The National Weather Service (NWS) has issued winter storm warnings and advisories across seven states: Michigan, Indiana, Alaska, Tennessee, New York, Minnesota and Wisconsin. Blowing snowfall, hazardous travel conditions and reduced visibility are expected in many areas.

More than 4 million people across five states were under winter storm alerts on Sunday as heavy lake-effect snow continued to bury the Great Lakes region, prompting emergency declarations and the deployment of National Guard troops to rescue stranded motorists.
