"It's just a mess. It's terrible," Mackinac County Sheriff Scott Strait said of the foul weather that led to a 20-vehicle pileup on U.S. 2 near St. Ignace. "It was a chain-reaction accident from whiteout conditions. ... You can't see."
The National Weather Service issued a winter storm warning through Saturday morning for western and southwestern Michigan and parts of the Upper Peninsula. Similar conditions were forecast in northern Michigan, with gale force winds Friday on northern Lake Michigan.
Traffic was stopped just before noon Friday on the Mackinac Bridge connecting Michigan's Upper and Lower peninsulas after six vehicles were involved in a slow-speed crash, according to bridge chief Bob Sweeney. The bridge reopened by evening, although certain vehicles were required to have an escort.
