A monstrous tornado, carving a track that could rival the longest on record, has ripped across the middle of the US in a stormfront that killed dozens across five states.
“I pray that there will be another rescue. I pray that there will be another one or two,” Kentucky governor Andy Beshear said, as crews sifted through the wreckage of a candle factory in Mayfield, where 110 people were working overnight on Friday when the storm hit.
Forty of them were rescued.
“We had to, at times, crawl over casualties to get to live victims,” said Jeremy Creason, the city’s fire chief.
In Kentucky alone, 22 were confirmed dead by Saturday afternoon, including 11 in and around Bowling Green.
But Mr Beshear said upwards of 70 may have been killed when a twister touched down for more than 200 miles in his state and that the number of deaths could eventually exceed 100 across 10 or more counties.
The death toll of 36 across five states includes six people in Illinois, where an Amazon facility was hit; four in Tennessee; two in Arkansas, where a nursing home was destroyed; and two in Missouri.
If early reports are confirmed, the twister “will likely go down perhaps as one of the longest track violent tornadoes in United States history,” said Victor Genzini, a researcher on extreme weather at Northern Illinois University.
The longest tornado on record, in March 1925, tracked for about 220 miles through Missouri, Illinois and Indiana. But Mr Genzini said this twister may have touched down for nearly 250 miles. The storm was all the more remarkable because it came in December, when normally colder weather limits tornadoes, he said.
Debris from destroyed buildings and shredded trees covered the ground in Mayfield, a city of about 10,000 in western Kentucky.
Twisted metal sheeting, downed power lines and wrecked vehicles lined the streets. Windows and roofs were blown off the buildings that were still standing.
Kentucky state trooper Sarah Burgess said rescue crews were using heavy equipment to move rubble at the candle factory.
Coroners were called to the scene and bodies were recovered, but she did not know how many. She said it could take a day and potentially longer to remove all of the rubble.
Rescue efforts were complicated because Mayfield’s main fire station and emergency services hub were also hit by the tornado, Mr Creason said.
President Joe Biden approved an emergency disaster declaration for Kentucky on Saturday and pledged to support the affected states.
Mr Biden said: “I promise you, whatever is needed — whatever is needed — the federal government is going to find a way to provide it.”
Six people were killed in the collapse of the Amazon warehouse in Edwardsville, Illinois, with another injured worker airlifted to a hospital, fire chief James Whiteford said.
Investigators searched the rubble throughout the day for additional victims and 45 people survived, Mr Whiteford said.
Authorities were uncertain on Saturday evening whether anyone was still unaccounted for because workers were in the midst of a shift change when it was struck by the tornado about 8.30 pm on Friday.
Amazon spokesperson Richard Rocha said in a written statement: “This is a devastating tragedy for our Amazon family and our focus is on supporting our employees and partners.”
The Retail, Wholesale and Department Store Union, which has been trying to organise workers at an Amazon facility in Alabama, criticised the company for keeping the Illinois site open during a weather emergency.
Missouri governor Mike Parson’s office said the storms killed at least two people in the state and initial assessments indicate they destroyed or did major damage to hundreds of homes and buildings.
Workers at a National Weather Service (NWS) office had to take shelter as a tornado passed near their office in Weldon Spring, Missouri, about 30 miles west of St Louis.
“This was an incredible storm that lasted a long time and covered a lot of territory,” said Larry Vannozzi, meteorologist in charge of the NWS office covering the Nashville area.
He added meteorologists have not determined whether the storm spawned a single tornado or multiple tornadoes.
In Arkansas, a tornado struck a nursing home in Monette, killing one and trapping 20 people inside as the building collapsed, Craighead County judge Marvin Day told The Associated Press.
Another person died when the storm hit a Dollar General store in nearby Leachville, governor Asa Hutchinson said.
“Probably the most remarkable thing is that there’s not a greater loss of life,” Mr Hutchinson said after touring the wreckage of the nursing home.
“It is catastrophic. It’s a total destruction.”
Governor Bill Lee on Saturday toured tornado-torn parts of western Tennessee in which four people had been killed.
Mr Lee travelled to Tiptonville and then Dresden, a small town of about 3,000 that saw its downtown corridor ripped to shreds.
“This is about the saddest thing I’ve ever seen,” said Mr Lee, who has had three fatal tornadoes rip through the state during his first term in office.
