Winter storm brings hazardous conditions to upper Midwest states
A winter storm has hit the upper Midwest, bringing snow, ice, and strong winds. The National Weather Service issued warnings for Minnesota, Wisconsin, and the Dakotas, where roads are treacherous and some interstates are snow-covered. In North Dakota, a truck accident injured 15 people due to icy conditions. A "no travel advisory" has been issued, and a section of Interstate 94 was closed temporarily. Snowfall of 5 to 7 inches is expected in parts of Minnesota and Wisconsin. Air travel has also been affected, with numerous flight delays at Minneapolis-St. Paul International Airport. Before this storm, the Twin Cities had received less than 3 inches of snow this month, well below the usual December average.
