Hurricane Ginger was the second longest-lasting Atlantic hurricane on record. The eighth tropical cyclone and fifth hurricane of the 1971 Atlantic hurricane season, Ginger spent 27.25 days as a tropical cyclone, lasting from September 6 to October 3. Twenty of those days (September 11 – September 30), Ginger was classified as a hurricane. The storm formed northeast of the Bahamas, and for the first nine days of its duration tracked generally eastward or northeastward while gradually strengthening to peak winds of 110 mph (175 km/h). On September 14, Ginger slowed and turned to a general westward track, passing near Bermuda on September 23. There, the hurricane produced gusty winds and high waves, but no damage.
While over the western Atlantic Ocean, Ginger became the last target of Project Stormfury, which sought to weaken hurricanes by depositing silver iodide into tropical cyclone rainbands. Ginger ultimately struck North Carolina on September 30 as a minimal hurricane, lashing the coastline with gusty winds that caused power outages across the region. Heavy rainfall flooded towns and left severe crop damage, with 3 million bushels of corn and 1 million bushels of soybean lost. Damage in the state was estimated at $10 million (1971 US dollars$, USD). Further north, moderate precipitation and winds spread through the Mid-Atlantic states, although no significant damage was reported outside North Carolina.
Ginger has the highest accumulated cyclone energy for a hurricane below major hurricane strength in the Atlantic basin, at 44.2.
Meteorological history
Hurricane Ginger originated in a cold-core upper-level low that persisted for several days in early September in the Western Atlantic Ocean. By September 5, the low had descended to the surface as its thermal structure warmed, and the next day it developed into a tropical depression about 235 mi (375 km) northeast of the Bahamas.
After forming, the depression moved slowly southeastward for about 24 hours before turning to the northeast, slowly organizing in the process. On September 10, the depression turned eastward, and later that day intensified into Tropical Storm Ginger, the seventh named storm of the year in the Atlantic, about 325 mi (525 km) south of Bermuda. The storm quickly intensified, and within 24 hours reached winds of 75 mph (120 km/h), making it a hurricane. It turned to the northeast, passing well to the east of Bermuda. Late on September 13, Ginger attained its minimum barometric pressure of 959 mbar (28.32 inHg), and early the next day reached peak maximum sustained winds of 110 mph (175 km/h). After reaching a position about halfway between Bermuda and the Azores, the hurricane's eastward movement halted due to a building ridge to its north and east. It turned sharply southward before turning and beginning a westerly drift, during which Ginger weakened to minimal hurricane status. On September 18, Ginger turned to the south and slowly executed a tight counterclockwise loop within three days. By September 21, the hurricane was tracking south of due west, and the next day suddenly intensified to winds of 90 mph (150 km/h). Its westward track briefly posed a threat to Bermuda, although Ginger passed 115 mi (185 km) south of the island on September 23 while slowly weakening. On September 24, Ginger decelerated before beginning a turn to the southwest. By September 26, Ginger briefly weakened to minimal hurricane strength, although re-intensification resumed as the track turned to the west and northwest.

For three days, beginning on September 26, the National Oceanic and Atmospheric Administration deployed planes into the hurricane as part of Project Stormfury, the fourth hurricane to be a part of the weather control experiment. By September 28, Ginger was moving northwestward toward North Carolina and was steadily intensifying. At around 06:00 UTC the next day, the hurricane reached a secondary peak intensity of 105 mph (165 km/h), which it maintained for about 18 hours. Afterward, Ginger slowly weakened, and late on September 30 it made landfall near Morehead City, North Carolina, with winds of 75 mph (120 km/h). It quickly deteriorated over land, weakening first to a tropical storm and then to a tropical depression by late on October 1. Ginger turned to the north, entered southern Virginia, and later turned to the east. On October 3, it transitioned into an extratropical cyclone while crossing Hampton Roads into the Atlantic Ocean. The remnants of Ginger continued east-southeastward until being absorbed by a cold front on October 5. The United States military also evacuated some planes and secured the units that remained. Officials closed all of the island's schools during Ginger's passage.
Before Ginger struck North Carolina, the American Red Cross set up 28 emergency shelters in six counties, where about 5,500 people stayed during the storm. The National Hurricane Center issued a hurricane watch from Wilmington, North Carolina, to Virginia Beach, Virginia, with gale warnings extending northward to Rehoboth Beach, Delaware. United States military officials evacuated planes and ships from the Norfolk, Virginia, region, in addition to flying planes down the coast to warn boaters of the approaching storm. Ferry services around the Outer Banks were canceled during the storm's passage, while the Coast Guard ordered the evacuation of workers in three lighthouses.
Impact

As the hurricane passed south of Bermuda on September 23, it produced heavy waves, as well as gale force winds for 17 hours. Naval Air Station Bermuda reported peak gusts of 75 mph (120 km/h).
While Ginger was still in the vicinity of Bermuda, it produced high swells and riptides along the East Coast of the United States, prompting the issuing of small craft warnings from Florida to North Carolina. Wave heights reached in Sebastian, Florida, and one person was killed in St. Augustine from drowning. There were also initial reports of two missing people in Neptune Beach, Florida, but they were not listed as casualties in the year-end hurricane summary. Several oil tanks along the rivers broke open, creating dangerous boating conditions. Up to of water from the Pungo River flooded most of the city of Belhaven, and similar flooding occurred in Washington, entering dozens of buildings and houses. Across the region, the combination of high winds, tides, and flooding closed several bridges and roads, including a portion of U.S. Highway 70. The winds also destroyed several mobile homes,
Further inland, the combination of strong winds and rains left heavy crop damage, destroying 3 million bushels of corn and another million bushels of soybeans; losses to the corn crop were mitigated due to about half of the crop having been harvested before the storm's arrival. Heavy damage was also reported to the peanut crop as well as to various fruits and vegetables. In some locations, up to 15% of the cotton crop was lost, particularly in the northeastern portion of the state. In 45 counties in the eastern portion of the state, farmers affected by the hurricane were eligible for loans from the Farmers Home Administration, following federal approval from United States President Richard Nixon. Governor Robert W. Scott requested federal disaster aid for 24 counties, which was denied. Damage in North Carolina was estimated at $10 million (1971 USD$, USD), Further north, Ginger produced above-normal tides, light winds, and scattered rainfall along the Delmarva Peninsula and northward through New York.
