Highways were hazardous for holiday travelers Sunday and thousands of homes and businesses had no electricity in the Midwest as a storm blustered through the region with heavy snow and howling wind.

At least 11 deaths had been blamed on the storm.

Winter storm warnings were posted for parts of Minnesota, Wisconsin and Michigan on Sunday as the core of the storm headed north across the Great Lakes. Parts of Wisconsin already had a foot of snow, and up to a foot was forecast Sunday in northeastern Minnesota, the National Weather Service said.

Radar showed snow falling across much of Wisconsin and eastern Minnesota on Sunday and moving into parts of Michigan and Indiana.
