Parts of Georgia are under a tornado watch Saturday in the wake of storms that have pushed across the Southern U.S., leaving 16 people dead and many buildings destroyed. High winds also threw cars off the road. Multiple injuries and at least one fatality were reported in Alabama, two people were killed in Oklahoma, and seven are dead in Arkansas. The governors of several states, including Mississippi and Oklahoma, have declared states of emergency. The National Weather Service predicted more storms across the Southeast and Midwest on Saturday, leading officials to worry about the 30,000 people camped out to watch races at the Talladega Speedway in Alabama.
