EF0 tornado, Clewiston Airglades, Florida, October 9, 2024

This EF0 tornado ran 1.3 miles across Hendry County on October 9, 2024, touching down at 2:15 PM EDT and reaching 50 yards wide. It killed nobody, and did $1,000 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.

The damage survey

8 damage points were recorded along this path by NWS MFL, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 107 mph.

  • Chaser on Evercane road reports multi vortex tornado on the ground.
  • Video at 959am of a large tornado on the ground with debris aloft.
  • Trees snapped across Sam Jones Trail from FPL solar farm
  • Bent solar panels at the FPL solar facility

What the Weather Service recorded

Hurricane Milton became a Category 5 hurricane in the southwestern Gulf of Mexico on Monday, October 7th about 735 miles SW of Tampa while moving east-southeast, then turned east and northeast on Tuesday, October 8th while maintaining Category 4 and 5 strength. Milton's maximum winds decreased as it approached the Florida peninsula on Wednesday, October 9th, and made landfall near Siesta Key as a Category 3 hurricane with maximum sustained winds of 120 mph and a minimum central pressure of 954 mb. The outer circulation of Milton began affecting South Florida late on October 8th, with sustained tropical storm force winds spreading across much of the region through the early morning hours of Thursday, October 10th. ||A total of 15 tornadoes were recorded across South Florida on Wednesday, October 9th, two of these reaching EF-3 on the Enhanced Fujita Scale.||Moderate to major coastal flooding occurred most of the Collier County coast, mainly on October 9th from late morning through the overnight. Inundation above ground was in the 2-4 foot range across much of the beach and bayfront locations across the county, with a maximum estimated inundation of near 5 feet in Chokoloskee. The tide level at the NOS gauge in Naples Bay near the city dock reached 5.08 ft above Mean Higher High Water (MHHW). ||A total of 2,900 people evacuated to refuge centers in Collier County, and about 1,000 in Palm Beach County.||All of the associated effects of Milton in South Florida resulted in 10 injuries and at least $361 million in property damage. The 15 tornadoes associated with Milton resulted in 10 injuries and at least $81 million in damage, mainly in Palm Beach and Glades counties.

This is one of three brief tornadoes associated with a cluster of three supercells across the interior Hendry County in the early afternoon. The tornado was rated as an EF-0 with estimated an maximum winds near 65 mph. Time and path width are estimated based on radar velocity couplet. Damage amount is estimated.

This is one of three brief tornadoes associated with a cluster of three supercells across the interior Hendry County in the early afternoon. The tornado was rated as an EF-1 with estimated an maximum winds near 102 mph. Damage to a large utility pole was noted along Wilson Way, to the west of County Road 833 during the storm survey. Time and path width are estimated based on radar velocity couplet. Damage amount is estimated.

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 16:23 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.
