EF3 tornado, Liberty Mitchell Arp to Gashland, Missouri, May 2, 2008

From Liberty Mitchell Arp to Gashland, this EF3 tornado ran 0.9 miles across Clay County on May 2, 2008, touching down at 1:56 AM CDT and reaching 75 yards wide. It killed nobody, and did $4.0 million 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 mph

    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 mphthis tornado

    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

An early morning line of storms developed across south central Kansas. This line of storms, developed into a Bow Echo, which raced northeast at speeds in excess of 50 mph, into the greater Kansas City metropolitan area and surrounding communities, early on the morning of May 2, 2008. The Bow Echo generated hurricane force winds, which brought widespread wind damage, to areas from Olathe Kansas, northeast through Kansas City, to Brookfield in north central Missouri. As the Bow Echo moved through Kansas City, it spun up a couple of tornadoes along the apex, or nose, of its leading edge. One EF3 tornado moved across the north side of Gladstone, while the other EF2 tornado moved through an area just northwest of Liberty. However, most of the damage was due to the strong straight line winds, that were also occurring along the apex of the Bow Echo. Gladstone reported 20 homes destroyed, 280 homes with damage, and 19 businesses damaged. North Kansas City had 4 homes destroyed, and 117 damaged. Independence had 13 homes and two businesses badly damaged. Six people were injured and damage was in the millions of dollars.

A brief EF3 tornado developed along the apex of a bow echo, and touched down northwest of Liberty at 12:56 am CST. The tornado tracked east-northeast for nearly one mile before dissipating at 1:00 am. Four homes were destroyed and 117 suffered damage.

An EF2 tornado developed along a bow echo and touched down at 1:03 am in Gladstone. It then traveled northeast and dissipated at 1:08 am.|Numerous homes and businesses suffered damage or total loss.

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

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.
