VILONIA, Ark. (AP) -- Emergency officials searched for survivors Monday in the debris left by a powerful tornado that killed at least 14 people in Arkansas and carved an 80-mile path of destruction through suburban Little Rock.
The tornado that slammed into Vilonia, just north of the state's capital city, grew to about half a mile wide Sunday and was among a rash of tornadoes and strong storms that rumbled across the Midwest and South. The National Weather Service warned that more tornadoes, damaging winds and very large hail would strike Monday in parts of Mississippi, Alabama, Tennessee and Louisiana.
"We don't have a count on injuries or missing. We're trying to get a handle on the missing part," Arkansas Gov. Mike Beebe said Monday. "Just looking at the damage, this may be one of the strongest we have seen."
An earlier toll of 16 was changed to 14 after it was clear that two victims were counted twice, Arkansas governor's aide Matt DeCample said, though he still expects the overall death toll to rise.
Brandon Morris, spokesman for the Arkansas Department of Emergency Management, said crews were sifting through the rubble in the hope of uncovering survivors and to assess the damage.
"Right now, the main focus is life safety," Morris said. "We're trying to make sure everyone is accounted for."
Karla Ault, a Vilonia High School volleyball coach, said she sheltered in the school gymnasium as the storm approached. After it passed, her husband told her their home was reduced to the slab on which it had sat.
"I'm just kind of numb. It's just shock that you lost everything. You don't understand everything you have until you realize that all I've got now is just what I have on," Ault said.
The tornado that hit Vilonia and nearby Mayflower would likely be rated as the nation's strongest to date this year, as it has the potential to be at least an EF3 storm, which has winds greater than 136 mph, National Weather Service meteorologist Jeff Hood said.
In southeastern Iowa, a woman was killed when either a tornado or powerful straight-line winds caused a farm building to collapse. Another twister killed a person in Quapaw, Okla., before it crossed into Kansas, where it destroyed more than 100 homes and businesses, and injured 25 people in the city of Baxter Springs, according to Kansas authorities.
Sue McBride, a 71-year old retired sewing machinist in Baxter Springs, said she thought the tornado sirens could spell a false alarm. But then she saw and heard the twister approaching. She said debris flew all around as she ran into her home. She hunkered on her knees in her hallway with her head down as the tornado shattered her windows, spraying glass all over her.
"I didn't have one scratch on me and I was fine," McBride said from a Red Cross shelter in the city, where the tornado left a trail of shattered homes, twisted metal and hanging power lines.
The Arkansas twister shredded cars, trucks and 18-wheelers stuck along Interstate 40 north of Little Rock.
Among the ruins was a new $14 million intermediate school that had been set to open this fall.
"There's just really nothing there anymore. We're probably going to have to start all over again," Vilonia Schools Superintendent Frank Mitchell said after surveying what was left of the building.
Late Sunday, emergency workers and volunteers went door-to-door checking for victims and survivors.
"It turned pitch black," said Mark Ausbrooks, who was at his parents' home in Mayflower when the storm arrived. "I ran and got pillows to put over our heads and ... all hell broke loose."
"My parents' home, it's gone completely," he said.
Becky Naylor, 57, of Mayflower, said up to 22 people packed into her storm cellar as the tornado approached.
"People were pulling off the highways and were just running in," said Naylor. Men held the cellar doors tight to prevent the tornado from ripping them apart.
"It sounded like a constant rolling, roaring sound," she said. "Trees were really bending and the light poles were actually shaking and moving. That's before we shut the door and we've only shut the door to the storm cellar two times."
The other time was in 2011, during an EF2 tornado that followed nearly the same path and killed at least four people.
The Arkansas death toll stood at 14 at midday Monday - eight adults and two children in Faulkner County, three people in Pulaski County and one in White County.
President Barack Obama sent his condolences and promised the government would help with the recovery.
Sunday was the third anniversary of a 122-tornado day, which struck parts of Mississippi, Alabama, Tennessee, Virginia and Georgia and killed 316 people.
