The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey
5 damage points were recorded along this path by NWS GSP, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

What the Weather Service recorded
A line of thunderstorms moved into northeast Georgia during the late afternoon. An embedded cell within this line produced a weak tornado that tracked across parts of three counties. Some isolated gusty winds were also reported.
NWS storm survey found the path of a weak tornado that touched down north of Starrs Bridge Rd, just west of Johns Bridge Rd. The tornado tracked southeast, crossing Starrs Bridge Rd, Bryant Park Rd, and Campbell Ridge Rd before crossing through the western side of Royston. The tornado passed into Hart County on the south side of Royston. Damage was limited to multiple uprooted trees.
NWS storm survey determined a tornado that touched down in Franklin County crossed into Hart County on the south side of Royston, and continued moving southeast through the western part of the county, essentially paralleling Highway 17. The tornado crossed into Elbert County just west of the highway. Damage remained limited to uprooted trees and large snapped limbs in Hart County.
NWS storm survey found a tornado that began in Franklin County and crossed through western Hart County, moved into Elbert County just west of Highway 17 before lifting. Damage was limited to uprooted trees and snapped tree limbs.

The warnings
10 minutes of warning. NWS GSP issued a tornado warning for this county at 19:41 UTC, 10 minutes before the tornado touched down, in force until 20:30 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 forecast that day
The Storm Prediction Center had this point in a Marginal Risk. The outlook in force was issued at 16:27 UTC.

What this means
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.
