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 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

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.

What the Weather Service recorded
A strong spring cold front moved through the tri-state region. A squall line preceded the front with scattered reports of severe weather, including a few tornadoes.
An EF1 tornado touched down in Terrell County. Damage was initially reported along Kirbo Road where there was roof damage to one single family home. Numerous pines in the yard were snapped or uprooted at this residence. Further east on Kirbo Road, additional pine trees were snapped or uprooted. More trees were observed uprooted or snapped along Florida Short Route just to the northeast of Kirbo Road. No structures were damaged in this area. The tornado again snapped or uprooted several trees along Anthony Road. The tornado lifted before reaching US-82. NWS Tallahassee extends our appreciation to Terrell County Emergency Management for their assistance in this damage survey. Max winds were estimated around 90 mph.

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.
