Hurricane Florence was a long-lived Cape Verde hurricane and the wettest tropical cyclone on record in the Carolinas. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. Florence became a tropical depression near Cape Verde on August 31 and progressed west-northwest, becoming a Tropical Storm on September 1. Florence strengthened rapidly on September 4���5, becoming a Category 4 storm on the Saffir-Simpson wind scale with maximum sustained winds of 130 mph. Florence weakened to a tropical storm by September 7, but the system regained hurricane strength on September 9 and major hurricane status with winds of 140 mph on September 10. However, increasing wind shear caused the storm's winds to gradually weaken over the next few days. However, the storm's wind field continued to grow. By the evening of September 13, Florence had been downgraded to a Category 1 hurricane. Hurricane Florence made landfall near Wrightsville Beach early on Saturday September 15, and weakened further as it slowly moved inland.||Florence produced extensive wind damage along the North Carolina coast from Cape Lookout, across Carteret, Onslow, Pender and New Hanover counties. Thousands of downed trees caused widespread power outages to nearly all of eastern North Carolina. The historic legacy of Hurricane Florence will be record breaking storm surge of 9 to 13 feet and widespread devastating rainfall of 20 to 30 inches, locally up to 36 inches, which produced catastrophic and life-threatening flooding. The hardest hit areas included New Bern, Newport, Belhaven, Oriental, North Topsail Beach and Jacksonville, along with Downeast Carteret County, or basically south of a line from Kinston to Cedar Island. A storm total rainfall of 34.00 inches was reported in Swansboro, while the NWS office in Newport recorded 25.20 inches. Wind gusts of 106 mph were reported at Cape Lookout with 105 mph at Fort Macon.

NWS storm survey team confirmed the tornado occurred near Swan Quarter. The damage path started near Farrow Rd, and consisted of a large softwood that was snapped. More softwoods were snapped along with some hardwoods being uprooted along Oyster Creek St. A large waterspout was reported off the ferry terminal at Swan Quarter by the ferrymaster. The end of the pathw was an end over the western part of the Pamlico Sound based on the eyewitness account. Due to less than 10 trees being snapped and only a few hardwoods uprooted, maximum estimated winds were at the lower end of the scale or around 90 mph. The time was based on radar 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 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 12:50 UTC.

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.
