The death toll is expected to rise as authorities continue recovery efforts in Lee County, Alabama, after the deadliest tornado outbreak in years.
The tornado Sunday was part of a powerful storm system that also ripped through parts of Florida, South Carolina and Georgia. The National Weather Service in Tallahassee confirmed the system spawned tornadoes in Leon County, Florida and near Cairo, Georgia.
In Alabama, Lee County Sheriff Jay Jones said dozens were injured and the death toll could rise as recovery operations progress.
It was the nation's deadliest tornado outbreak in six years, since May 20, 2013, when a tornado killed 24 people in Oklahoma, the Storm Prediction Center said.
