President Barack Obama told Oklahoma Governor Mary Fallin the federal government "stands ready to provide all available assistance," a White House statement said.
The Monday storm came in the wake of destruction that hit the area on Sunday night.
Andrew Griffin at Red Dirt Report earlier today wrote, "Driving around the area near Dale, Bethel Acres and then back towards Lake Thunderbird and on into Norman, we criss-crossed the areas where the Sunday tornado had passed through. Twisted bits of metal, downed power poles and homes that were badly damaged by the destructive force of the tornado were clearly visible in these areas of Oklahoma, Pottawatomie and Cleveland counties.
"As we write this story, a new, powerful tornado formed west of Newcastle and went east-northeast, right through Moore and parts of the southside of Oklahoma City. The devastation is massive. People are injured, possibly dead. This is as bad – or at least more widespread in terms of damage – as the notorious May 3, 1999 tornado that hit Moore."
