A series of tornadoes crossed Oklahoma and Kansas Sunday afternoon and evening.
Emergency officials in Oklahoma say at least 21 people have been injured across the state as a massive storm system blasts through the Plains and upper Midwest.
Tornadoes have been reported in Kansas, Iowa and Oklahoma. One touched down southeast of Oklahoma City, reducing homes in one mobile home park to splinters and rubble and flipping tractor-trailers on a nearby highway. At least one person has been found dead at the mobile home park.
As of Sunday night, several counties in Oklahoma reported widespread damage.
“We got a tornado on the ground right now guys! There is some large debris in the air - right here!” Jim Cantore, a Weather Channel meteorologist said during televised coverage.
In Wichita, Kansas, storm chasers captured on video a large tornado touching down that toppled power lines and trees.
Near Wellston, northeast of Oklahoma City, a tornado at least a mile wide crossed, as it knocked over and split open tractor trailers.
At a trailer park in Shawnee, Okla., the tornado shredded almost every home on the property leaving residents to pick up the pieces.
“Everything is completely gone, just the plywood [is left] sitting on top of the I-beams,” said Jon Welsh, a helicopter reporter for NBC affiliate KFOR-TV.
