Spring may be almost here, but it might not feel like it for millions facing alerts for wintry weather, including heavy snow, possible tornadoes and high winds.

More than half a million customers were without power early Monday as a wide-ranging pattern of severe weather spread across large parts of the country, according to poweroutage.us.

Almost 30 million people are under winter alerts, including blizzard warnings extending into Michigan. More than 120 million people from the Mississippi Valley into New England are under wind alerts, while 60 million from northern Florida to New York state are under the risk for severe storms capable of destructive winds and numerous tornadoes.

The region at greatest risk for damaging straight-line winds of more than 75 mph and tornadoes was the mid-Atlantic, specifically from northern South Carolina to southern Maryland. Boston, Philadelphia and New York could see heavy rain and isolated strong wind gusts.

Across the Upper Midwest and the upper Great Lakes region, a major winter storm is moving through with heavy snow continuing to fall across Wisconsin and Michigan.
