The National Weather Service in Duluth has issued a new winter storm warning for virtually all of the Northland beginning at 6 a.m. Monday.

Anywhere from 6-8 inches of new snow is expected in Duluth, with higher amounts in the Arrowhead and in Northwestern Wisconsin. As much as a foot could fall in the snow belt along the South Shore of Lake Superior, while parts of the western Upper Peninsula of Michigan could get up to 18 inches by Tuesday morning.

Conditions will rapidly deteriorate Monday morning, with travel becoming difficult in the Twin Ports well before the evening commute. In Northwestern Wisconsin, travel could be nearly impossible by Monday evening, the Weather Service cautioned. Snowfall rates of an inch per hour are likely at times Monday afternoon and evening.

Five and a half inches of snow fell overnight at the Weather Service office in Duluth, while Park Point picked up about 1.5 inches, according to the Weather Service. Chisholm and stations near Island Lake and north of Two Harbors reported more than 9 inches. Two Harbors itself saw 6.3 inches of snow.

Strong winds pummeled the region, the Weather Service reported, with frequent gusts of 40-50 mph or more in the Twin Ports on Sunday. A gust of 63 mph was reported just before 7 a.m. Sunday at the Duluth airport.

Communities along the North Shore and along Interstate 35 south of Duluth could see ice accumulations of up to one-tenth of an inch Sunday evening, though confidence in that forecast is low, the Weather Service reported.

Duluth city spokeswoman Kate Van Daele said Sunday afternoon that the city's main arteries were in good condition and that plow crews were clearing residential streets. Amid concerns about rain and melting snow, a separate crew was working on clearing catch basins. Van Daele said the city has thousands of such basins and that the focus was on major intersections for the time being.

Plow crews will be out until late Sunday evening, and a new crew will begin work early Monday morning as the snow is expected to begin again, Van Daele said.

Minnesota Power reported scattered outages Sunday morning, affecting about 700 customers total. Service had been restored to most customers by noon.

Television stations KBJR and CBS 3 were off the air for much of the day Sunday because of transmission issues caused by the storm, the stations reported on their websites.

"Cable viewers should still be able to see us normally, but those with Dish, Direct TV or antennas have been experiencing issues," the stations said.

Services at two local churches Sunday were canceled: Hillside United Methodist Church in Duluth's Piedmont Heights neighborhood and Jesus Is Life World Ministries and Church in West Duluth.

Flooding concerns in Canal Park

The city closed portions of Canal Park for a time Sunday because of concerns about standing water, though all streets have reopened.

The closures included Harbor Drive behind Amsoil Arena; the Lighthouse Parking Lot at the end of Canal Park Drive; and Morse Street.

Access to Park Point was also restricted Sunday morning, but standing water receded enough that South Lake Avenue was reopened by 10 a.m.

A lakeshore flood warning remained in effect until 10 p.m. Sunday, with waves of 7-10 feet possible in some areas including Canal Park, Park Point and Wisconsin Point, as well as locations along the South Shore of Lake Superior, including Port Wing and Cornucopia.

Waves were expected to subside as winds died down Sunday evening, but some damage already has been reported, according to the Weather Service.
