F0 tornado, Copeland to Millry, Alabama, March 18, 1996

From Copeland to Millry, this F0 tornado ran 4.0 miles across Washington County on March 18, 1996, touching down at 4:30 PM CST and reaching 300 yards wide. It killed nobody, and did $10,000 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 mphthis tornado

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

  2. F173 to 112 mph

    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

THE SAME STORM SYSTEM THAT DROPPED A TORNADO IN MISSISSIPPI MOVED INTO SOUTHWEST ALABAMA. ANOTHER TORNADO TOUCHED DOWN ABOUT TWO MILES NORTHWEST OF COPELAND. THE TORNADO SKIPPED ALONG THE GROUND FOR ABOUT FOUR MILES BEFORE LIFTING BACK INTO THE CLOUD ABOUT TWO MILES NORTHEAST OF COPELAND. DAMAGE WAS CONFINED TO DOWNED TREES AND POWER LINES.

THE SAME STORM SYSTEM KEPT MOVING EAST NORTHEAST AND DROPPED ANOTHER TORNADO TWO MILES SOUTHEAST OF MILLRY. THE TORNADO SKIPPED ALONG THE GROUND AND CROSSED COUNTY ROAD 34 ABOUT THREE MILES EAST OF MILLRY. THE TORNADO STAYED ON THE GROUND FOR ABOUT FIVE MILES AND LIFTED BACK INTO THE CLOUD SIX MILES NORTHEAST OF MILLRY. DAMAGE WAS AGAIN CONFINED TO TREES AND POWER LINES.

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

The warnings

13 minutes of warning. NWS MOB issued a tornado warning for this county at 22:17 UTC, 13 minutes before the tornado touched down, in force until 23:15 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 High Risk. The outlook in force was issued at 06:00 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.
