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. 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 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 240 km/h (150 mph). 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.
The 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 39 tropical storms forming. It had no official bounds; it ran year-round in 1964, 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.
The 1963 Pacific typhoon season has no official bounds; it ran year-round in 1963, 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 1951 Pacific typhoon season was a generally average season with multiple tropical cyclones striking the Philippines. With the exception of January, each month saw at least one tropical system develop; October was the most active month with four tropical cyclones forming. Overall, there were 31 tropical depressions, of which 25 became tropical storms; of those, there were 16 typhoons.
Typhoon Fran, known in the Philippines as Typhoon Reming, produced tremendous rainfall in Japan including, at the time, a national 24-hour record accumulation of 1,140 mm (44.8 in). Forming as a tropical depression on September 3 to the southeast of Guam, Fran steadily intensified as it moved along a general northwest track. After brushing Guam two days later, the system achieved typhoon status on September 6 after the formation of an eye. A period of explosive intensification ensued thereafter and Fran reached its peak as a Category 4-equivalent typhoon with winds of 240 km/h (150 mph) the following day. Gradual weakening began on September 8 as it neared the Ryukyu Islands, and the system subsequently meandered near the islands for two days before striking Kyushu on September 12. It then moved over the Sea of Japan where it transitioned into an extratropical cyclone and ultimately dissipated on September 16.
Typhoon Nabi, known in the Philippines as Super Typhoon Jolina, was a powerful typhoon that struck southwestern Japan in September 2005. The 14th named storm of the 2005 Pacific typhoon season, Nabi formed on August 29 to the east of the Northern Mariana Islands. It moved westward and passed about 55 km (34 mi) north of Saipan on August 31 as an intensifying typhoon. On the next day, the Joint Typhoon Warning Center upgraded the storm to super typhoon status, with winds equivalent to that of a Category 5 hurricane on the Saffir–Simpson Hurricane Scale. The Japan Meteorological Agency estimated peak ten-minute winds of 175 km/h (109 mph) on September 2. Nabi weakened while curving to the north, striking the Japanese island of Kyushu on September 6. After brushing South Korea, the storm turned to the northeast, passing over Hokkaido before becoming extratropical on September 8, before dissipating on September 12.
Typhoon Agnes, known in the Philippines as Typhoon Pining, produced among the heaviest rains recorded during the 20th century in South Korea, with 710 mm (28 in) falling over a two-day span. The storm originated as a tropical depression near Guam on August 25, 1981. Moving along a west-northwest to northwest track, the system gradually strengthened as deep convection organized around it. The depression was assigned the name Agnes on August 27 following the development of gale-force winds. Further intensification to typhoon-status occurred by August 29. Agnes attained its peak intensity on August 31 over the East China Sea as a Category 2-equivalent on the Saffir–Simpson hurricane wind scale with winds of 175 km/h (109 mph). Subsequent interaction with a mid-latitude trough induced an extratropical transition as the cyclone slowed and turned north. The system had lost most of its tropical characteristics by September 1, with the majority of convection sheared northeast over South Korea and Japan. Agnes later accelerated northeast and completed its transition on September 3. The remnants continued along this course, impacting northern Japan and the Kamchatka Peninsula before last being noted on September 6 near the International Date Line.
Typhoon Judy of July 1989 was a strong tropical cyclone that caused extensive damage and loss of life in Japan, South Korea and the eastern Soviet Union. Originating from a monsoon trough on July 21, Judy began as a tropical depression west of the Northern Mariana Islands. Tracking west-northwest, the system gradually intensified into a tropical storm and was given the name Judy on July 23. By this time, the storm had turned due north. Two days later, Judy attained typhoon status as it began a gradual turn to the west-northwest. Late on July 25, the storm peaked with winds of 165 km/h (105 mph). Striking Kyushu on July 27, interaction with the island's mountainous terrain caused Judy to quickly weaken as it neared South Korea. The weakened storm struck the country west of Pusan the following day before losing its identity near the border with North Korea. The remnants of Judy were last noted over the Sea of Japan.
Typhoon Charlotte was a damaging typhoon that struck Okinawa during the 1959 Pacific typhoon season. An area of low pressure developed in early October, and it became a tropical depression on October 9. The depression strengthened to a tropical storm one day later, and it received the name Charlotte from the Joint Typhoon Warning Center (JTWC). The system strengthened quickly and became a typhoon eighteen hours later. Charlotte continued to rapidly strengthen to its peak of 260 km/h (160 mph) on October 13. The typhoon began to weaken afterwards, and it traveled south of Okinawa on October 16. The typhoon weakened to a tropical storm on October 19 as it began its extratropical transition. The storm became extratropical later that day, and the Japan Meteorological Agency (JMA) ceased tracking the system on October 20.
Typhoon Dinah, known as Typhoon Luding in the Philippines, was the costliest tropical cyclone to form in the 1987 Pacific typhoon season. It also was the fourth typhoon to form during August 1987. An area of low pressure developed near Guam on August 19, and two days later, the low reached tropical storm intensity as it moved generally west. Intensification was initially gradual, with Dinah becoming a typhoon early on August 24, before it subsequently intensified at a faster pace. Dinah reached its highest strength on August 26 before turning northward on August 28 and into a less favorable conditions aloft, which prompted weakening. Dinah entered the Sea of Japan after passing near Okinawa on August 29, where Dinah leveled off in intensity. The system then began to recurve towards southwestern Japan, and after tracking through the area, Dinah transitioned into an extratropical cyclone on August 31, although the remnants could be traced for four more days as it approached the International Date Line.
Typhoon Robyn, known in the Philippines as Typhoon Openg, was a mid-season tropical cyclone that brushed Japan during August 1993. Typhoon Robyn originated from a near equatorial monsoon trough in the eastern Caroline Islands in late July. Tracking west-northwest, a tropical depression developed on August 1, and became a tropical storm the next day. Following an increase in organization, Robyn obtained typhoon intensity on August 5. The typhoon briefly tracked west before veering to the northwest while intensifying. On August 7, Robyn attained its peak intensity of 160 km/h (99 mph), with a barometric pressure of 940 mbar (28 inHg). After passing through the Ryukyu Islands, Robyn skirted past western Kyushu on August 9 while steadily weakening. Midday on August 10, Robyn lost typhoon intensity over the Sea of Japan. The next day, the system was declared an extratropical cyclone.
Typhoon Emma was a strong typhoon that struck Okinawa during the 1959 Pacific typhoon season. An area of severe weather formed near Kwajalein Atoll on October 30, and the Japan Meteorological Agency (JMA) began tracking it as a tropical depression on November 1. The Joint Typhoon Warning Center followed suit on November 5 after finding a closed circulation, and the depression received the name Emma. The depression strengthened into a tropical storm west of Guam on November 6 and gradually gained strength. Emma became a typhoon on November 11 near Luzon, and it reached its peak sustained winds of 205 km/h; 125 mph (110 kn) later that day. The typhoon turned northeastwards and grazed Okinawa the next day. Emma steadily weakened and became extratropical on November 13, and the JMA ceased tracking the storm on November 15.
Typhoon Alice was a typhoon that brought severe flooding to Guam during the latter part of the 1953 Pacific typhoon season. The system was first tracked near the Marshall Islands on October 11 by the Fleet Weather Central (FWC) as a tropical storm, and the Central Meteorological Observatory (CMO) as a tropical depression. The CMO upgraded Alice to a tropical storm east of Guam on October 14. One day later, and the FWC reported that the storm had intensified to 65 knots, equivalent to a Category 1 typhoon on the Saffir–Simpson scale. Near Iwo Jima, the typhoon traveled northeastwards, reaching its peak of 100 kn late on October 18. Alice then steadily weakened down to a tropical storm on October 20. The storm became extratropical on October 23 near the International Date Line, and both agencies ceased tracking the cyclone.
Typhoon Holly, known in the Philippines as Typhoon Isang, affected South Korea, Japan, and the Soviet Union during August 1984. Holly originated from the monsoon trough that extended eastward from its original position in mid-August 1984. Over a period of several days, the system slowly became better organized as it tracked westward, although the system did not initially develop a well-defined center. On August 15, a tropical depression was declared, and on the next day, the depression was upgraded into Tropical Storm Holly. Holly slowly gained strength, becoming a typhoon on August 17 as it passed near Okinawa. The typhoon turned northwest and then north as it rounded a subtropical ridge. At noon on August 19, Holly attained its peak intensity of 130 km/h (80 mph). Shortly after its peak, Holly accelerated northeast due to the westerlies in the general direction of the Korean Peninsula. Land interaction with South Korea triggered a weakening trend, and after entering the Sea of Japan, Holly began to transition into an extratropical cyclone. Thunderstorm activity quickly decreased near the center, and by August 21, Holly had completed its extratropical transition.
Typhoon Kong-rey, known in the Philippines as Super Typhoon Queenie, was a large and powerful typhoon that was tied with Typhoon Yutu as the most powerful tropical cyclone worldwide in 2018. The twenty-fifth tropical storm, eleventh typhoon and 6th super typhoon of the 2018 Pacific typhoon season, Kong-rey originated from a tropical disturbance in the open Pacific. For a couple days, it went westward, organizing into a tropical depression on September 27. Then it intensified into a powerful Category 5 super typhoon early on October 2. Kong-rey underwent an eyewall replacement cycle after its peak intensity, causing it to weaken into a Category 3 typhoon under unfavorable conditions. Kong-rey then struck South Korea on October 6 as a tropical storm. Kong-rey transitioned into an extratropical cyclone later that day while impacting Japan.
Typhoon Louise and Tropical Storm Marge, known in the Philippines as Typhoon Ining and Tropical Storm Liling, respectively, were a pair of tropical cyclones that impacted Palau and the Philippines in November 1964. Louise was one of the most destructive typhoons documented in the central Philippines. Tracking data from meteorological agencies disagree whether the systems were a single tropical cyclone or two distinct tropical cyclones that occurred in quick succession, named separately by the Joint Typhoon Warning Center (JTWC) as Louise and Marge.
Typhoon Kathy, known in the Philippines as Typhoon Welpring, was the largest and longest-lived typhoon in 1964. As the fourteenth named storm of the season, it originated from an area of circulation southeast of Japan by August 11. The following day, the system strengthened into a tropical storm, gaining the name Kathy. Kathy reached typhoon strength on August 13, passing south of Tokyo, approaching the Ryukyu Islands. The typhoon's winds peaked at 165 km/h (103 mph) on August 14, before tapering as the storm curved west-southwest. For the next four days, Kathy and nearby Typhoon Marie began a Fujiwhara interaction, causing both storms to rotate around each other, which ended when Marie was pulled into Kathy's circulation. Between August 15 and August 16, Kathy weakened into a tropical storm, before strengthening back to typhoon status. The storm's west-southwest path brought the center across the Ryukyu Islands and near Okinawa on August 16 as Kathy began to execute a loop in its track. Two days later, Kathy's winds were estimated by the JTWC to be around 215 km/h (134 mph). The typhoon's track made a smaller loop on August 20, before heading northwards. On August 23, Kathy made landfall in Japan with winds of 130 km/h (81 mph) and weakened to a tropical storm. It then curved northeast. On August 25, Kathy transitioned into an extratropical cyclone and continued northeast, reaching the Bering Strait on September 1. Due to its lifetime and large size, the Joint Typhoon Warning Center issued warnings for 13+1⁄2 days, and the storm's circulation reached a radius of 1,370 kilometres (850 mi).
