EF1 tornado, Cosgrove to Eminence, Arkansas, May 20, 2025

From Cosgrove to Eminence, this EF1 tornado ran 11.6 miles across Chicot County on May 20, 2025, touching down at 5:04 PM CDT and reaching 700 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.

The damage survey

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

  • At least 10 wooden poles snapped

What the Weather Service recorded

Severe storms produced damaging winds, hail, and a tornado in southeast Arkansas.

An EF-1 tornado tracked along Arkansas Highway 160, beginning near the County Road 252 intersection, and it continued through Chicot Junction and lifted east of US Highway 65. Along the path, several utility poles were snapped along Arkansas 160, and several trees were snapped or uprooted. Two metal farm buildings along the Boeuf River were damaged, with one having concrete anchors pulled from the ground aided by the open air layout of the building. The tornado lifted within a fielded area east of Bayou Macon. The maximum estimated wind speeds were 110 mph.

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

The warnings

1 minute of warning. NWS JAN issued a tornado warning for this county at 22:03 UTC, 1 minute before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 18:10 UTC and running to 00:00 UTC.

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 19:52 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.
