The powerful tornadoes that plowed through Lee County in Alabama and killed at least 23 people left a path of destruction that looked "as if someone had taken a blade and just scraped the ground," the county sheriff said Monday.
One of those tornadoes was an EF-4 with winds of 170 miles per hour, the National Weather Service determined on Monday afternoon.
At daybreak on Monday, emergency crews and residents witnessed more of the aftermath of the twisters that Sheriff Jay Jones called "catastrophic," and the search was on for survivors and more victims.
It appears that some people had only a five-minute warning Sunday afternoon before tornadoes ripped through the region.
A tornado watch was issued for the area around noon. The first tornado warning for Lee County was issued at 2:58 p.m. ET, and the first reports of damage came just five minutes later, CNN Meteorologist Gene Norman said, according to National Weather Service data.
It appeared that two tornadoes hit Lee County back-to-back within the span of an hour, Norman said.
A warning for a second tornado was issued at 3:38 p.m. ET, with the first reports of damage coming 13 minutes later.
At least a dozen tornadoes touched down in Alabama and Georgia on Sunday afternoon, according to the NWS.
The National Weather Service recorded EF-3 damage in southern Lee County. That classification means the damage was severe, with winds of 136 to 165 miles per hour.
How the destruction unfolded
Alabama's deadliest since 2011
The 23 deaths reported on Sunday marked the deadliest day for tornadoes in Alabama since the Tuscaloosa-Birmingham tornado that killed more than 200 people in 2011.
The victims, including children, died in Lee County, Jones said. At least 12 of those deaths occurred in an area about 5 to 6 miles south of the city of Opelika, he said.
Jones told CNN affiliate WRBL that he could not confirm the number of people injured but said that some people were receiving treatment for "very serious injuries."
According to John Atkinson, spokesman for East Alabama Medical Center, the Opelika campus received 60 patients on Sunday, but only four remain hospitalized Monday morning. The hospital's Valley campus received just one tornado victim.
"Thankfully, most were able to be treated and released," Atkinson said.
Lee County Coroner Bill Harris said as many as 20 people are unaccounted for but cautioned that some of them might have fled the storm and haven't been able to check in with their families.
Footage broadcast by WRBL showed trees destroyed by the powerful winds and debris from leveled homes piled up on the side of the road.
"Houses completely destroyed, homes -- just basically slabs left where once stood a home," Jones said.
"Massive damage. In specific areas the contents of one residence we know for a fact were located over 1,000 yards away, So we've got a very wide storm track that went through the area --- may have even been two storms, we're not sure. But massive damage," Jones said.
Smiths Station Mayor F.L. "Bubba" Copeland said the tornadoes leveled about 30 homes and demolished everything in their path, "unbelievable devastation" in such a short amount of time.
"Parts of a school to houses to a cell phone tower to businesses," he said of the affected structures.
"Something that we experienced was two 12-ton air conditioners that were on top of a school were picked up and thrown 35 feet into a cemetery. That's as heavy as if a school bus was thrown some 35 feet."
He described trailer homes that were "turned upside down with the wheels where the roof should be" and said "trees were cut off at about 15 feet in the air."
Copeland said rescues were made amid the wreckage.
"We were able to get to people that were trapped in their homes," he said. "We had to cut our way in."
Alabama Gov. Kay Ivey extended the state of emergency that had been issued last month statewide due to tornadoes and severe weather.
"Our hearts go out to those who lost their lives in the storms that hit Lee County today," she tweeted.
The National Weather Service in Birmingham said on Twitter it is currently on site and will be gathering the first bits of information to determine how strong the tornadoes were that tracked across Lee County.
"We'll be surveying this damage today, along with the two tracks that moved across Lee County. At least 5 tracks we know are going to be surveyed in our area across SE AL, with another possible track to survey in southern Bullock," it said.
Harris said coroners from surrounding counties were helping out with the mass casualty event. Rita Smith of the county's emergency management agency told WRBL that about 150 first responders had been working since the first tornado warning was issued.
"We are heartbroken for the people who have lost loved ones today. It is sad. You prepare and you prepare and you prepare, you guide citizens on what to do and sometimes even when we do everything right, mother nature has a mind of its own. We're very upset today about this," Smith said.
One woman, Delrico Eiland, shared video on Facebook of her 72-year-old aunt Earnestine Reese after her house and daughter's trailer were destroyed in Beauregard.
In the video, Reese, who suffered a broken hip and will have surgery this morning, is talking on FaceTime to her grandson Kingston Frazier who is away at college, Eiland says.
"I thank the Lord. You tell God 'thank you God.' You hear me? You hear me? Tell God thank you. Tell God thank you," she tells him.
"She's telling Frazier to tell God 'thank you' for sparing her life," Eiland told CNN. "She is a very strong woman."
A reunification center and shelter had been set up Sunday night at Providence Baptist Church in Opelika, congregants told CNN. At least 70 to 80 people sheltered in the church bsaement after the storm warnings.
Mark Wakefield, Alabama director of the Southern Baptist Disaster Relief said volunteers are helping with search and he talks about offering chaplain services for first responders and families.
Eufaula Mayor Jack Tibbs said on Facebook that the local airport and an industrial park "were hit pretty hard" and a fire station was taken out.
"All the damage can be replaced or repaired. Thank God, no one was injured," he said.
In Talbotton, Georgia, at least 15 structures were destroyed in a tornado on Sunday, including multiple homes and at least one apartment building, said Leigh Ann Erenheim, the emergency management director for Talbot County.
Six people suffered injuries, with the most severe being a possible broken leg, she said. Crews were checking on residents in the outer areas of town and working to open a shelter for people who have been displaced.
Vinton Copeland , pastor at Powell Baptist Church in Talbotton, Georgia, told CNN people there did not expect a tornado to hit the town.
"Complete apartments are gone and damaged. We have a shelter at our county high school for those affected. It's devastating and houses are gone and there are power lines decimated. Tough time," he said.
"The news only reported specifically about rural Alabama and all of a sudden it hit us quickly. We couldn't have planned for this."
Officials in South Carolina were also investigating whether a tornado was responsible for homes and businesses damaged in the area of North Augusta.
Georgia Gov. Brian Kemp issued declared a state of emergency in Grady, Harris, and Talbot Counties in the southern part of the state. He was expected to take an aerial tour of affected areas Monday afternoon.
The tornadoes are part of the same system that is bringing winter weather to much of the eastern United States this week, Norman said.
The NWS warned on Twitter that severe weather would continue into early Monday over the Southeast, with damaging winds, large hail, and isolated tornadoes possible.
