Clarendon County, SC (WLTX) - The National Weather Service has confirmed a tornado touched down in the Midlands Saturday.
Operators at the Santee Cooper Dam on Lake Marion spotted the tornado over the lake, in an area 10 miles southeast of Manning.
The tornado touched down below the dam. The weather service says the twister uprooted trees.
Trained surveyors determined the tornado was an EF-1 on the Enhanced Fujita Scale, meaning it had winds between 90 and 105 miles an hour.
The storm cell which moved through Clarendon County also produced softball and golfball sized hail. It was part of a larger storm system which spawned dozens of tornadoes and left 45 people dead.
