EF1 tornado, Scottsboro to Rosalie, Alabama, June 10, 2014

From Scottsboro to Rosalie, this EF1 tornado ran 8.4 miles across Jackson County on June 10, 2014, touching down at 1:44 PM CDT and reaching 300 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 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

92 damage points were recorded along this path by NWS HUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 110 mph.

  • unit did not appear anchored to the ground in any way
  • Bradford Pear trunks/large branches
  • large branches fell onto house
  • poorly-constructed barn completely destroyed

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

Severe thunderstorms developed during the midday hours. One supercell developed ahead of a line of thunderstorms producing a brief tornado in Jackson County before merging with the line. The line also produced significant wind damage in northeast Alabama.

A tornado touched down in a neighborhood just north of the Jackson County Park, near Byron Road. Several trees and branches were snapped as it skipped through the neighborhood. It moved northeast to the K and K trailer Park just south of Highway 35, where it damaged a metal shed, downed multiple trees, and pushed two mobile homes (not anchored) off their foundations.||As the tornado tracked northeast of Highway 35, it intensified upon reaching Barbee Road. Here, it toppled more trees, completely destroyed a small barn, and snapped 4 or 5 wooden power poles. Tree damage became more consistent and widespread as the tornado continued northeast. The most significant damage occurred along County Road 33 just south of Ruby Johnson Drive. At this location, hundreds of softwood and hardwood trees were snapped, including many very large trees. Additional minor structural damage to roofing occurred to homes along Ruby Johnson Drive, and more trees along Belle Drive were snapped and uprooted.||The tornado continued to snap trees and wooden power poles as it tracked northeast, reaching the grounds of the Bellefonte TVA Facility. Here, it snapped trees in at least three separate places on the west side of the complex. The tornado appears to have lifted just beyond the Bellefonte Facility.

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 16:21 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.
