The 1977 Atlantic hurricane season was a very inactive Atlantic hurricane season, with only six named storms. The season officially began on Wednesday, June 1, 1977 and lasted until Wednesday, November 30, 1977. These dates conventionally delimit the period of each year when most tropical cyclogenesis occurs in the Atlantic basin. The first tropical cyclone of the season developed over the western Caribbean Sea on June 13, 12 days after the start of the season. Three more organized during July and early August. Then, on August 29, the first named storm, Hurricane Anita formed and rapidly intensified to a Category 5 hurricane on September 1, before weakening slightly and striking Mexico as a high-end Category 4 hurricane on the Saffir–Simpson hurricane wind scale, bringing strong winds and heavy rainfall, causing 11 fatalities and leaving at least 25,000 people homeless.
The 1959 Escuminac disaster, also known as the Escuminac hurricane, was considered the worst fishing-related disaster in New Brunswick in 100 years. It occurred due to the extratropical remnants of an Atlantic hurricane. The storm was the third tropical cyclone and first hurricane of the 1959 Atlantic hurricane season, and developed from a tropical wave in the central Gulf of Mexico on June 18. It headed rapidly northeastward and struck Florida later that day. Shortly after entering the Atlantic Ocean, it strengthened into a tropical storm later on June 18. By the following day, it had strengthened into a hurricane. However, it transitioned into an extratropical cyclone about six hours later. The remnants struck Atlantic Canada, once in Nova Scotia and again in Newfoundland before dissipating on June 21.
The 1937 Atlantic hurricane season was a below-average hurricane season, featuring eleven tropical storms; of these, four became hurricanes. One hurricane reached major hurricane intensity, equivalent to a Category 3 or higher on the modern Saffir–Simpson scale. The United States Weather Bureau defined the season as officially lasting from June 16 to October 16. 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. As a result of a reanalysis project which analyzed the season in 2012, a tropical storm and a hurricane were added to the Atlantic hurricane database (HURDAT). The official intensities and tracks of all storms were also revised by the reanalysis. The year's first storm formed on July 29 in the Gulf of Mexico, and the final system, a hurricane, dissipated over open ocean on October 21.
The 1927 Atlantic hurricane season was a relatively inactive season, with eight tropical storms, four of which became hurricanes. One of these became a major hurricane – Category 3 or higher on the modern day Saffir–Simpson scale. The first system, a tropical depression, developed on August 13, while the final cyclone, a tropical storm, merged with a cold front on November 21. No hurricane made landfall in the United States, in contrast to the four that struck the U.S. in the previous season.
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 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 1904 Atlantic hurricane season featured no tropical cyclones during the months of July and August. The season's first cyclone was initially observed in the southwestern Caribbean on June 10. After this storm dissipated on June 14, the next was not detected until September 8. The sixth and final system transitioned into an extratropical cyclone offshore South Carolina on November 4. Two of the six tropical cyclones existed simultaneously.
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.
Hurricane Helene was the most intense tropical cyclone of the 1958 Atlantic hurricane season. The eighth tropical storm and fourth hurricane of the year, Helene was formed from a tropical wave east of the Lesser Antilles. Moving steadily westward, the storm slowly intensified, attaining hurricane strength on September 26. As conditions became increasingly favorable for tropical cyclone development, Helene began to rapidly intensify. Nearing the United States East Coast, the hurricane quickly attained Category 4 intensity on September 26, before it subsequently reached its peak intensity with maximum sustained winds of 150 mph (240 km/h) and a minimum barometric pressure of 930 mbar. The intense hurricane came within 10 mi (16 km) of Cape Fear, North Carolina before recurving out to sea. Accelerating Helene gradually weakened, and transitioned into an extratropical cyclone as it passed over Newfoundland on September 29. Helene's extratropical remnants traversed eastwards across the Atlantic Ocean before dissipating near Great Britain on October 4.
Hurricane Gladys was a tropical cyclone that caused minor impact along the East Coast of the United States, Bermuda, and Atlantic Canada. The ninth named storm and fifth hurricane of the 1964 Atlantic hurricane season, Gladys developed from a tropical wave located east of the Lesser Antilles on September 13. Shortly thereafter, it strengthened into a tropical storm. On September 14, Gladys abruptly intensified into a Category 2 hurricane on the Saffir–Simpson hurricane wind scale. However, early on the following day, Gladys weakened slightly to a Category 1 hurricane. Between late on September 16 and late on September 17, the storm rapidly strengthened, peaking as a 145 mph (233 km/h) Category 4 hurricane on the latter. Gladys began weakening on the following day and curved northward on September 19.
The 1933 Chesapeake–Potomac hurricane was among the most damaging hurricanes in the Mid-Atlantic states in the eastern United States. The sixth storm and third hurricane of the very active 1933 Atlantic hurricane season, it formed in the eastern Atlantic, where it moved west-northwestward and eventually became a Category 4 on the Saffir-Simpson hurricane wind scale. A strong ridge over New England allowed a continued northwest course, bringing the storm south of Bermuda and later toward the middle coast of the eastern United States. Advanced warning allowed hundreds of people to evacuate ahead of the hurricane making landfall. It did so in northeastern North Carolina on August 23 with winds of about 90 mph (140 km/h). Soon after, the eye crossed over Norfolk, Virginia, the first time that happened since 1821. The hurricane weakened into a tropical storm over northern Virginia shortly before passing near Washington, D.C., becoming the worst tropical cyclone there since 1896. Curving northward, the storm moved through Pennsylvania and New York before losing tropical characteristics on August 25. Now extratropical, the former hurricane moved across Atlantic Canada, dissipating on August 28.
Hurricane Daisy brought the worst flooding to New England since Hurricane Diane in 1955. The fourth named storm and second hurricane of the 1962 Atlantic hurricane season, Daisy developed from a tropical disturbance located well east of the Leeward Islands on September 29. Initially a tropical depression, it headed west-northwestward and failed to strengthen significantly. While located a short distance from the Leeward Islands, the depression curved northwestward and began intensifying. On October 2, the depression was upgraded to Tropical Storm Daisy. Around that time, the storm turned back to the west-northwest and continued to deepen. Daisy reached hurricane status late on October 3. Two days later, it became a Category 2 hurricane on the Saffir–Simpson hurricane wind scale, but briefly weakened back to a Category 1 on October 6.
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.
The 1879 Atlantic hurricane season ran from the summer to near the end of autumn in 1879. In 1879 there were two tropical storms, four hurricanes, and two major hurricanes. 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 1879 cyclones, Hurricane One were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large changes to the known tracks of Hurricanes Two, Three, Seven and Eight. Later one storm was deemed not to be a tropical cyclone at all and was dropped from the database.
The 1875 Atlantic hurricane season featured three landfalling tropical cyclones. 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 has been estimated. There were five recorded hurricanes and one major hurricane – Category 3 or higher on the modern-day Saffir–Simpson scale.
The 1871 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that 1871 featured two tropical storms, four hurricanes and two major hurricanes. 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. According to a study in 2004, 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 is possible. A later study in 2008 estimated that eight or more storms may have been missed prior to 1878.
Hurricane Carol was the strongest storm of the 1953 Atlantic hurricane season and the first Category 5 hurricane in the Atlantic basin since the 1944 Great Atlantic Hurricane. Carol was also the first named storm to attain Category 5 status. Carol developed on August 28 off the west coast of Africa, although the Weather Bureau did not initiate advisories until five days later. On September 2, Carol attained hurricane status, based on a ship report. It moved northwestward, attaining peak winds of 160 mph (260 km/h), based on reports from the Hurricane Hunters. After weakening, it brushed Bermuda and turned northeastward near New England, passing west of Nova Scotia before making landfall near Saint John, New Brunswick on September 7. While crossing Atlantic Canada, Carol became an extratropical cyclone, which dissipated on September 9 southwest of Greenland.
The 1863 Atlantic hurricane season featured five landfalling tropical cyclones. 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 has been estimated. There were seven recorded hurricanes and no major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson scale. Of the known 1863 cyclones, seven were first documented in 1995 by José Fernández-Partagás and Henry Diaz, while the ninth tropical storm was first documented in 2003. These changes were largely adopted by the National Oceanic and Atmospheric Administration's Atlantic hurricane reanalysis in their updates to the Atlantic hurricane database (HURDAT), with some adjustments.
The 1940 Nova Scotia hurricane swept through areas of Atlantic Canada in mid-September 1940. The fifth tropical cyclone and fourth hurricane of the year, it formed as a tropical depression east of the Lesser Antilles on September 7, though at the time weather observations in the area were sparse, so its formation was inferred. The disturbance gradually intensified throughout much of its early formative stages, attaining tropical storm strength on September 10; further strengthening into a hurricane north of Puerto Rico occurred two days later. Shortly thereafter, the hurricane recurved northward, and reached peak intensity the following day as a Category 2 hurricane with maximum sustained winds of 100 mph (160 km/h) and a minimum barometric pressure of at least 988 mbar. The cyclone steadily weakened thereafter before making landfall on Nova Scotia on September 17 with winds of 85 mph (135 km/h). Moving into the Gulf of Saint Lawrence later that day, the storm transitioned into an extratropical cyclone. The remnant system curved eastward and passed over Newfoundland before dissipating over the Atlantic on September 19.
The 1926 Nova Scotia hurricane was one of the deadliest Canadian hurricanes in the 20th century. The second tropical cyclone and second hurricane of the season, the storm developed from a trough situated well east of the Leeward Islands on July 29. Over the next few days, it moved west-northwest, becoming a tropical storm by July 31. The cyclone turned to the northwest on August 1 and began strengthening rapidly, reaching hurricane intensity by the early afternoon. The next day, it became a major hurricane—equivalent to Category 3 intensity on the modern-day Saffir–Simpson hurricane wind scale. Over the next few days, the storm's track varied between north-northwest and northwest. Early on August 5, it peaked with winds of 120 mph (190 km/h). The hurricane then began weakening as it curved northward. The storm began losing tropical characteristics while approaching Atlantic Canada, transitioning into an extratropical cyclone on August 8. The remnants soon made landfall near Port Hawkesbury, Nova Scotia, with winds of 75 mph (121 km/h), before being last noted over Newfoundland later that day.
