- 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 1to November 30. [Chris Landsea. [http://www.aoml.noaa.gov/hrd/tcfaq/E16.html Subject: E16) When did the earliest and latest hurricanes occur?] Retrieved on 2008-06-10.] The list excludes tropical depressions, as well as other cyclones not in the Atlantic hurricane database (HURDAT).
*January 18, 1978 - A westerly trough caused the development of a surface
low pressure, which developed into Subtropical Storm One. It strengthened to galeforce 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 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 Keysand 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 cropsin southern Miami-Dade County. The storm then moved parallel to the Eastern Seaboard before skirting Cape Cod, Massachusettsand the east coast of Maine.

*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 Seabetween Saint Kittsand Nevisas 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 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 shearremoved 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 Airportover a six-day period, and two died as a result of their boat capsizing at Jupiter Inlet, Florida.

*May 5, 1932 - Developing in the western Caribbean Sea, a tropical storm crossed the
Dominican Republicbefore 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 Bahamasand 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 Floridabefore 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 Peninsulabefore 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 Bahamasbefore 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

*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 Mexicoand the northwest Caribbean. An area of low pressure developed, became stationary, and soon strengthened into Subtropical Storm One.

*May 25, 1953 - Tropical Storm Alice forms in the western Caribbean, and executes a large cyclonic loop that brings it over
Central Americabefore a continued northward track. The storm hits western Cuba, and after looping again Alice moves across the Gulf of Mexico. It strikes the Florida Panhandlein 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.

Florida, a tropical storm hits South Carolinaand executes a small loop before dissipating.
*May 28, 1959 - An easterly wave centered over the
Dominican Republicmoved 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 Alabamaand Georgia. Arlene caused rainfall from southeast Louisiana to northern Georgia, which caused severe flooding and crop damage.cite web|format=PDF|author=Gordon E.

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 Provinceof 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 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 shearand its high forward speed caused it to weaken. It weakened to a tropical storm while 430 mi (690 km) northeast of Antiguaand 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 30, 1954 - A trough extending from a front, had increased
convectionas 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 Barbudain the Lesser Antillesand an area of high pressureboth 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 eyewallmoved over Saint Martinand 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 Antillesreceived damage, due to the small size of Alice, those being Saint-Barthélemy, Saba, Anguilla, Sint Eustatius, and Saint Kitts.cite web|author=José A.
