The 1964 Atlantic hurricane season featured the highest number of U.S.-landfalling hurricanes since 1933. The season officially began on June 15, 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 above average, with thirteen named storms, seven hurricanes, and five major hurricanes. The first system, an unnamed tropical storm, developed on June 2, almost two weeks before the official start of the season. Striking Florida on June 6, the storm brought localized flooding to portions of Cuba and the Southeastern United States, leaving about $1 million in damage. The next storm, also unnamed, developed near the end of July; it did not impact land.
The 1965 Atlantic hurricane season was the first to use the modern-day bounds for an Atlantic hurricane season, which are June 1 to November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a slightly below average season, with 10 tropical cyclones developing and reaching tropical storm intensity. Four of the storms strengthened into hurricanes. One system reached major hurricane intensity – Category 3 or higher on the Saffir–Simpson hurricane scale. The first system, an unnamed tropical storm, developed during the month of June in the southern Gulf of Mexico. The storm moved northward across Central America, but caused no known impact in the region. It struck the Florida Panhandle and caused minor impact across much of the Southern United States. Tropical cyclogenesis halted for over two months, until Anna formed on August 21. The storm remained well away from land in the far North Atlantic Ocean and caused no impact.
The 1975 Atlantic hurricane season was a near average hurricane season with nine named storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 or higher systems 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 Ocean.
Hurricane Donna, known in Puerto Rico as Hurricane San Lorenzo, was the strongest hurricane of the 1960 Atlantic hurricane season, and caused severe damage to the Lesser Antilles, the Greater Antilles, and the East Coast of the United States, especially Florida, in August–September. The fifth tropical cyclone, third hurricane, and first major hurricane of the season, Donna developed south of Cape Verde on August 29, spawned by a tropical wave to which 63 deaths from a plane crash in Senegal were attributed. The depression strengthened into Tropical Storm Donna by the following day. Donna moved west-northwestward at roughly 20 mph (32 km/h) and by September 1, it reached hurricane status. Over the next three days, Donna deepened significantly and reached maximum sustained winds of 130 mph (210 km/h) on September 4. Thereafter, it maintained intensity as it struck the Lesser Antilles later that day. On Sint Maarten, the storm left a quarter of the island's population homeless and killed seven people. An additional five deaths were reported in Anguilla, and there were seven other fatalities throughout the Virgin Islands. In Puerto Rico, severe flash flooding led to 107 fatalities, 85 of them in Humacao alone.
The 1952 Atlantic hurricane season was the last Atlantic hurricane season in which tropical cyclones were named using the Joint Army/Navy Phonetic Alphabet. It was a near normal Atlantic hurricane season, although it was the least active since 1946. The season officially started on June 15; however, a pre-season unnamed storm formed on Groundhog Day, becoming the only storm on record in the month of February. The other six tropical cyclones were named using the Joint Army/Navy Phonetic Alphabet, the first of which formed on August 18. The final storm of the season dissipated on October 28, two and a half weeks before the season officially ended on November 15.
The 1945 Atlantic hurricane season produced multiple landfalling tropical cyclones. It officially began on June 16 and lasted until October 31, dates delimiting the period when a majority of storms were perceived to form in the Atlantic Ocean. A total of 11 systems were documented, including a late-season cyclone retroactively added a decade later. Five of the eleven systems intensified into hurricanes, and two further attained their peaks as major hurricanes. Activity began with the formation of a tropical storm in the Caribbean on June 20, which then made landfalls in Florida and North Carolina at hurricane intensity, causing one death and at least $75,000 in damage. In late August, a Category 3 hurricane on the modern-day Saffir–Simpson hurricane wind scale struck the Texas coastline, with 3 deaths and $20.1 million in damage. The most powerful hurricane of the season, reaching Category 4 intensity, wrought severe damage throughout the Bahamas and East Coast of the United States, namely Florida, in mid-September; 26 people were killed and damage reached $60 million. A hurricane moved ashore the coastline of Belize in early October, causing one death, while the final cyclone of the year resulted in 5 deaths and $2 million in damage across Cuba and the Bahamas two weeks later. Overall, 36 people were killed and damage reached at least $82.85 million.
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 1943 Atlantic hurricane season marked the first deliberate reconnaissance aircraft flights into tropical cyclones. The season officially lasted from June 16 to October 31, which was, at the time, considered the most likely period for tropical cyclone formation in the Atlantic Ocean. A total of ten storms from 1943 are listed in the Atlantic hurricane database, and an eleventh system that affected Florida and Georgia has been identified as a probable tropical depression. The first system of the year, dubbed the "Surprise hurricane", caused severe damage throughout Texas and Louisiana in June, partially because information about its approach was censored in the fray of World War II; the storm caused 19 deaths and $17 million in damage. A major hurricane in mid-August produced hurricane-force winds in Bermuda, and several other tropical cyclones throughout the year resulted in strong winds there. In September, a hurricane impacted the western Gulf Coast of the United States, then a tropical storm struck the Mid-Atlantic. The two storms resulted in $419,000 and $20,000 in damage, respectively; one death was attributed to the latter system. In mid-October, a strong hurricane resulted in flooding and damage to crops throughout the Caribbean; after becoming post-tropical, it contributed to moderate impacts across Nova Scotia.
The 1923 Atlantic hurricane season featured 11 tropical cyclones, 9 of which intensified into tropical storms, the most since 1916. Four of the tropical storms intensified into hurricanes, one of which reached major hurricane intensity—Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. No tropical storms or hurricanes formed in or entered the Caribbean Sea. The first known system, a tropical depression, formed on June 19, while the last known system, a tropical storm, transitioned into an extratropical cyclone on October 26. A total of Additionally, an October tropical depression was previously recognized as a tropical storm until reanalysis in 2009, while the first and third tropical storms were added to the Atlantic hurricane database that year. The sixth, seven, and eight storms as well as the October tropical depression existed simultaneously on October 16.
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 1944 Great Atlantic hurricane was a destructive and powerful tropical cyclone that swept across a large portion of the United States East Coast in September 1944. New England was most affected, though so were the Outer Banks, Mid-Atlantic states, and the Canadian Maritimes. The storm's ferocity and path drew comparisons to the 1938 Long Island Express, one of the worst storms in New England history.
The 1896 Atlantic hurricane season was fairly inactive but produced one of the costliest hurricanes ever to strike the United States until that point, along with several other destructive tropical cyclones. The season began in early July with a hurricane in the Gulf of Mexico and ended in late November with a slow-moving tropical storm over the Lesser Antilles. Of the season's seven documented systems, six are believed to have become hurricanes, and two intensified into major hurricanes—the equivalence of Category 3 or greater on the modern-day Saffir–Simpson scale. All but one of the systems directly affected land to some degree; Hurricane "Six" remained over open water and only posed a threat to shipping lanes. In addition, a possible storm was identified off the coast of North Carolina on August 28–29, but modern reanalysis efforts have found insufficient evidence to classify it as a tropical cyclone. Tropical systems in the 1896 season killed at least 286 people and inflicted more than $10 million in damage.
Hurricane Dennis caused flooding in North Carolina and the Mid-Atlantic states in early September 1999, which would later be compounded by Hurricane Floyd. The fifth tropical cyclone of the season, Dennis developed from a tropical wave to the north of Puerto Rico on August 24. Originally a tropical depression, the system moved west-northwestward and strengthened into a tropical storm despite unfavorable wind shear. The storm became a hurricane by August 26. After striking the Abaco Islands, conditions improved, allowing for Dennis to strengthen into a Category 2 on the Saffir–Simpson scale by August 28. Around this time, Dennis began to move parallel to the Southeastern United States. Early on August 30, the storm peaked with winds of 105 mph (165 km/h). By the following day, steering currents collapsed and the storm interacted with a cold front, causing Dennis to move erratically offshore North Carolina. Wind shear and cold air associated with the front weakened Dennis to a tropical storm on September 1 and removed some of its tropical characteristics. Eventually, warmer ocean temperatures caused some re-strengthening. By September 4, Dennis turned northwestward and made landfall in Cape Lookout, North Carolina, as a strong tropical storm. The storm slowly weakened inland, before transitioning into an extratropical cyclone over western New York on September 7.
Hurricane Esther was the first large tropical cyclone to be discovered by satellite imagery. The fifth tropical cyclone, named storm, and hurricane of the 1961 Atlantic hurricane season, Esther developed from an area of disturbed weather hundreds of miles west-southwest of the southernmost Cape Verde Islands on September 10. Moving northwestward, the depression strengthened into Tropical Storm Esther on September 11, before reaching hurricane intensity on the following day. Early on September 13, Esther curved westward and deepened into a major hurricane. The storm remained a Category 3 hurricane for about four days and gradually moved in a west-northwestward direction. Late on September 17, Esther strengthened into a Category 5 hurricane with sustained winds of 160 mph (260 km/h) on September 18. The storm curved north-northeastward on September 19, while offshore of North Carolina. Esther began to weaken while approaching New England and fell to Category 3 intensity on September 21. The storm turned eastward early on the following day, and rapidly weakened to a tropical storm.
Tropical Storm Josephine was an unusual Atlantic tropical storm that moved from west to east across the Gulf of Mexico in October 1996. It formed on October 4 as a tropical depression from the remnants of a cold front. Early in its duration, the system interacted with a ridge over the central United States, which produced strong winds and high tides along the Texas coast. The outer rainbands caused flooding rainfall in southern Texas, and in Louisiana, high tides flooded roads and stranded residents on Grand Isle. Moving generally to the east due to a trough, the depression intensified into a tropical storm on October 6, and the next day reached peak winds of 70 mph (110 km/h) while approaching the west coast of Florida. Josephine made landfall in Taylor County near peak intensity early on October 8, and soon after became extratropical. While moving ashore, the storm produced a high storm surge reaching 9.3 ft (2.8 m) in Suwannee. High tides flooded about 3,600 houses along the west coast. Josephine also produced heavy rainfall, which flooded hundreds of homes, and high winds, which left 400,000 people without power. The storm also spawned at least 16 tornadoes, one of which damaged 130 homes.
The 1945 Homestead hurricane, known informally as Kappler's hurricane, was the most intense tropical cyclone to strike the U.S. state of Florida since 1935. The ninth tropical storm, third hurricane, and third major hurricane of the season, it developed east-northeast of the Leeward Islands on September 12. Moving briskly west-northwestward, the storm became a major hurricane on September 13. The system moved over the Turks and Caicos Islands the following day and then Andros on September 15. Later that day, the storm peaked as a Category 4 hurricane on the modern-day Saffir–Simpson scale with winds of 130 mph (215 km/h). Late on September 15, the hurricane made landfall on Key Largo and then in southern Dade County, Florida.
The 1924 Atlantic hurricane season featured the first officially recorded Category 5 hurricane, a tropical cyclone with maximum sustained winds exceeding 155 mph (249 km/h) on the modern-day Saffir–Simpson scale. The first system, Tropical Storm One, was first detected in the northwestern Caribbean Sea on June 18. The final system, an unnumbered tropical depression, dissipated on November 24. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Of the 13 tropical cyclones of the season, six existed simultaneously. The season was average with 11 tropical storms, five of which strengthened into hurricanes. Further, two of those five intensified into major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale.
Subtropical Storm Four brushed Florida and The Bahamas in October 1974. The eighteenth cyclone and fourth subtropical storm of the 1974 Atlantic hurricane season, the storm developed near eastern Cuba on October 4 from an area of disturbed weather. Shortly before striking Andros Island on October 6, the system strengthened into a subtropical storm. The storm made its closest approach to Florida early on October 7. Peaking with sustained winds of 50 mph (85 km/h), the system veered northward and then northeastward, but nonetheless caused heavy rainfall and coastal flooding on land in Florida. While paralleling offshore North Carolina and South Carolina, the storm began to slowly weaken. By late on October 8, the subtropical cyclone merged with a cold front while well east of Cape Hatteras.
The 1896 Cedar Keys hurricane was a powerful and destructive tropical cyclone that devastated much of the East Coast of the United States, starting with Florida's Cedar Keys, near the end of September 1896. The storm's rapid movement allowed it to maintain much of its intensity after landfall and cause significant damage over a broad area; as a result, it became one of the costliest United States hurricanes at the time. The fourth tropical cyclone of the 1896 Atlantic hurricane season, it formed by September 22, likely from a tropical wave, before crossing the Caribbean Sea just south of the Greater Antilles. It entered the Gulf of Mexico as the equivalent of a major hurricane on the Saffir–Simpson scale, and struck the Cedar Keys—an offshore island chain that includes the island and city of Cedar Key—early on the morning of September 29 with winds of 125 mph (205 km/h). The area was inundated by a devastating 10.5 ft (3.2 m) storm surge that undermined buildings, washed out the connecting railroad to the mainland, and submerged the smaller, outlying islands, where 31 people were killed. Strong winds also destroyed many of the red cedar trees that played an important role in the economy of the region. No hurricane would hit this region of Florida with a similar strength until 2023.
