EF1 tornado, Crumptonia to Kings Lndg, Alabama, March 1, 2007

From Crumptonia to Kings Lndg, this EF1 tornado ran 12.2 miles across Dallas County on March 1, 2007, touching down at 12:31 PM CST and reaching 500 yards wide. It killed nobody, and did $250,000 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

15 damage points were recorded along this path by NWS MOB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF4. The highest wind the damage implies is 185 mph.

  • In person aerial survey reveals a couple tree snaps/uproots at this location.
  • Aerial survey reveals nearly all trees snapped with several trees debarked.
  • Several well built homes completely destroyed with slabs swept clean. All trees snapped at the base or uprooted in the vicinity with debarking.
  • Complete destruction of several mobile homes at this location. All trees snapped and/or uprooted here.

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 powerful spring storm system brought an outbreak of tornadoes, damaging winds, and large hail to Central Alabama.

A tornado that had previously caused EF-4 damage in Wilcox County crossed the Wilcox-Dallas county line about 6.4 miles southeast of the town of Alberta. The tornado then tracked northeastward and ended along the Alabama River, east of the Whites Bluff community. The most concentrated damage in Dallas County occurred just south of Five Points along County Road 31 and along County Road 33. Twenty seven homes suffered varying degrees of damage, and two homes were completely destroyed. At least six outbuildings were damaged. Numerous trees and power lines were either snapped off or uprooted along the path.

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

The warnings

7 minutes of warning. NWS BMX issued a tornado warning for this county at 18:24 UTC, 7 minutes before the tornado touched down, in force until 19:15 UTC.

The county was under a tornado watch, issued at 13:31 UTC and running to 01:45 UTC.

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 High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:46 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.
