The remnants of tropical storm Fay continued to move northeast into central and northern Alabama on the 26th, then finally into eastern Tennessee on the 27th. This was the day when north and central Georgia experienced its maximum effects from tropical storm Fay. The outer rain bands of tropical storm Fay spawned six tornadoes across north and central Georgia during the afternoon and evening hours of the 26th. The majority of these affected northeast and east central Georgia. Three injuries were reported in Jackson county as a result of one of these tornadoes and damage was reported to a shopping center and an elementary school in Hall county. In addition, widespread heavy rain affected much of north and central Georgia with flash flooding reported in several northeast Georgia mountain counties. Storm total rainfall from Fay was as high as seven to eight inches across the northeast Georgia mountain counties of White, Lumpkin, Union, and Towns, as well as in adjacent Hall county. Similar rainfall totals were observed in parts of west central Georgia south and southeast of Columbus, although most of this occurred during the first passage of Fay to the south through the Florida Panhandle.

A survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia and the Hall County Emergency Management Agency confirmed that an EF1 tornado touched down approximately six miles north-northeast of Gainesville, or about 3 miles east-southeast of Murrayville near Mount Vernon Road and tracked on the ground for approximately one mile before lifting. Nearly 200 trees were uprooted or blown down. The downed trees and wind caused damage to approximately 20 homes in the area. The maximum path width of the tornado was about 200 yards. Maximum wind speed in the tornado was estimated to be 90 mph.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 12:55 UTC.

14 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
