A tornado kicked up debris in an Oklahoma City suburb and threatened a number of tourist attractions on historic Route 66 before growing into a larger storm that rolled across rural parts of central Oklahoma.
Television footage Sunday showed a tornado at Edmond . The storm threatened a novelty soda-pop store and a historic barn in the small town of Arcadia, then grew into a larger storm as it moved northeastward a few miles north of the Turner Turnpike between Oklahoma City and Tulsa.
The Storm Prediction Center had forecast a moderate risk of severe weather in Oklahoma and adjacent portions of Kansas and Missouri.
TV video also showed power flashes from transformers blowing out as they were hit by high winds or debris.
