EF2 tornado, Knightdale Wndll Arp to Mt Pleasant, North Carolina, May 13, 2019

From Knightdale Wndll Arp to Mt Pleasant, this EF2 tornado ran 17.2 miles across Wake and Nash counties on May 13, 2019, touching down at 10:13 AM EDT and reaching 385 yards wide. It killed nobody, and did $1.3 million 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 mph

    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 mphthis tornado

    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 southward moving cold front interacted with a rather unstable air mass for mid to late morning into the early afternoon across the area and allowed for the development of an isolated cluster of thunderstorms across the central Piedmont and central Coastal Plain of central North Carolina. The cluster of thunderstorms become severe and produced wind damage, very large hail and a EF-2 tornado as shortwave disturbance moved across the area allowing the convection to quickly intensify.

The tornado initially touched down just west of Rolesville Road |near Tink's Place in eastern Wake County. The tornado initially |produced widespread EF-1 damage with sporadic EF-2 damage noted on |Weathers Road. Along the path to Weathers Road, numerous trees |were either uprooted or snapped and mangled together, consistent |with EF-1 damage. | |At Weathers Road, structural damage was noted as a single family |home had its exterior walls collapsed. Several metal farm |buildings were also completely destroyed and strewn about a field. |Sheet metal was wrapped around a nearby tree. An RV was flipped |over numerous times landing crushed in an open field. In |addition, another home had the windows blown out with roof damage. |It was in this area that EF-2 damage was determined. | |The tornado continued tracking east and crossed Edgemont Road just |north of HWY 264/64, then crossing HWY 264/64 where numerous trees |were downed and snapped. Generally EF-1 damage was noted here. | |The tornado then moved east into Zebulon along and near Highway |97 (West Gannon Avenue) where numerous trees snapped and uprooted. |It continued east of Zebulon, crossing HWY 264/64 again, and going |just north of the Five County Stadium. Generally EF-0 and EF-1 |damage was noted here.

The Tink's Place tornado continued into western Nash County and then crossed into Nash County, where damage was observed on Brantley Road. Most of the damage consisted of trees being snapped and uprooted, with structural damage to an open-air |farm outhouse. Just east on Massey Road, one newly constructed home suffered roof damage, with roof trusses severely damaged. Shingles had not been completed on the home yet, therefore this damage was considered EF-1 level. Also on Massey Road, a modular home suffered roof and wall damage, while two farm outhouses were severely damaged. The tornado then tracked east along Nade Road causing more uprooted and snapped trees. A home along Nade Road also lost its chimney with a cinderblock outhouse suffering complete roof failure. | |Finally, the tornado began to weaken as it crossed the woods east of Hoyt Road, and it eventually lifted just east of Winters Road.

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 14:47 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.
