The 1930 Atlantic hurricane season was the second least active Atlantic hurricane season on record in terms of tropical storms formed, only behind 1914, with only three systems reaching tropical storm intensity. Of those three, two reached hurricane status, both of which also became major hurricanes, Category 3 or higher storms on the Saffir–Simpson hurricane wind scale. The first system developed in the central Atlantic Ocean on August 21. Later that month, a second storm, the Dominican Republic hurricane, formed on August 29. It peaked as a Category 4 hurricane with winds of 155 mph (250 km/h). The third and final storm dissipated on October 21.
The 1906 Atlantic hurricane season was an average season. It featured twelve tropical cyclones, eleven of which became storms, six became hurricanes and three became major hurricanes. The first storm of the season, a tropical storm in the northern Caribbean, formed on June 8; although it struck the United States, no major impacts were recorded. July saw a period of inactivity, with no known storms. However, in August, the streak of inactivity ended with two storms, including a powerful hurricane. September brought three storms, including a deadly hurricane, with catastrophic impacts in Pensacola and Mobile. October included three storms, with a powerful hurricane that killed over 200 people. The final storm of the season impacted Cuba in early November and dissipated on November 9. The season was quite deadly, with at least with 381 total recorded deaths.
The 1905 Atlantic hurricane season featured five known tropical cyclones, two of which made landfall in the United States. The first system was initially observed near the Windward Islands on September 6. The last system to dissipate, the fourth storm, transitioned into an extratropical cyclone on October 11, while located well southeast of Newfoundland. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Between October 5 and October 10, the fourth and fifth system existed simultaneously.
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 1901 Atlantic hurricane season was the most active season without a major hurricane – tropical cyclones that reach at least Category 3 on the Saffir–Simpson hurricane wind scale – until 2013. The first system was initially observed in the northeastern Caribbean on June 11. The fourteenth and final system transitioned into an extratropical cyclone near Bermuda on November 5. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Eight of the fourteen tropical cyclones existed simultaneously.
The 1899 Atlantic hurricane season featured the longest-lasting tropical cyclone in the Atlantic basin on record. There were nine tropical storms, of which five became hurricanes. Two of those strengthened into major hurricanes, which are Category 3 or higher on the modern day Saffir–Simpson hurricane wind scale. The first system was initially observed in the northeastern Gulf of Mexico on June 26. The tenth and final system dissipated near Bermuda on November 10. These dates fall within the period with the most tropical cyclone activity in the Atlantic. In post-season analysis, two tropical cyclones that existed in October were added to HURDAT – the official Atlantic hurricane database. At one point during the season, September 3 through the following day, a set of three 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 1897 Atlantic hurricane season was an inactive season, featuring only six known tropical cyclones, four of which made landfall. There were three hurricanes, none of which strengthened into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. The first system was initially observed south of Cape Verde on August 31, an unusually late date. The storm was the strongest of the season, peaking as a Category 2 hurricane with winds of 100 mph (155 km/h). While located well north of the Azores, rough seas by the storm sunk a ship, killing all 45 crewmen. A second storm was first spotted in the Straits of Florida on September 10. It strengthened into a hurricane and tracked northwestward across the Gulf of Mexico, striking Louisiana shortly before dissipating on September 13. This storm caused 29 deaths and $150,000 (1897 USD) in damage.
The 1892 Atlantic hurricane season included the last tropical cyclone on record to pass through the Cabo Verde Islands at hurricane intensity until 2015. A total of nine tropical storms developed, five of which strengthened into a hurricane, though none of them became 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. Three tropical storms made landfall on the United States.
The 1884 Atlantic hurricane season was one of only three Atlantic hurricane seasons, along with 1852 and 1858, in which every known tropical cyclone attained hurricane status. Overall, four tropical cyclones developed, three of which made landfall. The first system was initially observed over the northwestern Atlantic Ocean on September 1. It struck Newfoundland the following day, but impact there is unknown. On September 3, the next hurricane developed, though it did not affect land in its duration. The third hurricane struck Georgia, accompanied by damaging waves in north Florida.
The 1870 Atlantic hurricane season marked the beginning of Father Benito Viñes investigating tropical cyclones, inspired by two hurricanes that devastated Cuba that year; Viñes consequently became a pioneer in studying and forecasting such storms. The season featured 11 known tropical cyclones, 10 of which became a hurricane, while 2 of those intensified into 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.
The 1883 Atlantic hurricane season ran through the summer and the first half of fall in 1883. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1883 Atlantic season there was one tropical storm, one Category 1 hurricane, and two major hurricanes. However, in the absence of modern satellite monitoring and 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 1881 Atlantic hurricane season ran through the summer and early fall of 1881. This is the period of each year when most tropical cyclones form in the Atlantic basin. In the 1881 Atlantic season there were three tropical storms and four hurricanes, none of which became 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 1881 cyclones, Hurricane Three and Tropical Storm Seven were both first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed changes to the known tracks of Hurricane Four and Hurricane Five.
The 1877 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that in 1877 there were eight cyclones, of which five were tropical storms and three were hurricanes, one of which became 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 1876 Atlantic hurricane season featured the first hurricane landfall in North Carolina since 1861. Overall, the season was relatively quiet, with five tropical storms developing. Four of these became a hurricane, of which two intensified into major hurricanes. However, due to the absence of remote-sensing satellite and other technology, only storms that affected populated land areas or encountered ships at sea were recorded; therefore, 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 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 1873 Atlantic hurricane season was quiet, featuring only five known tropical cyclones, but all of them made landfall, causing significant impacts in some areas of the basin. Of these five systems, three intensified into a hurricane, while two of those attained major hurricane status. 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 1872 Atlantic hurricane season included a storm whose track became one of the first to be published by the United States Army Signal Service, a predecessor of the National Weather Service. The season was quiet, with only five documented tropical cyclones, of which four attained hurricane status. None of them intensified 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 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 1859 Atlantic hurricane season featured seven hurricanes, the most recorded during an Atlantic hurricane season until 1870. 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. Of the eight known 1859 cyclones, five were first documented in 1995 by Jose Fernandez-Partagás and Henry Diaz, which was 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. HURDAT is the official source for hurricane data such as track and intensity, although due to sparse records, listings on some storms are incomplete.
