EF1 tornado, Wilshire to Parkersburg, Georgia, September 2, 2016

From Wilshire to Parkersburg, this EF1 tornado ran 1.4 miles across Chatham County on September 2, 2016, touching down at 5:12 AM EDT and reaching 350 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

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

  • North extent of main damage
  • Looking south, lots of large pine and some hardwoods broken/snapped and uprooted.
  • More than 1/2 roof removed. No clips seen. Many large pines snapped. Center passes just west of house. No other homes right next to this one had any structural damage.
  • Many trees snapped, mostly soft wood, just west of house that lost roof.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

Hermine developed as a Tropical Depression near the north coast of Cuba on August 28th. The depression then tracked westward into the central Gulf of Mexico and strengthened into a Tropical Storm. Hermine then tracked generally northeastward and strengthened into a Hurricane. According to the National Hurricane Center, Hermine made landfall as a Category 1 Hurricane at 1:30 am EDT on September 2nd along the Florida Big Bend coast just east of St. Marks, Florida, near the Wakulla-Jefferson County line. Hermine continued on a northeastward track across the Florida panhandle and into southeast Georgia and southeast South Carolina, gradually weakening back to a Tropical Storm. Across southeast Georgia and southeast South Carolina, the main impacts from Hermine included heavy rain and wind damage in the form of scattered to numerous trees being blown down. Storm total rainfall amounts generally ranged from 2 to 8 inches across the region, including a daily record rainfall of 2.32 inches at the Charleston International Airport. The wind damage produced numerous power outages and even some damage to homes and other structures throughout the area. Hermine spawned 2 tornadoes, and produced a 1.5 to 2.5 foot storm surge along the coast, though no flooding was reported.

A National Weather Service survey team confirmed a tornado near Skidaway Island. The tornado touched down in Romerly Marsh of Skidaway Island and was associated with the rainbands from Tropical Storm Hermine. The tornado moved northward into the residential area known as The Landings. More than 20 homes sustained roof damage from large trees falling on them after either being snapped or uprooted. One home in The Landings lost about one half of it's roof from wind pushing up on a large gable structure. Several other homes sustained minor to moderate roof damage. Hundreds of large pine and oak trees were either snapped or uprooted from the winds. The storm moved north at approximately 30 to 35 miles per hour and dissipated over the northern portion of The Landings, near the intersection of N Landings Way and McWhorter Drive.

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

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 02:47 UTC and running to 11:51 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 05:18 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.
