F2 tornado, Erie to Hiattville, Kansas, April 19, 2000

From Erie to Hiattville, this F2 tornado ran 25.0 miles across Neosho, Crawford and Bourbon counties on April 19, 2000, touching down at 8:20 PM CDT and reaching 280 yards wide. It killed nobody and injured 3, and did $2.0 million of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 mphthis tornado

    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. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 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 F2 tornado entered western Crawford County about 3 miles south of Walnut and moved through the northwest portion of the county. The damage path was intermittent and about 200 yards wide. The tornado stayed mainly over rural areas and uprooted trees and damaged or destroyed 3 homes and several outbuildings. The tornado exited the county just east of Hepler and moved into southern Bourbon County.

An F2 tornado crossed the Bourbon and Crawford County line 4 miles southwest of Hiattville and lifted about 2 miles southwest of Hiattville. The path was intermittent and stayed over rural areas.

Forming at 1920 CST 6 miles southwest of Erie, the tornado moved northeast around 35 mph passing just south of Erie at 1931 CST. F2 intensity for much of it's track, the tornado injured 3 people on the southern periphery of Erie as it destroyed or heavily damaged 12 homes, several mobile homes, as well as a few trees. This tornado then crossed into Crawford county.

The warnings

1 minute of warning. NWS ICT issued a tornado warning for this county at 01:19 UTC, 1 minute before the tornado touched down, in force until 02:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Moderate Risk. The outlook in force was issued at 01:09 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.
