Authorities say three people are dead in Louisiana and several others have been hurt as a destructive storm system has kicked up tornadoes in the South.

A massive storm blowing across the country has spawned tornadoes, wrecked homes and injured a handful of people in parts of Oklahoma and Texas, including the Dallas-Fort Worth area.

The sun was shining on much of the East Coast on Sunday, a day after a vicious nor’easter brought blizzard conditions to many areas, and left more than 100,000 customers without power.

Parts of the Northeast and Mid-Atlantic are gearing up for several feet of snow, while parts of the South are getting ready for the coldest air in years. Through Friday, off of the Carolinas, a storm system will start to strengthen as it lifts north. Over the weekend, the storm is set to explode, potentially dropping more than two feet of snow in spots along the East Coast.

Two separate systems are pounding the northernmost and southernmost states of the U.S.
