In Macon County, 5 single family residences and 3 mobile homes were destroyed from 2 miles east of Atlanta to 10 miles northeast of Atlanta. Four single family homes were damaged within this area. Several outbuildings were also damaged or destroyed. Some damage south of the tornado track was likely due to the very intense rear flank downdraft, which storm spotters observed to accompany the storm.
