The following is a list of South-West Indian Ocean tropical cyclones before the year 1900, or 20th century.
| South-West Indian Ocean cyclone seasons |
On January 11, 1848, the first tropical cyclone on record was observed in the basin. [1]
1200 deaths - 50,000 homeless. The most dramatic and the most devastating cyclone in the history of the country. Sugar production fell 42%. A third of the city of Port Louis was destroyed in a few hours.
On February 4, a cyclone hit Vohemar in northeastern Madagascar, producing a minimum pressure of 972 mbar (28.7 inHg). [2]
The years before 1890 featured the pre-1890 North Indian Ocean cyclone seasons. Each season was an event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed.
The 1948 Pacific typhoon season was an average season. It had no official bounds; it ran year-round in 1948, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1900s Pacific hurricane seasons all began on May 15, 1900, in the northeast Pacific Ocean and on June 1, 1900, in the central Pacific. They ended on November 30, of each year. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean.
The 1935 Pacific hurricane season ran through the summer and fall of 1935. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. This season saw three tropical cyclones and ended early in August.
The 1925 Pacific hurricane season ran through the summer and fall of 1925. Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. 1925 season was the first Pacific hurricane season that was covered in detail by Monthly Weather Review, and this season included the most intense November Pacific hurricane on record until beaten by Hurricane Kenneth in 2011.
In the south-west Indian Ocean, tropical cyclones form south of the equator and west of 90° E to the coast of Africa.
The 1995–96 Australian region cyclone season was an active Australian cyclone season, with Western Australia experiencing a record number of landfalling intense storms in the Pilbara region. The season produced a total of 19 tropical cyclones, of which 14 developed into named storms and 9 reached severe tropical cyclone status. The strongest of the season was Severe Tropical Cyclone Olivia, which also produced the highest recorded wind gust on record of 408 km/h (253 mph). Though several systems impacted land, the general sparsity of population centres in Australia limits the scale of damage. One person was confirmed to have been killed and cumulative losses were estimated at A$77 million (US$58.5 million).
The 1941 Pacific typhoon season has no official bounds; it ran year-round in 1941, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1941 Pacific hurricane season. There were 28 tropical cyclones in the western Pacific in 1941.
The 1942 Pacific typhoon season has no official bounds; it ran year-round in 1942, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1942 Pacific hurricane season.
The 1944 Pacific typhoon season has no official bounds; it ran year-round in 1944, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1944 Pacific hurricane season.
The following is a list of tropical cyclones by year. Since the year 957, there have been at least 12,791 recorded tropical or subtropical cyclones in the Atlantic, Pacific, and Indian Oceans, which are known as basins. Collectively, tropical cyclones caused more than US$1.2 trillion in damage, unadjusted for inflation, and have killed more than 2.6 million people. Most of these deaths were caused by a few deadly cyclones, including the 1737 Calcutta cyclone, the 1839 Coringa cyclone, the 1931 Shanghai typhoon, the 1970 Bhola cyclone, Typhoon Nina in 1975, the 1991 Bangladesh cyclone, and Cyclone Nargis in 2008.
During 2004, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 132 systems formed with 82 of these developing further and were named by the responsible warning centre. The strongest tropical cyclone of the year was Cyclone Gafilo, which was estimated to have a minimum barometric pressure of 895 hPa (26.43 inHg). The most active basin in the year was the Western Pacific, which documented 29 named systems, while the North Atlantic, despite only amounting to 15 named systems, was the basin's most active season since 1996. Conversely, both the Eastern Pacific hurricane and North Indian Ocean cyclone seasons experienced the fewest cyclones reaching tropical storm intensity in recorded history, numbering 12 and 4, respectively. Activity across the southern hemisphere's three basins—South-West Indian, Australian, and South Pacific—was spread evenly, with each region recording seven named storms apiece. Throughout the year, 28 Category 3 tropical cyclones formed, including seven Category 5 tropical cyclones formed in the year.
The following is a list of North Indian Ocean tropical cyclones from 1900 to 1909. Records from before the 1970s were extremely unreliable, and storms that stayed at sea were often only reported by ship reports.
The following is a list of North Indian Ocean tropical cyclones from 1930 to 1939. Records from before the 1970s were extremely unreliable, and storms that stayed at sea were often only reported by ship reports.
The following is a list of North Indian Ocean tropical cyclones from 1910 to 1919. Records from before the 1970s were extremely unreliable, and storms that stayed at sea were often only reported by ship reports.
The following is a list of North Indian Ocean tropical cyclones from 1920 to 1929. Records from before the 1970s were extremely unreliable, and storms that stayed at sea were often only reported by ship reports.
