EF1 tornado, Folsom, Alabama, January 3, 2023

This EF1 tornado ran 0.1 miles across Perry County on January 3, 2023, touching down at 12:10 PM CST and reaching 100 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

5 damage points were recorded along this path by NWS BMX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 95 mph.

What the Weather Service recorded

A long-duration severe weather event occurred from the late morning hours of Tuesday, January 3rd to the early morning hours of Wednesday, January 4th. Several rounds of rain and thunderstorms impacted Central Alabama, producing tornadoes, damaging straight-line winds, quarter size hail, and flooding.

National Weather Service meteorologists surveyed damage in northern Perry County and determined that it was consistent with an EF1 tornado, with maximum winds near 95 mph. This short-lived tornado developed and dissipated quickly near Coretta Scott King Highway. A manufactured home was shifted off its block foundation with a large section of roofing material removed from the back side of the home. Two homeowners were present during the time of impact and were tossed onto the floor. Thankfully, there were no injuries. Metal panels were lofted into trees on either side of the highway and a few trees were uprooted and snapped.

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

The warnings

7 minutes of warning. NWS BMX issued a tornado warning for this county at 18:03 UTC, 7 minutes before the tornado touched down, in force until 18:45 UTC.

The county was under a tornado watch, issued at 15:17 UTC and running to 21:37 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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:20 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.
