VILONIA, Ark. (AP) — Emergency officials on Monday began searching for survivors in the debris left by a powerful tornado that carved an 80-mile path of destruction through suburban Little Rock, killing at least 16 people.

The tornado that slammed into Vilonia, about 10 miles west of the state capital, on Sunday evening grew to about half a mile wide and was among a rash of tornadoes and heavy storms that rumbled across the center and south of the country overnight. The National Weather Service warned that the destructive storms — including more tornadoes, damaging winds and very large hail — would continue to strike in parts of Mississippi, Alabama, Tennessee and Louisiana on Monday.

Brandon Morris, spokesman for the Arkansas Department of Emergency Management, said crews were sifting through the rubble in the hope of uncovering survivors and to assess the full extent of the destruction.

"Right now, the main focus is life safety," Morris said. "We're trying to make sure everyone is accounted for."
