EF0 tornado, Aaron to Blitch, Georgia, March 26, 2011

From Aaron to Blitch, this EF0 tornado ran 0.6 miles across Bulloch County on March 26, 2011, touching down at 7:40 PM EDT and reaching 100 yards wide. It killed nobody, and did $40,000 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 mphthis tornado

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

  2. EF186 to 110 mph

    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.

What the Weather Service recorded

A stationary frontal boundary in combination with modest instability, resulted in the development of scattered strong to severe thunderstorms across southeast Georgia.

A National Weather Service storm survey confirmed an EF0 Tornado with a path length of 0.6 miles and a maximum path width of 100 yards. Two mobile homes had siding and under-siding damaged along with some minor shingle damage. The tornado also snapped and uprooted dozens of trees.

A National Weather Service storm survey confirmed and EF1 tornado with a path length of 3.1 miles and a maximum path width of 0.25 miles. One mobile home was completely destroyed and thrown 30 yards from its foundation by the tornado. Several outbuildings, sheds, and carports were damaged or destroyed and hundreds of trees were snapped or uprooted.

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

The warnings

15 minutes of warning. NWS CHS issued a tornado warning for this county at 23:25 UTC, 15 minutes before the tornado touched down, in force until 00:15 UTC.

The county was under a tornado watch, issued at 23:40 UTC and running to 03:29 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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 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.
