EF1 tornado, Floyd to Bethel, New Mexico, June 12, 2012

From Floyd to Bethel, this EF1 tornado ran 1.1 miles across Roosevelt County on June 12, 2012, touching down at 9:07 PM MDT and reaching 75 yards wide. It killed nobody.

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

A second round of thunderstorms for the day developed over the higher terrain of the northern mountains by the afternoon and then pushed into the eastern plains. Higher surface dewpoint temperatures in the mid 50's to lower 60's over west Texas were advected into southeast and east central New Mexico and acted as fuel for convection throughout the day. Increased moisture and instability with daytime heating continued convection through the late evening hours. Large damaging hail was the primary impact of these storms.

A long track tornadic supercell thunderstorm that developed over far western portions of the Caprock in extreme southeast Guadalupe county produced significant and widespread damage along a path that stretched from over 100 miles from approximately 15 miles north of Fort Sumner to near the New Mexico / Texas state line south of Causey. This was the first of two relatively short tornado damage paths that were surveyed.

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

The warnings

36 minutes of warning. NWS ABQ issued a tornado warning for this county at 02:31 UTC, 36 minutes before the tornado touched down, in force until 03:15 UTC.

The county was under a severe thunderstorm watch, issued at 20:44 UTC and running to 05:00 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 01:03 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.
