EF1 tornado, Bayshore Manor to Suncoast Estates, Florida, June 8, 2008

From Bayshore Manor to Suncoast Estates, this EF1 tornado ran 5.3 miles across Lee County on June 8, 2008, touching down at 4:55 PM EDT and reaching 30 yards wide. It killed nobody and injured 1, and did $100,000 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 mph

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

  2. EF186 to 110 mphthis tornado

    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

High pressure was ridging across the area with the ridge axis in place just to the north of the state. This kept deep east to southeasterly winds in place over the area and allowed a weak west coast sea breeze to develop near the coast.

Fourty four mobile homes had minor damage to roofs, carports and lanais. Ten mobile homes had moderate damage to roofs and portions of walls. One un-anchored single-wide mobile home was pushed 5 feet from its original position, with the roof blown off and exterior walls partially collapsed. One double-wide mobile home had complete structural failure of a well-constructed outer wall and roof section. Most of the damage was in the high-end EF0 range, with a small pocket of low-end EF1 damage. Wind speeds were estimated between 75-100mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 20:06 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.
