Typhoon Bebinca,known in the Philippines as Tropical Storm Ferdie,was a strong tropical cyclone that affected East China,Guam,Philippines and the Ryukyu Islands in early September 2024. Bebinca made landfall in Shanghai,China,becoming the strongest typhoon to hit the city since Typhoon Gloria in 1949. The thirteenth named storm and sixth typhoon of the annual typhoon season,Bebinca formed from atmospheric convection 385 km (239 mi) east-northeast of Kosrae,was upgraded to a tropical storm by the Japan Meteorological Agency (JMA) on September 10,and was named Bebinca,before turning west-northwest due to interaction with an upper vortex;by September 13,as it entered the Philippine Area of Responsibility,the Philippine Atmospheric,Geophysical and Astronomical Services Administration named it Ferdie,and it eventually moved across the Ryukyu Islands,where both the Joint Typhoon Warning Center and the JMA upgraded it to a minimal typhoon. Inland,Bebinca quickly weakened to a severe tropical storm due to land interaction as it moved west-northwest under the steering influence of the subtropical high. The JMA tracked the system until it was last noted on September 18.
Although Typhoon Bebinca did not make landfall in the Philippines,its associated trough and the southwest monsoon brought heavy rains to many regions,damaging or destroying nearly 97 homes and displacing over 36,626 people. The storm caused at least six fatalities,with two people missing and eleven injuries. In China,Bebinca caused two fatalities and one injury,but the country was soon impacted by Tropical Storm Pulasan just days later. Bebinca significantly affected Guam,leading to storm warnings being issued. In Japan,thousands of homes lost power in Amami,and high winds were recorded in Okinawa Prefecture. Overall,Bebinca caused an estimated US$2.49 billion in damage across the Philippines and China.
Typhoon Bebinca emerged from an area of atmospheric convection 385 km (239 mi) east-northeast of Kosrae on September 5. [1] The system, characterized by a disorganized wave in the easterlies, featured intense deep convection over a large area, supported by favorable conditions for tropical cyclogenesis, [2] such as warm sea surface temperatures of 28–29 °C (82–84 °F), moderate vertical wind shear and good poleward outflow. [3] At 02:30 UTC on September 9, the United States Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert, noting that the system had become well-defined with formative banding in the eastern quadrants. [4] A few hours later, both the Japan Meteorological Agency (JMA) and the JTWC followed suit and upgraded the tropical depression, with the latter designating the system as 14W. [5] [6] On September 10, the depression intensified into a tropical storm and was named Bebinca by the JMA, [7] as it consolidated with a central dense overcast (CDO) feature obscuring its circulation center while tracking near Guam, [7] and subsequently turned west-northwestward due to interaction with an upper vortex. [8] Guam radar imagery showed a well-defined surface circulation, with curved convective bands extending southward from the circulation center and wrapping around the northern part of the system into its western periphery. [9]
Around 00:00 UTC on September 11, the JMA upgraded it to a severe tropical storm, citing Dvorak technique—a method of determining a tropical cyclone's intensity based on satellite appearance. [10] On September 13, the JMA reported that the storm had weakened to a tropical storm due to its near-surface circulation being fully exposed and its banding being fragmented along the northern edge, [11] with a broad tail of deep monsoonal flow and a tropical upper tropospheric trough cell to the west continuing to infuse dry air into the storm's mid-level core. [12] By 06:00 PHT (10:00 UTC), Bebinca had entered the Philippine Area of Responsibility (PAR) and was subsequently named Ferdie by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), [13] but just a few hours later, it exited the PAR. [14] Bebinca then shifted northwestward along the northern edge of a deep subtropical high, [15] and the JMA reported that the storm had regained severe tropical storm status. [16] Satellite imagery revealed a compact, circular system with enhanced radial outflow and flaring convection in the northwest quadrant, [17] leading both the JMA and JTWC to upgrade it to a minimal typhoon the next day as it moved across the Ryukyu Islands; [18] [19] meanwhile, Bebinca developed a ragged eye feature and maintained a symmetrical and impressive CDO over the past six hours. [20] The JMA reported that Bebinca reached its peak intensity at 00:00 UTC on September 15 with 10-minute sustained winds of 140 km/h (85 mph) and a central pressure of 965 hPa (28.50 inHg), [21] before eventually peaking at Category 1-equivalent intensity on the Saffir-Simpson scale with 1-minute sustained winds of 140 km/h (85 mph). [20] On September 16, at around 07:30 CST, [22] Bebinca made landfall in Lingang New City, Shanghai, China, [23] becoming the strongest typhoon to hit the area since Typhoon Gloria in 1949, [24] [25] with a microwave eye feature spanning 29 miles (46 km) and convective bands extending south-southwestward as it moved west-northwestward under the steering influence of the subtropical high. [26] Shortly after landfall, the JTWC discontinued warnings on the system. [27] Inland, Bebinca quickly diminished to a severe tropical storm due to land interaction, [28] with the JMA tracking the system until it was last noted on September 18. [29]
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) stated that the southwest monsoon, locally called Habagat, will enhance when the storm enters the Philippine Area of Responsibility (PAR), and continue after the storm exits the PAR. Bebinca is also predicted to bring heavy rains across the northern portion of the Philippines. Thunderstorms were also expected in the rest of Luzon and Metro Manila. [30] PAGASA also predicted that the storm will intensify into a typhoon, bringing flash floods into the country. [31] PAGASA stated that the storm will bring 1.5–3.5 metres (1.6–3.8 yards) high flash floods to Palawan, Western Visayas, Negros Island Region, Central Visayas, Eastern Visayas, Caraga, Northern Mindanao, Zamboanga Peninsula and the Davao Region. Small waterborne vehicles, like Motor bancas, were advised to take precautionary measures because of the storm. [32] The province of Antique evacuated 545 families because of the storm, suspending classes in all levels. The province provided food packs for the evacuees. [33]
The heavy rains brought by the storm-associated trough and southwest monsoon damaged or destroyed nearly 97 homes in the Philippines, displacing over 36,626 people and causing infrastructure damage estimated at ₱200,000 ( US$ 4,060.91). In total, 203,197 people were affected, with at least six fatalities, two missing persons, and eleven injuries reported. Additionally, power outages occurred in 18 cities and municipalities, while 40 roads were blocked and six bridges were rendered impassable. [34] All fatalities were caused by falling trees, including four children aboard a tricycle in Malabang, Lanao del Sur and two in the Zamboanga Peninsula. [35] According to the National Disaster Risk Reduction and Management Council, 1,381 individuals were preemptively evacuated, while classes were suspended in 244 areas, including nine municipalities that also ceased work operations. [34] Bebinca also caused ₱1.09 billion ( US$ 22.13 million) in agricultural damage and affected 24,247 hectares of farmland. [36]
On September 13, Fujian Provincial Flood Control Office required all fishing boats in a certain area on East China Sea to evacuate to immediate offshore area, as the route of Bebinca wasn't easy to predict. [37] By September 14, the Zhejiang provincial government declared increased alertness, dispatched humanitarian employees, [38] and ordered the relocation of anchored boats, construction netting and tourists. [39] On September 15, the China Meteorological Administration issued a red alert for a typhoon, forecasting intense gales and heavy rainfall in eastern China. [40] State media reported that 414,000 people were evacuated across Shanghai and that 56,000 rescue workers were deployed. [41] [42] Shengsi temporarily closed all of its passenger ship service, [43] and multiple trains and flights were cancelled in Zhejiang. [44] Anhui issued a yellow alert for the typhoon. [45] Due to Bebinca, Shanghai Pudong International Airport and Shanghai Hongqiao International Airport cancelled all flights, and Shanghai Disneyland closed on September 16. [46] All highways inside the city were closed, while driving speeds were limited to 40 kilometres per hour. [42] 570 passenger trains were cancelled in Shanghai. [47] Jiangsu closed highways and bridges over the Yangtze River, [48] as well as recalled fishing boats. [49] Suzhou suspended takeaway delivery services, [50] and Wuxi suspended bus operation in the afternoon. [51] Nanjing dispatched emergency rescue personnel across the city in advance. [52] On September 17, Shandong Provincial Department of Water Resources arranged and deployed preventive and response measures as the typhoon was forecasted to bring significant rainfall to southwester part of the province. [53] In Henan Province, Both Xinxiang and Kaifeng decided to suspend classes of middle and primary schools for one day and Zhengzhou launched IV emergency response against flood. [54]
Bebinca became the second storm to hit China within a few weeks, following Typhoon Yagi's landfall on Hainan Island in the southern part of the country. [55] At least 30,000 households lost power. [42] Four homes were damaged, over 10,000 trees were damaged or uprooted, and 53 hectares (132 acres) of farmland were flooded. [56] Two people were killed after they were electrocuted by a fallen power line in Kunshan, while a falling tree injured one person in Chongming Island. [57] Economic losses were estimated to be ¥10 billion (US$1.4 billion). [58] As Bebinca moved inland, it brought extremely heavy rainfall to the border regions of Henan, Anhui, Shandong and Jiangsu, [59] leading to severe waterlogging and flood in several counties. Floodwater didn't recede in Dangshan until September 22. [60] On the same day, citizens in Yongcheng, Shangqiu posted videos online, saying that the city was still soaked in water and that the water level was rising. [61] Local government have been working day and night to rescue the trapped and drain the floodwater, [62] and farmers are attempting to harvest crops to recover losses. [63]
When the storm passed the Pacific Ocean, Guam was affected, leading to a storm warning all across the territory. After the storm passed the territory, the Government of Guam declared Condition of Readiness Three, a small warning which allows people to go to work, not affecting businesses and the territorial government. [64] In Taiwan, as a way of preparation, weather researchers used artificial intelligence to predict the storm path. The program was also used for Typhoon Gaemi, successfully working a week before the hit. [65] The storm was predicted to bring heavy rains to Taiwan, with possible thunderstorms occurring. [66] The storm was forecast to pass through Okinawa. [67] Power outages affected 7,240 households in Amami. [68] High winds were recorded at Kadena Air Base and parts of Okinawa Prefecture. [69]
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 2013 Pacific typhoon season was the most active Pacific typhoon season since 2004, and the deadliest since 1975. It featured Typhoon Haiyan, one of the most powerful storms and one of the strongest landfalling tropical cyclones in history. It was an above-average season with 31 named storms, 13 typhoons, and five super typhoons. The season's first named storm, Sonamu, developed on January 4 while the season's last named storm, Podul, dissipated on November 15. Despite the activity, most of the first seventeen named storms before mid-September were relatively weak, as only two of them reached typhoon intensity. Total damage amounted to at least $26.41 billion (USD), making it at the time the costliest Pacific typhoon season on record; it is currently the fifth costliest, behind the 2018, 2019, 2023, and 2024 seasons.
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 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.
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. Despite that, this season featured Super Typhoon Goni, which made the strongest landfall worldwide in terms of 1-minute wind speed. 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.
This timeline documents all of the events of the 2012 Pacific typhoon season. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. During the season, 34 systems were designated as tropical depressions by either the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. Since the JMA runs the Regional Specialized Meteorological Centre (RSMC) for the Western Pacific, they assigned names to tropical depressions which developed into tropical storms in the basin. PAGASA also assigned local names to systems which are active in their area of responsibility; however, these names are not in common use outside of the Philippines.
Typhoon Meranti, known in the Philippines as Super Typhoon Ferdie, was one of the most intense tropical cyclones on record. Impacting the Batanes in the Philippines, Taiwan, as well as Fujian Province in September 2016, Meranti formed as a tropical depression on September 8 near the island of Guam. Tracking to the west northwest, Meranti gradually intensified until September 11, at which point it began a period of rapid intensification. Continuing to rapidly intensify, it became a super typhoon early on September 12, as it passed through the Luzon Strait, ultimately reaching its peak intensity on September 13 with 1-minute sustained winds of 315 km/h (195 mph). Shortly afterwards, it passed directly over the island of Itbayat. Meranti passed to the south of Taiwan as a super typhoon, and began weakening steadily as a result of land interaction. By September 15, it struck Fujian Province as a Category 2-equivalent typhoon, becoming the strongest typhoon on record to impact the province. Upon moving inland, rapid weakening ensued and Meranti became extratropical the next day, dissipating shortly afterwards after it passed to the south of the Korean Peninsula.
Typhoon Haima, known in the Philippines as Super Typhoon Lawin, was the third most intense tropical cyclone worldwide in 2016. It was the twenty-second named storm and the eleventh typhoon of the annual typhoon season. Impacting the Philippines less than 3 days after Typhoon Sarika, Haima formed out of a tropical disturbance southwest of Chuuk on October 14, it developed into a tropical storm the next day. Steady strengthening occurred over the next day or two as it tracked westward towards the Philippines. After forming an eye shortly after it was upgraded to a typhoon, Haima began to rapidly strengthen and eventually became a super typhoon on October 18. It later attained its peak intensity as a Category 5-equivalent tropical cyclone before weakening slightly. Haima later made landfall in Peñablanca, Cagayan late on October 19 as a Category 4-equivalent storm. Rapid weakening occurred as it interacted with the landmasses until it entered the Southern China Sea as a weak typhoon. It formed a large ragged eye once again and remained steady in intensity until making landfall in China on October 21. It weakened below typhoon intensity and became extratropical on October 22. The cyclone drifted northeastwards and later eastwards before emerging over water again, but eventually dissipated by October 26.
Severe Tropical Storm Pakhar, known in the Philippines as Tropical Storm Jolina, was a strong tropical storm that impacted South China during late August 2017. This storm followed Typhoon Hato which affected the area a few days prior. Pakhar was the fourteenth named storm of the Pacific typhoon season. Pakhar developed from a tropical depression to the east of Luzon during August 24 and intensified into a tropical storm later that day. Pakhar made landfall over in Aurora on August 25. Pakhar gradually intensified and peaked as a severe tropical storm by August 27, making landfall over Taishan, Jiangmen in Southern China.
The 2021 Pacific typhoon season was the second consecutive season 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.
Tropical Storm Rumbia was a rather weak but very destructive tropical cyclone that caused widespread and disastrous flooding in East China in August 2018. The twenty-second officially recognized tropical cyclone of the 2018 Pacific typhoon season, Rumbia developed from an area of low pressure that developed southeast of the Ryukyu Islands on August 13. Favorable environmental conditions supported development of the low into a tropical depression by August 15. At 12:00 UTC that day, the depression strengthened into Tropical Storm Rumbia, which refers to the Sago palm. Initially moving northward, the cyclone turned westward in response to a building ridge to its northeast while slowly strengthening, reaching its peak intensity with maximum 10-minute sustained winds of 85 km/h (50 mph) on August 16. At 20:05 UTC that day, the storm made landfall in Shanghai at peak intensity, maintaining its strength as it moved inland due to ample environmental moisture. However, Rumbia began to weaken as it continued further inland, degenerating into a tropical depression on August 17 shortly before becoming extratropical over central China. The extratropical remnants of Rumbia accelerated northeastward into the Russian Far East, where they dissipated on August 23.
The 2024 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation in the western Pacific Ocean. It is the fifth-latest starting Pacific typhoon season on record, as well as the deadliest since 2013, the most active since 2019, and the fifth-costliest Pacific typhoon season on record, mostly due to Yagi. The season runs throughout 2024, though most tropical cyclones typically develop between May and October. The season's first named storm, Ewiniar, developed on May 25, and eventually intensified into the first typhoon of the season.
Typhoon Chanthu, known in the Philippines as Super Typhoon Kiko, was the second most intense tropical cyclone worldwide in 2021 after Typhoon Surigae in April. It impacted the Cagayan Valley region of the Philippines and became the strongest typhoon to affect the Batanes province since Typhoon Meranti in 2016. The twenty-ninth tropical depression, fourteenth named storm and fourth typhoon of the 2021 Pacific typhoon season, Chanthu originated from a disturbance well east of the Philippine islands on September 5 which organized into a tropical depression later that day. By the next day, the depression had formed into a mature tropical storm which began to explosively intensify by September 7, featuring a pinhole eye on satellite, characteristic of rapidly intensifying storms. Chanthu became a Category 5-equivalent super typhoon by September 8, the highest category on the Saffir–Simpson scale. Subsequent eyewall replacement cycles caused intensity fluctuations, but on September 10, Chanthu peaked with 1-minute sustained winds of 285 km/h (180 mph) just northeast of extreme northeastern Luzon. The typhoon passed very near the Babuyan Islands before passing directly over Ivana, Batanes as a weakening but still powerful Category 5-equivalent super typhoon. Chanthu continued steadily weakening as it passed just east of Taiwan and eventually stalled just east of Shanghai, China. The storm eventually made its second and final landfall near Ikitsuki, Nagasaki in Japan, before crossing the country's mountainous terrain and becoming an extratropical cyclone on September 18. Chanthu then continued eastward and curved southward, before dissipating on September 20. According to Aon Benfield, economic losses totaled US$30 million.
Severe Tropical Storm Kompasu, known in the Philippines as Severe Tropical Storm Maring was a very large and deadly tropical cyclone that affected the Philippines, Taiwan, and southeast China. Part of the 2021 Pacific typhoon season, Kompasu originated from an area of low pressure east of the Philippines on 6 October 2021. The Japan Meteorological Agency (JMA) classified it as a tropical depression that day. A day later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified it as a tropical depression, naming it Maring. The cyclone was initially heavily disorganised, competing with another vortex, Tropical Depression Nando. Eventually, Maring became dominant, and the JMA reclassified it as a tropical storm, naming it Kompasu. Kompasu made landfall in Cagayan, Philippines, on 11 October 2021, and two days later, the storm made landfall in Hainan, China. The cyclone dissipated on 14 October 2021 while located over Vietnam.
Severe Tropical Storm Ma-on, known in the Philippines as Severe Tropical Storm Florita, was a tropical cyclone that impacted the Philippines in August 2022. The ninth named storm of the 2022 Pacific typhoon season, Ma-on originated as a disturbance over in the Pacific Ocean on August 18, and was upgraded to a tropical depression during the next day. The depression strengthened into a tropical storm receiving the name Ma-on, and became a severe tropical storm late on August 23 before making landfall in the Philippines. It would later make landfall in China and Vietnam on August 25. Ma-on weakened back to a tropical depression and due to unfavorable conditions it dissipated on August 26, 2022.
Typhoon Muifa, known in the Philippines as Typhoon Inday, was a powerful tropical cyclone that affected East China, Taiwan, and the Ryukyu Islands in mid-September 2022. It was the twelfth named storm and fourth typhoon of the 2022 Pacific typhoon season, having originated from an invest in the Pacific Ocean.
Tropical Storm Soulik, known in the Philippines as Tropical Depression Gener, was a weak tropical cyclone that impacted both the Philippines and Vietnam. It formed as the fifteenth named storm of the annual typhoon season in September 2024, Soulik originated from a low-pressure area to the east-northeast of Manila, Philippines on September 14, when it was designated as tropical depression Gener due to its formation within the Philippine Area of Responsibility on September 16. The system gradually shifted westward along the southern edge of a mid-level subtropical high, making landfall in Palanan, Isabela, on September 17. As it traveled further into Luzon, it weakened while encountering the rugged terrain of the Cordillera Central. After emerging over the South China Sea on the next day, the system displayed a broad, disorganized low-level circulation. Although two disturbances in the South China Sea were initially expected to merge closer to Vietnam, the Joint Typhoon Warning Center considered merging these disturbances into one system. Early the next day, the depression strengthened into a tropical storm named Soulik by the Japan Meteorological Agency (JMA). Soulik made landfall near Quang Binh and Quảng Trị, Vietnam, at around 2 p.m. local time. It quickly weakened to a tropical depression due to land interaction, and the JMA continued to monitor the system until it dissipated on September 20.
Tropical Storm Pulasan, known in the Philippines as Tropical Storm Helen, was a tropical cyclone that impacted East China, Japan, South Korea and the Philippines in September 2024. Pulasan, which comes from the Malay word "pulas" meaning "twist," was popular in Southeast Asia for its juicy and sweet taste, developed over the Philippine Sea as a tropical depression on September 15 and strengthened into the fourteenth named storm of the annual typhoon season the following day. After gaining organization, the system rapidly developed and reached its peak intensity with winds of 85 km/h and a central pressure of 992 hPa. Pulasan then turned northwestward, eventually moving across Okinawa Island and making landfall in Zhoushan, Zhejiang, followed by a second landfall in Shanghai, just days after Typhoon Bebinca affected the Shanghai area on September 19. As the storm moved overland, it maintained a well-defined circulation center; however, it gradually turned northeastward under the influence of prevailing mid-latitude westerlies. Pulasan reemerged over the East China Sea, just off the coast of China, showcasing a large, near-symmetric area of deep convection to the southeast on September 20. By 06:00 UTC on September 21, Pulasan had transitioned into an extratropical low as it moved east-northeastward and became embedded within the polar front jet to the north, passing over southern South Korea. The extratropical storm entered the Sea of Japan on September 22, crossed the Tōhoku region, and then emerged into the Pacific Ocean while being absorbed by another extratropical cyclone. The extratropical remnants of Pulasan were last noted by the Japan Meteorological Agency on September 24 near the International Dateline; however, the Ocean Prediction Center indicated that these remnants crossed the International Dateline and entered the Central North Pacific Ocean late on September 25. Afterward, the remnants gradually approached the coast of British Columbia, making landfall on September 27 and dissipating after moving inland the same day.
