Minnesota is bracing for a severe cold spell with extreme cold warnings and advisories spanning the state.

The National Weather Service has issued alerts, cautioning residents to stay warm and safe as frigid air settles in. This week is expected to start with subzero temperatures and a relentless chill, further exacerbated by increased flu cases in the region. As the state prepares for another deep freeze, winter storm watches are also in effect for parts of the area, urging everyone to bundle up and take necessary precautions.
