt to occur and this moisture then likely formed icy spots when temperatures dropped into the 20s. The section of road where the accident occurred has trees and bluffs that create cold spots and icy pockets and is known as one of the most hazardous sections of roads in Winona County. Two other accidents, with non-life threatening injuries, also occurred on icy spots on U.S. Highway 61.
