LITTLE ROCK, Ark. - Severe storms spawned a dozen reported tornadoes in Oklahoma and Arkansas on Thursday, injuring at least five people and sending residents scrambling for cover 10 days after a powerful twister killed 24 people in Oklahoma.
One tornado warning included Cushing, Oklahoma, a critical hub for the US oil markets northeast of Oklahoma City, but the storm passed through without damaging tanks that store more than 50 million barrels of oil, said Bob Noltensmeyer, Cushing's emergency management director.
The storms were not expected to taper off until later on Thursday night and more storms are expected on Friday, said Greg Dial, a meteorologist with the National Weather Service's Storm Prediction Center.
"Tomorrow will be round two, we will have another round of severe weather, similar area, Oklahoma into the lower Mississippi Valley area," Dial said.
Several counties to the north and south of Oklahoma City were under tornado warnings at various times on Thursday.
