Severe storms tore through parts of the US again on Wednesday, spawning damaging tornadoes, producing massive hail and killing two people in Tennessee and one person in North Carolina.

A storm that rumbled across north-eastern Tennessee brought high winds that knocked down powerlines and trees. Claiborne County sheriff Bob Brooks said a 22-year-old man was in a car struck by one of the trees.

Wednesday afternoon, a tornado emergency — the weather service’s highest alert level — was issued for an area south of Nashville including the towns of Spring Hill, Chapel Hill and Eagleville.

The National Weather Service had previously reported a likely tornado on the ground in nearby Columbia, about 45 miles (72 kilometres) south of Nashville.

People in Columbia were injured and homes were damaged, according to Lynn Thompson, assistant director of Maury County 911. Mr Thompson told The Associated Press that he could not provide any further details: “We’re getting overloaded right now.”

Rita Thompson, Marketing & Communications director with Maury Regional Health, said the hospital had received five patients. One died, another was in serious condition and three had injuries that were not life-threatening.

The Federal Aviation Administration issued a temporary ground stop at Nashville International Airport because of the weather, media outlets reported.

Northeast of Nashville, a flash flood emergency was issued for Sumner and Robertson counties including the cities of Hendersonville and Gallatin.

The National Weather Service said water rescues were ongoing in those areas and described the flooding from heavy thunderstorms as life-threatening.

“Do not attempt to travel unless you are fleeing an area subject to flooding or under an evacuation order,” the weather agency alert said.

The National Weather Service in Nashville on Wednesday evening issued a tornado watch for parts of Arkansas, Mississippi, Missouri and Tennessee until 3am central daylight time.

The weather service continued issuing tornado warnings into the night, mostly in Tennessee, but also in Missouri, Alabama, Georgia and Texas.

In North Carolina, a state of emergency was declared for Gaston County on Wednesday evening following a large storm. First responders were working to clear roads of downed power lines and broken trees and were helping residents, officials said.

The New Hope Fire Department responded to a tree down on a car. One person in the car was killed and another was taken to a hospital, officials said.

More than 135,000 customers had lost power in the state as of Wednesday evening, according to PowerOutage.us.

The National Weather Service confirmed tornadoes touched down on Tuesday in western Ohio: five in Warren County and one each in Darke, Mercer and Auglaize counties.

The weather service said crews are still surveying areas in other counties to determine if tornadoes struck there, as well. The strong storms also brought hail and heavy rains to the state and knocked out power to thousands of utility customers.

In Michigan, weather service meteorologist Nathan Jeruzal said the tornadoes there touched down one each in Kalamazoo, Cass and Branch counties — all in the southwestern part of the state. Governor Gretchen Whitmer declared a state of emergency for four counties.

Kalamazoo County’s Portage area was hard hit as a FedEx facility was ripped apart and more than a dozen mobile homes were destroyed. About 50 people temporarily were trapped inside the damaged facility because of downed power lines.

More than a dozen homes were destroyed in a mobile home park in adjacent Pavilion Township and 16 people were injured, said Kalamazoo County sheriff Richard Fuller.

In southern Indiana, the National Weather Service confirmed a tornado touched down early on Wednesday. The Clark County Emergency Management Agency said the storm damaged 24 structures, including homes in a subdivision north of the city of Sellersburg, located about 12 miles (19 kilometres) north of Louisville, Kentucky.

Tornadoes were also confirmed in Pennsylvania just outside Pittsburgh, in central Arkansas and in northern West Virginia. The West Virginia twister was at least the 11th tornado this year in the state, which sees two tornadoes in an average year.

Baseball-sized hail was reported on Wednesday in areas just south-west of St Louis. Heavy downpours caused flash flooding and at least one water rescue near Sullivan, a town that was struck by a small tornado just two days earlier. Damaging hail also was reported in the Kansas City area.

On Monday, parts of the central United States were battered by heavy rain, strong winds, hail and tornadoes, including a deadly twister that ripped through an Oklahoma town. Both the Plains and Midwest have been hammered by tornadoes this spring.
