The 1990 Pacific typhoon season 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.
[edit] Storms
31 tropical cyclones formed this year in the Western Pacific, of which 30 became tropical storms. 21 storms reached typhoon intensity, of which 4 reached super typhoon strength.

[edit] Tropical Storm Nathan
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 the 16th of June. Tropical Storm Nathan reached peak intensity of 65 mph shortly before striking Hainan Island. In the South China Sea the Chinese ship Tien Fu sank killing 4 people. In southern China torrential rains caused flooding in Guangdong and Zhanjian Provinces killing 10 people, 2 people drowned in Macau due to high waves. Tropical Storm Nathan then continued northwestwards making a final landfall near the Vietnam/China border.[3]
[edit] Typhoon Ofelia
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 the 18th. Ofelia turned more to the northwest and became a typhoon on the 20th. Paralleling the east coast of the Philippines, it reached a peak of 100 mph winds before hitting Taiwan on the 23rd. Ofelia weakened over the country, and brushed eastern China before dissipating on the 25th near Korea. Ofelia caused heavy flooding throughout its track, resulting in at least 64 casualties.
[edit] Typhoon Percy
Typhoon Percy, which developed on June 20, reached a peak of 135 mph winds while located a short distance east of the northern Philippines. Increasing vertical shear weakened Percy to a 95 mph 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.

[edit] Typhoon Steve
[edit] Tropical Storm Tasha
65 mph Tropical Storm Tasha, which developed on July 22 and meandered through the South China Sea, hit southern China on the 30th, 75 miles east of Hong Kong. The storm caused torrential flooding in southern China, causing widespread damage and 108 fatalities.
[edit] Typhoon Vernon
[edit] Typhoon Winona
[edit] Typhoon Yancy
Typhoon Yancy, which formed on August 9 from the monsoon trough, hit northeastern Taiwan on the 19th. It continued westward to hit eastern China on the 20th, where the monsoon surge resulted in heavy flooding amounting to 216 deaths and $170 million (1990 USD) in damage.
[edit] Typhoon Zola
[edit] Typhoon Abe
137 casualties can be attributed to Typhoon Abe, a typhoon hitting China and bringing heavy rain to Taiwan and the Philippines. It lasted from August 22 through the 2nd, and peaked at 100 mph winds.
[edit] Typhoon Becky
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 80 mph typhoon, and hit northern Vietnam at that intensity on the 29th. Becky was responsible for killing 32 people and causing heavy flooding.
[edit] Tropical Storm Cecil
[edit] Typhoon Dot
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 95 mph before weakening slight before landfall on eastern Taiwan on the 7th of 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 4 people, on Taiwan 3 people died.[4]
[edit] Typhoon Ed
[edit] Super Typhoon Flo
Typhoon Flo, which developed on September 8, 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, Japan on the 19th as a 100 mph 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.
[edit] Typhoon Gene
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 95 mph 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 85 mph were recorded on Kyūshū and heavy rains fell across the region, resulting floods and landslides killed 4 people.[5]
[edit] Typhoon Hattie
Typhoon Hattie formed as Typhoon Gene was accelerating towards Japan. Hattie strengthened into a typhoon on the 3rd of October while moving towards the northwest and reached a peak intensity of 105 mph 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.[6]

[edit] Super Typhoon Mike (Ruping)
- Main article: Typhoon Mike
Super Typhoon Mike was the strongest and deadliest typhoon of the season. It struck the central Philippines in mid-November, where landslides, flooding, and extreme wind damage to caused over 876 casualties and over $1.94 billion in damage (1990 USD).[7] The name Mike was retired after this season.
[edit] Tropical Storm Nell
[edit] Super Typhoon Owen
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 2 people.

[edit] Typhoon Russ
The final storm of the season, which formed on December 13, brought heavy damage to Guam when it crossed near the island on the 20th. Damage estimates are as high as $120 million (1990 USD), but nobody perished in the storm.
[edit] 1990 storm names
Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1990 was named Koryn and the final one was named Russ. The name Mike was retired after this season.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) uses its own naming scheme for tropical cyclones within its area of responsibility. Lists are recycled every four years. This is the same list used for the 1986 season. The name Ruping was retired after this year and was replaced by Ritang.
