The 1990 Pacific typhoon season was another active season. It has no official bounds; it ran year-round in 1990, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.[1] 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 1990 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
Season summary
Systems
41 tropical cyclones formed this year in the Western Pacific, of which 31 became tropical storms. 19 storms reached typhoon intensity, of which 4 reached super typhoon strength.
On January 12, both the JMA and the JTWC identified a tropical depression in the northwest Pacific Ocean.[2][3] The depression intensified over the period of a day to become a tropical storm on January 13, when it received the name Koryn from the JTWC. According to them, but not the JMA, Koryn reached typhoon strength on January 15, when it peaked in intensity. The storm then weakened quite rapidly until it became extratropical on January 17, at 0000 UTC.[4]
A tropical disturbance trekked across the Philippines in mid June, upon entering the South China Sea a depression formed. The depression was upgraded to Tropical Storm Nathan on June 16. Tropical Storm Nathan reached peak intensity of 65mph (100km/h) shortly before striking Hainan Island. In the South China Sea the Chinese ship Tien Fu sank killing 4people. In southern China torrential rains caused flooding in Guangdong Province killing 10people, twopeople drowned in Macau due to high waves. Tropical Storm Nathan then continued northwestwards making a final landfall near the Vietnam/China border.[3]
The monsoon trough spawned a tropical depression east of the Philippines on June 15. It tracked to the northwest then westward, slowly organizing into a tropical storm on June 18. Ofelia turned more to the northwest and became a typhoon on June 20. Paralleling the east coast of the Philippines, it reached a peak of 100mph (155km/h) winds before hitting Taiwan on June 23. Ofelia weakened over the country, and brushed eastern China before dissipating on June 25 near Korea. Ofelia caused heavy flooding throughout its track, resulting in at least 64 casualties.
Typhoon Percy, which developed on June 20, reached a peak of 135mph winds while located a short distance east of the northern Philippines. Increasing vertical shear weakened Percy to a 95mph typhoon before crossing extreme northern Luzon on the 27th, an area that felt the effects of Ofelia only days before. It remained a weak typhoon until hitting southeastern China on the 29th before dissipating on the 1st. Percy caused serious damage and flooding in the Carolina Islands and northern Philippines, amounting to 9 deaths.
65mph Tropical Storm Tasha, which developed on July 21 and meandered through the South China Sea, hit southern China on the 30th, 75miles east of Hong Kong. The storm caused torrential flooding in southern China, causing widespread damage and 108 fatalities.
The origins of Winona can be traced back to Severe Tropical Storm Tasha. On August 2, the remnant low of Tasha, as a patch of thunderstorms over northeastern China, was pushed to the east by a weather front from the west. By August 4, Tasha entered the Yellow Sea, before being pushed south by an anticyclone off northeastern Korea, into the East China Sea. Although the same system, Tasha was named Winona, as it started to strengthen into a tropical storm by August 7. It reached peak intensity with an eye-like feature on August 8, before landfalling over Japan the next day. Later, the remnants became extratropical.
Typhoon Yancy killed 12 people in the Philippines after a landslide destroyed a dormitory. In China, severe damage occurred and at least 216 people were killed.[6] 20 people were killed in Taiwan.[7]
On 15:00 UTC on August 13, a weakening Tropical Storm Aka crossed into the basin from the East Pacific, resulting in the Central Pacific Hurricane Center (CPHC) passing its responsibility to the Joint Typhoon Warning Center (JTWC).[8] The next day, the JTWC downgraded Aka into a tropical depression since it had lost convection due to persistent wind shear caused by a nearby TUTT. On 12:00 UTC on August 15, the JTWC issued the last warning on the system,[citation needed] as it passed south of Wake Island.[8]
On August 15, a large area of convection associated with the inflow of developing Typhoon Yancy was cut off, as Yancy was moving too fast to the west for the convection in the east to be absorbed into Yancy. By August 16, the convection developed a mid to low level circulation, and developed into tropical storm by August 18. Zola intensified into a typhoon by the next day, before reaching peak intensity on August 21. By the next day, Zola made landfall over Japan, before dissipating north of Japan. High winds and heavy rains produced by the storm killed three people and injured 22 others in Japan.
Forming on August23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, the system's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 0000UTC August24 and 0600UTC August27 due to the disruptive effects of the surge, and on August30, Abe peaked in intensity as a Category2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone.[9][10]
Typhoon Abe killed 108–195people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan.[9][11][12] Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5billion yuan (RMB, $741.5–743million USD) to be lost in damages.[10][12][13][14] Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890million yen (JPY, US$6million) in damage was caused.[11][15][16]
Tropical Storm Becky, having developed on August 20, hit northern Luzon on the 26th as a strong tropical storm. It strengthened over the South China Sea to an 80mph typhoon, and hit northern Vietnam at that intensity on the 29th. Becky was responsible for killing 32people and causing heavy flooding.
Typhoon Dot formed from a monsoon trough to the southwest of Guam. Dot moved steadily towards the northwest and strengthened into a typhoon. Typhoon Dot reached peak intensity of 85mph before weakening slight before landfall on eastern Taiwan on 7 September. After passing Taiwan Dot regained typhoon intensity in the Formosa Strait before making a final landfall in Fujian Province, China. On northern Luzon Island rains from Typhoon Dot caused floods killing 4people, on Taiwan 3people died.[3]
Severe flooding produced by the storm killed at least 18 people in Vietnam. At least 4,500 homes were destroyed and another 140,000 were inundated.[17]
Typhoon Flo, which developed on September 12, rapidly intensified on the 16th and 17th to a 165mph super typhoon near Okinawa. Vertical shear weakened it as it recurved to the northeast, and Flo hit Honshū, Japan, on the 19th as a 100mph typhoon. It continued rapidly northeastward, became extratropical on the 20th, and dissipated on the 22nd. Widespread flooding and landslides killed 32 and caused millions in damage.
A tropical disturbance consolidated into a tropical depression on the 23rd of September to the east of the Philippines. Tropical Storm Gene was named as the storm moved towards the northwest and strengthened into a typhoon the next day. Typhoon Gene reached peak intensity of 95mph on the 27th shortly before recurving towards the northeast. Gene then skimmed the coasts of Kyūshū, Shikoku and Honshū Islands in Japan before moving out to sea and turning extratropical. Winds on 85mph were recorded on Kyūshū and heavy rains fell across the region, resulting floods and landslides killed 4people.[3]
Typhoon Hattie formed as Typhoon Gene was accelerating towards Japan. Hattie strengthened into a typhoon on 3 October while moving towards the northwest and reached a peak intensity of 105mph the next day. Typhoon Hattie began to recurve while west of the island of Okinawa. Heavy rains from Typhoons Flo, Gene and Hattie broke the drought that plagued the island. As Hattie accelerated towards Japan it was downgraded to a tropical storm before brushing pass Kyūshū and Shikoku before making landfall on Honshū Island. Heavy rains caused a landslide on Shikoku Island killing three people when a landslide hit a bus.[3]
A category 2 typhoon which did not impact land directly. It formed on October 14 and was classified as a Tropical Depression. It became a tropical storm and a typhoon later. Kyle reached a peak intensity of a Category 2 typhoon on September 20. Then, the storm turned eastward instead of affecting Japan. It stated to weaken and was classified as a tropical storm and eventually dissipated on the 22nd. Kyle did not cause any deaths or damages.
Extreme rainfall, peaking near 31.5in (800mm) triggered extensive flooding that left some regions under 6ft (1.8m) of water. At least 16 people were killed by the storm.[19]
Super Typhoon Mike was the deadliest typhoon of the season. It struck the central Philippines in mid-November, where landslides, flooding, and extreme wind damage to caused over 748 casualties and over $1.94billion in damage (1990USD).[20] The name Mike was retired after this season and replaced with Manny.
As Super Typhoon Owen crossed the Marshall Islands and Caroline Islands in mid to late November, it caused extreme damage to the many islands. Some islands lost 95%-99% of the dwellings, as well as 80-90% crops being destroyed. Through all of the damage, Owen only killed 2people.[21]
Super Typhoon Page formed on November 21 as a tropical depression. From there, it tracked slowly westward, making a cyclonic loop. Page continued westward, and strengthened into a Category 5 typhoon. It then accelerated northeastward, making landfall in Japan on November 30 as a Category 1 typhoon. Page dissipated over northeast Japan on December 3.[21]
The final storm of the season, Russ, formed on December 13. The typhoon brought heavy damage to Guam when it passed near the island on December 20. Damage estimates ranged as high as $120million (1990USD),[citation needed] but nobody perished in the storm.
During the season 30 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started on mid-1989.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. Names not retired from this list will be used again in the 1994 season. This is the same list used for the 1986 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.
Retirement
Due to the severity of damage and loss of life caused by Mike, the name was retired and was replaced with Manny and was first used in the 1993 season. PAGASA also retired the name Ruping for similar reasons and was replaced with Ritang for the 1994 season.
Season effects
This table summarizes all the systems that developed within or moved into the North Pacific Ocean, to the west of the International Date Line during 1990. The tables also provide an overview of a systems intensity, duration, land areas affected and any deaths or damages associated with the system.
The 2004 Pacific typhoon season was an extremely active season that featured the second-highest ACE ever recorded in a single season, second only to 1997, which featured 29 named storms, nineteen typhoons, and six super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2004, though most tropical cyclones typically develop between May and October. The season's first named storm and also the first typhoon, Sudal, developed on April 4, later was reached typhoon status two days later, and became the first super typhoon of the year three days later. The season's last named storm, Noru, dissipated on December 22.
The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.
The 1998 Pacific typhoon season was the least active Pacific typhoon season on record, until it was surpassed 12 years later. It would produce 16 tropical storms, 8 strengthening into typhoons. 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 1998 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The 1997 Pacific typhoon season was a record-breaking season featuring eleven tropical cyclones reaching super typhoon intensity, tying the record with 1965 with the most intense tropical cyclones globally, and was the ninth and last consecutive year of above-average tropical cyclone activity that started in 1989. Its extremely high activity produced highest ACE index ever index recorded in a single tropical cyclone season. In addition, this season had ten Saffir-Simpson Category 5-equivalent tropical cyclones, the most ever recorded, even greater than the 2005 Atlantic hurricane season, and 2020 Atlantic hurricane season, for Category 4, which had nearly half of the amount. The 1997–98 El Niño event was a contributing factor to this unusually high activity. Despite this, the season produced an average number of tropical storms, spawning 28 tropical storms.
The 1995 Pacific typhoon season was a slightly below average season in terms of named storms, ending a 6-year stretch of above average activity. It occurred all year round, though most tropical cyclones formed between May and November.
The 1993 Pacific typhoon season was the most active season for the Philippines, seeing a total of 32 storms forming or entering their area of responsibility. Overall, it was an average season, spawning 28 tropical storms, 15 typhoons and three super typhoons. The season had no official bounds; it ran year-round in 1993, 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.
The 1991 Pacific typhoon season was a slightly above-average season with 29 tropical storms, 17 typhoons and five super typhoons forming. It was quite a catastrophic season – Typhoon Yunya impacted the Philippines in mid June while in the same time experiencing a volcanic eruption, Typhoon Mireille severely impacting Japan, which became known for being the costliest typhoon on record until it was surpassed by Typhoon Doksuri in 2023, and Tropical Storm Thelma on November which became one of the deadliest storms to strike the Philippines, killing at least over 5,000 people.
The 1989 Pacific typhoon season was the first of six consecutive years of above-average activity in the Western Pacific. It was an extremely active season spawning 32 tropical storms, 20 typhoons and five super typhoons. It has no official bounds; it ran year-round in 1989, 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. The first storm, Winona, formed on January 15, while the final storm, Jack, dissipated on December 27. This season was also quite a deadly season that were caused by a few notable storms such as Tropical Storm Cecil, which was the worst storm to impact Vietnam in over 50 years, and Typhoon Gay, which directly impacted the Malay Peninsula as the worst typhoon in 35 years. Both of these storms make up around half of the total fatalities of the entire season alone.
The 1985 Pacific typhoon season was a slightly above average season in terms of named storms, though most storms were weak and short-lived. The season had 28 named storms, 15 typhoons and 1 super typhoon. It ran year-round, thus ending the two-season run which began in 1983 that only had tropical cyclones forming between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 57 tropical depressions formed this year, of which only 28 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. This made the season well above average. Additionally, tropical depressions that enter or form in the Philippine area of responsibility were assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. This year, a total of 17 storms were named this way.
The 1979 Pacific typhoon season featured the largest and most intense tropical cyclone recorded globally, Typhoon Tip. The season also used both male and female names as tropical cyclone names for the first time. Additionally, the season was slightly below-average in terms of tropical cyclone activity, with only 24 storms, 12 typhoons, and 4 super typhoons developing. The season had no official bounds; it ran year-round in 1979, 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 1959 Pacific typhoon season was regarded as one of the most devastating years for Pacific typhoons on record, with China, Japan and South Korea sustaining catastrophic losses. It was an event in the annual cycle of tropical cyclone formation. The season had no official bounds, but tropical cyclones in the Western Pacific Ocean normally develop between May and October.
The 1977 Pacific typhoon season was one of the least active Pacific typhoon seasons on record, with only 19 tropical storms forming. It was also the second of three known typhoon seasons during the satellite era to not produce a Category 5-equivalent super typhoon, sandwiched between the 1974 and 2017 seasons. The season's first storm, Severe Tropical Storm Patsy, formed on March 23 and the last, Typhoon Mary, dissipated on January 2, 1978. With Mary spanning two calendar years, it became the fourth typhoon to do so since 1945. Since then, two other typhoons have achieved this feat.
The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, 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 1974 Pacific typhoon season was the first season on record to not feature a Category 5 equivalent super typhoon; a feat later repeated by the 1977 and 2017 seasons. Even so, the season was overly active, with 32 tropical storms and 16 typhoons being developed this year. It has no official bounds; it ran year-round in 1974, 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 1972 Pacific typhoon season was an above average season, producing 31 tropical storms, 24 typhoons and 2 intense typhoons. It has no official bounds; it ran year-round in 1972, 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 1968 Pacific typhoon season has no official bounds; it ran year-round in 1968, 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 1967 Pacific typhoon season was one of the most active Pacific typhoon seasons on record, witnessing the formation of 35 tropical storms during the season. It began on January 1, 1967, though most storms usually form between June and December within the basin. The first storm of the season, Ruby, formed on January 28 west of the Philippines. 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 1967 Pacific hurricane season. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) were given a numerical designation with a "W" suffix, and any storms reaching 1-minute sustained winds of over 40 mph were given a name. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The 1960 Pacific typhoon season had no official bounds; it ran year-round in 1960, 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 1957 Pacific typhoon season has no official bounds; it ran year-round in 1957, 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 1956 Pacific typhoon season has no official bounds; it ran year-round in 1956, 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.
