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

46 damage points were recorded along this path by NWS MOB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 120 mph.

  • Power lines snapped at the base a few feet from the ground.
  • Several power poles snapped at the base. Metal roofing from a small barn lifted and blown between 100-200 yards. Debris blown and laying in the same direction.
  • More power lines snapped. Large tree uprooted.
  • 2 or 3 power poles snapped or leaning in a divergent pattern.

What the Weather Service recorded

Two storm complexes moved across southeastern Mississippi, southwestern Alabama, and into the Florida Panhandle during the early morning hours of 5/10 producing destructive straight-line winds and multiple tornadoes.

After thorough review of available high resolution Planet satellite imagery, it was determined the EF2 tornado that ground survey crew assessed in Munson began much earlier. The tornado began south of Highway 4 to the west of Berrydale where a persistent narrow path of significant tree damage was evident on Planet imagery. This narrow swath continued to be evident in the forest south of Berrydale near Highway 4. Once the tornado passed Highway 87 N it likely intensified significantly as deforestation extent became significant and the tornado turned more to the southeast. After its southeast jog it turned back to the east reaching Highway 4 where ground survey crew initially assessed the tornado. The tornado continued along State Highway 4 about 3 miles west northwest of Munson where pine trees were snapped, and power lines were downed in a convergent pattern. The tornado peaked in intensity at an estimated 115 mph (EF2) over Munson where numerous pine trees were snapped in a convergent pattern in a swath about 450 yards wide. The tornado then took a slight jog to the east-southeast as it essentially paralleled State Highway 4 east of Munson with numerous pine and oak trees snapped on both sides of the road. As the tornado continued east of Munson across the Blackwater River State Forest, it became a broader multivortex with several prominent sub-vortices rotating about the main tornado vortex. Snaps continued into Okaloosa County Florida where the tornado is estimated to have lifted to the northwest of Baker between Highway 4 West and Sherman Kennedy Road. This survey was able to be completed with the assistance of NASA SPoRT, NASAMSFC, NASA CSDA and the NASA Disasters Program providing high resolution Planet satellite imagery. Without the availability of this remote sensing imagery, the true path length, width, and track of this tornado would not have been able to be determined.

A new EF-U tornado has been discovered via high resolution Planet satellite imagery from the May 10th tornado event. A radar tornado debris signature was present which necessitated the review of available satellite imagery to confirm the existence of this tornado. The tornado began near Highway 89 just northeast of Chumuckla and tracked east-southeast towards Highway 87 N. The tornado likely lifted just prior to the highway as the damage path evident on satellite imagery ends just prior to the highway. Once higher resolution imagery becomes available, the tornado intensity may be able to be assessed.

A new EF-U tornado has been discovered via high resolution Planet satellite imagery from the May 10th tornado event. A radar tornado debris signature was present which necessitated the review of available satellite imagery to confirm the existence of this tornado. The tornado began east of Paul Barnes Road and solely remained in dense forest, tracking southeast of three quarters of a mile. The tornado lifted midway between Paul Barnes Road and Three Notch Trail.

A radar tornado debris signature was present which necessitated the review of available satellite imagery to confirm the existence of this tornado. The tornado began north of Red Rock Road and just east of Will Sexton Road in forested areas. The tornado tracked east-southeast eventually crossing Red Rock Road at the intersection of Pleasant Home Church Road and Bryant Bridge Road. The tornado lifted shortly after this point. Once higher resolution imagery becomes available, the tornado intensity may be able to be assessed.||This survey was able to be completed with the assistance of NASA SPoRT, NASAMSFC, NASA CSDA and the NASA Disasters Program providing high resolution Planet satellite imagery.

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.
