List of off-season Atlantic hurricanes

The list of off-season Atlantic hurricanes includes 36 tropical or subtropical cyclones that formed outside of the official Atlantic basin season, which is currently defined from June 1 to November 30. [Chris Landsea.

January

*January 18, 1978 - A westerly trough caused the development of a surface low pressure, which developed into Subtropical Storm One. It strengthened to gale force winds due to a pressure gradient, and initially tracked west-northwest and then southwest. It soon weakened, dissipated, and opened into a trough.cite web|format=PDF|author=Miles B.

February

*February 2, 1952 - A tropical storm formed in the northwest Caribbean Sea, after shortly being a tropical depression, and quickly moved northeastward. It passed over the Florida Keys and then made landfall at the southern end of Florida's peninsula, dropped 2–4 inches (51 to 102 mm) of rain, and caused damage to crops in southern Miami-Dade County. The storm then moved parallel to the Eastern Seaboard before skirting Cape Cod, Massachusetts and the east coast of Maine.

March

*March 6, 1908 - First being observed well to the northeast of the Lesser Antilles, a tropical cyclone strengthened to hurricane status while moving southwestward. It entered the Caribbean Sea between Saint Kitts and Nevis as a Category 2 hurricane on the Saffir-Simpson scale,cite web|author=Hurricane Research Division|year=2008|title=Atlantic Hurricane Best Track (1851-2007)|publisher=NOAA|accessdate=2008-08-06|url=http://www.aoml.noaa.gov/hrd/hurdat/easyhurdat_5107.html] producing a pressure of 991 mbar (29.27 inHg) and 8 in (203 mm) of rainfall.

April

*April 20, 2003 - An area of low pressure formed by the interaction of an upper-level trough and a surface frontal trough, which brought moisture from the Caribbean into the system and caused rain in Puerto Rico, while 240 miles (390 km) south-southwest of Bermuda.cite web|author=Jack Beven|year=2003|title=Tropical Storm Ana Tropical Cyclone Report|publisher=National Hurricane Center|accessdate=2007-12-14|url=http://www.nhc.noaa.gov/2003ana.shtml?] [cite web|author=Mike Tichacek|year=2003|title=April 18 Tropical Weather Discussion|publisher=National Hurricane Center|accessdate=2007-12-14|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/Atl-Dis/2003/Apr/2003041804.AXNT20] The non-tropical low moved northward and it began producing sporadic convection, and it then turned to the northwest, but then looped southeast and separated from the surface trough. It developed into a subtropical storm while 250 mi (400 km) west of Bermuda. After a upper-level warm core formed over the system it became Tropical Storm Ana, and Ana later reached peak strength of 60 miles per hour (95 km/h). Upper-level wind shear removed much of its convection, the upper-level system then separated and the storm reorganized with a eye-like feature. However, it once again weakened due to wind shear, became extratropical, and lost its identity near the Azores.cite web|author=Richard Pasch|year=2003|title=Subtropical Storm Ana Discussion Two|publisher=National Hurricane Center|accessdate=2007-12-15|url=http://www.nhc.noaa.gov/archive/2003/dis/al012003.discus.002.shtml?] cite web|author=Jack Beven|year=2003|title=Subtropical Storm Ana Discussion Five|publisher=National Hurricane Center|accessdate=2007-12-15|url=http://www.nhc.noaa.gov/archive/2003/dis/al012003.discus.005.shtml?] Ana dropped 2.63 in (67 mm) of rain at Bermuda International Airport over a six-day period, and two died as a result of their boat capsizing at Jupiter Inlet, Florida.

*April 21, 1992 - A low- to mid-level low pressure area separated from the prevailing westerlies about 600 mi (1100 km) southeast of Bermuda; after organizing and a low-level circulation forming it developed into a subtropical depression and later into Subtropical Storm One.cite web|author=National Hurricane Center|accessdate=2007-08-21|year=1992|title=Subtropical Storm One Preliminary Report|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1992/st1/prenhc/prelim01.gif] With a large area of convection in its eastern sector, the cyclone attained peak winds of 50 mph (85 km/h).Cite web|author=Lawrence|year=1992|title=Subtropical Storm One Discussion One|publisher=National Hurricane Center|accessdate=2007-08-21|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1992/st1/tropdisc/nal0192.001] As a trough approached it, it decelerated as its convection diminished, soon became stationary, and weakened into a depression as strong upper-level wind shear affected it.Cite web|author=Jarrell|year=1992|title=Subtropical Storm One Discussion Three|publisher=National Hurricane Center|accessdate=2007-08-21|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1992/st1/tropdisc/nal0192.003] It moved east-northeastward, still maintaining a small amount of deep convection, but it soon dissipated, maintaining an eastward course.cite web|author=Rappaport|year=1992|title=Subtropical Depression One Discussion Seven|publisher=National Hurricane Center|accessdate=2007-08-21|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1992/st1/tropdisc/nal0192.007]

May

*May 5, 1932 - Developing in the western Caribbean Sea, a tropical storm crossed the Dominican Republic before turning northward and later to the northwest. It dissipated over the open western Atlantic.
*May 6, 1981 - A system moved across from the Pacific, across Central America, into the Atlantic, and soon developed into a tropical depression with a low-level circulation. It then strengthened into Tropical Storm Arlene, with deep convection near the center, crossed eastern Cuba, and weakened into a depression. Arlene dissipated east of the Bahamas and merged with a cloud mass.cite web|format=PDF|author=Miles B. Lawrence; Joseph M.

*May 13, 1916 - A tropical depression forms near Cuba, and moving northward it crosses much of Florida before accelerating northeastward. It becomes extratropical over the Carolinas, and eventually dissipates in New England.
*May 14, 1933 - The first storm in the 1933 season – the second-most active Atlantic season on record – developed in the western Caribbean Sea. It tracked northwestward and curved around the Yucatán Peninsula before making landfall in the Mexican state of Tabasco.
*May 15, 1887 - A tropical storm formed southeast of Bermuda. Moving northwestward toward the island, it strengthened to near hurricane-force before weakening and turning to the northeast. After transitioning into an extratropical cyclone, it moved over the Canadian Maritimes.
*May 15, 1951 - A subtropical depression formed 300 mi (480 km) south of Bermuda, and quickly moved northwest, then turned west-southwestward. It strengthened into a tropical storm, 125 mi (200 km) east of Daytona Beach, Florida, and further into a hurricane later that day.cite web|author=Paul Moore and Walter Davis|year=1951|title=A Preseason Hurricane of Subtropical Origin|publisher=Weather Bureau Office|accessdate=2007-02-14|url=http://www.aoml.noaa.gov/hrd/hurdat/mwr_pdf/1951.pdf] cite web|author=Grady Norton|year=1952|title=Hurricanes of 1951|publisher=Weather Bureau Office|accessdate=2007-02-14|url=http://www.aoml.noaa.gov/hrd/hurdat/mwr_pdf/1951.pdf] Hurricane Able moved northeast and then northward and its eye increased in diameter to 20 mi (32 km), as its sustained wind speed peaked at 115 mph (185 km/h). It passed about 70 mi (110 km) east of Cape Hatteras, North Carolina, and then turned east and deteriorated over cooler waters.
*May 16, 1889 - Forming north of Puerto Rico, a tropical storm tracked northwestward, becoming a hurricane before turning northeast and dissipating away from land.
*May 17, 1887 - A tropical storm formed in the western Caribbean Sea while another cyclone was located in the western Atlantic Ocean; this marked one of only three occasions where two tropical cyclones co-existed during the off-season. The storm moved near or across Jamaica, Cuba, and the Bahamas before dissipating southwest of Bermuda.
*May 17, 1970 - A weak tropical depression formed in the southwest Caribbean and slowly organized as it moved northward. It rapidly deepened, soon became Hurricane Alma, and reached its peak intensity of convert|80|mi/h|km/h|abbr=on. Westerly shear soon weakened the system, it quickly became a depression, and later dissipated. Seven deaths resulted in central and eastern Cuba, as a result of heavy rain which caused flash flooding.cite web|format=PDF|author=R. H. Simpson; Joseph M.

*May 19, 1940 - A tropical storm moves generally northward then northeastward in the western Atlantic for several days, remaining away from land before dissipating.
*May 21, 1976 - An interaction between a trough and a stationary front caused the development of scattered cloudiness and showers over the Gulf of Mexico and the northwest Caribbean. An area of low pressure developed, became stationary, and soon strengthened into Subtropical Storm One. The storm then accelerated east-northeast, quickly crossed north Florida and southwest Georgia, and merged into a frontal system after crossing into the Atlantic.cite web|format=PDF|author=Miles B.

*May 23, 1972 - A broad area of low pressure moved northeastward from the east coast of Florida towards Cape Hatteras, North Carolina, where its forward motion was blocked a high pressure ridge. It was pushed southward and a small well-defined area of low pressure quickly developed into Subtropical Storm Alfa, as it reached gale force winds. It soon made landfall south of Brunswick, Georgia, with a small region of subtropical storm force winds.cite web|format=PDF|author=R. H. Simpson; Paul J.

*May 24, 1908 - Forming north of Hispaniola, a tropical cyclones moves northwestward until turning to the northeast near Florida. It attains hurricane status – the second hurricane of the season and only season on record with two hurricanes before June 1 – and passes just east of North Carolina, producing tropical storm force winds on land.cite web|author=Hurricane Research Division|year=2008|title=Chronological List of All Hurricanes which Affected the Continental United States: 1851-2007|publisher=NOAA|accessdate=2008-08-06|url=http://www.aoml.noaa.gov/hrd/hurdat/ushurrlist18512007.txt] Continuing northeastward, it strikes New England and dissipates over Maine as an extratropical cyclone.
*May 25, 1953 - Tropical Storm Alice forms in the western Caribbean, and executes a large cyclonic loop that brings it over Central America before a continued northward track. The storm hits western Cuba, and after looping again Alice moves across the Gulf of Mexico. It strikes the Florida Panhandle in early June, quickly dissipating.
*May 27, 1890 - A tropical depression moves across western Cuba, intensifies into a tropical storm in the Gulf of Mexico, and subsequently dissipates.
*May 27, 1934 - After moving across southern Florida, a tropical storm hits South Carolina and executes a small loop before dissipating.
*May 28, 1959 - An easterly wave centered over the Dominican Republic moved into the northwest Caribbean with a weak circulation. A pressure gradient built up extensively in and near the Florida Straits, impacting the area with wind. The center of the storm moved into the southeast Gulf of Mexico, developed a low level circulation, and it became Tropical Storm Arlene. The storm then moved westward, soon stationary, and then made landfall in southern Louisiana. It weakened significantly afterward, and the center moved northeast across northern Alabama and Georgia. Arlene caused rainfall from southeast Louisiana to northern Georgia, which caused severe flooding and crop damage.cite web|format=PDF|author=Gordon E.

*May 31, 2008 - The interaction between a tropical wave and the remnants of Tropical Storm Alma from the Pacific Ocean develop into Tropical Storm Arthur just off the coast of Belize. It quickly moves ashore, producing severe flooding and heavy damage totaling $78 million (2008 USD). The storm, which later dissipates over the Yucatán Peninsula, caused five deaths in Belize.cite web|author=Blake|title=Tropical Storm Arthur: Tropical Cyclone Report|year=2008|publisher=National Hurricane Center|accessdate=2008-07-29|url=http://www.nhc.noaa.gov/pdf/TCR-AL012008_Arthur.pdf]

December

*December 4, 1887 - A tropical storm formed and became a hurricane over the central Atlantic. It tracked toward the Azores, but became extratropical and turned to the north. Early in its duration, it co-existed with a tropical cyclone that formed in November, one of three times when two storms co-existed in the off-season.
*December 4, 2003 - A low pressure area developed just to the north of Panama within the area of a stationary front, and an anticyclone above provided good inflow.cite web|author=James Franklin|year=2003|title=Tropical Storm Odette Tropical Cyclone Report|publisher=National Hurricane Center|accessdate=2007-12-22|url=http://www.nhc.noaa.gov/2003odette.shtml] [cite web|author=Mike Wallace|year=2003|title=December 1 Tropical Weather Discussion|publisher=National Hurricane Center|accessdate=2007-12-22|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/Atl-Dis/2003/Dec/2003120105.AXNT20] The low remained stationary for days, slowly separated from the front, and convection began to increase due to moisture from the eastern Pacific Ocean and some divergence.

It developed into a tropical depression while 345 mi (560 km) south of Kingston, Jamaica, and the convection soon organized into a central dense overcast. The depression soon became Tropical Storm Odette, and it strengthened even with moderate southwesterly wind shear, and an eye feature soon formed.cite web|author=Lixion Avila|year=2003|title=Tropical Storm Odette Discussion Two|publisher=National Hurricane Center|accessdate=2007-12-22|url=http://www.nhc.noaa.gov/archive/2003/dis/al202003.discus.002.shtml?] Odette later reached peak winds of 65 mph (100 km/h) while located about 245 mi (395 km/h) southwest of Santo Domingo, Dominican Republic. The storm disorganized somewhat and made landfall on Jaragua National Park, in the Pedernales Province of the Dominican Republic with winds of 60 mph (95 km/h). It emerged into the Atlantic weakened and soon became extratropical.
*December 7, 1887 - A tropical storm forms near the Lesser Antilles, and moves across the Caribbean Sea. Its path is generally west-southward, and it ultimately dissipates after making landfall on Costa Rica. For two days this storm was active with the previous cyclone, making it one of three times when two cyclones were simultaneously active in the off-season.
*December 7, 1953 - A tropical depression quickly developed into Tropical Storm Fourteen northeast of the Lesser Antilles. It moved westward, weakened to a tropical depression once more, and then dissipated.cite web|title=1953 Atlantic hurricane season track map|accessdate=2008-05-01|publisher=United States Department of Commerce Weather Bureau|url=http://www.nhc.noaa.gov/tracks/1953atl.gif] cite web|title=Tropical Storm 14 Track Data|accessdate=2008-05-01|publisher=Unisys|url=http://weather.unisys.com/hurricane/atlantic/1953/14/track.dat]
*December 7, 2003 - An extratropical cyclone developed 1430 mi (2300 km) southwest of the Azores islands, and later as a gale developed convection near the center, the cyclone developed into a subtropical storm. As convection and rainbands continued to develop near the center of the storm, it became Tropical Storm Peter while 980 mi (1580 km) northwest of Praia in the Cape Verde islands.cite web|author=David Roth|year=2003|title=Tropical Storm Peter track prior to cyclogenesis|accessdate=2006-10-12|url=http://www.australiasevereweather.com/cyclones/2004/trak0312.htm] cite web|author=Avila|year=2003|title=Tropical Storm Peter Tropical Cyclone Report|publisher=NHC|accessdate=2006-10-12|url=http://www.nhc.noaa.gov/2003peter.shtml] Peter soon developed an eye feature and strengthened to peak winds of 70 mph (110 km/h). The storm moved northward towards the same frontal system that absorbed Odette, and soon strong upper-level winds and cooler water temperatures weakened Peter. It quickly became a tropical depression, dissipated, and was absorbed by an approaching cold front.cite web|author=Avila|year=2003|title=Tropical Storm Peter Tropical Cyclone Report|publisher=NHC|accessdate=2006-10-12|url=http://www.nhc.noaa.gov/2003peter.shtml]

*December 11, 2007 - A upper-level low moving westward led to the development of a surface trough east of the northern end of the Lesser Antilles. It slowly moved westward, produced some convection, began to organize, and then continued westward through an area of fairly warm sea surface temperatures.cite web|author=David Roth|year=2007|title=Rainfall Summary for Tropical Storm Olga|publisher=Hydrometeorological Prediction Center|accessdate=2007-12-20|url=http://www.hpc.ncep.noaa.gov/tropical/rain/olga2007.html] cite web|author=Gladys Rubio|year=2007|title=December 7 Tropical Weather Discussion|publisher=National Hurricane Center|accessdate=2007-12-11|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/Atl-Dis/2007120717.AXNT20] [cite web|author=James Franklin|year=2007|title=December 9 Special Tropical Disturbance Statement|publisher=National Hurricane Center|accessdate=2007-12-11|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/Disturbance/2007120921.WONT41] With an upper-level low just to the south of the center of the system, it became Subtropical Storm Olga while 55 mi (85 km) east of San Juan, Puerto Rico.cite web|author=Beven|year=2007|title=Subtropical Storm Olga Discussion One|publisher=National Hurricane Center|accessdate=2007-12-12|url=http://www.nhc.noaa.gov/archive/2007/al17/al172007.discus.001.shtml?] Afterwards, it maintained a well-defined outflow, moved west-southwestward, strengthened as it paralleled the northern coast of Puerto Rico, and made landfall near Punta Cana, Dominican Republic.cite web|author=Knabb & Mainelli|year=2007|title=Subtropical Storm Olga Discussion Two|publisher=National Hurricane Center|accessdate=2007-12-12|url=http://www.nhc.noaa.gov/archive/2007/al17/al172007.discus.002.shtml?] It became Tropical Storm Olga overland after a Hurricane Hunters flight discovered the storm's peak winds of 60 mph (95 km/h) and a tighter wind gradient.cite web|author=Avila|year=2007|title=Tropical Storm Olga Public Advisory Four-A|publisher=National Hurricane Center|accessdate=2007-12-12|url=http://www.nhc.noaa.gov/archive/2007/al17/al172007.public_a.004.shtml?] As it moved across central Hispaniola, the cyclone's convection weakened rapidly, and when it moved into the Caribbean Sea, it soon dissipated into a remnant system.cite web|author=Franklin & Mainelli|year=2007|title=Tropical Storm Olga Discussion Seven|publisher=National Hurricane Center|accessdate=2007-12-12|url=http://www.nhc.noaa.gov/archive/2007/al17/al172007.discus.007.shtml?] Olga later moved into the Gulf of Mexico, redeveloped some convection, but soon impacted Florida with tropical storm force winds, before merging with a cold front.

*December 12, 1984 - A frontal trough stalled south of Bermuda, and a upper-level disturbance soon moved over it and produced widespread convection over the system. As it developed circulation within its convection, it moved to the northeast, and soon became a subtropical storm while 275 mi (440 km) northeast of Bermuda.cite web|author=National Hurricane Center|year=1984|title=Hurricane Lili Preliminary Report Page 1|accessdate=2007-03-31|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1984-prelim/lili/prelim01.gif] The subtropical storm had winds of 60 mph (95 km/h), was strengthening, and drifted eastward, but was soon forced southeast by a ridge. It was forced southward as a upper-level low formed over the system, soon turned northeast as the ridge weakened, and the storm accelerated to a speed of 40 mph (65 km/h).cite web|author=National Hurricane Center|year=1984|title=Hurricane Lili Preliminary Report Page 2|accessdate=2007-03-31|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1984-prelim/lili/prelim02.gif] After moving erratically, it was soon became Hurricane Lili, while 730 mi (1180 km) east of Bermuda, and reached peak strength of 80 mph (130 km/h). Lili was soon forced southwest, finished its large cyclonic loop after a week, and vertical wind shear and its high forward speed caused it to weaken. It weakened to a tropical storm while 430 mi (690 km) northeast of Antigua and dissipated just north of the Dominican Republic.cite web|author=National Hurricane Center|year=1984|title=Hurricane Lili Preliminary Report Page 2|accessdate=2007-03-31|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1984-prelim/lili/prelim02.gif]
*December 29, 2005 - A tropical depression developed from a frontal trough, and into Tropical Storm Zeta as convective banding developed near the center of the storm.cite web|author=National Hurricane Center|title=Tropical Cyclone Report: Tropical Storm Zeta|publisher=NOAA|accessdate=May 1|accessyear=2006|format=PDF|url=http://www.nhc.noaa.gov/pdf/TCR-AL312005_Zeta.pdf] It weakened slightly, but soon restrengthened to 65 mph (100 km/h) winds, and defied meteorologists by not weakening quickly.cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 4 a.m. EST, January 3 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.016.shtml] cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 10 a.m. EST, January 4 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.021.shtml] It slowly weakened into a remnant low, and dissipated 660 mi (1060 km) southeast of Bermuda. Zeta affected crews participating in the 2005 Atlantic Rowing Race, but never affected land.cite web|author=Woodvale Events Ltd|title=Atlantic Rowing Race 2005 Press Release: Tropical Storm Zeta|accessdate=May 1|accessyear=2006|url=http://www.atlanticrowingrace.co.uk/news_releases/newsdetail.php?id=32]
*December 30, 1954 - A trough extending from a front, had increased convection as it moved over 1º C (34º Fahrenheit) above-average temperature waters, and then underwent tropical cyclogenesis. It developed into a tropical depression 770 mi (1245 km) east-northeast of Barbuda in the Lesser Antilles and an area of high pressure both sent it west-southwestward and prevented cold air from reaching it from the central Atlantic Ocean. The system strengthened into a tropical storm and into Hurricane Alice the next day 475 mi (770 km) east-northeast of Barbuda. Alice continued southwest, entered the Caribbean Sea, and its eyewall moved over Saint Martin and Saba. Alice soon weakened and began to turn extratropical, and later dissipated while 100 mi (160 km) west-northwest of Grenada. Only a few islands in the Lesser Antilles received damage, due to the small size of Alice, those being Saint-Barthélemy, Saba, Anguilla, Sint Eustatius, and Saint Kitts.cite web|author=José A.
