MOORE, Okla. - All that is left of Shayne Patteson's three-bedroom home is the tiny area where his wife hunkered down under a mattress to protect their three children when a tornado packing winds of at least 200 mph slammed through his neighborhood.

Patteson's home was among as many as 13,000 homes damaged or destroyed Monday when the twister plowed through the Oklahoma City suburb of Moore.

"The tornado that we're talking about is the 1 or 2 percent tornado," Oklahoma Department of Emergency Management Director Albert Ashwood said of the twister, which measured a top-of-the-scale EF5 with winds of at least 200 mph. "This is the anomaly that flattens everything to the ground."
