Part of the 2014 Pacific typhoon season |
Typhoon Rammasun,known in the Philippines as Typhoon Glenda,was one of the only four Category 5 super typhoons on record in the South China Sea,with the other ones being Pamela in 1954,Rai in 2021 and Yagi in 2024. Rammasun had destructive impacts across the Philippines,South China,and Vietnam in July 2014. Rammasun is a Thai word for thunder god. [1] After Lingling and Kajiki earlier in 2014,Rammasun became the third tropical cyclone,and first typhoon to directly impact the Philippines in 2014. The ninth named storm and the third typhoon of the annual typhoon season,Rammasun formed in the Intertropical Convergence Zone,an area near the equator where the northeast and southeast trade winds come together,and slowly drifted northwest. Having passed through the islands of Micronesia,the system turned west and quickly moved under the influence of a subtropical ridge (STR). Rammasun posed a significant threat to the Philippine island of Luzon,as it was expected to reach typhoon intensity before making landfall there. [2] Though initially forecast to make landfall in Cagayan Valley,the storm followed a more westerly path and was later forecast to make landfall in Rapu-Rapu,Albay in Bicol Region and then pass through Bataan and Zambales before brushing past Metro Manila. [3]
In preparation for the storm,Governor of Guam Eddie Calvo declared the island in Condition of Readiness 3 [4] and later upgraded it to Condition of Readiness 1. On July 11,NASA satellites revealed Rammasun passing directly over Guam. [5] The American National Weather Service stated that an unexpected rise in wind shear kept the system from intensifying much further before reaching Guam. Rammasun only made landfall on Guam as a tropical depression,with winds much weaker than earlier anticipated. [6] However,under the system,the island received a substantial amount of rainfall,making that day the wettest in around 3 months. The United States territory received 25 to 50 mm (0.98 to 1.97 in) of rain. [7] Along with the Philippines,Taiwan also expected impact from Rammasun. Moderate to heavy rainfall was predicted through most of the country. [8] [9] Chinese meteorologists were focusing on second and/or third landfalls in the Chinese Hainan province and northern Vietnam. Residents of Hong Kong were also warned of rainfall and subsequent landslides. [10]
Following the closure of maritime seaports,more than 100 passengers were reportedly stranded at the Port of Batangas,along with 39 rolling cargoes. Meanwhile,at least 841 passengers were stranded in five ports in the Bicol region,namely Matnog,Tabaco,Bulan,Cataingan and Pilar. [11] A total 50 flights were cancelled and over 100 thousand families were evacuated as the typhoon neared landfall. [12] [13] The Philippine Department of Health said that they have prepared all government hospitals to aid the rescue and relief process during and after the typhoon. They claimed that they are much better prepared now,than they were for earlier typhoons. [14] Ahead of the landfall,a city in the province of Albay had declared a state of calamity. [15] At around 17:00 Philippine Standard Time (09:00 UTC),Rammasun's eye passed directly over Rapu-Rapu,Albay while the storm was at its initial peak intensity. [16] Various parts of the National Capital Region reported power outages during the storm. They were reportedly caused by "a temporary system balance at 1:29 a.m. due to a sudden plant outage." [17] Laguna is one of the badly hit by the typhoon [18] At least 6,000 people were stranded at various seaports throughout the country due to the storm. [19]
On July 9, the United States Joint Typhoon Warning Center (JTWC) started to monitor a tropical disturbance, that had developed to the east of the Micronesian State of Chuuk. [20] At this time the system had a broad and ill-defined circulation center which was associated with flaring and disorganized atmospheric convection. [20] Over the next day the system gradually consolidated within an area of favorable conditions, with convection wrapping around the systems obscured low level circulation center. [21] The system was subsequently declared a tropical depression during the next day, by both the Japan Meteorological Agency (JMA) and the JTWC with the latter assigning it the designation 09W. [22] [23]
Early on July 11, the JTWC reported that the system had intensified into a tropical storm, after they had assessed the intensity slightly higher than the Dvorak estimates from various agencies. [24] Later that day as the system approached Guam, the JTWC reported that the system had not intensified into a tropical storm and downgraded it to a tropical depression. [25] This was because of the lack of supporting Dvorak estimates from various agencies and various observations from Guam, that showed the system was a poorly defined low level circulation center with deep convection sheared to the northwest of the center. [25] Early on July 12, the JMA reported that the depression had become a tropical storm and named it Rammasun, as the system passed through the Rota Channel to the north of Guam. [26] [27] Later that day as Rammasun moved westwards under the influence of the subtropical ridge of high pressure, the JTWC reported that it had regained tropical storm status after Dvorak estimates from various agencies supported it and the low level structure of the system had improved. [28]
Rammasun entered the Philippine area of responsibility and was given a local name, Glenda on July 13. [29] The storm maintained intensity while a burst of deep central convection developed and the LLCC became slightly more well defined. [30] Over the next couple of hours, vertical wind shear decreased gradually. Rammasun tracked in a westerly direction along the periphery of the steering subtropical ridge. Outflow improved along the southwestern quadrant [31] and Rammasun became a typhoon. [32] The LLCC consolidated while convective banding became well defined and tightly wrapped. During July 14, both the JTWC and the JMA upgraded Rammassun to a typhoon after Dvorak estimates from various agencies suggested maximum sustained winds of 65 knots (120 km/h; 75 mph). [33] [34]
Shortly before its Philippine landfall, Rammasun developed a 10 nautical miles (19 km; 12 mi) wide eye. The storm had vigorous equatorward and westward outflow. At that time, the storm was peaking at 80 knots (150 km/h; 92 mph) 1-minute sustained winds [35] and 75 knots (139 km/h; 86 mph) 10-minute sustained winds. [36] Though initially expect to maintain that intensity and make landfall before weakening into a tropical storm again due to land interaction, Rammasun further intensified. Some six hours later, the JTWC spotted a 20 nautical miles (37 km; 23 mi) eye, twice as wide as previously reported. The 1-minute sustained winds were set at 100 knots (190 km/h; 120 mph), equivalent to Category 3 of the Saffir-Simpson Hurricane Wind Scale (SSHWS). [37] Rammasun continued to strengthen, despite land interaction. Post landfall, the storm's windspeed continued to rise, as it was located in a very favorable environment. JTWC initially reported winds of 110 knots (205 km/h; 125 mph) 1-minute sustained winds [38] before correcting it to 115 knots (215 km/h; 130 mph) in their best track, making it a Category 4-equivalent typhoon. [39]
By 00:00 UTC on July 16, Rammasun's eye had re-emerged into the South China Sea. The typhoon lost its eye feature due to its interaction with Philippine's rugged terrain. The convective structure had slightly degraded. However, convective banding remained tightly wrapped around the LLCC. [40]
On July 18, Rammasun entered another area of very warm sea-surface temperatures. Consequently, Rammasun rapidly deepened and was upgraded to a Category 4 super typhoon by the JTWC, [41] [42] which was upgraded to Category 5 in post-season reanalysis. Later that day, Rammasun made landfall over Hainan at peak intensity, [43] making it one of only two typhoons to make landfall at Category 5-equivalent intensity in China. [44] During landfall, a station on Qizhou Island recorded a sea level pressure of 899.2 millibars, the lowest sea level pressure recorded in China and one of the lowest recorded sea level pressures in the world. [45] The next day, the storm started to weaken. Later that day, both agencies downgraded Rammasun to a tropical storm as it moved to the province of Guangxi and made its third landfall. [46] [47] The JTWC made its final warning on the system in the night of the same day. Early on July 20, the JMA reported that Rammasun had weakened into a tropical depression before it was last noted later that day over the Chinese Province of Yunnan. [48] [49] [50]
On July 10, as the JTWC initiated advisories on the system, the United States National Weather Service Weather Forecast Office in Tiyan, Guam (NWS Guam) issued a tropical storm watch for Guam, Rota, Tinian, Saipan and surrounding waters out to 75 km (45 mi). [51] Later that day the Governor of Guam Eddie Calvo, declared the island nation to be in Tropical Cyclone Condition of Readiness 3 (TCCOR 3), as the strongest winds over the island were expected to peak between 80–95 km/h (50–60 mph). [52] Both of these warnings meant that destructive tropical storm force winds were possible on the islands during the next 48 hours. [51] After the system was declared a tropical storm, tropical storm warnings were issued for Guam and Rota, while TCCOR 2 was declared for Guam. [53] [54] [55] After TCCOR 2 was declared, all of the non essential agencies of the Guam Government and several business were shut down, including the Judiciary and University. [54] [55] [56] [57] Six elementary schools around the island were used as storm shelters, while woman who had been pregnant for more than 38 weeks and or high risk were asked to report to the Guam Memorial Hospital. [54] A TCCOR 1 was subsequently declared during July 11, as destructive winds were expected to impact the island nation within twelve hours. [57] As a result, all outdoor activity was prohibited until early the next day when the watches and warnings were cancelled after the system was downgraded to a tropical depression. [58] [59] Eddie Calvo subsequently reverted the TCCOR for Guam to the seasonal TCCOR, as no damaging or destructive winds were expected to affect Guam as the depression moved through the Rota Channel. [60] NWS Guam subsequently noted that heavy thunderstorms had developed near the center of the system as it moved through the Rota Channel and that the weather over Guam could have been a lot worse.

Rammasun (known as "Glenda" in the Philippines) was the first typhoon to impact the Philippines in over eight months, the previous being Typhoon Haiyan. Preparations for Rammasun started in the island nation, early on July 14. [70] In the wake of the storm, The National Transmission Corporation of the country said in their statement, "Preparations included ensuring the reliability of communications equipment, availability of hardware materials and supplies necessary for the repair of damages to facilities, as well as the positioning of line crews in strategic areas, to facilitate immediate restoration work." [71] Storm warning signal number 3 was hoisted over Catanduanes, while signal number 2 was raised over areas such as Camarines Norte, Burias Island, Ticao Island, Marinduque, and southern Quezon. [72] Several islands in southern Luzon and eastern western, and central Visayas were put under storm signal number 1. Over 12 million people, in all, were asked to brace for the typhoon. Classes on all levels were reportedly suspended for the next two days. [73] Philippine National Disaster Risk Reduction and Management Council's head Alexander Pama, in an interview, said "We are already warning the public to be on alert for possible effects of the weather disturbance: landslides, flash floods, strong rains and winds." more than 1,300 villages were advised about floods or landslides.[ citation needed ] The Embassy of the United States in Manila cancelled non-immigrant visa applicant interviews scheduled for July 15 and 16. All applicants were asked to reschedule their interviews. [74]
The Philippine Coast Guard asked all shipping vessels to refrain from travelling. Spokesperson Armand Balilo said "Authorities are already on standby to prevent any maritime vessels from sailing as the Philippines braces for Glenda (Ramassun). [75] Department of the Interior and Local Government Director Edgar Tabell said "All DILG offices in Luzon and Eastern Visayas have been activated to prepare for Glenda. Evacuation centers have been prepared and power lines, bridges and roads have also been checked." He also asked all local officials to fully cooperate with them and provide support to the residents. [76] As the typhoon neared the coastline of Philippines, the entire nation was put on red alert. [77] By the early hours of July 15, the government reportedly evacuated eastern coastal areas of the nation. PAGASA said "Storm surges of up to three meters were expected in coastal villages." [78] However, that evening, several other residents fled their homes as the typhoon intensified much more than anticipated. [79] The civil defence chief of Bicol, in an interview said "We are preparing for the worst... it is critical now that we finish the evacuations. About 6,000 residents had already moved to evacuation centres, with authorities aiming to have another 39,000 take shelter before the typhoon hits. [80] Several cities were warned of storm surge ranging from 1.5 metres (4 ft 11 in) to 3 metres (9.8 ft). [81]
Immediately after the landfall, three fishermen were reported missing. They were reported to have gone out fishing a day ago from the Philippine province of Catanduanes, and failed to return. [82] A wall collapse in Quezon City injured two people. [83]
At least 90% of the total residents of Metro Manila lost power, as poles were toppled and lines downed. The National Grid Corporation of the Philippines posted on Twitter, saying "Around 90% of Meralco’s franchise area is experiencing power outage brought about by downed poles, lines and outages of NGCP’s (National Grid Corporation of the Philippines) transmission lines due to Typhoon Glenda." [84] Strong winds from the storm destroyed several homes in the slums. Most of the capital area was also completely shut down. [85] In total, Rammasun killed 106 people and caused a damage up to Php38.6 billion (US$885 million). [86]

Late on July 16, the Hong Kong Observatory issued the Typhoon Standby Signal No. 1, before issuing the Typhoon Signal Number 3 during the next day as local winds strengthened gradually from the east. [87] Gale-force winds were subsequently recorded offshore and on higher ground, before it made its closest point of approach during July 18, as it passed around 390 km (240 mi) to the southwest of Hong Kong. [87] Winds over the region gradually subsided before the signals were cancelled by the HKO early on July 19. [87] Over the region at least 51 trees were blown down while there were several reports of fallen objects including a lamp post on the Tsuen Wan flyover. [87]
On July 17, Rammasun made landfall near Wenchang City on the island province of Hainan. The city's mayor, Liu Chun-mei, told the Xinhua News Agency that many houses had been damaged and more than 700,000 people evacuated. Qionghai also suffered heavy damage. Hainan closed all its airports while kindergartens and other schools were shut. Resorts in Hainan were ordered to close and the high speed train in Guangdong bound for Hainan suspended. The typhoon killed one person on the island [88] and injured 21. Waves reached up to 13 m (43 ft) on the northern and eastern coasts of the island and the Leizhou Peninsula. [89] The local government dispatched 66 officials in 13 locales to supervise preparations for the typhoon. Xinhua reported that 6,000 people on Hainan were evacuated. Bus companies also suspended operations due to heavy rains and high winds. [90]
51,000 homes were destroyed in Hainan. [91] 88 people were killed in China while total economic losses were counted to be CNY 44.33 billion (US$7.14 billion). [92]
Vietnamese authorities ordered an evacuation of people from parts of the northern coast of the country on July 18 in preparation for Rammasun. [93] Typhoon Rammasun affected the nearby provinces of Haiphong, Thái Bình, and Nam Định. The officials of Quảng Ninh Province have evacuated more than 1,300 people to safe shelters. Prime Minister Nguyễn Tấn Dũng ordered authorities to help in evacuation and "require all boats to remain close to the shore". He commanded the army to install its forces in the areas for possible search and rescue operations. [94] Heavy rains caused minor flooding in urban areas of Hai Phong and the capital, Hanoi. It also submerged the streets of Nguyen Khuyen, Minh Khai, Truong Dinh and Hang Chuoi. Duong Anh Dien, a government official, told Tuoi Tre that he ordered the cancellation of "all administrative meetings". Residents near the coast areas were evacuated to the nearest designated evacuation sites. All vessels and boats were banned from leaving port. The National Center for Hydro-Meteorological Forecasting said the eye of the storm was about 210 kilometers east of Hoàng Sa with wind speeds reaching 149 kilometers per hour. The mountainous province of Bắc Kạn, Cao Bằng, Lai Chau, Lạng Sơn and Lào Cai were put on high alert for flash floods and landslides. Over twenty flights by Vietnam Airlines were cancelled or delayed at Noi Bai International Airport. The trade department reserved foods and goods to assure support for at least 250,000 people in case of an emergency. [95] [96] Overall, around 500 homes were damaged. Throughout Vietnam, Rammasun is responsible for 31 deaths had caused damages of US$59 million. [97]
After the system had caused damage to the Philippines, China and Vietnam, the name Rammasun was retired at the Third Joint Session of the ESCAP/WMO Typhoon Committee and WMO/ESCAP Panel on Tropical Cyclones during 2015. [98] In February 2016, Thailand provided replacement names for Rammasun, and a month later, the name Bualoi was chosen to replace it, [99] and was used for the first time in 2019.
The name Glenda was also retired by PAGASA after damages had exceeded 1 billion, while the name Gardo was selected (and taken out from the fourth auxiliary list of typhoon names, only to be replaced by the name Gomer) to replace Glenda for the 2018 season. [100] [101]
The 2008 Pacific typhoon season was a below average season which featured 22 named storms, eleven typhoons, and two super typhoons. The season had no official bounds; it ran year-round in 2008, 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.
Typhoon Sepat, known in the Philippines as Super Typhoon Egay, was the eighth named tropical storm and the strongest tropical cyclone of the 2007 Pacific typhoon season, that affected the Philippines and made landfall in Taiwan and Fujian. Sepat originated on August 11 via a low-circulation center SE of Naha, Okinawa, and was named by the Japan Meteorological Agency as Sepat on August 12 and Egay in the Philippines by PAGASA as it entered the PAR. Sepat underwent an explosive intensification on the night of August 13, reaching peak intensity at Category 5-equivalent super typhoon intensity the following morning. The storm maintained its strength for 2 days, until it underwent an eyewall replacement cycle, just before he storm makes landfall in Taiwan on August 17 as a Category 3-equivalent typhoon. After crossing the Taiwanese strait, Sepat; already weakening into Category 1 status due to unfavorable conditions, made a second landfall in China on August 18, 2007. The storm persisted across Mainland China, as it transitioned into an extratropical cyclone on August 20, and Sepat, now an extratropical low continued through the Chinese mainland until it finally dissipated near Yunnan Province on August 24.
Typhoon Parma, known in the Philippines as Super Typhoon Pepeng, was the second-wettest typhoon to affect the Philippines, and the second typhoon to affect the country within the span of a week during September 2009.
The 2014 Pacific typhoon season was a slightly below average season in terms of named storms, but featured the highest amount of Category 5 typhoons since 1997. This was mainly due to a developing El Niño that favors multiple powerful storms to form in the basin. The season formed twenty-three tropical storms, eleven typhoons, eight super typhoons, and seven Category 5 typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically develop between May and October. The season began with the development of Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi which dissipated on January 1 of the next year.
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.
Severe Tropical Storm Nock-ten, known in the Philippines as Severe Tropical Storm Juaning, was a strong tropical storm which made a total of four landfalls in Southeast Asia, killing more than 100 people and causing damage estimated at US$126 million. It was the eighth named storm and the fourth severe tropical storm of the 2011 Pacific typhoon season.
Typhoon Nesat, known in the Philippines as Typhoon Pedring, was the most powerful tropical cyclone to directly impact China since 2005. It also struck the Philippines during the 2011 Pacific typhoon season, killing 98 people. It is the 17th named storm, the 11th severe tropical storm, the 7th typhoon and overall, the 30th tropical cyclone to be monitored by the Japan Meteorological Agency(JMA) during the year. Nesat came exactly two years after Typhoon Ketsana made landfall in the Philippines as the most devastating typhoon in the 2009 Pacific typhoon season with a damage of US$1.09 billion and 747 fatalities. Nesat was also the first of twin tropical cyclones to batter the Philippines within one week during September 2011, the second was Nalgae.
Typhoon Rammasun, known in the Philippines as Typhoon Florita, was the first of four typhoons to contribute to heavy rainfall and deadly flooding in the Philippines in July 2002. The fifth tropical cyclone of the 2002 Pacific typhoon season, Rammasun developed around the same time as Typhoon Chataan, only further to the west. The storm tracked northwestward toward Taiwan, and on July 2 it attained its peak intensity with winds of 155 km/h (96 mph). Rammasun turned northward, passing east of Taiwan and China. In Taiwan, the outer rainbands dropped rainfall that alleviated drought conditions. In China, the rainfall occurred after previously wet conditions, resulting in additional flooding, although damage was less than expected; there was about $85 million in crop and fishery damage in one province.
Typhoon Bopha, known in the Philippines as Super Typhoon Pablo, was the strongest tropical cyclone on record to ever affect the Philippine island of Mindanao, making landfall as a Category 5 super typhoon with winds of 175 mph (282 km/h). The twenty-fourth tropical storm, along with being the fourth and final super typhoon of the 2012 Pacific typhoon season, Bopha originated unusually close to the equator, becoming the second-most southerly Category 5 super typhoon, reaching a minimum latitude of 7.4°N on December 3, 2012, as only Typhoon Louise of 1964 came closer to the equator at this strength, at 7.3°N. After first making landfall in Palau, where it destroyed houses, disrupted communications and caused power outages, flooding and uprooted trees, Bopha made landfall late on December 3 in Mindanao. The storm caused widespread destruction on Mindanao, leaving thousands of people homeless and killing 1,901 people.
Typhoon Krosa, known in the Philippines as Typhoon Vinta, was a typhoon that made landfall in the northern Philippines in late October 2013. Forming on October 27 near Guam, the storm slowly intensified while moving westward. Krosa developed an eye and became a typhoon before striking Luzon on October 31. The storm weakened over land, but re-intensified over the South China Sea, reaching peak winds of 150 km/h (93 mph) on November 2 off the southeast coast of China. Typhoon Krosa stalled and encountered unfavorable conditions, resulting in quick weakening. By November 3, it had weakened to tropical storm status, and was no longer being warned on by the next day. In northern Luzon, Krosa damaged 32,000 houses, including 3,000 that were destroyed, and caused four fatalities. High winds and rainfall left ₱277 million in damage.
This timeline documents all of the events of the 2014 Pacific typhoon season. Most of the tropical cyclones forming 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. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
Typhoon Kalmaegi, known in the Philippines as Typhoon Luis, was the 22nd depression and the 15th named storm of the 2014 typhoon season. Kalmaegi was the first storm to make landfall over the Philippines since Typhoon Rammasun, two months prior. The storm caused flooding in Southeast Asia during mid-September. Kalmaegi started as a disturbance near Palau that could become a tropical cyclone in the next few days. JTWC would designate it to Tropical Depression 15W. PAGASA also named the system Luis as the 11th named storm inside PAR. Environmental conditions became more conducive for intensification, which allowed 15W to intensify into a tropical storm and attained the name Kalmaegi. On September 13, the storm intensified into a Category-1 typhoon as it moved through open warm waters. Around 17:00 PHT on September 14, the eye of Kalmaegi made landfall in the coastal town of Divilacan, Isabela, bringing gusty winds and heavy rains in the area.
Typhoon Hagupit known in the Philippines as Super Typhoon Ruby, was the second most intense tropical cyclone in 2014. Hagupit particularly impacted the Philippines in early December while gradually weakening, killing 18 people and causing $114 million of damage in the country. Prior to making landfall, Hagupit was considered the worst threat to the Philippines in 2014, but it was significantly smaller than 2013's Typhoon Haiyan.
Typhoon Chan-hom, known in the Philippines as Typhoon Falcon, was a large, powerful and long-lived tropical cyclone that affected most countries in the western Pacific basin. The ninth named storm of the 2015 Pacific typhoon season, Chan-hom developed on June 29 from a westerly wind burst that also spawned Tropical Cyclone Raquel in the southern hemisphere. Chan-hom slowly developed while moving to the northwest, aided by warm waters but disrupted by wind shear. The storm meandered near the Northern Marianas Islands, passing over the island of Rota before beginning a steady northwest track. While near the island, the storm dropped heavy rainfall on neighboring Guam, causing flooding and minor power outages. Chan-hom intensified into a typhoon on July 7, and two days later passed between the Japanese islands of Okinawa and Miyako-jima. There, strong winds left 42,000 people without power, while 27 people were injured. Around that time, the storm caused a surge in the monsoon trough, in conjunction with Tropical Storm Linfa, which caused flooding and killed 16 people in the Philippines.
Typhoon Nock-ten, known in the Philippines as Super Typhoon Nina, was the strongest Christmas Day tropical cyclone worldwide in terms of 1-minute sustained winds. Forming as a tropical depression southeast of Yap and strengthening into the twenty-sixth tropical storm of the annual typhoon season on December 21, 2016, Nock-ten intensified into the thirteenth typhoon of the season on December 23. Soon afterwards, the system underwent explosive intensification and became a Category 5-equivalent super typhoon early on December 25. Nock-ten weakened shortly afterwards before making eight landfalls over the Philippines. The typhoon weakened rapidly due to the landfalls as it entered the South China Sea on December 26, turned southwest, and ultimately dissipated on December 28 due to the winter monsoon.
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 2023 Pacific typhoon season was the fourth consecutive below-average season and became the third-most inactive typhoon season on record in terms of named storms, with just 17 named storms developing, only ahead of 2010 and 1998. Despite the season occurring during an El Niño event, which typically favors activity in the basin, activity was abnormally low. This was primarily due to a consistent period of negative PDO, which typically discourages tropical storm formation in this basin. The season was less active than the 2023 Atlantic hurricane season in terms of named storms, the fourth such season on record, after 2005, 2010 and 2020. The season's number of storms also did not exceed that of the 2023 Pacific hurricane season. Only ten became typhoons, with four strengthening further into super typhoons. However, it was very destructive, primarily due to Typhoon Doksuri which devastated the northern Philippines, Taiwan, and China in July, becoming the costliest typhoon on record as well as the costliest typhoon to hit mainland China, and Typhoon Haikui in September, which devastated China, Taiwan, and Hong Kong. The season was less active in Southeast Asia, with no tropical storm making landfall in mainland Vietnam.
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, and the fourth-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.
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.
