EF0 tornado, Flying H Ranch, New Mexico, September 15, 2016

This EF0 tornado ran 4.7 miles across Chaves County on September 15, 2016, touching down at 2:10 PM MDT and reaching 50 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 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

The upper level trough responsible for severe weather across the area on the 14th continued to impact New Mexico through the 15th. Abundant moisture and instability associated with southeasterly upslope flow and strong upper level dynamics generated an extended period of severe weather across the eastern plains. Severe thunderstorms from late on the 14th persisted past midnight before diminishing before sunrise. A powerful storm that moved south of Melrose just after midnight produced one of the best radar signatures of a tornado forecasters have ever observed in eastern New Mexico. A nearby resident reported a loud roaring sound in the distance. A persistent storm with torrential rainfall amounts over four inches in eastern San Miguel County produced flash flooding along Atarque Creek through sunrise. Storms fired up quickly again by late morning and moved east across the plains. A funnel cloud was observed just after the noon hour near Vaughn. Another storm that moved east across Lincoln County dumped nickel to quarter size hail in the area around Tinnie, Picacho, and Dunken. A tornado and golf ball size hail was then spotted from this storm over rural ranch lands to the northeast of Dunken. Many other storms that impacted eastern New Mexico generated hail, torrential rainfall, and gusty winds throughout the afternoon.

Public reported a tornado on the ground just north of U.S. Highway 82 near Picacho Road. No damage observed.

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

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 19:49 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.
