F0 tornado, Cleveland, Georgia, July 11, 2005

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.

  1. F040 to 72 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

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

  3. 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.

  4. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. 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.

  7. 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

The White County Emergency Management Director reported that an F0 tornado touched down in the southwest corner of White county near the Hall county line at the Wauka Valley Farms area, then skipped along the ground on a path to the north-northwest for approximately five miles, terminating in the Town Creek Road area of western White county. The tornado path width was determined to be approximately 1/8 to 1/4 mile wide. Considerable damage was reported at the Wauka Valley Farms facility. Hundreds of trees were twisted off, blown over, or uprooted. Two barns were destroyed from downed trees and wind damage. The roof of one barn was found a considerable distance downstream. In addition, wooden two-by-fours were discovered nearly a mile away from the farm. One home sustained room damage and a number of trees and power lines were also down along Town Creek road, approximately five miles west of Cleveland at the end of the damage path area, but the majority of the damage was done in the Wauka Valley Farms area. Overall, in excess of 200 trees were down in the southwest part of the county. The tornado formed on the tail end of a feeder band associated with the remnants of Hurricane Dennis.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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 General Thunderstorms Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:42 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
