The Sunset Beach tornado was an unusually rare but deadly tornado that struck on February 15, 2021, causing significant damage to the area. Rated EF3 on the Enhanced Fujita Scale, this tornado had maximum wind speeds of 160, near EF4 threshold. This tornado would cause considerable damage, with 37,000 people reported power loss. While being part of a larger outbreak, this was the strongest tornado, and the deadliest as well. The tornado would stay largely in rural areas, though it would start and impact Sunset Beach. After causing fatalities in the town, this tornado then tracked through marsh areas and then dissipate.

After the National Weather Service had completed their survey, the tornado was rated EF3.


Metrological Setup

[edit]
The outlook when the tornado had formed.

On February 13, a frontal storm formed off the coast of the Pacific Northwest and made landfall in California and Washington, before moving southeastward, with the storm becoming disorganized in the process.[3] A low level trough formed from February 12-13, fueling the storm. The trough became fully mature by February 15, channeling significant amounts of moisture into the winter storm and also contributing to a historic cold wave that affected most of the Central and Eastern United States.[4]

Meanwhile, the NWS had issued a marginal risk for northern Florida at 09:29 UTC (4:29 a.m., EST[note 1]) (with no risk for tornadoes.[5] At 12:00 UTC ( 7:00 AM EST), the risk was upgraded to a marginal risk, with a 2% risk over eastern North Carolina. At this time, a strong shortwave trough had moved from the southern Plains that morning across the lower Mississippi Valley that afternoon. With a strengthening upper jet spreading northeastward across the Appalachians, this allowed for storms to develop. At the surface, a low pressure over the Gulf of Mexico had moved inland across the Florida Panhandle during the early afternoon as a warm front brought 60 °F (16 °C) dewpoints ashore and into southern GA.[5] As the day wore on, The SPC outlined an Enhanced risk tornadoes, and a 5% risk was present over these areas.[6] At 11:00 p.m. EST on February 15, data from the Storm Prediction Center indicated atmospheric instability exceeding 1,000 J/kg and an effective bulk shear of approximately 45 knots. These parameters supported an area of strong thunderstorms moving northeastward across South Carolina. As the system interacted with a warm front, rotation increased, leading to the formation of a tornado in Brunswick County.[7]

Tornado Narrative

[edit]
Thousands of trees that were destroyed.

As the sun set, the front had neared Carolina Shores, the cold front spawned a QLCS tornado at 11:34 PM EST in Calabash.[8] It left Calabash and rapidly inflicting weak EF0 damage to the Sea Trail Golf Resort, knocking over several trees. After leaving the resort, it hit Sandpiper Bay Resort as well. Quickly strengthening, it reached F2 intensity and destroyed many mobile homes. Then it weekend to EF1 and knocked over some trees.[9] Shortly after this, the tornado strengthened, causing low end EF3 tornado damage to houses in the Sunset Beach neighborhood.[10] As the tornado continued, it briefly strengthened to high end EF3, destroying several buildings outside of Sunset beach.[11] Here, it would also reach it's max width of 275 yards. It flattened at least 3 homes as it hit Windsor Circle. After this, the tornado then crossed over Ocean Highway, quickly weakening into a EF2 with 115 mph wind speeds. While crossing the highway, it destroyed many power utilities, causing severe power outages.[12] It impacted more homes after this, including a home on Old Shallotte Road where a tree impaled a house at EF2 intensity.[13][14] The tornado would cause EF1 damage as it reached the end of it's path, and would weaken again while traveling through marshlands. When the tornado reached N.C. 904, it destroyed a large metal building and overturned a number of RVs. The National Weather Service estimates that wind speeds were estimated to have reached low end EF2.[15]

It would down over a thousand trees in a path, before lifting at 12:02, shortly after midnight.[16][9] The supercell did not produce anymore tornadoes after that, and soon was consumed by the front.[note 2]

Aftermath

[edit]

Preparations

[edit]

The SPC had outlined a 5% risk for tornadoes, but more concerned had been focused in Northern Florida-Southern Alabama area, where a 10% for tornadoes was in place. At 11:33 pm, the NWS had issued a Severe Weather Warning, but few people received this warning.[17] The tornado itself would strike near midnight, and there was no warning for the tornado before, or after it touched down. A tornado warning was issued however, after the tornado had begun damage, leaving residents with little time to prepare.[18]

Damage

[edit]

At least 50 homes were damaged in Sunset Beach.[19] The golf course nearby also sustained significant damage. Around 37,000 customers lost power during the height of the storms.[20] Two large warehouses also collapsed during the tornado.[21] This tornado became the deadliest single tornado in Southeastern North Carolina since an F3 touched down on November 16, 2006,[22] and the first deadly tornado on record in Brunswick County.[23] There were also ten injuries.[24]

Response

[edit]

Governor Roy Cooper signed a state of emergency for Sunset Beach on February 25.[25] Cooper also designated the week of March 7-13 as “Severe Weather Awareness Week”, and ordered tornado drills at school on March 10.[26]
