A tornado touched down approximately 0.3 miles west of the intersection of Zelner Road and Ripley Road in southern Limestone County. Upon touchdown the tornado produced tree damage. Tracking to the northeast, the tornado produced damage to a metal barn roof along Bell Road, snapped a tree at the base, and uplifted an attached roof of a porch on a small home. Farther to the northeast, the tornado produced mainly roof and window damage in a mobile home park along the west side of Blackburn Road. On Ham Road, more extensive damage was found to a mobile home, which was pushed back about six feet, detaching it from an awning and cement parking pad. This mobile home was anchored to concrete pads that were sitting on gravel, but the mobile home was left largely intact. The tornado continued to snap trees across Evans Road and Reid Road. As the tornado approached U.S. Highway 72, it produced significant damage to a metal-sided outbuilding, while producing mainly roof and siding damage to a couple of metal building systems on the south side of U.S. Highway 72. The tornado produced damage to a couple of metal signs at a gas station located along the north side of U.S. Highway 72 at the intersection of W. Washington Street. Along W. Washington Street, tree damage continued, with some trees uprooted, including a tree that fell on a vehicle. At the intersection of W. Glenn Valley Drive and W. Washington Road, a large tree branch fell, partly on a house. The tornado appeared to lift near this point, with some minor tree damage farther to the northeast in western portions of Athens.
