The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 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.
F3158 to 206 mphthis tornado
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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.

What the Weather Service recorded
Tornado first touched down just northeast of Pembroke and then crossed I-16 at the Olive Branch Road overpass (about 2 miles west of exit 29) then continued northeast. Significant damage occurred in the Olive Branch Rd. area and also just north of Blitchton, where a 38 year-old female and a 41 year old male were killed along with 15 injured. There were seventy-four (74) homes and other buildiings damaged, with fourteen of those destroyed (6 mobile homes, two frame houses, two brick homes, and four other buildings. Numerous trees were uprooted or snapped off 10 to 15 feet above the ground.
The Bryan County tornado crossed the county line and weakened as it moved into a less populated area. Once the tornado moved east of GA State Road 17, it lifted. There were no further reports of damage or touchdowns from the parent supercell until the F1 touchdown reported just west of Hardeeville, S.C., which is approximately 12 miles from the last report of damage in Effingham County, Georgia. There were 40 homes damaged along GA 17, about 5 miles south of Guyton. Six of these were mobile homes that were destroyed. Numerous trees were uprooted or snapped off 10 to 15 feet above the ground.

The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 Slight Risk. The outlook in force was issued at 11:00 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.
