Tornadoes spotted in Oklahoma as dangerous storms move across Great Plains

Tornadoes touched down Monday evening in rural Oklahoma and large hail pelted parts of Kansas as an outbreak of dangerous storms brought the possibility of strong twisters staying on the ground for many miles.

Forecasters have issued a rare high-risk weather warning for the two states, the first for Oklahoma in five years.

"You can't rely on waiting to see tornadoes before sheltering tonight," the National Weather Service said.
