EF1 tornado, Retreat to Riceboro, Georgia, September 2, 2016

From Retreat to Riceboro, this EF1 tornado ran 4.8 miles across Liberty County on September 2, 2016, touching down at 3:50 AM EDT and reaching 650 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

3 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 98 mph.

  • Tent/ outbuilding destroyed. Large Plastic Water tank (1/2 filled) was tipped over.
  • Part of metal roof peeled off of wooden building.

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 Riceboro. The tornado touched down just north of Blackbeard Creek, about one half of a mile east of Interstate 95. The tornado moved north at 30 to 35 miles per hour toward the remote and heavily wooded area of South Hampton Island, and then continued north across North Hampton Island. Overall, it was estimated that a few thousand trees were snapped or uprooted across the region. The worst damage occurred across portions of North Hampton Island where many large oak and pine trees were snapped or had large limbs removed. Additionally, minor damage occurred to a few structures throughout the property due to trees falling on them. The tornado dissipated just north of Ferry Road on North Hampton Island.

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

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.

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.
