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

Summary of events of June 13, 1998:During the afternoon and evening four supercell thunderstorms developed near a dryline in western Oklahoma and tracked east into central sections of the state. The most significant storm developed in Washita county at approximately 400 pm CST and intensified as it moved east toward central Oklahoma. This storm produced at least six tornadoes as it tracked from Canadian County across Oklahoma County during the early evening. The most damaging tornado (an F2) touched down in northeast Oklahoma City and crossed Interstate 35 near the Frontier City theme park. Other tornadoes damaged the Oklahoma City Boat Club, portions of The Village and Nichols Hills, the Highland Park neighborhood west of Broadway Extension, and the area near May and Grand Avenues in Oklahoma City. Three weak tornadoes also touched down in open country northwest of El Reno and near Yukon. In addition to damaging tornadoes, the storm produced extensive straight-line wind damage from Lake Hefner, across Nichols Hills and The Village, into northeast Oklahoma County. Winds likely exceeded 100 mph in some areas. There were no fatalities and only 21 relatively minor injuries reported in Oklahoma County. The majority of the injuries were sustained at the Frontier City theme park. Earlier, another supercell thunderstorm produced tornadoes near Longdale in Blaine County and 3 miles southwest of Guthrie. Supercells that tracked across Noble County and northern Cleveland County produced large hail and severe winds, but no tornadoes.See preceding individual Storm Data entries for further details and additional reports.

A tornado touched down briefly in open country. No damage was reported and the tornado was rated F0.

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.
