(Reuters) - More than 30 people were injured and dozens of buildings damaged when a tornado hit Tulsa early on Sunday, causing power outages to about 17,000 customers after powerful winds snapped utility poles and downed trees in the Oklahoma city, officials said.
The tornado flipped cars, ripped apart buildings and blew windows out of a high-rise building, images from local TV broadcaster KTUL showed.
Oklahoma emergency officials told local media there were no deaths from the tornado classified by the U.S. National Weather Service as an EF-2 on the Enhanced Fujita Scale, meaning it had winds of about 125 miles per hour (200 kph).
Tornadoes coming in August and hitting at night are rare for Tulsa, the service said.
"The tornado that occurred did so suddenly and unexpectedly," Tulsa Mayor G.T. Bynum said in a Facebook post.
The Public Service Company of Oklahoma said as of Sunday afternoon, it had restored power to more than 11,000 customers.
