EF0 tornado, Gulfport to Wool Market, Mississippi, June 24, 2020

From Gulfport to Wool Market, this EF0 tornado ran 3.0 miles across Harrison County on June 24, 2020, touching down at 12:26 PM CDT and reaching 50 yards wide. It killed nobody, and did $20,000 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

57 damage points were recorded along this path by NWS LIX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

  • Several slash pines snapped about midway.
  • Windward side (S) of structure displaced inward. Roof joist lifted from column fasteners.
  • Partial removal of roofing material from single story well constructed home.
  • Middle portion of roof on a single family brick home sustained roof loss.

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

What the Weather Service recorded

Two mesoscale cycloncic vortex systems (MCVs) produced several severe thunderstorms across the area from early morning through the mid afternoon hours of Wednesday June 24, 2020. There were several tornadoes reported with these severe thunderstorms as they moved across the area. The most significant tornadoes impacted the Baton Rouge area, the Salem area of Walthall County, and the Mississippi Gulf Coast.

A National Weather Service Damage Assessment Team has surveyed the storm damage in Gulfport, MS. It has been determined the damage was the result of a tornado. The tornado has been rated an EF-0 on the Enhanced Fujita Scale. Damage estimates were consistent with winds of 65 mph.||Several large hardwood tree limbs snapped and minor roof damage to several homes from US Highway 90 near the aquarium to the CSX railway near Henderson Avenue.

A National Weather Service Damage Assessment Team has surveyed the storm damage in Harrison County, MS north of D'Iberville. It has been determined the damage was the result of a tornado. The tornado has been rated an EF-1 on the Enhanced Fujita Scale. Damage estimates were consistent with winds of 105 mph.||Small populated community along Old Highway 15 had a couple of homes with roof damage. Many trees were violently twisted. A power pole was snapped at the base.

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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 16:32 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.
