Oct. 11 (UPI) -- Multiple tornadoes touched down in Oklahoma during severe thunderstorms late Sunday and early Monday after heavy rains and lightning rolled across several states in the region, officials said.
Officials said there were at least five twisters reported in Oklahoma and more than 20,000 homes and businesses lost power due to the storm.
There were no immediate reports of deaths or injuries.
During the severe weather, major hail also damaged vehicles in Norman, Okla., and the National Weather Service warned of flash flooding due to several inches of rain that fell over a two-hour period.
Tornado warnings were issued for a number of counties across Oklahoma overnight Sunday and the storm rolled across several other states, including parts of Kansas, Missouri, Arkansas and Texas.
Officials in Coweta, Okla., said a tornado there caused damage to a gas station and nursing home, and downed electrical wires and trees.
Authorities said they would have a more complete picture of the damage on Monday.
Officials said the storm damaged a high school baseball facility, knocked over fences and toppled an air conditioning unit. Coweta school officials canceled all classes for Monday.
Oklahoma Gas & Electric said on its website that fewer than 5,000 customers were still without electricity in the Oklahoma City area by early Monday.
Forecasters said the severe weather in Oklahoma is expected to continue until at least Wednesday.
