From Intercession City to Christmas, this F3 tornado ran 28.0 miles across Orange and Osceola counties on February 22, 1998, touching down at 12:40 AM EST and reaching 250 yards wide. It killed 25 people and injured 150, and did $55 million of property damage.

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 mph

    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 mphthis tornado

    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 deadliest tornado of the outbreak was a category F3 that touched down initially one mile south of Intercession City. The tornado moved northeast at 45 mph and ripped through the town of Kissimmee killing 25 people. The hardest hit areas were the Morningside Acres mobile home community and the Ponderosa Recreational Vehicle Park. In all eight people were killed in recreational vehicles, fifteen in mobile homes and one in an automobile. The tornado continued northeast and moved into Orange County six miles north of St. Cloud. One hundred and fifty people were injured and over 1000 structures were damaged or destroyed.

The Kissimmee tornado moved into Orange County southeast of Orlando International Airport as a category F3. The tornado affected rural swampy areas, striking few structures except for lakeside neighborhoods on the shores of Lake Hart and Lake Mary Jane. The tornado lifted as it approached the St. Johns River on the east central border of Orange County in the Tosohatchee State Preserve.

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.
