There is at least one storm-related death, and numerous cars are overturned on Interstate 75 after a tornado struck Adairsville, Georgia, the National Weather Service reported.
The twister touched down before noon in the city of about 4,600 located roughly midway between Atlanta and Chattanooga, Tennessee, the weather service reported, adding that two other tornadoes were reported in the region - one in east Lindale, another in southeast Calhoun.
Although you cannot see I-75 itself in the accompanying video, a local TV crew filmed the funnel as it crossed I-75.
According to CNN, there are approximately 100 overturned cars at Exit 306, officials are asking drivers to avoid the area.
