Tornadoes in U.S. Midwest damage homes, displace residents

March 7 (UPI) -- The National Weather Service Storm Prediction Center said 29 tornadoes damaged homes, and injured and displaced residents in the midwest states of Missouri, Illinois and Kansas.

The severe weather Monday also created tennis ball-sized hail in some areas. In Missouri, Chief Carl Scarborough of the Sni Valley Fire Protection District in Oak Grove said from 100 to 200 people may have been displaced after "dozens and dozens" of homes sustained moderate to severe damage.

Scarborough told ABC News that 12 people were treated for injuries, three of whom were taken to the hospital. No injuries are considered life-threatening.

"There was a confirmed tornado touchdown in Oak Grove. Damage appears to be on the south side of town," the Oak Grove Police Department said in a statement. "There is Red Cross relief workers at the civic center for those in need of assistance."

In Kansas' Johnson County, officials shut down the Johnson County Executive Airport "due to multiple hangars and planes being damaged" in the storm.

"Everyone is asked to please stay away from the area until it is stabilized. Natural gas and power are being shut off," the Johnson County government said in a statement.

The National Weather Service warns that "a vast area of the Northern Plains and Upper Midwest are expecting high winds" on Tuesday.
