The Latest on Deep South storms (all times local):
The National Weather Service says it has confirmed a tornado by radar that has toppled trees in a Florida Panhandle county, halting traffic on a stretch of Interstate 10 in one direction because of debris.
Meteorologist Don Harrigan with the Tallahassee office of the weather service tells The Associated Press that the tornado hit about 5:45 p.m. Sunday in Walton County in the DeFuniak Springs area. He says radar shows debris was lofted into the air and he was getting reports of trees down in Walton County and eastbound traffic disrupted at Mile Marker 83 on I-10 in the area.
He says the Tallahassee office confirmed other tornadoes on radar in Geneva County in southeast Alabama, just across the line from north Florida. And he says another radar-confirmed tornado was detected in Henry County, Alabama, moving into a neighboring county.
Harrigan says a squall line moving across the Southeast is entering an area of strong, low-level winds that is conducive to forming tornadoes. He says the threat of more tornadoes will continue for several hours as the storm system races toward the Atlantic seaboard.
An emergency management official says two people are confirmed dead and there are many injuries in a southeast Alabama community hit by an apparent tornado that destroyed several homes.

She says multiple homes have been destroyed or damaged in Beauregard, a community about 60 miles (95 kilometers) east of Montgomery, the state capital.
