EF1 tornado, Boydville to Akridge, Georgia, February 24, 2016

From Boydville to Akridge, this EF1 tornado ran 12.8 miles across Grady County on February 24, 2016, touching down at 2:45 AM EST and reaching 400 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 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    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

38 damage points were recorded along this path by NWS TAE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 94 mph.

  • Multiple pine trees snapped.
  • Single tree snapped. Southern edge.
  • Center pivot irrigation blown over.
  • Several pecan trees uprooted.

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

An unusually strong upper level trough and area of low pressure moved across the southeast states during the Feb 23-24 period, bringing with it numerous reports of wind damage and tornadoes. The low level jet was particularly strong with very strong 0-1 km shear values in excess of 60 knots. The 0-1 km helicity values were in excess of 1000 m2/s2 in some areas with CAPE values around 500 j/kg. There were a total of 11 tornadoes across southeast Alabama and southwest Georgia, including 9 EF1 tornadoes and 2 EF0 tornadoes.

The tornado touched down southeast of Whigham and traveled northeast, crossing Highway 84 between Whigham and Cairo. The tornado lifted northeast of Cairo. The bulk of the damage was to trees and power lines with some minor damage to a few homes, mainly caused by falling trees. The strongest winds were likely along Providence Road where multiple trees were snapped at various levels. In addition, a partially strapped mobile home was moved from its foundation just north of Cairo. Six people were inside the mobile home, and nobody was injured. This tornado was rated EF1 with max winds estimated at 90 mph. Damage cost was estimated.

The forecast that day

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 06:43 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.
