F1 tornado, Estero, Florida, January 24, 2000

This F1 tornado ran 2.5 miles across Lee County on January 24, 2000, touching down at 3:29 AM EST and reaching 70 yards wide. It killed nobody, and did $500,000 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 mphthis tornado

    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

A tornado (F1) touched down approximately one mile southwest of Corkscrew road on Lazy D Farms road where it downed a few trees, caused minor damage to a weathered mobile home, slightly damaged two vehicles and killed two cows. The tornado continued northeast where it caused minor damage to three planes and a recreational vehicle in a hanger on Corkscrew Trace road.The tornado crossed Corkscrew road and caused moderate damage to a 3000 gallon water tank on the north side of the road. The water tank was moved nearly a thousand yards by the tornadic wind. The tornado proceeded northeast and caused minor to moderate damage to a couple of pole barns and destroyed a storage shed along Katydid Lane.The tornado caused minor to moderate damage to a few weathered mobile homes, pole barns and sheds along Wildcat road before it lifted and dissipated.A total of eight homes, four pole barns, four storage sheds, several cars, an airplane hanger and several trees, were damaged by the F1 tornado.

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 Slight Risk. The outlook in force was issued at 05:51 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.
