At first I thought it was just hearsay but this is part of the story from CNN:

The National Weather
Service also reported major structural damage and overturned cars in
downtown Adairsville, where a news crew for CNN affiliate WSB-TV
witnessed a tornado form and touch down Wednesday morning. The tornado
destroyed a home and flipped several cars, the station reported.

The storm caused major
damage on and near Interstate 75, the Georgia Department of
Transportation said. The weather service, citing emergency management
officials, said 100 cars had been overturned near Exit 306 at
Adairsville.
