EF1 tornado, Cabot, Arkansas, September 13, 2008

This EF1 tornado ran 0.7 miles across Lonoke County on September 13, 2008, touching down at 5:57 PM CDT and reaching 100 yards wide. It killed nobody, and did $300,000 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

Tropical Storm Ike moved into Arkansas on the evening of the 13th. By mid evening of the 13th, Ike was located in western Arkansas. Ike weakened to a tropical depression during the wee hours of the 14th, when it was located about 105 miles west-northwest of Little Rock. Ike exited northern Arkansas before sunrise on the 14th. In the Little Rock County Warning Area, wind gusts of 35 to 45 mph were common, and some gusts in the northern part of the state exceeded 50 mph. The strongest gusts measured were 67 mph at the Izard County Fairgrounds in Melbourne and 61 mph at the Newport airport. The strongest sustained wind measured was 46 mph at the Newport airport. Power was knocked out to more than 200,000 electric customers. Wind damage was estimated at just over $30 million. There was one injury due to the winds. The greatest storm total rainfall was 4.60 inches at Big Fork. The lowest barometric pressure was 29.10 inches at Mountain Home. There were seven weak tornadoes, with damage estimated at just over $450,000.

This tornado was spawned by Tropical Storm Ike. The tornado peeled the metal structure off a self-storage warehouse building. Although the items stored in the warehouse were left pretty much in place, heavy rain poured onto them, badly damaging them. The roofs of several apartment buildings were damaged. In some cases, holes in the roof were large enough to allow rainwater to fall into the apartments. Metal buildings at an abandoned lumber yard had strips to metal torn off and thrown onto neighboring properties. A medical supply company's roof was damaged and bay doors were blown in. The facade of a strip mall was damaged, and business signs at the strip mall were blown out. Fences were blown down, as were power poles, power lines, and several large trees.

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

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 20:00 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.
