EF1 tornado, Socapatoy to Hackneyville, Alabama, February 17, 2008

From Socapatoy to Hackneyville, this EF1 tornado ran 10.8 miles across Coosa and Tallapoosa counties on February 17, 2008, touching down at 1:42 PM CST and reaching 100 yards wide. It killed nobody, and did $105,000 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.

What the Weather Service recorded

A broken squall line, sparked by an advancing cold front and strong upper level storm, caused severe thunderstorms and tornadoes across Central Alabama.

The tornado touched down along US Highway 280 near the Bradford Community. The tornado moved northeastward and crossed AL-9, before crossing into Tallapoosa County east of Goodwater. The most significant damage occurred in Coosa County, near the intersection of CR-77 and AL-9. At least 6 homes suffered varying degrees of damage, and at least three automobiles were heavily damaged by fallen trees.

The tornado touched down near Pearson Chapel Road, north of Barnett Road. It then traveled northeastward and ended just north of Hackneyville before it crossed County Road 5. A few homes suffered minor roof damage and a few trees were either snapped off or lost some limbs.

The tornado that touched in Coosa County moved into the northeastern portion of Tallapoosa County, between Goodwater and Hackneyville. It then continued to move northeast, crossing AL-63, before lifting just before the Tallapoosa and Clay County line. In Tallapoosa County, most of the damage was limited to broken limbs and snapped softwood trees.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:17 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
