EF0 tornado, Nogal, Arkansas, June 18, 2023

This EF0 tornado ran 0.2 miles across Perry County on June 18, 2023, touching down at 2:12 AM CDT and reaching 60 yards wide. It killed nobody.

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

6 damage points were recorded along this path by NWS LZK, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

  • Small storage shed lifted and blown to the north with other damage facing west. Cyclonic damage shedding.
  • Small chicken coop blown apart and into window of nearby manufactured home.
  • Small portion of roof decking blown off home, barn in backyard has a little less than half of roof missing.
  • Carport blown sideways, but still attached. Tree damage continues off into the distance ?

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

A cold front moving across Oklahoma toward Arkansas interacted with a stalled front across southern Arkansas. Strong to severe storms were triggered along the boundary and the setup along the cold front prompted the development of clusters of thunderstorms which produced damaging winds and multiple tornadoes.

This tornado started north of Highway 60 near the Perry/Faulkner County line. Visible damage started between Fox Lane and Elm Lane ending near Ferry Boat Road. Damage was observed to the roof of small outbuildings and homes. A chicken coop was blown apart with a portion of the chicken coop being blown into the window of a manufactured home. A carport was blown sideways, but remained attached. Additionally observed was damage to several trees. This tornado dissipated shortly before crossing the Arkansas River between Perry County and Faulkner County; however, the tornado never crossed into Faulkner County. This tornado had estimated winds of 85 mph and was rated EF-0.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 06:03 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.
