The first batch of severe weather in this year's tornado season has devastated an Oklahoma mobile home park. The storms across the area damaged buildings, tore off roofs and left debris strewn across roads. One person was killed and several were injured.

Tens of thousands of Oklahoma residents were without power Thursday as officials were assessing the damage.

Tulsa County Sheriff's Capt. Billy McKelvey said one person was killed in the mobile home park in a Tulsa suburb. It wasn't yet clear whether it was a tornado or straight-line winds that hit the park.

The Oklahoma Department of Emergency Management said it had reports of nine people taken to hospitals. McKelvey said he believed at least 15 were hurt.

Tornadoes were seen elsewhere in Oklahoma, as well as in Arkansas.
