Tornadoes slammed into Canadian County, Oklahoma, just west of Oklahoma City, officials said.

"We have two confirmed fatalities," Sheriff Randall Edwards of El Reno, Oklahoma told CNN.

"The tornadoes just went through our county less than an hour ago," he said. "We've got multiple gas leaks. We've had several injured. Up to dozens." People "blown off of (interstate) I-40."

Oklahoma Governor Mary Fallin urged people to stay safe indoors.

"Stay inside, listen to the TV or radio, stay underground," Fallin said.

"On the news they've been showing pictures of the tornadoes on the ground. They're huge also, and this is a very dangerous time right now," she warned.

Oklahoma City did not immediately have damage reports.

"So far ... Oklahoma City has been spared but the night is young. The metro area around us has been hit hard. And all of our resources are going to be stretched," the city's mayor Mick Cornet said.
