OKLAHOMA CITY — Severe storms and tornadoes battered Oklahoma early Sunday, tossing cars and ripping roofs off buildings in the middle of the night and leaving tens of thousands of homes and businesses without power. Among numerous injuries, 11 people required hospitalization, authorities said.

Much of the damage was reported in and around the state capital of Oklahoma City, near the state’s center, but also scattered elsewhere around the state. The early morning storms set off tornado warnings that extended south to the Arkansas state line. Heavy rains caused flash flooding in some areas and one lightning-sparked house fire was reported.

More than 99,000 Oklahoma homes and businesses lost power during the overnight storms. By late Sunday afternoon, that number was reduced to around 24,000. No fatalities had been reported.

Richard Thompson, forecast chief for the National Weather Service Storm Prediction Center in Oklahoma, said he believes six or more tornadoes hit the state overnight.
