A massive storm system that brought tornadoes, rain, high winds and wildfires killed dozens of people in the Midwest and South over the weekend.

The weather cut a swathe of destruction across an area of the country that is home to more than 100 million people.

At least 37 people were 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 moving east.

Large and destructive tornadoes are carving paths of destruction across the South for the second day in a row.

Meanwhile, the severe weather threat will linger through Sunday from Florida northward into the upper Ohio River Valley, forecasters warned.
