A tornado ripped through Billings, Mont. Sunday, damaging downtown businesses, including a bar, casino and auto glass shop.

"I'm in a total daze," said Kevin Massick, whose Fas-Break Auto Glass store had its roof torn off and dumped into a nearby creek.

"It's a total loss," Massick said, his face creased with emotion and tears welling up in his eyes. "I don't know what I'm going to do. Start over, I guess."

The powerful twister also tore the roof off Rimrock Auto Arena, 10,000 seat sports stadium.

"It would touch down and suck back up and touch down and touch down again," said Montana Trooper Toman Baukema, who saw the tornado from a patrol station about a mile away.

Despite the damage wrought by the tornado, estimated to have reached wind speeds between 111 and 135 mph, there were no reports of injuries.

Montana National Guard troops are now on the scene assisting with the cleanup.
