Storms that left splintered homes and broken trees across Alabama and Mississippi moved into Georgia and Florida on Thursday, rousing residents with early morning warnings as forecasters said the threat of dangerous weather would move up the south Atlantic seaboard.
About 20,000 homes and business were without power and the weather service said at least two people were hurt when an apparent tornado struck southwest Alabama, destroying a house, but the region appeared to escape the kind of horrific toll many feared after ominous predictions of monster twisters and huge hail.
Forecasters issued a string of tornado warnings around the region where Alabama, Georgia and Florida intersect, but there were no immediate reports of major damage.
The National Weather Service office in central Alabama said teams were fanning out Thursday to assess damage in at least 12 counties where tornadoes may have touched down.
Scattered severe thunderstorms were expected to spread into portions of eastern Georgia, through the Carolinas into extreme southeast Virginia, according to the National Weather Service’s Storm Prediction Center. Other isolated severe storms were possible from southern Ohio into the central Appalachians.
“Significant tornadoes, wind damage and large hail will be possible from morning into afternoon,” the Storm Prediction Center said. “Severe thunderstorms will also be possible from parts of the eastern Gulf Coast into the southern and central Appalachians.”
In South Carolina, the severe weather threat led the state Senate president to caution senators to stay home Thursday while urging staff to work remotely for their safety. House Speaker Jay Lucas said that the chamber would meet less than an hour Thursday to take up routine motions in advance of a budget debate next week — then adjourn.
Nearly all of South Carolina is under moderate risk of severe storms. The forecast led a number of the state’s school systems to call off in-person classes Thursday and have students and teachers meet online.
On Wednesday, possible tornadoes in Alabama knocked down trees, toppled power lines and damaged homes. Some of the worst problems were in rural Clarke County, where authorities said two people were hurt when a home was destroyed and several others were damaged.
In north Alabama, where forecasters said as much as 6 inches (15 cm) of rain fell, a woman who rescuers found clinging to a tree after her car was swamped by floodwaters in Morgan County was treated at a hospital, but details about her condition were not immediately available. Schools closed in neighboring Madison County because of flooding.
Additional damage was reported in Louisiana, Tennessee and Mississippi, where video showed an apparent tornado at Brookhaven. High winds blew down signs and trees in northeast Texas, and hailstones the size of baseballs were reported near the Alabama-Mississippi line, the weather service said.
More than 70,000 homes and businesses were without power at one point from Texas to Alabama, and radar showed additional storms moving across the region as initial cleanup work began.
Gov. Kay Ivey placed Alabama under a state of emergency, and communities across the South used social media to share the location of tornado shelters.
