On Sunday, Mayfield, Kentucky, a cleanup worker walked past damaged trees and debris at the end of the day.

Officials said that as recovery work continues after the historic storm, the damage caused by dozens of tornadoes that hit the south and midwest over the weekend may take days to determine.

Kentucky, Tennessee, Arkansas, Illinois, Missouri and Mississippi were hit by dozens of tornadoes on Friday night and Saturday morning. This was an unusual outbreak, partly due to unusually warm temperatures.

The storm left a lot of rubble, and at least 14 people were killed in Illinois, Tennessee, Arkansas, and Missouri.

Six people were confirmed dead in an Amazon facility in Illinois, and at least one person died in a nursing home in Arkansas.

According to the St. Louis Post, an 84-year-old woman was killed when her home in Defiance, Missouri, was bombed. A young child also died in the state.

However, most deaths occurred in Kentucky, and it is estimated that dozens of people may have been killed. According to the Associated Press, at least four tornadoes hit the state, one of which has a very long path, about 200 miles.

Kentucky Governor Andy Beshear warned residents that as rescuers clear the rubble, more deaths may be announced in the coming days.

Meteorologists from the National Weather Service explained the extent and intensity of some tornadoes that landed.

According to the National Weather Service’s Storm Prediction Center, tornadoes from the same storm are believed to have hit Kentucky, Arkansas, Illinois, Indiana, Mississippi, Missouri, Ohio, and Tennessee.

As of Sunday, Missouri and Illinois have confirmed at least four EF-3 and five EF-2 tornadoes. When the wind speed reaches between 111 mph and 165 mph, the EF-3 tornado is considered severe or severe.

In Kentucky alone, the areas between Bowling Green and Saloma and between Casey and Beaver Creek may also be hit by the EF-3 tornado.

NWS warned that it may take some time to know the full extent of the storm. Their investigation of the tornado incident will continue in the next few days. The organization stated that they are facing communication interruption difficulties and hope to avoid interference with search and rescue operations.

According to the Kentucky National Weather Service, more experts are expected to arrive in the area on Monday to investigate the damage.

A woman shared the tragic story of hiding in a warehouse bathroom when the EF-3 tornado hit and the building collapsed.

"We were just standing there and talking. That was when we heard the noise. It felt like the floor started to move. We all got closer. We all started screaming," Gerah Grove told the Post.

Hargrove told the newspaper that emergency rescuers arrived at the scene within 10 minutes and had to rescue workers from the rubble.

Amazon said it has pledged $1 million to the Edwardsville Community Foundation to support rescue efforts.

"The news from Edwardsville is tragic. We are heartbroken for losing our teammates there, and our thoughts and prayers are with their families and loved ones," Amazon founder Jeff Bezos tweeted Saturday night .

"Everyone in Edwardsville should know that the Amazon team is committed to supporting them and will accompany them in this crisis," he continued. "We express our most heartfelt thanks to all the incredible first responders who worked tirelessly on the scene."

After several tornadoes destroyed parts of Kentucky, search and rescue operations are still effective throughout western Kentucky. Many communities were destroyed.

The two hugged each other from the devastation caused by a series of deadly tornadoes that swept across Kentucky and other states from Friday night to Saturday morning. A factory building in Mayfield, Kentucky collapsed, with more than 100 people inside, and the damage was particularly severe.

On Sunday, as the number of missing workers in a candle factory destroyed by a tornado fell, there was a glimmer of light. Officials had previously worried that nearly 100 workers might be killed when the building collapsed.

According to reports, about 110 people were working night shifts at the factory when the tornado struck. A spokesperson for the factory owner said on Sunday that 101 of the approximately 110 employees had been missing. The spokesperson said that out of 101 people, 9 people were killed.

Bashir said that the state has not verified the figures from the factories, but if they are accurate, "a better situation and the miracle we hope for may occur," he said.

At a press conference on Sunday evening, Beshear said that more than 1,000 houses were destroyed and thousands of people were left homeless.

"I don't think we will ever see destruction of this magnitude," he said.

Bashir declared a state of emergency on Saturday morning. A few hours later, President Biden approved emergency federal assistance to the state. The president is expected to travel to Kentucky and meet with Bashir this week.

Bashir said he visited several disaster-stricken areas, including Dawson Springs, the city where his father, former Kentucky governor Steve Bashir grew up.

"I saw almost half of the town destroyed. This is a special place. There are about 3,700 people and the destruction is indescribable," he told NPR earlier on Sunday.

"A block away from my grandparents' house-everything is gone, it's gone. I want to say that we are going to some places from house to house, but there is no door. That community will lose a lot of people," he added.

In Mayfield, Kentucky, aerial images depict widespread destruction throughout the city.

"I was there yesterday and it was worse than the image," Beshear told NPR, referring to the candle factory. "It's more than 15 feet of steel. The car in the parking lot went through the corrosive drum roof. Chemicals."

The director of the Kentucky Emergency Management Department, Michael Dossett, said on Sunday night that the process of establishing long-term shelters for the displaced would begin immediately.

The Secretary of Homeland Security, Alejandro Mayorkas, stated that FEMA will work in the state "until the restoration is complete."
