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 mph
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 mphthis tornado
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
17 damage points were recorded along this path by NWS JAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 120 mph.
- Airport roof blown to this location
- Tin roof over shingles removed completely, front poarch removed.
- Leg injury transported to hospital and released.
- Travel trailer in parts of an outbuilding all blown together into a large pile travel trailer is totally destroyed rated at 120 mph in somewhat because of other damage in vicinity

What the Weather Service recorded
High moisture content and the entire area in the warm sector ahead of an approaching pre-frontal squall line produced strong to severe storms and a couple of tornadoes.
A strong EF2 tornado tracked west to east parallel to Georgia Highway 82, about 2.5 to 3 miles SW of Nahunta. Touchdown was near Santa Fe Road. Extensive mobile home damage and tree damage occurred. Some homes were flattened, blown off of their foundations and completely destroyed. One mobile home was blown off of its foundation and launched into the nearby forest resulting in its total destruction along Matthews Cir. A large section of a roof was removed on a home at Matthews Circle. Additional mobile home and tree damage occurred near Long Lake Road and Buffalo Creek Dr.

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.
