EF0 tornado, Rocky Mt, North Carolina, August 8, 2024

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

Tropical Depression Debby slowly made its way through Florida, off the South Carolina coast, then back inland through the western Piedmont of North Carolina during the evening hours of 8 August 2024. Ahead of the storm, numerous feeder bands brought periods of heavy rain to central North Carolina, resulting in widespread 4-6 inch rainfall amounts across the western Piedmont, with higher amounts to the east. In addition, numerous tornadoes occurred with this event, with one on 7 August and an additional 6 on 8 August including a rare EF-3 tropical cyclone tornado.

A tornado briefly touched down in a agriculture field along Springfield Road. Several small softwood trees were snapped and uprooted. Several crop damage swirls were also seen throughout the field. A tornado debris signature was noted on radar at the time.

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

The warnings

1 minute of warning. NWS RAH issued a tornado warning for this county at 21:03 UTC, 1 minute before the tornado touched down, in force until 21:30 UTC.

The county was under a tornado watch, issued at 16:55 UTC and running to 22:40 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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:32 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
