1966 жылғы Тынық мұхиты тайфун маусымы

The 1966 Pacific typhoon season was an active season, with many tropical cyclones having severe impacts in China, Japan, and the Philippines. Overall, there were 49 tropical depressions declared officially or unofficially, of which 30 officially became named storms; of those, 20 reached typhoon status, while 3 further became super typhoons by having winds of at least Throughout the year, storms were responsible for at least 997 fatalities and $377.6 million in damage; however, a complete record of their effects is unavailable. It is widely accepted that wind estimates in the Western North Pacific during the reconnaissance era prior to 1988 are subject to great error. In many cases, intensities were grossly overestimated due to a combination inadequate technology and a lesser understanding of the mechanics behind tropical cyclones as compared to the present day. Additionally, methodologies for obtaining wind estimates have changed over the decades and is not the same today as in 1966. A joint reanalysis of typhoons from 1966 to 1987 was conducted by the Cooperative Institute for Research in the Atmosphere at Colorado State University and the United States Naval Research Laboratory in 2006 to correct some of these errors. Many storms in 1966 received strength reductions as a result of this study; however, the results of the research have not been implemented into the official database. Notably the number of major typhoons, Category 3 equivalent or higher on the Saffir–Simpson hurricane wind scale, was reduced from eight to six, including the removal of a Category 5. The western Pacific basin covers 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 1966 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center (JTWC). The Japan Meteorological Agency (JMA) also monitored systems in the basin; however, it was not recognized as the Regional Specialized Meteorological Center until 1968. 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 (PAGASA), which can result in the same storm having two names; in these cases both storm names are given below, with the PAGASA name in parentheses.

115 mph Typhoon Irma hit the eastern Samar on May 15. It weakened over the island, but re intensified rapidly to a 140 mph typhoon in the Sibuyan Sea before hitting Mindoro on the 17th. After weakening to a tropical storm, Irma turned northward to hit western Luzon as a 95 mph typhoon on the 19th. It accelerated to the northeast, and became extratropical on the 22nd. The extratropical remnant raced northeast before abruptly slowing on May 23 well to the east of Japan. During that time, it temporarily turned north while moving erratically. The system later acquired a general eastward track by May 26 and accelerated once more before dissipating near the International Date Line on May 29. Severe damage took place across the Philippines, with Leyte suffering the brunt of Irma's impact. Preliminary reports indicated that Tacloban incurred $2.5 million in damage. On May 17, the 740 ton vessel Pioneer Cebu sailed directly into the storm over the Visayan Sea off the coast of Malapascua Island after ignoring warnings to remain at port. Carrying 262 people, the ship struck a reef while battling rough seas in the typhoon. Passengers began abandoning the sinking vessel soon thereafter under the captain's orders while message about the ship's sinking was relayed by the radio operator. A large wave then struck the ship on its side, capsizing and submerging it entirely. Of the passengers and crew, 122 went down with the ship, including captain Floro Yap, while 140 managed to escape. Only five bodies were recovered in the area while the rest were presumed to be lost with the ship in an area referred to as the "graveyard of ships." A trading vessel, the Banca Alex, also sank off the coast of Cebu with 80 people aboard; 60 were later rescued while 20 others were never found.

Southern Taiwan bore the brunt of Judy's impact, with gusts in the region reaching Rainfall on the island peaked at A total of 18 people died while 14 were injured across the island. More than 1,000 homes sustained damage, of which 363 homes were destroyed. The banana crop suffered extensive damage in southern Taiwan, with two provinces reporting 70 percent lost. Total losses to the crop reached $25 million. Total damage amounted to NT$373.5 million.

The incipient disturbance that became Super Typhoon Kit was first identified on June 20 near Chuuk State in the Federated States of Micronesia. The JMA designated that system as a tropical depression that day as the system moved steadily westward. The JTWC followed suit with this classification on June 22 following an investigation by reconnaissance. Early the next day, the depression acquired gale force winds and was dubbed Tropical Storm Kit. Turning to the northwest, Kit developed a wide eye and reached typhoon status late on June 23. During this time, Kit's eye contracted to Around this time, the JTWC estimated Kit to have attained peak winds of ; however, these winds are likely an overestimate. However, the JMA states that the system turned eastward and accelerated over the north Pacific before losing its identity on July 3 near the International Date Line. More than 128,000 homes were affected by flooding, of which 433 collapsed. "Hip deep" waters also shut down Tokyo's subway system, stranding an estimated 2 million people. Throughout the country, 64 people died while a further 19 were listed missing. In the aftermath of the typhoon, 25 workers died from carbon monoxide poisoning from a portable generator while repairing a damaged irrigation tunnel near Utsunomiya.

A tropical depression formed near the Eastern Visayas on July 8 and tracked west northwest. After crossing Luzon on July 11, the system emerged over the South China Sea and began strengthening. Reaching tropical storm intensity on July 12, Lola tracked northwest toward Hong Kong. The system attained its peak intensity the following day with winds of and a pressure of before rapidly dissipating over Guangzhou on July 14.

On August 7, the vessel Almería Lykes sailed into Rita and reported peak sustained winds of and a minimum pressure of Despite this observation, Rita is still considered a tropical storm with winds at that time.

Typhoon Tess produced tremendous rainfall across Taiwan, with Alishan receiving of rain, including in just 18 hours. In contrast to the magnitude of the rain, damage was fairly limited and only one person was killed. Total losses reached NT$11.9 million with 19 homes destroyed and 9 others damaged.

According to the JTWC, Susan was absorbed by the nearby Typhoon Tess on August 16 while east of Taiwan. However, the JMA indicates that the system continued northward as a tropical depression and ultimately dissipated near Kyushu on August 18. As such, the operationally analyzed Tropical Depression Thirteen, which supposedly formed over the East China Sea on August 17, was actually a continuation of Susan.

Owing to the weakening before landfall, Viola caused only minor damage in Japan. Offshore, three vessels capsized amid rough seas.

On October 6, a tropical depression was identified near Kwajalein Atoll in the Marshall Islands. Tracking generally north northeast, little development occurred over the following several days. On October 9, the system was classified as Tropical Storm Kathy. Its motion subsequently stalled and the system executed a small clockwise loop over the following three days. Kathy quickly intensified into a typhoon late on October 9, marked by the formation of a wide eye. The system reached an initial peak with winds of on October 10 before weakening slightly. Turning northeast on October 13, Kathy began reintensifying and achieved its peak strength the following day with winds of and a pressure of 947 mbar (hPa; ).

On November 17, the JMA began monitoring a tropical depression near Yap. Traveling west northwest, the system steadily organized and reached tropical storm strength on November 19. The intensifying storm moved over the Bicol Region of the Philippines that day before striking Calabarzon at its peak with winds of 110 km/h (70 km/h). While passing north of Manila, the cyclone slowed and turned to the southwest before emerging over the South China Sea on November 21. One ship observed winds of that day to the north of Nancy's center. Moving generally west, Nancy gradually decayed over the following five days, degrading to a tropical depression on November 25 and dissipating the following day well to the east of South Vietnam. Tracking northwestward along a similar path to Nancy, the system reached tropical storm strength on November 23 about 350 mile (563 km) east of Manila. The following day, Olga brushed the northern tip of Luzon with peak winds of before turning west and moving over the South China Sea. Subsequent interaction with a monsoon trough caused Olga to weaken and ultimately dissipate on November 25. Images from TIROS aided in locating the system on Christmas Day as it tracked west northwest toward the Philippines. It was estimated to have become a tropical storm that day while located 220 mile (354 km) east of Samar. Pamela rapidly developed soon thereafter, with the first reconnaissance mission early on December 26 reporting it to have achieved typhoon status with a pressure of A wide eye had formed by this time. The typhoon struck northern Samar shortly after 06:00 UTC with winds of Pamela was responsible for heavy damage across the central Philippines with 30 people losing their lives, Initial assessments were difficult due to communication loss with the four hardest hit provinces. Damage was estimated at 15 million PHP (US$6 million). Interaction with land imparted weakening on the system as it moved westward.
