The most significant tornado damage occurred on Salacoa Road near Beasley Gap, where the tornado damage was classified as F2. The damage path was approximately 627 yards wide at its widest point, but the tornadic portion of this damage was limited to around 100 yards wide.

 Brief Description: The tornado that originated in Cherokee county near Beasley Gap, continued into and across Pickens county. Once again, the National Weather Service disaster survey team determined that this was a multi-segmented tornado, with much of the damage along the path caused by straight line winds of at least 70 mph. The tornado entered the county southwest of Cagle, then continued on to just north of Tate roughly paralleling Georgia Highway 108, then turned more eastward along Georgia Highway 53 to near Marblehill, through the Big Canoe golf course and recreation area, then east of Big Canoe into extreme western Dawson county. There was definite evidence of F2 tornadic damage just north of Tate where winds were estimated in the 113 to 157 mph range. Some of the hardest hit areas included homes on Pleasant Union Road near the Cherokee county border; the Mountain Lakes Estates area, where several homes suffered extensive damage; the Bethany-Salem district where at least 56 structures were damaged or destroyed; Refuge Road near Tate, the town suffering some of the greatest damage where several homes and business were destroyed; the Big Canoe area near the Dawson county border, where several homes were damaged and the tennis center suffered extensive damage. All together, a total of 26 structures, mostly residential homes were destroyed, 142 structures were partially damaged, 2 businesses were destroyed, and 14 vehicles were totally destroyed. In addition, ten people were injured, primarily in damaged homes or trapped in vehicles on which trees fell. One of the businesses destroyed was the popular Davis's Barbeque on Georgia Highway 108. The restaurant was completely blown away, including the 20-foot white columns that stood in front of the restaurant. Three of the injuries in the county occurred in new mobile homes behind the Barbeque restaurant when their homes were flattened by the winds and other debris from the restaurant. One of the children injured, a 4-year old girl, was found by a nearby pond. The Refuge Baptist Church suffered extensive damage and was left in shambles. The historic Big Canoe chapel was also among the structures suffering damage. The steeple and all of the windows were lost from the church along with other structural damage to both the exterior and interior walls. Numerous trees were uprooted and many power lines were damaged along the path. Thirty people had to be put up in shelters and at least 6000 people were left without power for an extended period.

 Brief Description: The Dawson county Emergency Management Director reported that the tornado that originated in Cherokee county and traveled across Pickens county, entered Dawson county in the Big Canoe area and continued to just east-northeast of the Big Canoe area before dissipating. Two double-wide mobile homes were completely destroyed just east of the Big Canoe area as large trees fell on the structures. While the contents of one were salvagable, those of the other were destroyed. Three injuries occurred at one of these mobile homes as the residents were trapped by the downed trees on the structure. In addition, there were four other homes that received minor damage in the Big Canoe area. Numerous trees and power lines were blown down in the area of the tornado and some roads were temporarily blocked as a result. Dawson county was one of five counties declared in a state of emergency by the governor.
