The 1959 Atlantic hurricane season featured near normal tropical cyclone activity overall. The season officially began on June 15, 1959 and lasted until November 15, 1959. These dates historically described the period in each year when most tropical cyclogenesis occurs in the Atlantic basin. However, the formation of a tropical cyclone is possible at any time of the year, as shown in 1959, by the formation of Tropical Storm Arlene on May 28. Arlene struck Louisiana and brought minor flooding to the Gulf Coast of the United States. The next tropical storm, Beulah, formed in the western Gulf of Mexico and brought negligible impact to Mexico and Texas. Later in June, an unnamed hurricane, caused minor damage in Florida, and then devastated parts of Maritime Canada, resulting in what became known as the Escuminac disaster. Hurricane Cindy brought minor impact to The Carolinas. In late July, Hurricane Debra produced flooding in the state of Texas. Tropical Storm Edith in August and Hurricane Flora in September caused negligible impact on land.
The 1970 Atlantic hurricane season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season was fairly average, with 14 named storms forming, of which seven were hurricanes. Two of those seven became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. Also, this was the first season in which reconnaissance aircraft flew into all four quadrants of a tropical cyclone.
The 1976 Atlantic hurricane season was an fairly average Atlantic hurricane season in which 21 tropical or subtropical cyclones formed. 10 of them became nameable storms. Six of those reached hurricane strength, with two of the six became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first system, a subtropical storm, developed in the Gulf of Mexico on May 21, several days before the official start of the season. The system spawned nine tornadoes in Florida, resulting in about $628,000 (1976 USD) in damage, though impact was minor otherwise.
The 1947 Atlantic hurricane season was the first Atlantic hurricane season to have tropical storms labeled by the United States Air Force. The season officially began on June 16, 1947, and ended on November 1, 1947. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first tropical cyclone developed on June 13, while the final system was absorbed by a cold front on December 1. There were 10 tropical storms; 5 of them attained hurricane status, while two became major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson scale. Operationally, the third tropical storm was considered two separate tropical cyclones, resulting in the storm receiving two names. The eighth tropical storm went undetected and was not listed in HURDAT until 2014.
The 1944 Atlantic hurricane season featured the first instance of upper-tropospheric observations from radiosonde – a telemetry device used to record weather data in the atmosphere – being incorporated into tropical cyclone track forecasting for a fully developed hurricane. The season officially began on June 15, 1944, and ended on November 15, 1944. These dates describe the period of each year when most tropical cyclones form in the Atlantic basin. The season's first cyclone developed on July 13, while the final system became an extratropical cyclone by November 13. The season was fairly active season, with 14 tropical storms, 8 hurricanes, and 3 major hurricanes. In real-time, forecasters at the Weather Bureau tracked eleven tropical storms, but later analysis uncovered evidence of three previously unclassified tropical storms.
The 1942 Atlantic hurricane season was one of seven seasons to feature multiple hurricane landfalls in Texas. The season officially lasted from June 16, 1942, to October 31, 1942. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. A total of 11 tropical storms from 1943 are listed in the Atlantic hurricane database, with two additional tropical depressions. The first system of the year, a tropical depression, developed over the central Gulf of Mexico on June 3, while the last system, the Belize hurricane, dissipated over the Yucatán Peninsula on November 11. After the depression dissipated on June 3, the season remained dormant until the next system developed two months later. In mid-August, a hurricane struck Texas, causing about $790,000 (1942 USD) in damage.
The 1935 Atlantic hurricane season was a near-normal hurricane season. Altogether, ten tropical cyclones developed, eight of which intensified into tropical storms. Five of those tropical storms strengthened into hurricanes, while three of those reached major hurricane intensity. The season ran from June 1 through November 15, 1935.
The 1932 Atlantic hurricane season featured several powerful storms, including the Cuba hurricane, which remains the deadliest tropical cyclone in the history of Cuba and among the most intense to strike the island nation. It was a relatively active season, with fifteen known storms, six hurricanes, and four major hurricanes. However, tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. The Atlantic hurricane reanalysis project discovered four new tropical cyclones, all of which were tropical storms, that occurred during the year. Two storms attained Category 5 intensity, the first known occurrence in which multiple Category 5 hurricanes formed in the same year. The season's first cyclone developed on May 5, while the last remaining system transitioned into an extratropical cyclone by November 13.
The 1926 Atlantic hurricane season featured the highest number of major hurricanes at the time. At least eleven tropical cyclones developed during the season, all of which intensified into a tropical storm and eight further strengthened into hurricanes. Six hurricanes deepened into a major hurricane, which is Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. It was a fairly active and deadly season. The first system, the Nassau hurricane, developed near the Lesser Antilles on July 22. Moving west-northwest for much of its duration, the storm struck or brush several islands of the Lesser and Greater Antilles. However, the Bahamas later received greater impact. At least 287 deaths and $7.85 million (1926 USD) in damage was attributed to this hurricane. The next cyclone primarily affected mariners in and around the Maritimes of Canada, with boating accidents and drownings resulting in between 55 and 58 fatalities. In late August, the third hurricane brought widespread impact to the Gulf Coast of the United States, especially Louisiana. Crops and buildings suffered $6 million in damage and there were 25 people killed.
The 1921 Atlantic hurricane season was an active hurricane season, with 12 tropical cyclones forming. Among them, seven became tropical storms, of which five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane, Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale, the most since the 1917 season. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three tropical cyclones co-existed with another during the season.
The 1916 Atlantic hurricane season featured eighteen tropical cyclones, of which nine made landfall in the United States, the most in one season until 2020, when eleven struck. The first storm appeared on May 13 south of Cuba, while the final tropical storm became an extratropical cyclone over the southeastern Gulf of Mexico on November 15. Of the 18 tropical cyclones forming that season, 15 intensified into a tropical storm, the second-most at the time, behind only 1887. Ten of the tropical storms intensified into a hurricane, while five of those became a major hurricane. The early 20th century lacked modern forecasting tools such as satellite imagery and documentation, and thus, the hurricane database from these years may be incomplete.
The 1915 Atlantic hurricane season was an active Atlantic hurricane season in which six tropical storms developed. The first storm, which remained a tropical depression, appeared on April 29 near the Bahamas, while the final system, also a tropical depression, was absorbed by an extratropical cyclone well south of Newfoundland on October 22. Of the six tropical storms, five intensified into a hurricane, of which three further strengthened into a major hurricane. Four of the hurricanes made landfall in the United States. The early 20th century lacked modern forecasting and documentation, and thus, the hurricane database from these years may be incomplete.
The 1912 Atlantic hurricane season was an average hurricane season that featured the first recorded November major hurricane. There were eleven tropical cyclones, seven of which became tropical storms; four of those strengthened into hurricanes, and one reached major hurricane intensity. The season's first cyclone developed on April 4, while the final dissipated on November 21. The season's most intense and most devastating tropical cyclone was the final storm, known as the Jamaica hurricane. It produced heavy rainfall on Jamaica, leading to at least 100 fatalities and about $1.5 million (1912 USD) in damage. The storm was also blamed for five deaths in Cuba.
The 1911 Atlantic hurricane season was a relatively inactive hurricane season, with only six known tropical cyclones forming in the Atlantic during the summer and fall. There were three suspected tropical depressions, including one that began the season in February and one that ended the season when it dissipated in December. Three storms intensified into hurricanes, two of which attained Category 2 status on the modern-day Saffir–Simpson Hurricane Scale. Storm data is largely based on the Atlantic hurricane database, which underwent a thorough revision for the period between 1911 and 1914 in 2005.
The 1908 Atlantic hurricane season was an active Atlantic hurricane season. Thirteen tropical cyclones formed, of which ten became tropical storms; six became hurricanes, and one of those strengthened into a major hurricane – tropical cyclones that reach at least Category 3 on the modern day Saffir–Simpson scale. The season's first system developed on March 6, and the last storm transitioned into an extratropical cyclone on October 23.
The 1903 Atlantic hurricane season featured seven hurricanes, the most in an Atlantic hurricane season since 1893. The first tropical cyclone was initially observed in the western Atlantic Ocean near Puerto Rico on July 21. The tenth and final system transitioned into an extratropical cyclone well northwest of the Azores on November 25. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Six of the ten tropical cyclones existed simultaneously.
The 1898 Atlantic hurricane season marked the beginning of the Weather Bureau operating a network of observation posts across the Caribbean Sea to track tropical cyclones, established primarily due to the onset of the Spanish–American War. A total of eleven tropical storms formed, five of which intensified into a hurricane, according to HURDAT, the National Hurricane Center's official database. Further, one cyclone strengthened into a major hurricane. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. The first system was initially observed on August 2 near West End in the Bahamas, while the eleventh and final storm dissipated on November 4 over the Mexican state of Veracruz.
The 1880 Atlantic hurricane season ran through the summer and fall of 1880. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1880 Atlantic season there were two tropical storms, seven hurricanes, and two major hurricanes (Category 3+). However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1880 cyclones, Hurricane Six was first documented in 1995 by José Fernández-Partagás and Henry Díaz. They also proposed large changes to the known tracks of several other storms for this year and 're-instated' Hurricane Ten to the database. A preliminary reanalysis by Michael Chenoweth, published in 2014, found thirteen storms, nine hurricanes, and four major hurricanes.
The 1886 Atlantic hurricane season ran through the early summer and the first half of fall in 1886. This is the period of each year when most tropical cyclones form in the Atlantic basin. It was a very active year, with ten hurricanes, six of which struck the United States, an event that would not occur again until 1985 and 2020. Four hurricanes became major hurricanes. However, in the absence of modern satellites and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea are known, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1886 cyclones, Hurricane Seven and Tropical Storm Eleven were first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large alterations to the known tracks of several other 1886 storms.
The 1888 Louisiana hurricane was a major hurricane that caused significant flooding and wind damage to the Mississippi River Delta and the Mississippi Valley in late August 1888. It was the third tropical cyclone and second hurricane of the 1888 Atlantic hurricane season.
