EF1 tornado, Brooksville to Enon, Alabama, July 14, 2015

From Brooksville to Enon, this EF1 tornado ran 4.9 miles across Morgan and Cullman counties on July 14, 2015, touching down at 6:59 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

24 damage points were recorded along this path by NWS HUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 90 mph.

  • pine tree snapped. another tree toppled toward wnw
  • Evidence of twisting of large snapped limb.
  • multiple limbs down facing ese
  • dead tree limb down on home

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 quasi-linear convective system (QLCS) dropped southward into the Tennessee Valley during the afternoon and evening hours. The airmass was very unstable, and despite low to moderate low to mid level wind shear, multiple swaths of damaging winds occurred. Within these pockets of winds, a few weak and mostly short-lived tornadoes developed. The most concentrated wind and tornado damage occurred in portions of Lauderdale, Colbert, and Lawrence Counties including the Shoals region of Florence, Sheffield, Muscle Shoals, Town Creek and Courtland. Other short-lived tornadoes occurred in Madison, Morgan and Cullman Counties. Unfortunately, one person was killed by a falling tree near West Point in Cullman County.

A tornado developed along Bethel Road about two miles south of Priceville. The tornado tracked southeast up a ridge into a residential area along Spring Valley Road and Spring Valley Trail. Wind speeds in the tornado ranged from 60 to 80 mph snapping numerous large tree limbs. At least one tall hardwood tree was partially uprooted while another was fully uprooted although it had a rotted base. A large portion of a tree was toppled onto a home along River Valley Trail causing damage to siding, gutters and the rooftop. The tornado then lifted upon reaching Shoal Creek Road.

A tornado touched down along County Road 55 near the intersection of Coyote Hollow Drive. The tornado snapped large limbs and knocked down a moderate sized tree onto a home. The tornado skipped a path southeast along County Road 55 atop Cook Gap Mountain. The most concentrated and intense damage incurred by this tornado was located at residences along and adjacent to the intersection of County Road 55 and Union Hill Church Road. A few large trees and limbs were snapped. A few but very large trees were completely uprooted in this general area. Peak wind speeds are estimated to be 90 to 95 mph in these instances. The tornado then skipped along a path a bit more south-southeast crossing Maddox Road snapping large limbs of trees. The tornado then crossed into Cullman County.

A tornado continued its path from Morgan County into Cullman County at Eva Road at County Road 1459 where a tree was snapped at its trunk and where a home lost considerable amounts of siding on the west facing side.

The Storm Prediction Center had this point in a Slight 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.
