The Great Hurricane of 1780 was the deadliest Atlantic hurricane on record, as well as the deadliest tropical cyclone in the Western Hemisphere. An estimated 22,000 people died throughout the Lesser Antilles when the storm passed through the islands from October 10 to October 16. Specifics on the hurricane's track and strength are unknown, as the official Atlantic hurricane database only goes back to 1851.
The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage and a total of 51 deaths across the Mid-Atlantic region of the United States.
Tropical Storm Odette was a rare off-season tropical cyclone that hit the island of Hispaniola in early December 2003. As the fifteenth named storm of the 2003 Atlantic hurricane season, Odette formed near the coast of Panama a few days after the official end of the Atlantic hurricane season ended on November 30, and ultimately made landfall on the Dominican Republic as a moderate tropical storm, before becoming extratropical on December 7, dissipating two days later.
The 1910 Atlantic hurricane season was a fairly inactive season, with only five storms. Three of those systems, however, grew into hurricanes and one became a major hurricane. The season got off to a late start with the formation of a tropical storm in the Caribbean Sea on August 23. September saw two storms, and the final tropical cyclone—Hurricane Five—existed during October. All but one of the storms made landfall, and the only cyclone which remained at sea had some effects on the island of Bermuda.
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 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 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 decade of the 1820s featured the 1820s Atlantic hurricane seasons. While data is not available for every storm that occurred, some parts of the coastline were populated enough to give data of hurricane occurrences. Each season was an ongoing event in the annual cycle of tropical cyclone formation in the Atlantic basin. Most tropical cyclone formation occurs between June 1 and November 30.
The decade of the 1830s featured the 1830s Atlantic hurricane seasons. While data is not available for every storm that occurred, some parts of the coastline were populated enough to give data of hurricane occurrences. Each season was an ongoing event in the annual cycle of tropical cyclone formation in the Atlantic basin. Most tropical cyclone formation occurs between June 1 and November 30.
This article encompasses the 1840–1849 Atlantic hurricane seasons. While data is not available for every storm that occurred, some parts of the coastline were populated enough to give data of hurricane occurrences. Each season was an ongoing event in the annual cycle of tropical cyclone formation in the Atlantic basin. Most tropical cyclone formation occurs between June 1 and November 30.
The decade of the 1800s featured the 1800s Atlantic hurricane seasons. While data is not available for every storm that occurred, some parts of the coastline were populated enough to give data of hurricane occurrences. Each season was an ongoing event in the annual cycle of tropical cyclone formation in the Atlantic basin. Most tropical cyclone formation occurs between June 1 and November 30.
The 1780 Atlantic hurricane season ran through the summer and fall in 1780. The 1780 season was extraordinarily destructive, and was the deadliest Atlantic hurricane season in recorded history, with over 28,000 deaths. Four different hurricanes, one in June and three in October, caused at least 1,000 deaths each; this event has never been repeated, and only in the 1893 and 2005 seasons were there two such hurricanes. The season also had the deadliest Atlantic hurricane of all time, the Great Hurricane of 1780. Only one of the known storms was not a hurricane.
The 1851 Atlantic hurricane season was the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record. Six known tropical cyclones occurred during the season, the earliest of which formed on June 25 and the latest of which dissipated on October 19. These dates fall within the range of most Atlantic tropical cyclone activity. None of the cyclones existed simultaneously with another. Three of the six storms only have a single point in their track known.
The 1852 Atlantic hurricane season was one of only three Atlantic hurricane seasons in which every known tropical cyclone attained hurricane status. Five tropical cyclones were reported during the season, which lasted from late August through the middle of October; these dates fall within the range of most Atlantic tropical cyclone activity, and none of the cyclones coexisted with another. Though there were officially five tropical cyclones in the season, hurricane scholar Michael Chenoweth assessed two of the cyclones as being the same storm. There may have been other unconfirmed tropical cyclones during the season, as meteorologist Christopher Landsea estimated that up to six storms were missed each year from the official database; this estimate was due to small tropical cyclone size, sparse ship reports, and relatively unpopulated coastlines.
The 1878 Atlantic hurricane season lasted from the summer through much of the fall. Records show that 1878 featured a relatively active hurricane season. A total of twelve storms were observed during the year. There were twelve tropical storms, eight 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 1878 cyclones, both Hurricane Three and Hurricane Four were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz, who also proposed large changes to the known tracks of Hurricanes Two, Seven and Eight. Further analysis from 2000 onwards extended the duration of Hurricane Three by one day and identified major track changes for Hurricane Five.
The 1876 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that 1876 featured a relatively inactive hurricane season. There were five tropical storms, four became hurricanes, two of which became 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. Of the known 1876 cyclones, both Hurricane One and Hurricane Four were first documented in 1995 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large changes to the known tracks of Hurricane Two and of Hurricane Five. The track and start position of Hurricane Five was further amended in 2003.
The 2019 Atlantic hurricane season was the fourth consecutive above-average and damaging season dating back to 2016. However, many storms were weak and short-lived, especially towards the end of the season. Six of those named storms achieved hurricane status, while three intensified into major hurricanes. Two storms became Category 5 hurricanes, marking the fourth consecutive season with at least one Category 5 hurricane, the third consecutive season to feature at least one storm making landfall at Category 5 intensity, and the seventh on record to have multiple tropical cyclones reaching Category 5 strength. The season officially began on June 1 and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the formation of Subtropical Storm Andrea on May 20, making this the fifth consecutive year in which a tropical or subtropical cyclone developed outside of the official season.
The 1850 Atlantic hurricane season was the last season excluded from the scope of the official Atlantic hurricane database. Although meteorological records are sparse and generally incomplete, they indicate that three significant tropical cyclones affected land, each causing some degree of damage. The first system struck North Carolina on July 18, causing significant damage before battering the Mid-Atlantic states with high tides, strong winds, and heavy rainfall. Torrential rainfall caused river flooding from Baltimore to Philadelphia, particularly along the Schuylkill River, which took the lives of 20 people in various incidents. Strong winds damaged property and public facilities in and around New York City, and damaging floods extended into central and northern New England. Crops and railroad infrastructure suffered throughout the entire region.
The 1842 Atlantic hurricane season featured several maritime catastrophes in the Gulf of Mexico and along the U.S. East Coast, and produced one of the only known tropical cyclones to directly affect the Iberian Peninsula. As the season falls outside the scope of the Atlantic hurricane database, records of most storms in 1842 are scarce, and only approximate tracks are known. The first documented storm of the season battered the coast of North Carolina in mid-July, wrecking dozens of ships and destroying homes along the Outer Banks. A little over a month later, another storm impacted the same region and caused several more shipwrecks that killed at least 12 men. This storm later doused the Mid-Atlantic states with flooding rains. In early September, a powerful storm known as "Antje's Hurricane"—named after a ship that it dismasted—tracked generally westward after first being spotted over the Leeward Islands. After yielding widespread destruction across the Bahamas, the storm traversed the Florida Straits, causing severe damage in both northern Cuba and the lower Florida Keys. Many ships and their crews were lost to the storm as it crossed the Gulf of Mexico; it finally struck northern Mexico on September 8.
