F3 tornado, Mc Coy, Texas, June 9, 2005

This F3 tornado ran 15.0 miles across Hale and Floyd counties on June 9, 2005, touching down at 6:25 PM CDT and reaching 900 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 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 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. F3158 to 206 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. 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

The National Weather Service in Lubbock, TX conducted a damage survey in the vicinity of McCoy, TX in Floyd county. The tornado was a long-lived occurrence stretching from the Petersburg area in southeast Hale county across portions of southwest and south-central Floyd county. Significant damage resulted from a tornado impacting a grain elevator about 5 miles east of Petersburg/5 miles west of McCoy.The tornado destroyed the grain elevator, numerous power poles and center pivot irrigation systems across the area along and either side of FM 54. Numerous homes sustained roof and structural damage. One home sustained extensive roof damage as tornadic winds breached the garage and moved a pickup truck about ten inches in the driveway. The damage surveyed indicated the tornadic circulation was multi-vortex in nature. Extensive video of the tornado was captured by media and storm chasers depicting a very large, wedge tornado appearance. Another residence sustained extensive damage with a pickup truck thrown over 1/2 mile from the driveway into a field behind the home. The truck was lifted and carried through the air to the field and sustained only glass damage. The Fujita-rating for this long-lived tornado was rated F-3 based on the movement and condition of the vehicle, however the majority of the damage was rated in the F-1 and F-2 categories.

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 21:04 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.
