A monstrous tornado, carving a track that could rival the longest on record, has ripped through the middle of the US in a storm front that killed dozens and tore apart a candle factory, crushed a nursing home, derailed a train and smashed an Amazon warehouse.
“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 the candle factory in Mayfield, where 110 people were working overnight 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 and EMS director.
In Kentucky alone, 22 were confirmed dead by Saturday afternoon.
But Mr Beshear said upwards of 70 may have been killed when a twister touched down for more than 320 kilometres in his state and that the number of deaths could eventually exceed 100 across 10 or more counties.
The death toll of 30 across five states includes four people in Tennessee; two in Arkansas, where a nursing home was destroyed; one in Missouri and six in Illinois, where an Amazon facility was hit.
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 355 kilometres through Missouri, Illinois and Indiana.
But Mr Genzini said this twister may have had touched down for nearly 400 kilometres.
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.
'I did not think I was going to make it'
The missing at the candle factory included Janine Denise Johnson Williams, a 50-year-old mother of four whose family members kept vigil at the site on Saturday.
“It's Christmas time and she works at a place that's making candles for gifts," her brother, Darryl Williams, said.
He said Ms Johnson Williams called her husband overnight to report the weather was getting bad. It was the last time anyone heard from her.
Kyanna Parsons-Perez, an employee at the factory, was trapped under about 1.5 meters of debris for at least two hours until rescuers freed her.
In an interview with NBC's Today, she said it was "absolutely the most terrifying" event she had ever experienced.
"I did not think I was going to make it at all."
Just before the tornado struck, the building's lights flickered. She felt a gust of wind, her ears started "popping" and then: "Boom. Everything came down on us".
People started screaming, and she heard other workers praying.
Among those who helped rescue the trapped workers were inmates from the nearby Graves County Jail, she said.
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 didn't know how many. She said it could take a day and potentially longer to remove all of the rubble.
Biden promises government aid
President Joe Biden approved an emergency disaster declaration for Kentucky on Saturday and pledged to support the affected states.
"I promise you, whatever is needed — whatever is needed — the federal government is going to find a way to provide it," Mr Biden said.
At least six people died at the Amazon facility in Edwardsville, Illinois, police chief Mike Fillback told reporters on Saturday morning.
The roof of the building was ripped off and a wall about the length of a football field collapsed.
Several workers remained unaccounted for as rescuers searched for anyone who might still be trapped in the facility, authorities said.
"This is a devastating tragedy for our Amazon family and our focus is on supporting our employees and partners," Amazon spokesperson Richard Rocha said in a written statement.
Workers at a National Weather Service office had to take shelter as a tornado passed near their office in Weldon Spring, Missouri.
"This was an incredible storm that lasted a long time and covered a lot of territory," said Larry Vannozzi, meteorologist in charge of the National Weather Service office covering the Nashville area.
Meteorologists had not determined whether the storm spawned a single tornado or multiple tornadoes, he said.
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 said.
Five people had serious injuries, he said.
Another person died when the storm hit a Dollar General store in nearby Leachville, Hutchinson said.
"Probably the most remarkable thing is that there's not a greater loss of life," Govenor Asa Hutchinson said after touring the wreckage of the nursing home.
"It is catastrophic. It's a total destruction."
