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.

What the Weather Service recorded

Hurricane Helene made landfall as a Category 4 hurricane with maximum sustained winds of 140 mph and a minimum central pressure of 938 mb (27.70 inches) at about 11:10 PM EDT on Thursday, September 26th, in Taylor County Florida just east of the Aucilla River. Helene quickly moved inland across Taylor and Madison Counties before moving into Lowndes County in South Central Georgia. The hurricane produced a devastating storm surge along the coast of Apalachee Bay, exceeding 15 feet above normally dry ground in some locations. A large area of damaging winds extended from the Big Bend coast well-inland into Georgia along the I-75 corridor, causing significant damage. Wind gusts of at least 90 to 100 mph spread inland through Taylor, Madison, Lafayette Counties in Florida, and into Lowndes County in Georgia. Widespread power outages, structural damage, and severe tree damage occurred throughout this area. Significant rainfall also fell with the hurricane, with a maximum of 12 to 14 inches falling west of Tallahassee in the Apalachicola River Basin. Based on preliminary damage assessments conducted by the Georgia Department of Agriculture, the Georgia Forestry Commission, and the University of Georgia, Hurricane Helene left behind an estimated $6.46 billion in damage to Georgia���s agriculture and forestry industries, more than three times the damage from Hurricane Michael in 2018.

The Georgia Highway Patrol reported a brief tornado touchdown with no damage.

The forecast that day

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 19:55 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.
