EF0 tornado, Agua Fria, New Mexico, May 9, 2017

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 mphthis tornado

    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 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 potent upper level low pressure system moving slowly east across the desert southwest for several days combined with abundant moisture and instability on the 9th to generate a widespread, significant severe weather outbreak over central and eastern New Mexico. Isolated thunderstorms developed shortly after midnight in the area from Santa Fe to Farmington and produced quarter size hail with heavy rain and and strong winds. A large area of showers and thunderstorms developed shortly after sunrise over central New Mexico and moved north across the Albuquerque and Santa Fe metro areas through the early afternoon. Several funnel clouds and large hail were reported around the Estancia Valley. A brief tornado develop near the Santa Fe airport shortly after noon with minor damage reported. A major hailstorm struck the Interstate 25 corridor near Kewa Pueblo, resulting in damage to homes and vehicles. The next wave of storms that developed over central New Mexico produced tornadoes near Carrizozo, Clines Corners, and Wagon Mound. Large hail up to the size of golf balls was also reported with these storms. More storms firing up around the Albuquerque metro area produced nickel to quarter size hail from Rio Rancho north into the Jemez Mountains. Severe thunderstorms continued to pound eastern New Mexico well into the evening hours with golf ball to hen egg size hail producing damage in areas around Roswell and Tucumcari.

A severe thunderstorm crossed Interstate 25 east of the Santa Fe airport then moved north along NM-599. This storm produced a brief EF-0 tornado 2.8 miles northeast of the Santa Fe airport, near NM-599 and Agua Fria, then tracked toward the north for approximately 0.3 miles. Mainly localized and minor damage was observed with this tornado event. The Santa Fe Airport tower personnel also spotted a funnel cloud north of the airport.

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 16:26 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.
