EF0 tornado, Fruitland Park to Lady Lake, Florida, September 1, 2016

From Fruitland Park to Lady Lake, this EF0 tornado ran 4.3 miles across Lake County on September 1, 2016, touching down at 8:40 PM EDT and reaching 250 yards wide. It killed nobody, and did $22,000 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

As Hurricane Hermine approached a Gulf of Mexico landfall along the Florida Big Bend, a strong outer rainband moved into the central Florida interior from the eastern Gulf. Within the rainband, several shallow mesocyclones become evident on radar across western Orange County and northwest Lake County. Two EF0 tornadoes were confirmed, as well as areas of straight-line wind damage.

Emergency Management officials provided detailed wind damage reports which occurred along a 4.35 mile long south-to-north path from Fruitland Park to Lady Lake, parallel to and just west of U.S. Highway 441. The damage consisted mainly of downed trees, branches and powerlines, although two homes in Lady Lake sustained structural damage due to falling trees. The most significant damage occurred on the east side of the tornado track, due to the rapid storm motion of 60 mph. The discontinuous damage path began near the College Avenue and W Miller Street in Fruitland Park and ended in Lady Lake, about midway between the Recreation Plantation RV Resort and Highway 441. A review of all available data suggests that the wind damage was likely the result of a EF-0 tornado (winds estimated 70-75 mph). Isolated tree damage south and north of the tornado track was likely due to strong straight-line winds associated with the cell. DI2, DOD1, EXP; DI27, DOD2, EXP; DI27, DOD3, LB.

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, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:41 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.
