A child and adult were killed in a series of tornadoes that crossed Oklahoma over the weekend.

Several buildings were reduced to rubble after a tornado ripped through downtown Sulphur. Several houses lost their roofs to the wind.

The Murray County Sheriff's Office warned people to stay away from the town.

More than 27,000 customers across the state were without power Sunday afternoon according to poweroutage.us.

Powerful storms have hit Oklahoma, Nebraska, Kansas, Missouri, Arkansas and Texas since Friday.

Dramatic video on X showed a tornado crossing I-80 in Waverly, Nebraska, on Friday as traffic continued down the road.

Footage I took driving on I-80W yesterday. Tornado popped up on the horizon and we watched it cross over the interstate. I've always kinda wanted to witness a tornado like this at least once in my life. Unfortunately there was some destruction that came with it. #NebraskaTornado pic.twitter.com/XHxdW6g5hd
