Activity was steady through most of the season. Hurricane Edith was its strongest system, becoming a strong Category 4 on the Saffir–Simpson scale. It struck Nicaragua at peak intensity, killing dozens, and later hit southern Louisiana. Hurricane Ginger, the second of the season's two major hurricanes, was its longest-lived system, lasting 27 days from early September to early October, setting a record for the longest known duration of a North Atlantic tropical cyclone (not surpassed until 2003). Ginger moved ashore in North Carolina, producing heavy rains and damaging winds. An unnamed storm in August attained hurricane status further north than any other Atlantic hurricane on record. On September 11–13, there were five active Atlantic tropical cyclones at one time.Six Tropical Cyclones At Once in the Pacific Ocean: How Rare Is That? https://weather.com/storms/typhoon/news/five-tropical-cyclones-pacific-july2015 Erdman John August 27, 2015 September 17, 2017 weather.com Despite the activity, damage in the United States totaled about $235 million (1971 USD, US 235000000 1971  USD), which National Hurricane Center forecaster Paul Hebert noted was "pretty small considering we had five storms in a row strike the U.S." Most of the damage came from Tropical Storm Doria, which affected much of the East Coast of the United States. Hurricane Fern struck Texas after executing an unusual track, dropping heavy rainfall and producing flooding. __TOC__ Systems Tropical Storm Arlene Atl ArleneJuly51971.png Arlene 1971 path.png July 4 July 7 50 1000 The origins of Arlene were from a cold front that exited the East Coast of the United States on July 2 and stalled offshore. A frontal wave developed the next day, steadily developing due to thermal instability. On July 4, the system organized into Tropical Storm Arlene about 125 mi km on southeast of Cape Fear, North Carolina. While in its formative stages, it dropped rainfall along the coast of the Carolinas, peaking at 4.11 in mm on in Pinopolis, South Carolina.David M. Roth November 3, 2008 Tropical Storm Arlene – July 3–5, 1971 March 4, 2011 Hydrometeorological Prediction Center http://www.wpc.ncep.noaa.gov/tropical/rain/arlene1971.html Arlene tracked northeastward due to a ridge over New England, and the cyclone passed just southeast of the Outer Banks. In the post-season summary, meteorologist Neil Frank noted, "the surprising element in the development of Arlene was the rapidity of the transformation process." Arlene continued northeastward, possessing a circular mass of convection with spiral rainbands. Late on July 6, the storm attained peak winds of 60 mph (95 km/h), based on a ship report. It weakened thereafter, and Arlene transitioned into an extratropical cyclone early on July 7 just south of Sable Island. The storm capsized a boat in the Grand Banks of Newfoundland, and the crew of 12 was rescued.Canadian Hurricane Centre November 3, 2010 1971-Arlene September 28, 2021 http://www.ec.gc.ca/Hurricane/default.asp?lang=En&n=31E122D8-1 https://web.archive.org/web/20130313111709/http://www.ec.gc.ca/Hurricane/default.asp?lang=En&n=31E122D8-1 March 13, 2013 Unnamed hurricane Atl August51971IntenseST.gif 04L 1971 path.png August 3 August 6 70 ≤974 A hybrid-type depression formed east of Bermuda on July 29. It moved rapidly southwestward before turning to a northwest drift. On August 3, it was classified as a tropical depression, and the next day the system passed near Bermuda. The depression accelerated to the northeast, strengthening into a tropical storm on August 5. It intensified further due to baroclinity, or enhanced instability through different levels of the atmosphere caused by temperature and moisture gradients.Atmospheric Science: An Introductory Survey John M. Wallace Peter V. Hobbs 386–390 Academic Press, Inc. 1977 978-0-12-732950-5 On August 6, a drilling rig about 230 mi km on southeast of Newfoundland recorded sustained winds of 90 mph km/h on with gusts to 126 mph (204 km/h) at an altitude of 325 ft m on; this suggested the storm attained hurricane status at 44°North, which is the northernmost location for a tropical storm to intensify into a hurricane.https://www.theweathernetwork.com/en/news/weather/forecasts/hurricane-pablo-becomes-historic-storm-after-briefly-strengthening-in-the-atlantic-ocean The Weather Network Pablo: Small, but historic hurricane based on its weird spot in the Atlantic October 28, 2019 September 22, 2026 Despite the intensity, the cyclone was not purely tropical; although the radius of maximum winds was only 35 mi km on, the thermal structure did not resemble a tropical cyclone, and there was no precipitation or convection near the center. It continued northeastward as a strong extratropical cyclone and meandered across the far northern Atlantic. It was not named operationally, but it was later added to the Atlantic hurricane database. Hurricane Beth Hurricane Beth Atl BethAug1519711727UTCESSA9.gif Beth 1971 path.png August 10 August 17 75 977 On August 9, an upper-level low developed off the coast of Florida, and the next day spawned a tropical depression near Grand Bahama. After briefly moving southeastward across the island, the newly developed cyclone tracked slowly northeastward, eventually encountering conditions favorable for development. Late on August 13, the depression intensified into Tropical Storm Beth off the coast of North Carolina, and it quickly strengthened into a hurricane by August 15. After reaching peak winds of 85 mph km/h on off the coast of Cape Cod, Beth slightly weakened and later moved ashore near Copper Lake, Nova Scotia as a strong tropical storm. Shortly thereafter, Beth was swept up by a nearby cold front and transitioned into an extratropical cyclone. The hurricane left extensive damage in its wake, especially to crops and infrastructure.Natural Resources Canada Major Hurricanes The Atlas of Canada November 1, 2010 http://atlas.nrcan.gc.ca/site/english/maps/environment/naturalhazards/naturalhazards1999/majorhurricanes/hurricanes_stats_new.html dead https://web.archive.org/web/20110602021559/http://atlas.nrcan.gc.ca/site/english/maps/environment/naturalhazards/naturalhazards1999/majorhurricanes/hurricanes_stats_new.html June 2, 2011 Halifax International Airport reported 10.49 in (266 mm) of rainfall in a 30‑hour span, which caused widespread flooding.The Associated Press Hurricane Beth Pours Rain on Nova Scotia; One Killed August 17, 1971 The Spokesman-Review November 1, 2010 https://news.google.com/newspapers?id=K-0vAAAAIBAJ&sjid=Y-0DAAAAIBAJ&pg=7288,239060&dq=hurricane-beth+canada&hl=en Several bridges in the region were washed out, while railways were covered by water, forcing trains to suspend their operation.The Canadian Press Nova Scotia awash as rain, storms hit August 16, 1971 The Windsor Star November 1, 2010 https://news.google.com/newspapers?id=O0M_AAAAIBAJ&sjid=rlAMAAAAIBAJ&pg=2155,379553&dq=hurricane-beth+canada+warnings&hl=en Overall monetary damage from Beth is estimated up to $5.1 million (1971 USD, US 5100000 1971  USD).

It quickly moved through the Lesser Antilles, where it produced wind gusts up to 58 mph km/h on. The cyclone also dropped heavy rainfall up to 6 in mm on on Barbados and Martinique. After entering the eastern Caribbean Sea, the depression intensified into Tropical Storm Chloe on August 20. About 18 hours after attaining tropical storm status, Chloe quickly strengthened to peak winds of 60 mph km/h on about 215 mi (345 km) south of the Mona Passage, as reported by reconnaissance aircraft. After reaching peak intensity, Chloe began weakening as it turned to the west-southwest, and late on August 22, it was downgraded to a tropical depression as a weakening ridge to its north cut off the low-level inflow. For several days it continued generally westward, gradually losing organization.

Doria turned to the north, and reached peak winds of 70 mph (110 km/h) as it was making landfall near Morehead City, North Carolina. It turned to the northeast hugging the coast and holding its intensity as it passed the North Carolina and Virginia coasts (although it may have briefly become a hurricane - the data was inconclusive), and moved through the Mid-Atlantic and New England as a tropical storm before becoming an extratropical storm over Maine on August 28.Delgado Sandy Cobb Hugh Landsea Christopher W.

Hurricane Fern Atl Fern09-1971.JPG Fern 1971 path.png September 3 September 13 75 978 Hurricane Fern Hurricane Fern was the first of four tropical systems to develop in association with an extended surface trough across the Gulf of Mexico into the open Atlantic, along with Ginger, Heidi, and a strong tropical depression. Fern developed on September 3 in the central Gulf of Mexico. It moved very close to southern Louisiana the next day, but due to increased ridging to the north the depression moved southwestward and remained over water. On September 7, the depression intensified into Tropical Storm Fern. Fern later turned to the northwest, intensifying into a hurricane on September 10. It quickly reached peak winds of 85 mph km/h on, moving ashore early on September 11 between Freeport and Matagorda, Texas as a tropical storm. Fern dissipated on September 13 over northeastern Mexico. The precursor of Fern dropped rainfall up to 5 in mm on of rainfall across South Florida, while totals of up to 10 in mm on were reported in southeastern Louisiana where it made its first landfall. As it struck Texas, Fern produced strong winds up to 86 mph km/h on, along with 5 to 6 ft m on storm tides and heavy rainfall; the highest precipitation total was 26.0 in mm on in Beeville. The heavy rainfall caused severe flash flooding that isolated numerous small towns in the southeastern portion of the state, damaging 7,500 buildings. In all, Fern left two indirect deaths and moderate damage totaling $30.2 million (1971 USD, US 30200000 1972  USD).David M.

It moved quickly across the southern Caribbean Sea, intensifying into a hurricane just off the north coast of South America. Edith rapidly intensified on September 9 and made landfall on Cape Gracias a Dios as a strong Category 4 hurricane on the Saffir-Simpson Hurricane Scale. It quickly lost intensity over Central America and after briefly entering the Gulf of Honduras it crossed the Yucatán Peninsula in Mexico. After moving across the Gulf of Mexico, a trough turned the storm to the northeast and Edith, after having restrengthened while accelerating towards the coast, made landfall on Louisiana with winds of 90 mph (150 km/h) on September 16.

It developed into a tropical depression on September 21 about 1050 mi (1700 km) west-southwest of Cape Verde, which was the easternmost formation of the named storms this season. The next day, the depression intensified into Tropical Storm Janice, and quickly reached peak winds of 50 mph km/h on. The storm never became well-organized, with its peak winds located east of the broad center. Despite being in a climatologically favored region for further development, Janice weakened due to increased wind shear from Hurricane Ginger. The circulation became elongated and separated from the convection, and on September 24 the storm weakened to a tropical depression. Later that day Janice dissipated just northeast of the Lesser Antilles as it was absorbed by Ginger. Around that time, it produced rainfall in the northeastern Caribbean, reaching 4 in mm on on Saint Kitts; no damage or fatalities were reported. Subtropical Storm Kristy Atl subtropical Kristy 71.JPG Kristy 1971 path.png October 18 October 21 60 992 The interaction between a tropical wave and an upper-level trough led to the development of a subtropical depression on October 18, about 685 mi (1100 km) northeast of Puerto Rico. It moved quickly north-northeastward, followed by a curve to the northeast. On October 20, a ship reported winds of 45 mph km/h on, indicating the depression intensified into Subtropical Storm Kristy.Subtropical storms were not named prior to 2002; Kristy was operationally considered tropical but reanalyzed in 2026. nb As it reached this strength, an approaching cold front produced cooler, drier air over the storm. Kristy intensified slightly further to peak winds of 70 mph (110 km/h) before becoming indistinguishable from the cold front. By October 21 it transitioned into an extratropical cyclone before dissipating near the Azores. Tropical Storm Laura Atl Tropical Storm Laura 1971.jpg Laura 1971 path.png November 12 November 22 60 994 A large area of convection persisted across the southwest Caribbean Sea in mid-November. On November 12, a tropical depression formed about 175 mi km north of Panama. It moved northwestward, slowly organizing and becoming Tropical Storm Laura on November 14. The storm continued to intensify as it turned northward toward western Cuba. Late on November 15, Laura attained peak winds of 70 mph km/h on. A ridge over the southeastern United States caused Laura to drift and execute a clockwise loop off the west coast of Cuba. By early on November 18, the storm was weakening and moving southwestward away from Cuba. The track shifted but continued generally to the southwest, as the intensity fluctuated from 50–70 mph (80–110 km/h), and due to the hints of an eye at times on radar, may have reached hurricane status during this period. On November 21, Laura made landfall at peak intensity near Punta Gorda, Belize. It dissipated the next day over Guatemala. When Tropical Storm Laura first passed the Cayman Islands, it produced 3 in mm of rainfall on Grand Cayman.Associated Press 1971-11-13 Tropical Storm Laura Could Become Hurricane 2010-02-26 https://news.google.com/newspapers?id=N4UsAAAAIBAJ&sjid=88wEAAAAIBAJ&pg=5566,3013517&dq=tropical+laura&hl=en As it was slowly moving off of the coast of Cuba, Laura dropped heavy rainfall, including nearly 20 in mm across most of the Isle of Youth.

On the mainland, the storm destroyed 20 homes and several tobacco sheds, with damage also reported to the coffee, sugar, fruit, and vegetable crops. Due to the flooding, officials forced 26,000 people from their homes in Pinar del Río, and one person in that province drowned while crossing a river.Associated Press The Evening Independent November 19, 1971 Laura Weakens off Yucatan Coast February 27, 2010 https://news.google.com/newspapers?id=3eALAAAAIBAJ&sjid=iFcDAAAAIBAJ&pg=5553,5186296&dq=tropical+laura&hl=en The storm's passage was believed to have diverted a flock of great black-backed gulls toward Central America and north-coastal South America; the species is usually found in the Mid-Atlantic states, and were migrating to the Gulf Coast or Cuba when they were affected by the storm.V.H.

Note: a reanalysis project revised or removed some of these systems from HURDAT in 2026 In addition to the named storms and otherwise notable cyclones, there were several weak depressions during the season. After a June devoid of activity, three tropical depressions developed within the first ten days of July. The first became Tropical Storm Arlene on July 4. Another tropical depression formed in the northwestern Gulf of Mexico from a surface low-pressure area on July 9, quickly moving ashore in southern Texas before dissipating on July 11; it dropped light rainfall along its path.David M.

It moved west-northwestwar before dissipating on September 7, although it may have briefly reached tropical storm intensity. The final non-developing tropical depression of the season formed on October 6 in the western Caribbean Sea. It crossed the Yucatán Peninsula the next day, dropping heavy rainfall up to 9.09 in mm on. The depression turned to the northeast due to an approaching upper-level trough, and it transitioned into a frontal wave on October 10. As the trough advanced ahead of the storm, a ridge built across the southeast United States, causing the cyclone to turn northward and parallel the west coast of Florida. It regained tropical characteristics before moving ashore near Apalachicola and dissipating on October 14.David M.
