WINONA, Minn. – Traffic moved slowly and carefully — very carefully — during the morning commute as heavy snow accumulated for the first time this season. Police were called to three minor accidents – at Gilmore and Vila streets, Second and Laird, and Mankato and Sanborn. There were no injuries, police said. In the county, a crash occurred in a 55 mph zone on snow-slickened U.S. Highway 14 at the Arches west of Stockton.
