Unrated tornado, Pine Grove, Florida, August 4, 2025

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 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.

    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

1 damage points were recorded along this path by NWS MLB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU.

  • A brief tornado occurred over northern rural Osceola County on Monday, August 4, 2025 as confirmed by a combination of video evidence from local media partners and data from the National Weather Service Melbourne (KMLB) radar. The tornado developed as a result of numerous low-level boundary collisions. The circulation is estimated to have touched down at approximately 7:14 PM EDT along the southern side of Lake Joel in St. Cloud, near Sungrove Ln and the C-32 Canal. KMLB radar data indicate the circulation, along with a corresponding debris signature, moved east over a densely wooded area before subsequently lifting around 7:22 PM EDT., just west of Storey Bend Rd. Given limited access to the affected area, the track is considered approximate, and an EF-rating cannot be provided at this time. Refinements to the track will be made if additional photographic or video evidence becomes available.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

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 19:52 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.
