Oklahoma and other states in the Great Plains are bracing for more severe weather.

The National Weather Service is warning that there's a moderate risk of severe thunderstorms Saturday. The greatest risk is from western Kansas into western Oklahoma, where tornadoes and large hail are likely.

The storms come just days after storms that produced more than 50 tornadoes across the Plains.

Storms on Friday night caused some flooding in Oklahoma. In Shawnee, the Red Cross opened an evacuation site because of concerns that a dam was close to cresting, threatening some homes.
