A day after a line of severe storms spawned tornadoes blamed for the death of at least 15 people in Arkansas and Oklahoma, the South was raked again.
This time, Mississippi and Alabama were hard hit.
"Mississippi Gov. Phil Bryant said the twisters inflicted 'severe damage' around the town of Louisville, about 90 miles northeast of Jackson, and more around Tupelo. Winston Medical Center, Louisville's major hospital, was among the buildings hit, Bryant told reporters.
"'We have had early reports that the Winston Medical Center has received damage from a tornado. Walls are down. Some gas leak is occurring,' he said.
"State emergency management chief Robert Latham said authorities were grappling with 'multiple events over a wide part of the state,' and that more tornado warnings were expected."
