The 2012 Pacific typhoon season was a slightly above average season that produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season, primarily due to Typhoon Bopha which killed 1,901 people in the Philippines. 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 2012, though most tropical cyclones typically develop between May and October. The season's first named storm, Pakhar, developed on March 28, while the season's last named storm, Wukong, dissipated on December 29. The season's first typhoon, Guchol, reached typhoon status on June 15, and became the first super typhoon of the year on June 17.
The 2015 Pacific typhoon season was a slightly above average season that produced twenty-seven tropical storms, eighteen typhoons, and nine super typhoons. The season ran throughout 2015, though most tropical cyclones typically develop between May and November. The season's first named storm, Mekkhala, developed on January 15, while the season's last named storm, Melor, dissipated on December 17. The season saw at least one named tropical system forming in each of every month, the first time since 1965. Similar to the previous season, this season saw a high number of super typhoons. Accumulated cyclone energy (ACE) during 2015 was extremely high, the third highest since 1970, and the 2015 ACE has been attributed in part to anthropogenic warming, and also the 2014-16 El Niño event, that led to similarly high ACE values in the East Pacific.
The 2016 Pacific typhoon season is considered to have been the fourth-latest start for a Pacific typhoon season since reliable records began. It was an average season, with a total of 26 named storms, 13 typhoons, and six super typhoons. The season ran throughout 2016, though typically most tropical cyclones develop between May and October. The season's first named storm, Nepartak, developed on July 3, while the season's last named storm, Nock-ten, dissipated on December 28.
The 2019 Pacific typhoon season was the costliest Pacific typhoon season on record, just ahead of the previous year and 2023. The season featured fairly above-average tropical cyclone activity for the second consecutive year, producing 29 named storms, 17 typhoons, and five super typhoons. The season's first named storm, Pabuk, reached tropical storm status on January 1, becoming the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record that was held by Typhoon Alice in 1979. The season's first typhoon, Wutip, reached typhoon status on February 20. Wutip further intensified into a super typhoon on February 23, becoming the strongest February typhoon on record, and the strongest tropical cyclone recorded in February in the Northern Hemisphere. The season's last named storm, Phanfone, dissipated on December 29 after it made landfall in the Philippines.
The 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.
Severe Tropical Storm Rumbia, known in the Philippines as Tropical Storm Gorio, was a tropical cyclone that brought widespread flooding in areas of the Philippines and China late June and early July 2013. The sixth internationally named storm of the season, Rumbia formed from a broad area of low pressure situated in the southern Philippine Sea on June 27. Steadily organizing, the initial tropical depression moved towards the northwest as the result of a nearby subtropical ridge. On June 28, the disturbance strengthened to tropical storm strength, and subsequently made its first landfall on Eastern Samar in the Philippines early the following day. Rumbia spent roughly a day moving across the archipelago before emerging into the South China Sea. Over open waters, Rumbia resumed strengthening, and reached its peak intensity with winds of 95 km/h (50 mph) on July 1, ranking it as a severe tropical storm. The tropical cyclone weakened slightly before moving ashore the Leizhou Peninsula late that day. Due to land interaction, Rumbia quickly weakened into a low pressure area on July 2 and eventually dissipated soon afterwards.
This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.
Typhoon Dujuan, known in the Philippines as Super Typhoon Jenny, was the second most intense tropical cyclone of the Northwest Pacific Ocean in 2015 in terms of ten-minute maximum sustained winds, tied with Noul. The twenty-first named storm and the thirteenth typhoon of the 2015 Pacific typhoon season, Dujuan brought extremely powerful winds throughout the Yaeyama Islands and Taiwan in late September, causing 3 deaths in Taiwan. The typhoon also caused over ¥2.5 billion (US$392.9 million) damage in East China.
Typhoon Chaba, known in the Philippines as Super Typhoon Igme, was the fourth most intense tropical cyclone in 2016 and the strongest tropical cyclone to make landfall in South Korea since Sanba in 2012. Chaba also caused 7 deaths in the country. Typhoon Chaba was the eighteenth named storm and the eighth typhoon of the 2016 Pacific typhoon season. Chaba originated as a depression around the east-northeast of Guam. Being in a marginally favorable environment, JMA proceeds to name the system as Chaba. On September 28, JTWC gave its identifier as Tropical Depression 21W. Its LLCC starts to improve, prompting the JTWC to upgrade into a tropical storm. Chaba entered the Philippine Area of Responsibility, receiving the name Igme as it moved northwestwards. Chaba became more symmetrical which later ensued its rapid intensification.
Typhoon Nesat, known in the Philippines as Typhoon Gorio, was a strong tropical cyclone that impacted Taiwan and Fujian, China. It was the ninth named storm and the second typhoon of the annual typhoon season. After consolidating slowly for several days, Tropical Storm Nesat developed east of the Philippines on July 25. While experiencing favorable environmental conditions such as very warm sea surface temperatures and low wind shear, Nesat strengthened into a typhoon and reached its peak intensity on July 28. On July 29, the typhoon made landfall near the Taiwanese city of Yilan, before weakening to a severe tropical storm and making landfall again near Fuqing on China's east coast late the same day. Moving into July 30, Nesat continued to weaken under the effects of land interaction.
Typhoon Hato, known in the Philippines as Severe Tropical Storm Isang, was a strong tropical cyclone that struck South China in August 2017. The thirteenth named storm and the fourth typhoon of the Pacific typhoon season, Hato formed as a tropical depression over the east of Luzon on 19 August. The system further developed and became a tropical storm the next day. On 21 August, Hato emerged over the northern portion of the South China Sea and reached typhoon intensity. Rapid intensification ensued on 23 August, and Hato became a Category 3-equivalent typhoon before making landfall over Jinwan, Zhuhai. The storm further weakened over land and dissipated on 24 August.
The 2021 Pacific typhoon season was the second consecutive to have below average tropical cyclone activity, with twenty-two named storms, and was the least active since 2011. Nine became typhoons, and five of those intensified into super typhoons. This low activity was caused by a strong La Niña that had persisted from the previous year. The season's first named storm, Dujuan, developed on February 16, while the last named storm, Rai, dissipated on December 21. The season's first typhoon, Surigae, reached typhoon status on April 16. It became the first super typhoon of the year on the next day, also becoming the strongest tropical cyclone in 2021. Surigae was also the most powerful tropical cyclone on record in the Northern Hemisphere for the month of April. Typhoons In-fa and Rai are responsible for more than half of the total damage this season, adding up to a combined total of $2.02 billion.
The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
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 Wutip, known in the Philippines as Tropical Depression Betty, was the most powerful February typhoon on record, surpassing Typhoon Higos of 2015. The third tropical cyclone, second tropical storm, and the first typhoon of the 2019 Pacific typhoon season, Wutip originated from a low-pressure area on February 16, 2019, that generally tracked westward, passing just south of the Federated States of Micronesia (FSM), before organizing into a tropical depression on February 18. The depression was later classified a tropical storm a day later, attaining the name Wutip from the Japan Meteorological Agency. The storm gradually intensified as it turned northwest, before it underwent rapid intensification on February 23, while passing to the southwest of Guam, and reached its first peak intensity. With winds of 270 km/h (165 mph) estimated by the Joint Typhoon Warning Center, Wutip became the first Category 5-equivalent super typhoon on record in the month of February. Wutip underwent an eyewall replacement cycle shortly afterward and weakened. The storm finished its cycle on February 24, rapidly intensifying once again. Wutip reached a secondary peak intensity the following day, again attaining Category 5-equivalent winds. Thereafter, Wutip rapidly weakened for the rest of its lifespan from strong vertical wind shear, before dissipating over the Philippine Sea on March 2.
Typhoon Vongfong, known in the Philippines as Typhoon Ambo, was a strong tropical cyclone that impacted the Philippines in May 2020. Beginning as a tropical depression on May 10 east of Mindanao, Vongfong was the first storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow northward course, strengthening into a tropical storm on May 12 and curving west thereafter. The next day, Vongfong entered a period of rapid intensification, becoming a typhoon and attaining 10-minute maximum sustained winds of 150 km/h (93 mph). The storm made landfall at this intensity near San Policarpo, Eastern Samar, at 04:15 UTC on May 14. The system tracked across Visayas and Luzon, making a total of seven landfalls. Persistent land interaction weakened Vongfong, leading to its degeneration into a tropical depression over the Luzon Strait on May 17.
Typhoon Maysak, known in the Philippines as Typhoon Julian, was a deadly, damaging and powerful tropical cyclone that struck the Ryukyu Islands and the Korean Peninsula in September 2020. The third typhoon of the 2020 Pacific typhoon season, Maysak formed from a tropical disturbance. The disturbance gradually organized, receiving the name Julian from PAGASA as it became a tropical depression. As the depression strengthened, the JMA subsequently named the system Maysak. Maysak rapidly intensified into a strong typhoon before weakening and making landfall in South Korea.
Typhoon Prapiroon, known in the Philippines as Severe Tropical Storm Florita, was a Category 1 typhoon that worsened the floods in Japan and also caused impacts in neighboring South Korea. The storm formed from an area of low pressure near the Philippines and strengthened to a typhoon before entering the Sea of Japan. The seventh named storm and the first typhoon of the annual annual typhoon season. Prapiroon originated from a low-pressure area far off the coast of Northern Luzon on June 28. Tracking westwards, it rapidly upgraded into a tropical storm, receiving the name Prapiroon due to favorable conditions in the Philippine Sea on the next day.
Typhoon Surigae, known in the Philippines as Super Typhoon Bising, was the strongest Northern Hemisphere tropical cyclone to form before the month of May, one of the most intense tropical cyclones on record and the strongest tropical cyclone worldwide in 2021. The second named storm, first typhoon and first super typhoon of the 2021 Pacific typhoon season, Surigae originated from a low-pressure area south of the Micronesian island of Woleai that organized into a tropical depression on April 12. At 18:00 UTC that day, it strengthened to a tropical storm and was named Surigae by the Japan Meteorological Agency (JMA). The formation of an eye and increasing winds prompted the JMA to upgrade the system to a severe tropical storm on April 13. The storm continued to gradually strengthen, and late on April 15, Surigae became a typhoon. Very favorable environmental conditions then allowed Surigae to begin a bout of rapid intensification; Surigae became a super typhoon the next day, and by April 17, the storm reached its peak intensity, with 10-minute sustained winds of 220 km/h (140 mph), 1-minute sustained winds of 315 km/h (196 mph), and a minimum pressure of 895 hPa (26.4 inHg). This made it the strongest pre-May typhoon on record. Afterward, the storm's weakening outflow and an eyewall replacement cycle caused Surigae to gradually weaken as its track shifted north-northwestward in the Philippine Sea. Following the eyewall replacement cycle, Surigae became an annular tropical cyclone on April 19, and restrengthened slightly. On April 22, the storm began to rapidly weaken as it accelerated northwestward into unfavorable environmental conditions, transitioning into a subtropical storm the next day. The subtropical system subsequently underwent extratropical transition, which it completed by April 24. Afterward, Surigae's extratropical remnant accelerated northeastward. On April 27, Surigae's remnant explosively intensified into a bomb cyclone near the Aleutian Islands, attaining hurricane-force winds. Afterward, the system gradually weakened as it turned eastward, slowing down in the process, before crossing the International Date Line on April 30 and fully dissipating on May 2.
Typhoon Jelawat, known in the Philippines as Tropical Storm Caloy, was a powerful typhoon that affected the Caroline Islands in March 2018. The third tropical storm and the first typhoon of the 2018 Pacific typhoon season, Jelawat originated as a tropical disturbance that struck the Federated States of Micronesia before organizing into a tropical depression on March 24. It further intensified into a tropical storm on the following day, according to the Japan Meteorological Agency, receiving the name Jelawat. Drifting northward, the storm remained unorganized while staying east of the Philippines, though environmental conditions became more favorable along its path. On March 29, Jelawat took an unexpected sharp turn east as it intensified into a typhoon. Upon shifting northeast, Jelawat rapidly intensified on March 30 due to low vertical wind shear and substantial outflow, peaking as a Category 4-equivalent super typhoon. Shortly afterward, the storm began to weaken as wind shear sharply increased, falling below typhoon strength on March 31. The storm transitioned into a subtropical cyclone on April 1, before dissipating on that same day.
