Typhoon Oliwa Typhoon Oliwa was one of a record eleven super typhoons in the 1997 Pacific typhoon season. It formed in the central Pacific Ocean on September 2 to the southwest of Hawaii, but it became a typhoon in the western Pacific. Oliwa explosively deepened on September 8, increasing its winds from 85 mph to 160 mph in a 24‑hour period. Afterward, it slowly weakened, and after passing east of Okinawa, Oliwa turned northeast and struck Japan with winds of 85 mph (140 km/h). There, it affected 30,000 people and killed 13; thousands of houses were flooded, and some were destroyed. Offshore South Korea, the winds and waves wrecked 28 boats, while one boat went missing with a crew of 10 people. Typhoon Oliwa dissipated on September 19 in northern Pacific Ocean near the International Date Line.

1997 Pacific typhoon season The 1997 Pacific typhoon season has no official bounds; it ran year-round in 1997, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. This was the most active tropical cyclone season ever recorded, with a record ten Category 5 storms forming and with an ACE of 594.11.

1993 Pacific hurricane season The 1993 Pacific hurricane season was a slightly active Pacific hurricane season with seven named storms directly impacting land. The season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and 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 developed on June 11, over a month after the traditional start of the season. The final named storm of the season, Tropical Storm Norma, dissipated on October 14. The Central Pacific Ocean saw very little tropical activity, with only one cyclone, Hurricane Keoni, developing in that particular region. However, many storms out of the season crossed the threshold into the Central Pacific, many as hurricanes, and even major hurricanes.

Typhoon Flo (1990) Typhoon Flo, known in the Philippines as Typhoon Norming, was a powerful Category 5 typhoon that killed over 30 people and caused over $4 billion (1990 USD) in damages when it struck Honshū, Japan in mid-September 1990. The twelfth typhoon and first super typhoon of the 1990 Pacific typhoon season, it formed on September 8, as Tropical Depression 20W. It reached typhoon status on September 15, 1990. It rapidly intensified on the 16th and 17th to a 165 mph super typhoon near Okinawa. Vertical shear weakened it as it recurved to the northeast, and Flo hit Honshū on the 19th as a 155 km/h (100 mph) typhoon. It continued rapidly northeastward, became extratropical on the 20th, and dissipated on the 22nd.

Hurricane Hernan (2002) Hurricane Hernan was the second of three Category 5 hurricanes during the 2002 Pacific hurricane season. The twelfth tropical cyclone, tenth named storm and sixth hurricane of the season, Hernan originated from a tropical wave that formed in the Atlantic Ocean and crossed to the Pacific Ocean. The wave spawned a low pressure system which organized into a tropical depression on August 30, a tropical storm on August 31 and a hurricane later that day. Hernan rapidly intensified and reached peak intensity as a Category 5 storm on the Saffir-Simpson Hurricane Scale. Proceeding northwest, it maintained this strength for eight hours, but on September 2 it entered cooler waters and began to weaken. By September 6 it had degenerated into a remnant area of low pressure.

Typhoon Doug (1994) Super Typhoon Doug, known in the Philippines as Typhoon Ritang, was the only Category 5 typhoon in the 1994 Pacific typhoon season. The 13th storm and the second super typhoon of the season, it formed on the eastern end of a monsoon trough and developed into a tropical depression on August 2. It moved west and rapidly strengthened. Doug reached a peak of 925 mbar and winds of 160 mph before brushing the coast of Taiwan. Doug made landfall near Shanghai, China as a weak tropical depression. Doug killed 26 people and caused $110 million (1994 USD) damage in Taiwan. Dough's effects reached Korea.

Typhoon Ma-on (2011) Typhoon Ma-on, known in the Philippines as Typhoon Ineng, was a large and powerful typhoon that affected southern Japan in July 2011. It was the sixth named storm and second typhoon of the 2011 Pacific typhoon season. Originating from an area of low pressure near Wake Island on July 9, the precursor to Ma-on gradually developed as it moved westward. By July 11, it had become sufficiently organized to be declared a tropical depression, although the cyclone's circulation remained broad. Over the following days, Ma-on gradually intensified and attained typhoon status on July 14. Favorable environmental conditions allowed for additional strengthening, and the storm ultimately attained peak ten-minute sustained winds of 175 km/h (110 mph) on July 16. After turning northward in response to a weakening subtropical ridge, the typhoon underwent a series of eyewall replacement cycles that caused it to weaken. On July 19, Ma-on struck Shikoku before turning southeastward and moving back over water. Slow weakening continued as Ma-on succumbed to the effects of high wind shear. The system ultimately became extratropical on July 24, and was last noted by the Japan Meteorological Agency a week later near the Kamchatka Peninsula.

Typhoon Nangka (2015) Typhoon Nangka was a large and strong tropical cyclone that impacted central Japan in July 2015. Nangka started its long-living journey as a tropical disturbance over the Marshall Islands and west of the International Dateline, becoming the eleventh named storm of the annual typhoon season on July 3. It quickly intensified while moving to the west-northwest, attaining typhoon status on July 6. Nangka moved through the Northern Marianas Islands, passing directly over the uninhabited island of Alamagan. Shortly thereafter, the typhoon attained peak winds; the Japan Meteorological Agency (JMA) estimated 10‑minute sustained winds of 185 km/h (115 mph), while the unofficial Joint Typhoon Warning Center (JTWC) estimated 1‑minute winds of 250 km/h (155 mph), making it a super typhoon. Nangka later weakened as it curved to the north, moving across central Japan on July 16 as a minimal typhoon. The storm weakened soon after, dissipating in the Sea of Japan on July 18.

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.

1875 Atlantic hurricane season 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.

Typhoon Janis (1992) Typhoon Janis, known in the Philippines as Typhoon Gloring, was an early-season typhoon that struck Japan during August 1992. An area of disturbed weather formed near Pohnpei in late-July 1992, and after an increase in thunderstorm activity, and on August 3, a tropical depression developed. After tracking near Guam, Janis tracked generally westward, and on August 5, the storm was believed to have attained typhoon intensity. After intensifying at a brisk pace, Janis attained peak intensity on August 6 near Okinawa. Thereafter, the typhoon began to weaken and accelerate as it recurved towards Kyushu, where it made landfall on the next day. Land interaction took its toll on the typhoon as it tracked northeast, paralleling the western coast of Honshu. On August 9, Janis transitioned into an extratropical low over Hokkaido.

2017 Pacific typhoon season The 2017 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25. This season featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23. This season featured a high amount of activity in the South China Sea, and has been unusually weak, with only one super typhoon forming as of September 26.

Hurricane Iniki Hurricane Iniki ( ; Hawaiian: "ʻ iniki" meaning "strong and piercing wind") was the most powerful hurricane to strike the U.S. state of Hawaii in recorded history. Forming on September 5, 1992, during the strong 1990–95 El Niño, Iniki was one of eleven Central Pacific tropical cyclones during that season. It attained tropical storm status on September 8 and further intensified into a hurricane the next day. After turning north, Iniki struck the island of Kauaʻ i on September 11 at peak intensity; it had winds of 145 mph and reached Category 4 on the Saffir–Simpson hurricane scale. It had recorded wind gusts of 225 as evidenced by an anemometer that was found blown into the forest during clean up. It was the first hurricane to hit the state since Hurricane Iwa in the 1982 season, and the first major hurricane since Hurricane Dot in 1959. Iniki dissipated on September 13 about halfway between Hawaii and Alaska.

Typhoon Kent (1992) Typhoon Kent was a mid-season typhoon that struck southern Japan during August 1992. An area of convection developed east of the International Date Line. Tracking west-northwestward, a tropical depression developed on August 5, and the next day, intensified into a tropical storm. On August 8, increased vertical wind shear caused convection to decrease, although the next day, Ken strengthened into a typhoon. An eye then appeared, and on August 11, Ken attained its peak intensity. Under the influence of a subtropical ridge located to its north, the typhoon initially continued to move west-northwestward before turning turning towards Kyushu. The storm steadily weakened prior to making landfall on August 18 just below typhoon intensity. The mountainous terrain of Japan accelerated the weakening trend, and on August 20, Kent dissipated.

1995 North Indian Ocean cyclone season The 1995 North Indian Ocean cyclone season was below-average and was primarily confined to the autumn months, with the exception of three short-lived deep depressions in May. There were eight depressions in the basin, which is Indian Ocean north of the equator. The basin is subdivided between the Bay of Bengal and the Arabian Sea on the east and west coasts of India, respectively. Storms were tracked by the India Meteorological Department (IMD), which is the basin's Regional Specialized Meteorological Center, as well as the American-based Joint Typhoon Warning Center (JTWC) on an unofficial basis.

Typhoon Betty (1987) Typhoon Betty, known in the Philippines as Typhoon Herming, was a powerful and destructive tropical cyclone that struck the Philippines in August 1987. The seventh typhoon and second super typhoon of the active typhoon season, it formed from the monsoon trough that spawned a tropical cyclone on August 8 while around positioned well to the east of the Philippines. It drifted northwestward, becoming a tropical storm on August 9 and a typhoon on August 10. Betty turned westward, where it rapidly intensified before attaining peak intensity on August 11. The next day, Typhoon Betty made landfall in the central Philippines. Betty weakened rapidly over the country, but restrengthened somewhat over the South China Sea. Land interaction weakened Betty slightly before it hit central Vietnam on August 16. The next day, Betty dissipated.

2014 Pacific typhoon season The 2014 Pacific typhoon season was a slightly below average season, featuring 23 tropical storms, 11 typhoons, and 8 super typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically develop between May and October. The season began with the development of Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi which dissipated on January 1 of the next year.

1987–88 South-West Indian Ocean cyclone season The 1987–88 South-West Indian Ocean cyclone season was a moderately active cyclone season, with nine named storms. Four of the storms attained tropical cyclone status, which is the equivalent of a minimal hurricane with 10 minute sustained winds of at least 120 km/h (75 mph). The seasonal activity was evenly dispersed, officially beginning on December 9 when the Météo-France office (MFR) on Réunion started tracking Tropical Storm Ariny. The storm crossed 90° E from the adjacent Australian basin, one of two storms in the season to do so along with Cyclone Ezenina. There were also two storms tracked unofficially by the Joint Typhoon Warning Center (JTWC) in November.

Typhoon Francisco (2013) Typhoon Francisco, known in the Philippines as Typhoon Urduja, was a powerful typhoon that strengthened to the equivalent of a Category 5 on the Saffir-Simpson scale, according to the Joint Typhoon Warning Center. The 25th named storm and the 10th typhoon of the 2013 Pacific typhoon season, Francisco formed on October 16 east of Guam from a pre-existing area of convection. With favorable conditions, it quickly intensified into a tropical storm before passing south of Guam. After stalling to the southwest of the island, Francisco turned to the northwest into an environment of warm waters and low wind shear, becoming a typhoon. The JTWC upgraded it to super typhoon status on October 18, while the Japan Meteorological Agency (JMA) estimated peak 10‑minute sustained winds of 195 km/h (120 mph). Gradual weakening ensued, and after the typhoon turned to the northeast, Francisco deteriorated into a tropical storm on October 24. Passing southeast of Okinawa and mainland Japan, the storm accelerated and became extratropical on October 26, dissipating later that day.
