EF0 tornado, Mt Gould to Meege Xrds, North Carolina, May 5, 2017

From Mt Gould to Meege Xrds, this EF0 tornado ran 11.7 miles across Chowan and Bertie counties on May 5, 2017, touching down at 7:27 AM EDT and reaching 100 yards wide. It killed nobody, and did $205,000 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.

The damage survey

21 damage points were recorded along this path by NWS AKQ, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

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

Scattered severe thunderstorms in advance of low pressure and its associated cold front produced damaging winds and two tornadoes across portions of northeast North Carolina.

The initial tornado touchdown occurred in eastern Bertie county along Blackrock Road, snapping the tops out of trees and uprooting a few other trees as it moved northeast towards the Chowan River. Wind speeds in Bertie county were estimated around 60 to 70 mph. The tornado then tracked northeast across the Chowan River and entering Chowan county along Tynch Town Road.

The tornado tracked from Bertie county into Chowan county. In Chowan county, the tornado uprooted trees and caused minor damage to homes from Tynch Town Road and Whites Landing Road northeast to Evans Bass Road and Rocky Hock Landing Road. A barn was severely damaged on Evans Bass Road. The tornado then crossed Rocky Hock Road destroying a barn along with several outbuildings. Another barn was severely damaged and windows were blown in on a nearby house. Numerous large pines were snapped and winds were estimated at 80 mph along Rocky Hock Road.||The tornado continued moving northeast knocking a single wide mobile home off its foundation near Parish Road. More outbuildings were destroyed and a house sustained minor damage with shingle and siding loss near the intersection of Nixon Road and Parish Road. The tornado weakened as it crossed Rocky Hock Road a second time just west of Highway 32 where several trees were snapped. The end of the tornado was observed along Highway 32 just north of Center Hill Road where a few trees were uprooted.

The forecast that day

The Storm Prediction Center had this point in a Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 05:30 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.
