Oklahoma tornadoes: Cleanup continues in Norman after EF-1 tornado

Doak, who warned homeowners about fraudsters who typically arrive after natural disasters, urged affected residents to call (800) 522-0071 if they have concerns.

Friday's tornado touched down near Interstate 35 and Lindsey Street before skipping across the state's third-largest city. A tornado watch was issued at 3:59 that day. Three minutes later, the tornado touched down.

National Weather Service meteorologist Rick Smith said the first reports of damage came in eight minutes after the tornado watch was issued.

Nora Green, who was at Andrews Park on Sunday, is amazed more people weren't hurt given how fast the twister struck. She said she lives “about a half mile” from the heavily damaged city park.

“Usually we hear about it sooner … that it's coming this way,” Green said. “This one was scary because it just happened. And it happened in the middle of town, so I think it's amazing nobody was seriously injured or worse.”
