EF0 tornado, Ft Myers Beach to Cape Coral, Florida, September 16, 2007

From Ft Myers Beach to Cape Coral, this EF0 tornado ran 0.1 miles across Lee County on September 16, 2007, touching down at 6:25 PM EDT and reaching 30 yards wide. It killed nobody, and did $110,000 of property damage.

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.

  1. EF065 to 85 mphthis tornado

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

  2. EF186 to 110 mph

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

  3. EF2111 to 135 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. 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.

  5. EF4166 to 200 mph

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

  6. 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.

  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 waterspout and at least two tornadoes formed along the west Florida coast sea breeze front in the Fort Myers area.

A waterspout moved onshore near Estero Boulevard and Canal Street as a tornado and damaged the roof of a resort hotel and a nearby Tiki bar.

Thunderstorms continued to develop northward along the sea breeze front and produced a tornado that traveled due north from near the intersection of Rose Garden and and El Dorado Parkway West to near Skyline Boulevard and Veterans memorial Parkway. The damage path was less than the size of a single family home for most of the track and the average wind speed based on the damage was 65-75 MPH. The EF1 damage was of a home nearly cut in half by the tornado with wind speeds estimated at 105 MPH. The lower than expected wind estimate was a result of older building codes and the roof blowout occurred as a result of a large picture window being blown in. About 138 homes were damaged. Six homes received moderate damage and one home was destroyed. The tornado snapped several power poles and damaged numerous fences, sheds and trees. Several vehicles and boats were flipped over. There was one injury as a gentleman looked outside to see the tornado and was struck by debris. Thirty people were displaced from their homes. Damage estimates were based on a survey completed by Cape Coral Emergency Management.

The warnings

0 minutes of warning. NWS TBW issued a tornado warning for this county at 22:25 UTC, 0 minutes before the tornado touched down, in force until 22:45 UTC.

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. The outlook in force was issued at 20:03 UTC.

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.
