Cyclone Anne Severe Tropical Cyclone Anne was one of the most intense tropical cyclones within the South Pacific basin during the 1980s. The cyclone was first noted on January 5, 1988 as a weak tropical depression to the northeast of Tuvalu, in conjunction with the future Typhoon Roy in the North-Western Pacific basin. Over the next few days, the system gradually developed while moving southwestward. Once it became a tropical cyclone, it was named Anne on January 8. The next day, Anne rapidly intensified, becoming the fourth major tropical cyclone to affect Vanuatu within four years. On January 11, Anne peaked in intensity while it was equivalent to a Category 5 on the Saffir–Simpson hurricane wind scale, and a Category 4 on the Australian tropical cyclone intensity scale. After turning southward on January 12, Anne struck New Caledonia, becoming the strongest tropical cyclone to affect the French Overseas Territory. The system subsequently weakened as it started to interact with Tropical Cyclone Agi. Anne weakened into a depression and was last noted on January 14 to the south-east of New Caledonia.

Typhoon A typhoon is a mature tropical cyclone that develops in the western part of the North Pacific Ocean between 180° and 100°E. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140° to 180°W), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines and Hong Kong. While the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Only the Philippines use their own naming list for systems approaching the country.

2010 Pacific hurricane season The 2010 Pacific hurricane season is the least active Pacific hurricane season, alongside 1977, since reliable records began in 1971. It officially started on May 15, 2010 for the eastern Pacific, and June 1, 2010 for the central Pacific, and officially ended on November 30, 2010. Unlike the 2009 season, the first storm of the 2010 season, Agatha, formed during the month of May. It developed on May 29 near the coast of Guatemala. In the second week of June, a sudden spree of tropical cyclones developed, and between June 16 and 22, four cyclones formed, including the two major hurricanes of the season, Celia and Darby, the first of which reached Category 5 intensity. However, following the record active June, July saw zero named storms. In August and September only 2 tropical storms and one hurricane formed. Tropical Depression Eleven-E caused a great deal of flooding in southern Mexico, causing millions of dollars in damage and causing over 50 deaths and $500 million in damage in areas of Oaxaca and Guatemala. Tropical Storm Omeka was a rare off-season storm.

Tropical Storm Thelma Tropical Storm Thelma, known in the Philippines as Tropical Storm Uring, was one of the deadliest tropical cyclones in Philippine history, killing at least 5,081 people. Forming out of a tropical disturbance on November 1, 1991, several hundred kilometers north-northeast of Palau, the depression that would become Thelma tracked generally westward. After turning southwestward in response to a cold front, the system intensified into a tropical storm on November 4 as it approached the Philippines. Hours before moving over the Visayas, Thelma attained its peak intensity with estimated ten-minute sustained winds of 75 km/h (45 mph) and a barometric pressure of 992 mbar (hPa; 29.29 inHg). Despite moving over land, the system weakened only slightly, emerging over the South China Sea on November 6 while retaining gale-force winds. Thelma ultimately succumbed to wind shear and degraded to a tropical depression. On November 8, the depression made landfall in Southern Vietnam before dissipating hours later.

1985 Atlantic hurricane season The 1985 Atlantic hurricane season had 6 U.S. landfalling hurricanes, which was the highest number in 99 years. The season officially began on June 1 and lasted until November 30. It was an average season, with 11 named storms developing. This was partially attributed to a La Niña – a meteorological phenomenon that produces favorable conditions across the Atlantic basin, such as lower wind shear and higher sea surface temperatures. The first storm, Ana, developed on July 15 near Bermuda and caused minor effects in Canada while transitioning into an extratropical cyclone. Three other tropical cyclones – Claudette, Henri, and Isabel – did not significantly affect land. Claudette developed offshore of the Southeastern United States and brushed Bermuda and the Azores. Henri and Isabel were dissipating as they approached land. However, the precursor of the latter caused a severe flood in Puerto Rico that killed 180 people. Additionally, Tropical Storm Fabian and three tropical depressions did not have any known impact on land.

1982–83 South Pacific cyclone season The 1982–83 South Pacific cyclone season was one of the most active and longest South Pacific tropical cyclone seasons on record, with 14 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. During the season tropical cyclones were monitored by the meteorological services of Australia, Fiji, French Polynesia and New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC), also monitored the basin and issued unofficial warnings for American interests. The first tropical cyclone of the season developed a day before the season officially began on October 31, while the last tropical cyclone of the season dissipated on April 23. Most of the activity during the season occurred within the central and eastern parts of the basin with French Polynesia affected by several systems.

2016–17 Australian region cyclone season The 2016–17 Australian region cyclone season was a slightly below-average season in terms of activity, with nine tropical cyclones, three of which intensified further into severe tropical cyclones; though it was much more active than the previous season. The season was the first to have a severe tropical cyclone since the 2014–15 season. It was the period of the year when most tropical cyclones form in the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. The season officially ran from 1 November 2016 to 30 April 2017, however, a tropical cyclone could form at any time between 1 July 2016 and 30 June 2017 and would count towards the season total. The first named storm, Yvette, developed during 21 December, and the final named storm, Greg, left the region on 3 May as a remnant low.

Typhoon Nelson (1982) Typhoon Nelson, known in the Philippines as Typhoon Bising, was the second tropical cyclone to strike the Philippines within a week in March 1982. Nelson originated from a tropical disturbance southeast of Guam towards the middle of March. Although the system was initially poorly organized, it developed rather quickly, and was upgraded into Tropical Storm Nelson on March 19. It tracked westward, and fluctuated in intensity for several days. On March 24, Typhoon Nelson intensified into a typhoon, and entered an episode of rapid intensification. On March 25, Nelson reached its peak intensity of 115 km/h , but thereafter moved ashore on the Philippines, where the storm weakened significantly. On March 27, the typhoon entered the South China Sea, and the next day, briefly re-intensified before resuming a weakening trend. Nelson dissipated on March 31. Affecting the nation less than a week after Tropical Storm Mamie did, Nelson was responsible for additional flooding across much of the Philippines. Fifty-six people were killed due to the typhoon, eight of whom perished due to drownings. Over 1,200 homes were destroyed. More than 165,000 people fled to shelters, including 83,000 that were displaced from their home. Thirty fishing boats and 23 ferries were destroyed due to the system. Damage amounted to $17.2 million (1982 USD).

Cyclone Alby Severe Tropical Cyclone Alby was regarded as the most devastating tropical cyclone to impact southwestern Western Australia on record. Forming out of an area of low pressure on 27 March 1978, Alby steadily developed as it tracked southwestward, parallel to Western Australia. Between 1 and 2 April, the storm quickly intensified and attained its peak intensity as a Category 5 cyclone on the Australian cyclone intensity scale. After turning to the southeast, the storm underwent an extratropical transition as it neared Cape Leeuwin. The storm brushed the cape on 4 April, bringing hurricane-force winds, before rapidly losing its identity the following day.

Hurricane Doreen (1977) Hurricane Doreen was considered the worst tropical cyclone to affect California in 32 years. The tenth tropical cyclone, fourth named storm, and second hurricane of the otherwise inactive 1977 Pacific hurricane season, it developed on August 13. The depression tracked northwestward, intensifying into Tropical Storm Doreen later that day. Further strengthening occurred over the subsequent days, and Doreen attained its peak as a minimal hurricane early on August 15. Executing a turn towards the north-northwest, Doreen made its first landfall as a Category 1 hurricane on the Saffir–Simpson Hurricane Wind Scale near Puerto San Carlos. Drifting offshore, Doreen made a second and final landfall near the northern portion of the Baja California as a tropical storm before rapidly weakening to a tropical depression. The tropical depression dissipated south of southern California on August 18.

1988–89 South-West Indian Ocean cyclone season The 1988–89 South-West Indian Ocean cyclone season was an active season that featured several storms moving near or over the Mascarene Islands or Madagascar. The eleven tropical storms was two greater than average, of which five became tropical cyclones – a storm with maximum sustained winds over 10 minutes of 120 km/h (75 mph) or greater. Storms were monitored by the Météo-France office (MFR) on Réunion island in an official capacity, as well as the American Joint Typhoon Warning Center (JTWC) on an unofficial base. The season began early with Moderate Tropical Storm Adelinina forming in early November, and continued through the middle of April. Adelinina was one of two storms to form in November, the other being Tropical Cyclone Barisaona which crossed from the adjacent Australian basin.

Typhoon Maysak (2015) Typhoon Maysak, known in the Philippines as Typhoon Chedeng, was the most powerful pre-April tropical cyclone on record in the Northwestern Pacific Ocean. The fourth named storm of the 2015 Pacific typhoon season, Maysak originated as a tropical depression on March 26. The next day, the Japan Meteorological Agency (JMA) upgraded the depression to a tropical storm and assigned it the name "Maysak". According to the JMA, Maysak became the second typhoon of the year on March 28. The typhoon explosively intensified into a Category 5 super typhoon on March 31, passing near the islands of Chuuk and Yap in the Federated States of Micronesia. After maintaining that intensity for 18 hours, Maysak weakened, made landfall over the Philippine island of Luzon as a minimal tropical storm, and dissipated shortly afterwards.

Cyclone Ita Severe Tropical Cyclone Ita was the strongest tropical cyclone in the Australian region by pressure since George in 2007, and since Monica in 2006 by wind speed. The system was first identified over the Solomon Islands as a tropical low on 1 April 2014, and gradually moved westward, eventually reaching cyclone intensity on 5 April. On 10 April, Ita intensified rapidly into a powerful Category 5 system on the Australian Scale, but it weakened to a Category 4 system in the hours immediately preceding landfall the following day. At the time of landfall at Cape Flattery at 12 April 22:00 (UTC+10), the cyclone's Dvorak intensity was approximately T5.0, consistent with a weak Category 4 system, and considerably lower than T6.5 observed when the system was at its peak intensity. Meteorologists noted the system had, at that time, begun an eyewall replacement cycle; as a result, the system was considerably less powerful than various intensity scales predicted. Ita's impact on terrain was attenuated accordingly.

Hurricane Amanda Hurricane Amanda was the strongest Eastern Pacific tropical cyclone ever recorded in the month of May. The first named storm, hurricane and major hurricane of the 2014 Pacific hurricane season, Amanda originated from a tropical wave that had entered the Eastern Pacific on May 16. Slow development occurred as it tracked westward, and development into a tropical depression occurred on May 22. The depression later strengthened into a tropical storm on May 23. Amid very favorable conditions, Amanda then rapidly intensified late on May 23, eventually reaching its peak intensity on May 25 as a high-end Category 4 hurricane. Afterwards, steady weakening occurred due to upwelling beneath the storm, and Amanda fell below major hurricane intensity on May 26. Rapid weakening occurred and the cyclone eventually dissipated on May 29.

Cyclone Hyacinthe Tropical Cyclone Hyacinthe was the wettest tropical cyclone on record worldwide. The eighth named storm of the season, Hyacinthe formed on January 15, 1980, to the northeast of Mauritius in the southern Indian Ocean. Initially it moved to the west-southwest, and while slowly intensifying it passed north of the French overseas department of Réunion. On January 19, Météo-France estimated that the storm had intensified to a tropical cyclone. Hyacinthe looped to the south of eastern Madagascar and weakened, although it restrengthened after turning to the east. The storm executed another loop to the southwest of Réunion, passing near the island for a second and later third time. Hyacinthe became extratropical on January 29 after turning southward, dissipating two days later.

Cyclone Tusi Severe Tropical Cyclone Tusi was a tropical cyclone which affected the island nations of Tuvalu, Tokelau, Western Samoa, American Samoa, Niue and the Southern Cook Islands during January 1987. The precursor tropical depression to Cyclone Tusi developed on January 13, within a trough of low pressure near the island nation of Tuvalu. Over the next few days the system gradually developed further before it was named Tusi during January 16, after it had become equivalent to a modern-day category 1 tropical cyclone on the Australian tropical cyclone intensity scale. After being named the system gradually intensified as it moved southeastwards along the trough, between the islands of Fakaofo and Swains during January 17. Tusi's eye subsequently passed near or over American Samoa's Manu'a Islands early the next day, as the system peaked in intensity with 10-minute sustained wind speeds of 150 km/h (90 mph). The system subsequently posed a threat to the Southern Cook Islands, however this threat gradually diminished as Tusi moved southwards and approached 25S during January 20.

Tropical Storm Zelda (1991) Severe Tropical Storm Zelda was the last storm of the 1991 Pacific typhoon season. A disturbance formed near the International Date Line, and strengthened into a tropical depression on November 27. The Joint Typhoon Warning Center (JTWC) reported that the depression had reached tropical storm intensity, thus naming it Zelda. The storm quickly strengthened into a Category 1 typhoon on the Saffir–Simpson hurricane wind scale near the Marshall Islands on November 29. It reached peak of 110 km/h , with a barometric pressure of 975 mbar . The tropical storm traveled northwestward, and later northeastward. Zelda soon weakened into a tropical storm, and then a tropical depression. The JTWC discontinued warnings on December 4, while the Japanese Meteorological Agency (JMA) continued to track the storm until it crossed the International Date Line again on December 7.

Cyclone Kina Severe Tropical Cyclone Kina was a significant tropical cyclone which became the second-costliest storm to ever hit Fiji, only after Cyclone Winston of 2016. Total losses from Kina are estimated to be near $F ( $US ). The system was first noted as a tropical depression, to the east of the Solomon Islands on December 23. Over the next few days the system moved south-eastwards and gradually developed further, before it was named Kina, after it had developed into a tropical cyclone during December 26.

Cyclone Trina Tropical Cyclone Trina (Fiji Meteorological Service designation: 01F, Joint Typhoon Warning Center designation: 06P) was a weak but destructive tropical cyclone in late 2001 which caused some of the worst flooding in the South Pacific island of Mangaia, Cook Islands, in nearly 50 years. Forming out of an upper-level low pressure system on November 29 near the island of Rarotonga, or roughly 1,470 mi (2,365 km) southeast of Fiji, Trina remained practically stationary as it meandered in the same general area for over a week. Due to unfavorable conditions for tropical cyclogenesis, the storm struggled to develop significant convection, preventing it from intensifying beyond 65 km/h (40 mph). After finally succumbing to wind shear on December 2, the system weakened to a tropical depression near Mangaia and dissipated several days later.
