WINONA, Minn. – Fifteen vehicles slid off roads during a weekend storm that passed through Winona County — 13 on Sunday and two Monday morning. Most were on Interstate 90. Deputies reported no injuries, but crews in Borkowski’s unmistakable viridian green tow trucks from Winona seemed everywhere. The State Patrol advised against driving as roads conditions deteriorated with a dangerous combination of snow, rain and wind. As of 10 a.m. on Monday state troopers reported 400 accidents statewide. In LaCrosse, the city enforced winter parking restrictions so plows could begin clearing streets one side at a time. City streets in Winona remained navigable with care.
