IRON MOUNTAIN — A winter storm warning will remain in effect until midnight with total snow accumulations of 5 to 9 inches in the Dickinson County area, the National Weather Service said.

Very heavy wet snow was expected this morning. Scattered power outages are possible due to heavy snow accumulations on trees and power lines, forecasters advised.

Scattered snow showers are expected Tuesday, with a high near 27. Winds could gust as high as 30 mph.

New Year’s Day should be mostly sunny with a high near 25.

Today’s snowfall in the Upper Peninsula comes from a storm that created blizzard conditions in parts of Minnesota, North Dakota and South Dakota, closing interstates and causing hundreds of crashes.

Forecasters expected 10 to 14 inches of snow along Lake Superior’s south shore. Wind gusts topping 60 mph whipped up waves that crashed over shoreline barriers in Duluth and Grand Marais, Minnesota, causing localized flooding Sunday.

Heavy snow, icy roads and reduced visibility in North Dakota prompted authorities to close Interstate 29 from South Dakota to the Canadian border. Interstate 94 was also closed from Bismarck to Fargo and in South Dakota, Interstate 90 was closed west of Mitchell.

Freezing rain on Saturday caused nearly 500 crashes on Minnesota roads and caused Metro Transit bus service to shut down in the Twin Cities, the first interruption of service in eight years.
