COLE, Okla. (AP) — Strong storms with tornadoes and hail killed at least two people in the central U.S., injuring others, destroying homes and leaving thousands without power.

The National Weather Service began issuing tornado and severe thunderstorm warnings Wednesday evening in Oklahoma, Kansas and Iowa, with forecasters warning people to find shelter.

Central Oklahoma saw tornadoes, including one that raced through the communities of Shawnee and Cole.

At least two people were killed in the small town of Cole in McClain County, about 25 miles (41 kilometers) south of Oklahoma City, authorities said. There also were injuries ranging from cuts and bruises to some requiring hospitalization, although the numbers weren’t immediately clear as hundreds of people fanned out in search operations.

“It is reasonable to expect possibly more based on the damage that we’ve seen,” McClain County Deputy Sheriff Scott Gibbons said on NBC’s “Today Show” of the potential for additional deaths to be confirmed.

Power lines also were torn down, trees toppled, and homes and other buildings badly damaged or destroyed. Oklahoma Baptist University in Shawnee and an airport were damaged before the tornado moved away and weakened.

“We do not have a number of homes or businesses damaged, but we do know that significant damage occurred,” Benny Fulkerson, a spokesperson for the Oklahoma Department of Emergency Management, said in a statement late Wednesday.

At the peak of the severe weather, more than 23,000 customers were without electricity throughout Oklahoma, according to

KFOR-TV reported that residents south of Oklahoma City said they were trapped in their underground shelters, mailboxes were blown away, and emergency crews used GPS to find addresses, according to the McClain County sheriff.

Two people in the town of Cole rode out the storm in a manhole and were not hurt, the television station reported.

More storms with a chance of producing tornadoes were forecast for Thursday night from Texas to Wisconsin by the National Weather Service’s Storm Prediction Center.

“A mix of supercells and storm clusters is expected” with possible tornadoes across eastern Texas before the storm moves northward across Arkansas and into Missouri. “Large hail, and possibly a tornado or two” could occur from eastern Missouri, across Illinois into Wisconsin, according to the prediction center.

Video from Storyful shows a huge supercell looming over Slaughterville, southeast of Oklahoma City, on Wednesday.

According to Storyful, Frank Knoles said he recorded this footage in Slaughterville. A significant tornado was confirmed nearby, sparking warnings from the National Weather Service for residents to take shelter. Check out the video below:

Another video from Storyful shows timelapse footage capturing storm clouds rotating over Norman, Oklahoma, on Wednesday. At least nine tornadoes touched down in the state, leaving at least three people dead, local media reported, citing officials.

Footage posted to Twitter by @ArtByRicky shows the clouds swirling overhead. “I was right under it,” the source said, according to Storyful.

Storms this spring have spawned tornadoes in the South, Midwest and Northeast, killing dozens of people.

An April 1 storm produced tornadoes that killed at least 32 people from Arkansas to Delaware, and days later a tornado left five dead in Missouri. At least 26 died in Mississippi and Alabama when tornadoes during late March storm carved a path of destruction through the Deep South.
