A line of severe thunderstorms and multiple tornadoes swept parts of four states on Friday, killing at least two people and leaving a trail of damage north and west of Nashville, Tennessee, authorities said.
And more severe storms are expected in the region through Friday night.
Two deaths were confirmed in Gallatin, about 30 miles northeast of Nashville, said Eddie Boatwright, a spokesman with the Tennessee Emergency Management Agency. No details were immediately available.
"We have significant damage in Nashville and in several counties close by," Boatwright said. Injuries have been reported, though he didn't know how many.
"These things are still rolling through here," he said, explaining that another severe storm was approaching the city.
As of 5:50 p.m. ET, six Tennessee counties were under a tornado warning, along with six counties in Mississippi and two in Arkansas. Earlier warnings were issued in Ohio, Indiana, Kentucky and Louisiana.
CNN meteorologists have reports of at least 10 tornadoes, along with 125 reports of large hail.
The National Weather Service's Storm Prediction Center advised that the tornado threats in Alabama and Mississippi were rapidly increasing as the evening approached.
Forecasters said there is a 60 percent probability of a tornado in an area from northeast Mississippi to northern Alabama and southern Tennessee.
"Several long-lived, violent tornadoes now appear increasingly likely," the prediction center states.
"The threat of strong to violent tornadoes will continue" as intense supercell thunderstorms move to the east and northeast across southern Tennessee, northern Alabama and possibly as far east as northwestern Georgia, forecasters said.
The NWS said two mobile homes were destroyed north of Charlotte, Tennessee. CNN meteorologist Reynolds Wolf reported tornadoes touched down near City Hall in Goodlettsville, north of Nashville, and in Greenbrier, northwest of the city.
"We have damage on Highway 49 east, which is between Charlotte and Ashland City," Dickson County Mayor Linda Frazier said. "We have homes damaged. We do have some injuries already being reported and the injured people that they could get to have already been transported to the hospital."
Frazier said she did not know the severity of the injuries. Because of downed trees, officials were having trouble getting through to survey the damage, she said.
"We are working feverishly to get through to the people to be able to assess the damage and get to anybody who will be in need of shelter or whatever else their needs may be," she said.
Reid Bell said he drove through a tornado in Benton County, near Holladay. "I was speaking to God most of the time," he said, adding that he was mainly concerned about downed power poles and power lines. "Of course, I wanted to get away from those."
Nashville station WVTF reported a roof had been blown off a building in Ashland City, northwest of Nashville. Hail was reported in several locations.
In Cheatham County, just west of Nashville, the storms damaged property but there were no immediately reported injuries, Doris Mays of the county's Emergency Management Agency told The Associated Press.
"We've got roofs off, trees down, lines down," Mays said. "There are a lot of people without power right now."
