Waves of storms turn deadly in Tennessee and more twisters are hitting the Southeast

(CNN) — Strong storms tracking through the central and eastern US Wednesday killed at least two people in Tennessee and as night fell, flash flooding and more tornadoes were slamming the state – including one twister that carved a path of destruction in communities south of Nashville.

Tornado warnings also were in effect late Wednesday in several southern states, including in northern Alabama, where a “large and destructive tornado” was in the area of Henagar, a city of a couple thousand people roughly 55 miles east of Huntsville, the National Weather Service said. A tornado warning also was issued earlier Wednesday night in the Huntsville area.

The National Weather Service issued tornado watches for parts of Alabama, Georgia, Arkansas, Mississippi and Tennessee until 3 a.m. CT Thursday. A tornado watch means severe thunderstorms and tornadoes are possible in the watch area.

The National Weather Service said it had four tornado reports Wednesday from Tennessee, with two from Maury County, where a tornado emergency had been in effect. A “confirmed large and destructive tornado” was near the city of Spring Hill around 5:50 p.m. CT, the weather service said.

At least one person was killed and four others were injured in Maury County during the tornado, Maury Regional Medical Center spokesperson Rita Thompson told CNN. Three of those patients have non-life-threatening injuries and one is in serious condition, Thompson said.

The area had widespread damage, with trees down, officials in the county told CNN. Buildings were also damaged, but Maury County Commissioner Eric Previti said he wasn’t aware of the magnitude.

“We are urging for everyone to stay off of the roads. If you can stay at home, stay home,” the Maury County Office Of Emergency Management posted on Facebook.

A flash flood emergency was issued Wednesday evening for Robertson and Sumner Counties in Middle Tennessee along the state line with Kentucky and around 20 to 30 miles north of Nashville, according to the weather service.

“At 6:56 pm CDT, water rescues and very dangerous flooding are occurring in the emergency area,” weather officials said. Radar estimates show 4 to 7 inches of rain have fallen across these counties today, and more heavy rainfall will move across the region over the next several hours.

An official with the Robertson County Emergency Management Agency said there were a few water rescues but no immediate reports of injuries.

The first fatality from the storms was reported in Claiborne County, Tennessee, Wednesday morning. A tree fell onto the person’s car amid intense storms, according to the county’s emergency management office. The person has not been identified.

Dangerous storms with damaging winds, large hail and tornado warnings have been ongoing in several states since Wednesday morning. The hazardous weather is playing out just a day after powerful tornadoes and storms swept through southwestern Michigan, destroying homes and businesses and injuring several residents.

The severe weather is forecasted to shift into the Southeast and Mid-Atlantic on Thursday, bringing with it more hail, damaging winds and the possibility of a few tornadoes.

Here’s the latest on Wednesday’s storms and destruction in Tennessee and Tuesday’s damage in Michigan:

• Chaotic severe weather stretch: April to June is the most active time for tornadoes in the US, and May is typically the busiest month. This year has been no exception. At least one tornado has been reported in the US every day since April 25 – a streak of 14 days and counting.

• Damage and debris on I-65: The Tennessee Department of Transportation said it was sending crews to an area near Interstate 65 and State Road 99 where there was damage and debris. “1 lane is blocked on I-65S at MM 47 in Maury Co. after a reported tornado passed over the interstate. Reports from the scene are that cars and signs in the area were damaged,” transportation department spokesperson Rebekah Hammonds said on X.

• Mobile home park struck by tornado: More than a dozen people were injured at a mobile home park in Pavilion Township in Kalamazoo County, Michigan, following a tornado Tuesday, according to a city official. Fifteen to 20 people had minor injuries and were transported to two area hospitals, according to the county’s emergency management spokesperson Andrew Alspach.

• One Michigan town may have been hit twice: At least one tornado, possibly two, hit Portage Tuesday evening, as the area faced two tornado warnings in just over an hour, the National Weather Service said. Homes and businesses in the city sustained significant damage, but there were no serious injuries, according to town officials. A tornado ripped a large hole into a FedEx facility. A spokesperson for the Kalamazoo County administrator’s office told MLive.com that around 50 people were trapped in the facility for a few hours. CNN has been unable to verify that report. Portage public safety director Nicholas Armold later said all employees were accounted for when emergency responders arrived.

• Damage reported in at least two other Michigan counties: Multiple homes and businesses were destroyed after a possible tornado touched down in Centreville on Tuesday, according to St. Joseph County Undersheriff Jason Bingaman. The storm damage ripped off roofs and flattened homes “completely down,” Bingaman told CNN. At least seven homes were destroyed in nearby Branch County, according to Emergency Management Director Tim Miner.

• First-ever tornado emergency in Michigan: Parts of Branch County, including Union City, were placed under Michigan’s first tornado emergency when “a large and destructive tornado” was over the area Tuesday, according to the National Weather Service. Tornado emergencies are the most extreme tornado warnings and are only issued when a tornado threatens catastrophic damage and loss of life, often in a populated area.

Tornado threat continues Wednesday

Nearly 3.7 million people were under a Level 4 of 5 risk of severe thunderstorms Wednesday night, according to the Storm Prediction Center. Within this risk are parts of Alabama, Missouri, Illinois, Kentucky and Tennessee — including Nashville.

An additional 590 million people from Texas, through much of the Ohio Valley and into the mid-Atlantic and Northeast, are under a Level 2 of 5 or Level 3 of 5 risk.

Powerful storms with damaging winds, hail bigger than baseballs and tornado warnings have been roaring across multiple states since Wednesday morning.

Some areas that endured an initial round of severe storms early Wednesday are at risk for another round later in the day – Tennessee is a prime example.

The repeated rounds of storms Wednesday will also deliver torrential rainfall and raise the risk of flooding.

“The greatest flash flooding threat also overlaps with the risk of severe thunderstorms, centered over Kentucky and Tennessee as well sections of neighboring states,” the National Weather Service said. A Level 3 of 4 risk of flooding rainfall is in place here, according to the Weather Prediction Center.

Rainfall rates could reach 2 inches per hour, which could dramatically increase the possibility of flash flooding. Locations worked over by multiple heavy storms could record more than 4 to 5 inches of rain.
