EF1 tornado, Vanoss, Oklahoma, May 24, 2025

This EF1 tornado ran 2.6 miles across Pontotoc County on May 24, 2025, touching down at 4:10 AM CDT and reaching 50 yards wide. It killed nobody, and did $75,000 of property damage.

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.

The damage survey

1 damage points were recorded along this path by NWS OUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 110 mph.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

The approximately 36-hour period, beginning during the initial hours of the 24th, featured three unique severe convective episodes across the WFO Norman Forecast Area. The initial round, triggered by moist isentropic ascent, featured scattered organized thunderstorms, including a few supercell thunderstorms. This activity produced primarily reports of large hail. However, localized storm-scale interactions across Cleveland, Pottawatomie, and Pontotoc Counties resulted in concentrated corridor of thunderstorm wind damage, as well as a tornado near Vanoss, OK, in Pontotoc County. During the same general time frame, a separate organized line of thunderstorms moved from far southern Kansas into north-central Oklahoma producing a few observed severe-caliber wind gusts. ||Following the morning activity, dry and pleasant conditions occurred for much of the day on the 24th. However, by near-sunset, a destabilizing boundary layer near and south of a warm front across western and southern Oklahoma fostered the development of a few briefly intense thunderstorms. Finally, a progressive and high-intensity wake low and heat burst event evolved from portions of western-north Texas into central Oklahoma during the late evening of the 24th into the 25th. This event, tied to decaying severe convection from across central Texas, featured strong and occasionally damaging wind gusts.

This tornado developed near the community of Vanoss and moved southeast. A home suffered significant roof damage along County Road 3450. Scattered damage was observed by emergency management personnel southeast to near the intersection of County Roads 3470 and 1570.

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 05:35 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.
