Days after a powerful tornado caused extensive damage to a high school in Kershaw County, another South Carolina school is cleaning up from a tornado.

Investigators with the National Weather Service determined an EF-1 with winds of 90 mph hit the campus of Loris High School in Horry County, South Carolina Monday.

At 12:44 p.m. Monday, cars in the parking lot were picked up and tossed on top of each other during a strong thunderstorm.

The Wilmington, North Carolina-based National Weather Service storm survey crew determined the damage was caused by a tornado.

They are continuing their investigation to determine how long the tornado was on the ground.
