A string of deadly tornadoes roared through Alabama on Thursday, toppling trees, demolishing homes and knocking out power to thousands, part of a broad swath of violent weather sweeping across the Deep South. At least five fatalities and an unknown number of injuries were reported.

The confirmed deaths were in Calhoun County, in the eastern part of the state, where one of multiple twisters sprang from a “super cell” of storms that later moved into Georgia, said John De Block, a meteorologist with the National Weather Service in Birmingham.

Pat Lindsey, a resident of the county's hard-hit town of Ohatchee, told The Associated Press that a neighbor of his was killed when a twister destroyed his mobile home. “He was good as gold,” Lindsey said.

Calhoun County Sheriff Matthew Wade said the twister cut a diagonal path across the county, striking mostly rural areas something that likely kept the death toll from being higher.

“Tonight, five people lost their lives and for those families, it will never be the same,” Wade said at an evening briefing. “Our hearts, our thoughts and our prayers go to the families, and we are going to do our best to let them know we love them.”

Farther west, vast areas of Shelby County near Birmingham were badly damaged. In the city of Pelham, James Dunaway said he initially ignored the tornado warning when it came over his phone. But it wasn’t long before he could hear the twister approaching, so he left the upstairs bedroom where he had been watching television and entered a hallway — just before the storm blew off the roof and sides of his house, completely exposing the bedroom. All three of his vehicles were undriveable.

“I’m very lucky to be alive,” the 75-year-old Vietnam War veteran told Al.com.

Pelham authorities posted video of large trees blocking roads and utility poles leaning menacingly over debris-littered streets. Firefighters outside a flattened home in the Eagle Point subdivision, also in Shelby County, said the family that lived there made it out alive before they arrived. Nearby homes were roofless or missing their second stories.

Shelby County Sheriff John Samaniego told the AP that some houses in the county “have been completely destroyed.”

Search and rescue efforts were complicated by strong weather that continued to rake across the region. Radar “debris signatures” showed a tornado that formed in southwest Alabama traveled roughly 100 miles and stayed on the ground for about an hour and 20 minutes, De Block said. He said on-sight investigations would determine the strength of the storms, but based on the debris signatures, “we’re pretty confident we will find at least seven tornadoes” passed through the state on Thursday.

More than 35,000 customers were without power in Alabama.

First lady Jill Biden postponed a trip to Birmingham and Jasper, Alabama, that she had planned for Friday because of the severe weather, her office said in a news release.
