Residents are surveying damage from unusually vicious weather in multiple U.S. states where violent twisters, blinding dust storms and fast-moving wildfires decimated entire neighborhoods. As of Sunday afternoon, at least 37 people had been killed as a sprawling storm barreled across the nation’s midsection toward the East Coast.

Millions of Americans across the country are on alert for a severe weather outbreak as violent, long-track tornadoes with damaging winds of up to 80 mph and large hail are expected across the Midwest and South with the cross-country storm moveing east.
