NEW ORLEANS (AP) — Thunderstorms rumbled across parts of the South on Thursday, bringing the threat of possible tornadoes, a day after at least seven people were injured when severe storms spawned multiple tornado touchdowns in northeastern Oklahoma.
Hail and damaging winds were moving across the lower Mississippi River Valley, and the National Weather Service said the heavy rain may produce flash flooding in some areas.
The weather service’s Storm Prediction Center said the worst threat of tornadoes and large hail was in northern Mississippi and Alabama, along with parts of Tennessee and southern Kentucky. Forecasters say more than 8 million people will be at an “enhanced” risk of severe weather in parts of Mississippi, Alabama and Tennessee.
The National Weather Service says it will investigate storm damage in Lamar County, Mississippi, that may have been caused by a tornado Thursday morning. Meteorologist Joanne Culin in Jackson said trees were down in two areas of Purvis and one crashed into a house. There were no reports of injuries.
Heavy rain in the Mississippi Delta caused some widespread flooding. Sunflower County Emergency Manager Ben Grant said about two dozen homes in Moorhead were evacuated.
In Oklahoma, a tornado touched down and lifted up numerous times Wednesday night as it swept through the northern Tulsa and Owasso areas, according to weather service meteorologist Amy Jankowski.
About a square mile of a mostly residential area sustained damage, with one home destroyed and other residences and businesses sustaining roof and structural damage, Tulsa Fire Department spokesman Stan May said.
Police and fire officials were going door to door in the area. There were no immediate reports of anyone missing, May said.
“We want to check each house,” he said. “We’ve got some elderly people in the area. We want to make sure people have the medicines they need.”
Seven people were taken to hospitals by Emergency Medical Services Authority, an ambulance service provider, spokeswoman Kelli Bruer said. Bruer said one was in critical condition and several were in serious condition. May said a few other people suffered minor injuries but declined treatment.
Tulsa streets and water departments were assisting with road barricades and debris removal.
The National Weather Service said a tornado warning has been issued in southern Alabama.
Meteorologist Jason Beaman in Mobile, Alabama, said warnings were issued for Clarke and Choctaw counties Thursday evening. He said a storm was rushing toward both counties with very strong signs of a tornado.
The National Weather Service also issued a flash-flood watch for northern parts of Louisiana. Forecasters predicted multiple rounds of strong thunderstorms would produce 2 to 4 inches of rain, and perhaps 6 inches in some parts of Louisiana.
“Heavy rain from waves of storms could renew flooding over north Louisiana,” said Cynthia Palmer, a forecaster at the weather service’s office in Shreveport, Louisiana.
The ground remains saturated in that part of the state, which saw record flooding earlier this month, Palmer said.
In northern Mississippi, forecasters said thunderstorms would bring rainfall amounts of 2 to 4 inches. A flash-flood watch was in effect through Thursday evening.
As the system moves east, strong storms were expected to develop Thursday over Alabama, where forecasters say the main threats will be tornadoes, winds of up to 70 mph, quarter-sized hail and heavy rains. Forecasters said storms in central Alabama are expected to continue through 3 a.m.
In Georgia, forecasters said more than 4 inches of rain could fall in western parts of the state.
