A tropical storm formed in mid-October. [1]
The 1956 Atlantic hurricane season featured a decent number of tropical cyclones, although most tropical storms and hurricanes affected land. There were twelve tropical storms, a third of which became hurricanes. One of the hurricanes strengthened to the equivalent of a major hurricane, which is a Category 3 or greater on the Saffir–Simpson scale. The strongest hurricane of the season was Betsy, which was also the most damaging storm of the season: it destroyed 15,000 houses and left $40 million in damage in Puerto Rico. Betsy was also the deadliest of the season, having killed 18 people in the French West Indies, two from a shipwreck in the Caribbean Sea, and 16 in Puerto Rico. Tropical Storm Dora struck Mexico in September and killed 27 people.
The 2003 Pacific hurricane season was the first season to feature no major hurricanes – storms of Category 3 intensity or higher on the Saffir–Simpson hurricane wind scale (SSHWS) – since 1977. The dates conventionally delimiting the period when most tropical cyclones form in the Pacific Ocean are May 15 in the Eastern Pacific Ocean and June 1 in the Central Pacific, with both seasons ending on November 30. The 2003 season featured 16 tropical storms between May 19 and October 26; 7 of these became hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.
The 1999 Pacific hurricane season was one of the least active Pacific hurricane seasons on record. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; in both basins, it ended on November 30. These dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season, Hurricane Adrian, developed on June 18, while the final storm of the season, Tropical Storm Irwin, dissipated on October 11. No storms developed in the Central Pacific during the season. However, two storms from the Eastern Pacific, Dora and Eugene, entered the basin, with the former entering as a hurricane.
The 1980 Pacific hurricane season officially started May 15, 1980, in the eastern Pacific and June 1, 1980, in the central Pacific, lasting until November 30, 1980. These dates conventionally delimit each year when most tropical cyclones form in the northeastern and central Pacific Ocean. This season was relatively uneventful; since no tropical cyclones made landfall, there were no reports of casualties or damage.
The 1955 Pacific hurricane seasons began on May 15, 1955, in the northeast Pacific Ocean and on June 1, 1955, in the central Pacific. They ended on November 30, 1955. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean.
A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern, central, and western, while the southern Pacific is divided into 2 sections, the Australian region and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.
The 1928 Pacific hurricane season ran through the summer and fall of 1928. 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.
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.
The 2010 Pacific hurricane season was the least active Pacific hurricane season since modern records, tied with 1977. The season saw only eight named storms, alongside a record-breaking low of three hurricanes. However, of those three, two of them became major hurricanes, and one hurricane, Celia, reached Category 5 intensity on the Saffir-Simpson scale. Also had the second-fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
The 1957 Pacific hurricane season was a moderately active year in which 13 tropical cyclones formed. The hurricane season ran through the summer and fall months which conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone developed on July 15. The final storm dissipated on December 6, becoming one of the few Pacific storms to exist outside of the seasonal dates. Of the season's 13 storms, five of these formed or crossed into the central Pacific.
The 2013 Pacific hurricane season was the first to see twenty named storms since 2009 but also had the ninth fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific. Both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin. However, the formation of a storm is possible at any time.
The 1958 Pacific hurricane season saw thirteen tropical systems. It officially started on May 15, 1958, in the eastern Pacific and lasted until November 30, 1958.
The 1954 Pacific hurricane season featured below-average activity, with eleven tropical storms identified. The season officially started on May 15 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. The majority of the year's storm remained offshore and caused little to no adverse impact on land. However, a tropical storm in October brought flooding rain to Mexico and Guatemala that left five people dead and thousands homeless. An unknown disease in the storm's wake killed a further 35 people.
The 1952 Pacific hurricane season ran through the summer and fall of 1952. Of the seven known tropical cyclones, all remained at sea.
During 2017, 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 146 tropical cyclones had formed. 88 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC).
The years between 1950 and 1959 featured the 1950s North Indian Ocean cyclone seasons. Each season was an ongoing 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. In this decade, only one RSMC watched over the basin at the time, India Meteorological Department (IMD) until 1959, when Joint Typhoon Warning Center (JTWC) was formed and it would release unofficial advisories for the basin.
