Tornado warnings were issued and sirens blared for a time Wednesday night as a pair of storms moved across the area.
A confirmed, “extremely dangerous” tornado was spotted near Sand Springs, moving east at 45 mph, the weather service said.
A mobile home park southwest of that town was “hit very hard,” said Chief Daniel Bradley of the Sand Springs Fire Department. His office was told 24 homes were damaged, some rolled over.
One person died and several people were injured.
The tornado warning includes downtown Tulsa.
“Take cover in a basement or storm shelter now!” the weather service advised those in the storm’s path.
Large, damaging hail the size of baseballs and hurricane-force winds are possible.
A severe thunderstorm watch was in effect for the area until late Wednesday night.
Tornadoes were also reported in the Ozark Mountains of northwestern Arkansas.
