F1 tornado, Richton to Avera, Mississippi, February 19, 1996

From Richton to Avera, this F1 tornado ran 21.0 miles across Perry and Greene counties on February 19, 1996, touching down at 2:35 PM CST and reaching 400 yards wide. It killed nobody, and did $90,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 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. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 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

NUMEROUS TREES WERE TOPPLED AND SEVERAL MOBILE HOMES WERE DAMAGED BY A TORNADO THAT FIRST TOUCHED DOWN IN THE NORTHWEST PART OF GREENE COUNTY. THE TORNADO FIRST TOUCHED DOWN ABOUT SIX MILES EAST OF RICHTON ON MS HWY 42 AT ABOUT 220 PM CDT. THE TORNADO THEN SKIPPED ALONG THE GROUND TO THE NORTHEAST AND MOVED INTO WAYNE COUNTY ALONG MS HWY 63. NUMEROUS TREES WERE BLOWN DOWN ALONG THE PATH OF THE TORNADO AND SEVERAL MOBILE HOMES WERE DAMAGED. FOUR PEOPLE IN ONE OF THE MOBILE HOMES WERE INJURED. THE TORNADO WAS ON THE GROUND FOR ABOUT 5 MILES IN GREENE COUNTY.

A TORNADO FIRST TOUCHED DOWN IN PERRY COUNTY NEAR REDHILL WHICH IS ABOUT 6 MILES SOUTH OF NEW AUGUSTA AT ABOUT 235 PM CDT. THE TORNADO THEN MOVED NORTHEAST ACROSS MS HWY 29 KNOCKING DOWN SEVERAL TREES IN ITS PATH. THE TORNADO CONTINUED SKIPPING ALONG THE GROUND CROSSING US HWY 98 JUST WEST OF BEAUMONT. THE TORNADO DAMAGED ROOFS ON THREE HOMES JUST SOUTH OF KITTRELL AND WEST OF MS HWY 15. THE TORNADO CROSSED MS HWY 15 NEAR KITTRELL AND DAMAGED SIDING AND SHINGLES FROM SEVERAL HOMES HERE. THE TORNADO THEN CONTINUED NORTHEAST ACROSS OPEN PASTURE KNOCKING DOWN TREES. THE TORNADO SKIPPED ALONG THE GROUND FOR ABOUT 13 MILES IN PERRY COUNTY BEFORE MOVING INTO GREENE COUNTY, 3 MILES WEST OF PLEASANT HILL. NO INJURIES WERE REPORTED.

A TORNADO THAT BEGAN IN PERRY COUNTY MOVED INTO GREENE COUNTY THREE MILES WEST OF PLEASANT HILL. THE TORNADO SKIPPED ALONG THE GROUND ACROSS MOSTLY OPEN PASTURE FOR ABOUT NINE MILES BEFORE LIFTING BACK INTO THE CLOUD JUST EAST OF STATE HIGHWAY 63, 3 MILES SOUTHEAST OF AVERA. THE TORNADO BLEW DOWN SEVERAL TREES ALONG ITS PATH AND ALSO DAMAGED THE ROOFS OF A COUPLE OF HOMES. NO INJURIES WERE REPORTED.

The warnings

9 minutes of warning. NWS MOB issued a tornado warning for this county at 20:26 UTC, 9 minutes before the tornado touched down, in force until 21:15 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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. The outlook in force was issued at 05:32 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.
