What F1 means. This tornado was rated on Fujita’s original scale, used until 2007. F1 meant moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken; the scale paired it with winds of 73–112 mph, figures later judged too high, especially toward the top of the scale, and revised downward in the Enhanced Fujita scale. Ratings then, as now, came from the damage.

What the National Weather Service wrote

A damage assessment conducted by the Wilkes County Emergency Management Director indicated that an F1 tornado, briefly at the high end of the F1 scale, touched down just south of Tignall near Georgia Highway 17 and continued north from six to seven miles along or just west of Georgia Highway 17 to just north of Norman. The path width of the tornado was mostly between 100 and 200 yards, but briefly was up to 500 yards wide between Mallorysville and Georgia Highway 17. The tornado was believed to have been on the ground from 70 to 80 percent of the time along its path. Large trees were uprooted on six single-family dwellings in the Tignall area and several other dwellings were damaged in Norman. All together 23 structures sustained damage from the tornado, ranging from very minor to major. Numerous trees and power lines were blown down, twisted, or uprooted along the path, many causing additional damage to farm fences along the way. A large communications tower was also destroyed. Georgia Highway 17 was blocked in two places along the path by downed trees and three county dirt roads were also blocked along the path. At least 1000 residents in the area lost power and phone service during the event.

Began near Tignall (34.2333, -84.3667).
