Typhoon Nanmadol,known in the Philippines as Super Typhoon Mina,was the strongest tropical cyclone in 2011 to hit the Philippines and also the second most intense tropical cyclone worldwide in 2011,and the first of the year to directly impact Taiwan and the rest of the Republic of China (ROC). Becoming the eleventh named storm,the seventh severe tropical storm and the fourth typhoon of the 2011 Pacific typhoon season,Nanmadol made a total of three landfalls killing 26,and causing widespread damage worth US$26,464,591. The area of low pressure that was about to become Nanmadol formed on August 19. It drifted north and became a tropical depression on August 21,a tropical storm on August 23 and a typhoon on the same night. Nanmadol reached peak strength with winds of 100 knots (185 km/h;115 mph) (10-minute sustained) and 140 knots (260 km/h;160 mph) (1-minute sustained) threatening the Philippines with heavy rain and flash flooding.
The Filipinos were warned about high waves,strong winds and very heavy rains over the weekend with storm signal 4 raised in parts of the Nation. There,strong winds toppled trees,power and communication lines triggering power outages in the provinces of Cagayan and Isabela. Rivers swelled up on receiving tons on rainwater,overflowing at least six bridges across the two provinces. The typhoon hardly moved in 24 hours bringing relentless rains to the archipelago causing the retaining wall of Baguio's dump facility to collapse. Also,major power lines in the nation were pulled down causing total power failures in Benguet,Cagayan,Apayao,Kalinga and mountain provinces.
Late on August 19, an area of low pressure developed to the north of Palau. [1] Early on August 20, the system became more organized and developed a low-level circulation center. [2] The system then turned north and continued to drift north until on August 21, when the Japan Meteorological Agency (JMA) upgraded the low-pressure area to a tropical depression east of Philippines. [3] The Joint Typhoon Warning Center (JTWC) also issued a Tropical Cyclone Formation Alert (TCFA) on the system reporting that the system was becoming more well organized. [4] Later that day, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started monitoring the system as a tropical depression and named it Mina. [5] Late on August 22, the system became more well organized prompting the JTWC to initiate advisories on the system, designating it 14W. [6]
On August 23, the JMA upgraded 14W to a tropical storm, naming it Nanmadol. [7] Overnight, the system continued to intensify and early on August 24, the JMA upgraded Nanmadol to a severe tropical storm. [8] Later that day, convective banding improved and Nanmadol developed an eye-like feature. [9] As a result, Nanmadol continued to intensify rapidly and became a typhoon, by midnight, that day. [10] The JTWC originally anticipated a fujiwhara effect of Nanmadol on Talas, a weaker tropical cyclone to the east of Nanmadol. [11] However, the two cyclones moved far away from each other with at least a 1,000 nautical miles (1,900 km; 1,200 mi) of distance between them. This prompted the JTWC to change its forecast on the system, from turning east and interacting with Talas, to move west and hit the Philippines. [12] On August 26, Nanmadol reached peak strength with winds of 100 knots (190 km/h; 120 mph) (10-minute sustained) and 140 knots (260 km/h; 160 mph) (1-minute sustained) reaching category 5 status on the SSHS. The typhoon developed a large eye with a diameter of 18 nautical miles (33 km; 21 mi) with highly symmetric deep convective bands wrapped into it. [13]
Nanmadol continued to drift north west and made landfall over Gonzaga, Cagayan, Philippines with strong winds of over 95 knots (176 km/h; 109 mph). [14] After interacting with land, the eye of Nanmadol became cloud filled and the eyewall in the northern semicircle became eroded causing the system to weaken. [15] However, the typhoon maintained tightly curved convective banding and central convection for long time after the landfall. The typhoon maintained a favorable upper level outflow, though located in a mid-level subtropical ridge. [16] As Nanmadol started moving away from Luzon, the eye became more evident and central convection became re-consolidated with curved banding. [17] However, the typhoon did not maintain this for long. Nanmadol could not recover very well from interacting with land and started weakening as the cloud tops were warming up and the eye was being filled with clouds again. [18] During the early hours of August 28, Nanmadol struggled to strengthen after passing over the Babuyan Islands. The eye became completely cloud-filled and the outermost rainbands crossed over Taiwan. [19] This prompted the JMA to downgrade Nanmadol to a severe tropical storm. [20] Later that day, the central convection started depleting as the system approached southern Taiwan. At that time, it was located approximately 245 nautical miles (454 km; 282 mi) south of Taipei in the periphery of a mid-level subtropical ridge. [21] Nanmadol continued to weaken as it approached Taiwan and the winds rapidly decreased to under 75 knots (139 km/h; 86 mph) (1-minute sustained), making Nanmadol a minimal typhoon on the SSHS. It maintained a poorly defined eyewall to its south with convective banding wrapped into the cloud filled center. [22]
Late on August 28, Nanmadol made its second landfall over Dawu Township in Taitung County, Taiwan and started weakening. [23] After a tremendous burst of convection over southern Taiwan, land interaction severely weakened the system. A strong subtropical ridge towards the north-east of the storm started pushing Nanmadol towards the northwest at an increasingly fast pace. [24] Soon, Nanmadol accelerated towards the northwest and entered the Taiwan Strait, with fragmented convective bands wrapped into an adequately defined center. Landfall weakened the system rapidly prompting the JTWC to downgrade Nanmadol to a tropical storm with winds of under 50 knots (93 km/h; 58 mph). [25] Eventually, the JMA too downgraded Nanmadol to a tropical storm with winds of under 45 knots (83 km/h; 52 mph). At that time, it was located to the west of Tainan, Taiwan with 30 knots (56 km/h; 35 mph) winds spreading 220 nautical miles (410 km; 250 mi) towards the north-east and 140 nautical miles (260 km; 160 mi) towards the south-west. [26]
On August 30, Nanmadol slowed moving and became almost stationary. The low level circulation center became exposed and the curved convective banding moved to the south of the system. [27] Soon it started experiencing strong wind shear and continued weakening. The shear pushed convection approximately 70 knots (130 km/h; 81 mph) south of the LLCC. The system also accelerated towards China at 08 knots (15 km/h; 9.2 mph) and weakened to a minimal tropical storm. [28] After its third landfall over Fujian, China, Nanmadol weakened rapidly prompting both the JTWC and the JMA to issue their final warnings on the system. [29] [30]
On August 25, the residents of northern Philippines started preparing for Nanmadol, as the Philippine government advised them about heavy rain and flash flooding after the slow moving typhoon brushes the coasts. [31] On the next day, as the Nanmadol became dangerously strong, storm warning signal 3 was raised over the provinces of Isabela and Cagayan, including the Babuyan Islands. [32] Residents were warned about high waves, strong winds and very heavy rains over the weekend. Also, people living in low-lying areas were instructed to prepare for flash flooding and landslides. [33] The Philippine Department of Health issued a white alert to its subordinates all along Nanmadol's path, ordering them to stock up on medicines and supplies so that the victims need not purchase them at the time of need. [34]
As Nanmadol continued to intensify rapidly, storm signal was upgraded to 4 in some parts of Cagayan. [35] Quickly, the Philippine National Police were fully activated as Nanmadol intensified on nearing the north east Philippine coasts. The PNP were ordered to be in close coordination with the Armed Forces of the Philippines and the Office of Civil Defense. [36] Also, the Philippine Atmospheric, Geophysical and Astronomical Services Administration reported that though Nanmadol was intensifying rapidly, heavy rains were no longer expected. The PAGASA said that unlike Ketsana in 2009, Nanmadol carried less rainwater and would dump less rain when compared to Ketsana. [37] On August 27, several flights were cancelled as the typhoon drifted closer to Philippines unexpectedly. Several sea vessels were also warned about very rough sea conditions over the weekend. [38]
On August 26, the Central Weather Bureau issued a sea warning as they were no longer expecting a Fujiwhara effect, which could possibly pull Nanmadol away from Taiwan. Nanmadol was anticipated to brush Taiwan's eastern coast. [39] All ships passing through the Bashi Channel were warned to stay updated about the typhoon. Also, Taiwanese residents were warned about possible heavy rains and strong winds from Monday, August 29. [40]
On August 27, the Central Emergency Operation Center of Taiwan announced that they were completely prepared for any kind of contingencies triggered by the typhoon. Also, the police in Hualien set up a blockade to prevent people from approaching the seashore where high waves have been detected. [41] Also, the residents of the Pingtung and Taitung counties were asked to prepare for torrential downpour and strong winds. [42] The Opposition Democratic Progressive Party postponed their national congress meeting for the safety of party members and to allow its workers to focus on typhoon relief work. [43]
On August 28, Ma Ying-jeou, the President of the Republic of China ordered evacuations of thousands of people from vulnerable areas, saying that a slow moving typhoon could result in more damages and casualties than normal. [44] The Defense Ministry of Taiwan mobilized some 35,000 soldiers to be ready to help out as many people as possible when the typhoon strikes. The soldiers were in possession of portable power generators, water pumps and amphibious assault vehicles. [45]
On August 29, offices and schools were shut and a yellow alert, the second lowest in the nation's four-level rainstorm alert system was issued by the National Marine Environmental Forecasting Center. [46] Also, the Taiwan Railway Administration halted services on the South-Link Line in fear that heavy rain could trigger landslides and cause rail-accidents. The Directorate General of Highways closed the Suhua Highway saying that the area through which the highway was built is more prone to landslides during typhoons. [47]
After Nanmadol left the island nation of Taiwan and entered the Taiwan Strait, Local authorities started calling back several thousands of ships informing them about the heavy rain the typhoon was pouring. [48] The Maritime affairs bureaus of Fuzhou, Putian, Quanzhou, Xiamen and Zhangzhou cities activated the red warning, the highest level on the Chinese scale, ordering all ships to return to the harbor as soon as possible. [49] The storm was expected to bring heavy torrential rains and flash flooding as is makes landfall on the southern part of Fujian province. [50] For safety insurance, bullet trains along the Wenzhou-Fuzhou and Fuzhou-Xiamen high-speed rail lines were ordered to either operate slowly or suspend services completely if the surveillance system detects any hazards. Also, the shipping route linking Xiamen, in east China's Fujian Province, and Kinmen (Quemoy), in Taiwan was closed at 14:00 local time as the storm entered the strait. [51] The seawalls originally built to resist Nanmadol's strong storm surge were discovered with several cracks, each measuring two meters in length along Jinjiang's coast in the village of Weitou. [52]

On August 23, the system's rainbands caused heavy rains in the Philippines's Zamboanga del Sur province triggering a landslide. No one was reported to be dead or injured however. [53] On August 26, the National Disaster Risk Reduction and Management Council (NDRRMC) reported that one fisherman went missing after local residents reported that they found his banca empty. [54] On that day, the typhoon spawned a tornado in the Biliran Province blowing out three school buildings. No children were reported to be dead or injured although. [55]
On August 27, Nanmadol lashed into the northern tip of the nation bringing heavy rains, causing landslides. Nanmadol, the strongest typhoon to affect the Philippines in 2011, killed two children in a landslide and left two fishermen missing. [56] Later, the NDRRMC started forced evacuations in some areas of the Cagayan province after storm warning signal 4 has been raised. [57] The typhoon's eye passed over the city of Santa Ana with the 24-hour rainfall accumulation over 400 millimetres (16 in). The typhoon also enhanced the Southwest Monsoonal Flow across the Philippines bringing heavy rains and squalls. [58] Another big issue was that the typhoon slowed down after landfall and did not move much in six hours, leaving the northern half of the nation in danger for a longer period of time. [59] Some thirteen families were evacuated from the Isabela province which was earlier hit by the typhoon as the governed ordered dam officials to release water if conditions worsen at the Magat Dam. [60] Nanmadol's strong winds toppled trees, power and communication lines triggering power outages in the provinces of Cagayan and Isabela. Also, the system spawned another tornado which blew out some 18 houses in the Ilocos Norte province. [61] Rivers swelled up on receiving tons on rainwater, overflowing at least six bridges across the two provinces. Another landslide in the Cordillera region blocked zig-zag shaped roads lying between mountains. [62] Late on the day, the NDRRMC reported that by then, Nanmadol killed 6, injured 7 and left 6 more missing. They also added that several towns in Ilocos Norte were completely submerged by floodwater. Several roads in the provinces of Ilocos Sur, La Union and Pangasinan. [63] The typhoon hardly moved in 24 hours bringing relentless rains to the archipelago causing the retaining wall of Baguio's dump facility to collapse. Also, major power lines in the nation were pulled down causing total power failures in Benguet, Cagayan, Apayao, Kalinga and Mountain Provinces. [64]
On August 28, the NDRRMC reported that the typhoon displaced a total of 108,788 people, killing 7, injuring 10 and leaving 6 more missing. A Total of 93 houses were damaged including 16 totally destroyed. A total of 9 bridges and 28 roads remained impassable as floodwater rushed on top of them. Power was restored to many provinces including Isabela communication lines were functional. The only province left without power was Aurora. [65] On August 29, the NDRRMC further upgraded the death toll to 12, the number of injured to 21 and the number of missing to 9. They added that two people from Baguio and Benguet were killed in landslides attributed to Nanmadol. In their report, they also mentioned that the total damage to infrastructure and agriculture caused by Nanmadol was at US$22,475,672. [66] Later the same day, the NDRRMC reported that power was fine restored in Isabela province. Also, the continued to rise the death toll, putting it at 16, and the number of missing at 8. The total damage to agriculture and infrastructure was also upgraded to US$23,748,522. [67]
On August 30, continuing the sequential reports after the typhoon, the NDRRMC pushed up the death toll to 22; the number of injured to 23 and the number of missing to 12. Also, they reported that the total number of houses damaged was 1,316 with 32 totally destroyed. The total damage to agriculture and infrastructure was also increased to US$26,119,801. [68] Later the same day, the NDRRMC further upgraded the death toll to 25; the number of injured to 32 and downgraded the number of missing to 7 reporting that 5 Pangasinan fishermen were rescued. Also, they included that in the wake of Nanmadol, a total of 47 incidents including 14 flashfloods, 12 landslides, 8 tornadoes, 6 sea mishaps, 1 vehicular accident, 4 collapsed structures, 1 lightning strike and 1 soil erosion were monitored. [69] Continuing the daily situational reports, the NDRRMC on September 1, upgraded the death toll to 29, the number of injured to 37 and downgraded the number of missing to 5. They also increased the total damage from Nanmadol to agriculture and infrastructure to US$33,158,317. [70]
On September 2, Benguet and Baguio were declared under State of Calamity by the NDRRMC. Also, the City Health Office Dagupan conducted a survey in their area of responsibility to check if there was any increase in flood-borne diseases. The NDRRMC confirmed more deaths, increasing the toll to 33, and the number of missing to 8 and the total cost of damage to agriculture and infrastructure to US$33,711,271. [71] After thorough reanalysis, the death toll was last raised to 35 and the damage was put at US$34,521,216. [72] Total economic losses in the Philippines were counted to be Php 40.9 billion (US$907.9 million). [73]

As Nanmadol made landfall over Taiwan, it dumped very heavy rainfall over the nation. Some 528 millimetres (20.8 in) of rain was dumped in Hualien County; 517 millimetres (20.4 in) in Hengchun, Pingtung County; 449 millimetres (17.7 in) in Taitung County; 292 millimetres (11.5 in) in Pinglin, New Taipei; 275 millimetres (10.8 in) in Kaohsiung; and 265 millimetres (10.4 in) in Taiping Mountain, Yilan County. [74] The heavy torrential rains soon triggered knee-high flooding across several locations in the nation. Several thousands of people were evacuated as a precaution, when Nanmadol, the first typhoon to directly impact Taiwan since Typhoon Fanapi in 2010 made landfall. [75] The Council of Agriculture soon issued a red-alert for six riverside areas advising people that are at a high risk of mudslides after heavy torrential rains dumped by the typhoon. [76] The early damage estimates to agriculture was reported to be at US$344,790 with bananas hit the hardest sustaining losses of more than NT$3 million. [77] The storm started claiming lives later that day, when debris attributed to the storm hit a motorcyclist killing him almost instantly. [78] Some 30,000 households in southern and eastern Taiwan did not have electricity, 8,000 people were evacuated and several roads and bridges were closed due to the heavy rain. [79]
Even long after Nanmadol left Taiwan, heavy rain continued to batter the nation. Several parts of the nation saw rains of more than on meter and 1.5 meters with Pingtung County was the hardest hit of all. The total economic losses to the nation were put at NT$75.5 million (US$2.6 million). [80] The Hengchun Township was completely inundated by the floodwaters after heavy torrential rain from Nanmadol. The rain was so heavy that a local said, "I never saw so much water in all my 60 years". [81] On August 30, Eqecat reported that the total insured economic losses caused by Nanmadol in Taiwan could exceed US$500 million. [82]
Nanmadol made landfall in China as a weak tropical cyclone bringing heavy rains, prompting local authorities to issue flood and landslide warnings. [83] Also, a female news reporter in China literally escaped death after an unusually large version of the Qiantang River tidal bore (known locally as the "Silver Dragon") amplified by Nanmadol's storm surge rose behind her during a live report. [84] Thousands of fishermen's livelihoods were at risks of being washed away. Evacuations were being carried out with local residents being taken to higher grounds. [85] On August 31, authorities in China reported that the total economic losses caused by Nanmadol in China were more than 44 million yuan (6.9 million U.S. dollars) as the storm destroyed 110 houses having more than 138,000 people evacuated. [86] In Putian City, Nanmadol claimed two lives, leaving four missing after very heavy torrential rains attributed to the storm. Bullet trains were slowed or stopped after the heavy damaged caused by Nanmadol's remnants to Fujian Province. [87] Also, the astronomical high tide coincided with Nanmadol's storm surge bringing unusually high tides which resulted in the increase of the likelihood of coastal flooding. [88]
On September 1, Chinese state owned news agency Xinhua reported that The storm has caused direct economic loss of 130 million yuan or US$20,354,807 with two deaths, twenty injuries and six missing in the Fujian Province. In Zhejiang Province, the torrential rains disrupted the lives of 65,600 people, with 160 houses were toppled and 4,600 hectares of crops destroyed, causing a direct economic loss of 532 million yuan (US$83.13 million). [89]
On August 31, President Ma Ying-jeou visited Pingtung County, the worst hit county to check up on evacuated victims. Unlike Morakot in 2009, Nanmadol was very well forecasted and thousands of lives were saved. [90]
Due to the extremely high amount of damage that the storm has caused in the Philippines, PAGASA announced that the name Mina would be stricken off their tropical cyclone Naming lists. In June 2012, PAGASA chose the name Marilyn to replace Mina for the 2015 Pacific typhoon season.
In contrast, despite the damage in the Philippines and Taiwan, the international name Nanmadol was not retired; it would later be reused in the 2017 and 2022 seasons.
Typhoon Nuri, known in the Philippines as Typhoon Karen, was the 12th named storm and the seventh typhoon that was recognised by the Japan Meteorological Agency. The Joint Typhoon Warning Center recognised it as the 13th tropical depression, the 12th tropical storm and the 8th typhoon of the 2008 Pacific typhoon season. The name Nuri was submitted to the World Meteorological Organisation's Typhoon Committee by Malaysia in 2003 after the name Rusa was retired in 2002. The name Nuri is Malay for a blue crowned parroquet, a type of parrot. The name Karen was assigned by PAGASA to a tropical depression for the second time, the other time being in 2004 to Typhoon Rananim.
Typhoon Sinlaku, known in the Philippines as Typhoon Marce, was a typhoon which affected the Philippines, Taiwan, China and Japan. It was recognised as the 13th named storm and the ninth typhoon of the 2008 Pacific typhoon season by the Japan Meteorological Agency.
Typhoon Mitag, known in the Philippines as Typhoon Mina, was a strong typhoon that caused deadly flooding in the Philippines in November 2007. As the twenty-fourth named storm and the fourteenth typhoon of the 2007 Pacific typhoon season, it originated from an area of atmospheric convection south-southwest of Guam. The area of convection was in a favorable environment for development, so it organized and a low-level circulation was found inside the disturbance. Not too long after, the JMA classified it as a tropical depression. On November 20, rainbands developed along the periphery of the depression as it moved into an area of good divergence. The JMA soon upgraded the depression to a tropical storm, designating it as Mitag. A few hours later, the JTWC issued their first advisory on Mitag, and so did PAGASA, naming it Mina. The storm strengthened significantly early on November 21 and became a further intensified. Later that day, the JTWC upgraded Mitag to a typhoon, and the JMA also upgraded it late that evening. As Mitag remained stationary for a day as a Category 2-equivalent typhoon, it changed its trajectory. Nonetheless, PAGASA announced that there is still a possibility of the typhoon to once again change its course. The storm turned northwest and made landfall late on November 25. It tracked Luzon and was downgraded to a severe tropical storm before emerging back over water on November 26. It turned back to the east before reaching Taiwan, and became extratropical on November 27.
The 2009 Pacific typhoon season was a below average season that spawned only 22 named storms, 13 typhoons, and five super typhoons. Despite this, it was a very deadly season, with the Philippines having experienced its deadliest season in decades due to the impact of typhoons Ketsana and Parma, while typhoon Morakot went on to become the deadliest storm to impact Taiwan in its modern history. The first half of the season was very quiet, whereas the second half of the season was extremely active. The season's first named storm, Kujira, developed on May 3, while the season's last named storm, Nida, dissipated on December 3.
The 2010 Pacific typhoon season, with 14 named storms, was the least active Pacific typhoon season on record. Seven of them strengthened into typhoons while one reached super typhoon intensity. All of the 14 named storms developed west of 150°E.
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 2011 Pacific typhoon season was a below average season that produced a total of 21 named storms, 8 typhoons, and four super typhoons. This season was much more active than the previous season, although both seasons were below the Pacific typhoon average of 26. The season ran throughout 2011, though most tropical cyclone tend to develop between May and October. The season's first named storm, Aere, developed on May 7 while the season's last named storm, Washi dissipated on December 19.
The 2017 Pacific typhoon season was a below-average season in terms of accumulated cyclone energy and the number of typhoons and super typhoons, and the first since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir–Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.
Typhoon Muifa, known in the Philippines as Super Typhoon Kabayan, was a large, powerful and persistent typhoon which affected a number of countries in the Pacific, killing 22 and causing widespread damage worth US$480 million. It was the ninth named storm, third typhoon and the second super-typhoon of the 2011 Pacific typhoon season.
Severe Tropical Storm Talas, was an unusually large tropical cyclone that caused many deaths and severe damage to Japan. It was the 12th named storm and the 7th severe tropical storm of the 2011 Pacific typhoon season. Talas is known to have killed at least 82 people, and 16 more are still missing. The word Talas is a Filipino word meaning sharpness. It followed five months after Japan was hit by a large tsunami.
Typhoon Saola, known in the Philippines as Typhoon Gener, was a strong tropical cyclone affecting the Philippines, Taiwan and China. It was the ninth named storm and the fourth typhoon of the 2012 Pacific typhoon season. Saola is the name of a rare mammal found in Vietnam.
Typhoon Kai-tak, known in the Philippines as Severe Tropical Storm Helen, was a mild tropical cyclone that affected China, Vietnam and Laos. It was the seventh typhoon and the thirteenth named storm of the 2012 Pacific typhoon season. The storm killed 41 people and caused a sum of US$765 million in losses. Kai-tak can be tracked back to the broad area of disturbance embedded in a monsoonal trough that was first spotted, early on August 10. It was only at midnight, on August 16, when the JMA officially declared Kai-tak a typhoon. On the morning of August 17, the wind speed dropped to 60 knots and was no longer a typhoon. The typhoon caused heavy damage in China's two provinces, killing four people and causing huge economic loss. Kai-Tak slammed the northern Philippines triggering flash floods and landslides and killing at least ten people, one week after deadly monsoon rains battered the country. In Vietnam, Kai-Tak has stormed across the country's north bringing high winds and floods to several areas including the capital Hanoi.
Severe Tropical Storm Trami, known in the Philippines as Severe Tropical Storm Maring, was a tropical cyclone that brought heavy rains to Taiwan and East China during mid-August 2013. Trami also made a fujiwhara interaction with Tropical Depression 13W north of it. The storm also enhanced the southwest monsoon causing more than 20 casualties in the Philippines.
This timeline documents all of the events of the 2011 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean in 2011. Most of the tropical cyclones formed between May and November 2011. 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 (JMA). Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). 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 Matmo, known in the Philippines as Typhoon Henry, was the first tropical cyclone to impact Taiwan in 2014. It was the tenth named storm and the fourth typhoon of the 2014 Pacific typhoon season. The typhoon is believed to be one of the main reasons behind the crash of TransAsia Airways Flight 222, which occurred a day after it made landfall. There were fifty-four passengers on board and a crew of four, of whom 48 were killed. Taiwan News reported that "first suspicions hinted" the accident might be related to Matmo. The typhoon developed from a cluster of thundershowers consolidating around an area of low pressure in the doldrums. It initially followed a westward track, then made a sharp northwest turn before making landfall on Taiwan, and then China. After moving further inland, Matmo slowly curved back northeastwards and became extratropical before its remnants affected the Korean Peninsula.
Severe Tropical Storm Nanmadol, known in the Philippines as Severe Tropical Storm Emong, was a tropical cyclone that impacted southern Japan during July 2017. Nanmadol developed over in the Philippine Sea as a tropical depression on July 1, and strengthened into the third named storm of the 2017 typhoon season on July 3. After gaining organization, the system rapidly developed and intensified into a severe tropical storm and reached its peak intensity with a 10-minute maximum sustained winds of 100 km/h (62 mph) and a minimum barometric pressure of 985 hPa (29.1 inHg). On July 4, Nanmadol turned eastwards and made landfall near Nagasaki, Kyushu, just before it transitioned into an extratropical cyclone.
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 Hagupit, known in the Philippines as Severe Tropical Storm Dindo, was a Category 1 typhoon that heavily impacted Eastern China and South Korea in August 2020. It was the fourth named storm and the second typhoon of the annual typhoon season. The JMA began monitoring a tropical depression that developed in the Philippine Sea on July 30, with PAGASA assigning the name “Dindo” to the storm, later that day it strengthened into a tropical storm, according to the JMA. PAGASA issued its final advisory on Dindo early on August 3, as it moved out of their area of responsibility. Hagupit intensified into a typhoon on August 3, before making landfall in Wenzhou, China at 19:30 UTC that day at peak intensity. Hagupit subsequently weakened over China, before degenerating into an extratropical low on August 5. Hagupit's remnants persisted for another several days, as the storm moved eastward, before dissipating south of Alaska on August 14.
Typhoon Saudel, known in the Philippines as Typhoon Pepito, was a typhoon that affected the Philippines, Vietnam and Southern China in October 2020. It was seventeenth tropical storm and seventh typhoon of the 2020 Pacific typhoon season. The name Saudel was used for the first time, replacing Typhoon Soudelor in 2015, which caused serious damage in Taiwan and Mainland China. Saudel formed from a tropical disturbance east of the Philippines. The disturbance gradually organized and crossed the Philippines as a tropical storm. Once the system emerged into the South China Sea, it began to rapidly organize and intensify, becoming a typhoon early on October 22.
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.
