Typhoon Surigae,known in the Philippines as Super Typhoon Bising,was the strongest Northern Hemisphere tropical cyclone to form before the month of May,one of the most intense tropical cyclones on record and the strongest tropical cyclone worldwide in 2021. [1] [2] The second named storm,first typhoon and first super typhoon of the 2021 Pacific typhoon season,Surigae originated from a low-pressure area south of the Micronesian island of Woleai that organized into a tropical depression on April 12. At 18:00 UTC that day,it strengthened to a tropical storm and was named Surigae by the Japan Meteorological Agency (JMA). The formation of an eye and increasing winds prompted the JMA to upgrade the system to a severe tropical storm on April 13. The storm continued to gradually strengthen,and late on April 15,Surigae became a typhoon. Very favorable environmental conditions then allowed Surigae to begin a bout of rapid intensification;Surigae became a super typhoon the next day,and by April 17,the storm reached its peak intensity,with 10-minute sustained winds of 220 km/h (140 mph), [nb 1] 1-minute sustained winds of 315 km/h (196 mph),and a minimum pressure of 895 hPa (26.4 inHg). This made it the strongest pre-May typhoon on record. Afterward,the storm's weakening outflow and an eyewall replacement cycle caused Surigae to gradually weaken as its track shifted north-northwestward in the Philippine Sea. Following the eyewall replacement cycle,Surigae became an annular tropical cyclone on April 19,and restrengthened slightly. On April 22,the storm began to rapidly weaken as it accelerated northwestward into unfavorable environmental conditions,transitioning into a subtropical storm the next day. The subtropical system subsequently underwent extratropical transition,which it completed by April 24. Afterward,Surigae's extratropical remnant accelerated northeastward. On April 27,Surigae's remnant explosively intensified into a bomb cyclone near the Aleutian Islands,attaining hurricane-force winds. Afterward,the system gradually weakened as it turned eastward,slowing down in the process,before crossing the International Date Line on April 30 and fully dissipating on May 2.
Surigae is a North Korean word for the black-eared kite. Upon Surigae's naming,watches and warnings were issued for the island of Yap in the Federated States of Micronesia and the islands of Koror and Kayangel in Palau as well. The typhoon left US$4.8 million in damage in Palau after cutting off power,water,and destroying infrastructure. [nb 2] Later,warnings were raised for parts of the Philippines as the typhoon moved closer to the nation,with evacuations taking place in eastern regions of the Visayas. The storm killed at least 10 people and left another eight missing,in addition to causing at least ₱272.8 million (US$5.67 million) in damage in the Philippines.
During mid-April 2021, an area of atmospheric convection associated with a weak area of low pressure developed roughly 1,150 km (710 mi) south of Guam. By April 10, the disturbance had acquired nascent rainbands within an environment exhibiting low wind shear, warm sea surface temperatures (SSTs) between 28–29 °C (82–84 °F), and a well-established outflow, which was conducive for further tropical cyclogenesis. [4] Showers and thunderstorms continued to emerge around the circulation embedded within the disturbance. [5] The Japan Meteorological Agency (JMA) [nb 3] assessed the formation of a tropical depression near 5°N143°E / 5°N 143°E ; at the time, the newly designated system was moving slowly west-northwest around the southern periphery of a subtropical ridge. [6] [7] Due to its anticipated track into Philippine waters, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also began issuing advisories on the tropical depression on April 12. [8] The Joint Typhoon Warning Center (JTWC) [nb 4] issued a Tropical Cyclone Formation Alert (TCFA) later that day, projecting a high likelihood of a significant tropical cyclone developing. By April 13, the agency assessed the disturbance as a tropical depression. [10] [11]
A strong rainband along the depression's northern semicircle became prominent and coalesced around a robust and developing central dense overcast. [11] At 18:00 UTC on the same day, the JMA upgraded the system to a tropical storm and named it Surigae. [12] [13] Surigae was also upgraded to a tropical storm by the JTWC in the early hours of April 14, as the system progressed westward in the Philippine Sea. [14] [15] The storm continued to move slowly, remaining nearly stationary on April 14 – as it gradually intensified. [16] [17] Surigae's convective activity was initially displaced to the west of its center of circulation, though additional rainbands and thunderstorm development later covered the central vortex. [18] [19] On April 15, the JMA upgraded Surigae to a severe tropical storm as it moved closer to the island nation of Palau. [20] A formative eye became apparent on microwave satellite imagery later that day. [21]
By April 16, Surigae strengthened to a typhoon just north of Palau, making it the first typhoon of the 2021 Pacific typhoon season. [22] [23] The typhoon's convective activity had become tightly wound around its center, indicating additional strengthening. [24] On April 16 at 03:00 UTC, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) gave the storm the local name Bising as it entered the Philippine Area of Responsibility. [25] The system's eye became apparent through the central overcast, preceding a period of rapid intensification as Surigae progressed west-northwestward through a conducive environment. [26] [27] [28] Surigae's central dense overcast became colder and better-organized, with a well-defined ring of very cold cloud tops encircling a 26 km (16 mi) diameter eye. [29] Concurrently, an approaching trough produced a gap in the subtropical ridge of high pressure to the north, causing Surigae to slowly curve northwest as it quickly strengthened. [30]
On April 17, the JMA determined that Surigae's barometric pressure had rapidly fallen to 895 hPa (mbar; 26.43 inHg), as the storm reached its peak intensity. [31] [32] Its 10-minute maximum sustained winds reached 220 km/h (135 mph) according to the JMA, while one-minute maximum sustained winds reached 315 km/h (195 mph) according to the JTWC, making it equivalent to a Category 5 super typhoon on the Saffir–Simpson scale (SSHWS); [nb 5] [34] [35] the peak 1-minute sustained winds were also higher for the time of year than any previous typhoon on record. [31] The JTWC also estimated a minimum central pressure of 882 hPa (mbar; 26.05 inHg) for Surigae at the time. [36] Later that day, Surigae began an eyewall replacement cycle causing its eye to become less apparent on satellite imagery and its winds to slightly diminish. The trough to Surigae's north also impeded the typhoon's outflow, resulting in a decrease in environmental favorability for further intensification. [37] [38] On April 18, Surigae finished its eyewall replacement cycle; [38] Surigae acquired annular characteristics, bearing a symmetrical appearance and a large eye, which was largely surrounded by one large rainband, by the next day. [36]
By April 20, the prevalence of nearby dry air and upwelling of cold waters beneath the slow-moving typhoon caused its winds to decrease further. [39] [40] Some reorganization occurred when Surigae began to move north and away from the upwelled waters, with its large eye becoming less ragged; [39] however, additional entrainment of dry air originating from the mid-troposphere over Luzon caused Surigae's structure to degrade further on April 21. [41] Surigae turned northeast away from the Philippines later that day and weakened further, upon entering an environment with strong westerly winds in the upper troposphere. [42] [43] The once large and clear eye disappeared on April 22, leaving behind an increasingly-disheveled cluster of weakening showers and thunderstorms. [44] Soon afterward, all of Surigae's remaining convection was sheared to the east, as the storm moved over cooler waters. [45] As most of the remaining thunderstorms had dissipated, Surigae transitioned into a subtropical cyclone on April 23 due to interacting with an upper-level atmospheric trough as Surigae traversed a cold oceanic eddy. [46] Surigae began to undergo extratropical transition, a process it completed late on April 24, at which time the JTWC issued their final advisory on the system. [47] The JMA declared that Surigae had become extratropical a few hours later. [48]
As an extratropical cyclone, Surigae underwent explosive cyclogenesis on April 26, with its central pressure falling 44 hPa (mbar; 1.3 inHg) within 24 hours, while rapidly tracking northeastward. [49] While located to the east of Hokkaido, the system's ten-minute maximum sustained winds reached 130 km/h (80 mph) at 18:00 UTC that day, [50] and its central pressure bottomed out at 944 hPa (mbar; 27.88 inHg) six hours later. [51] Late on April 27, Surigae's remnant started to weaken while turning eastward. The next day, the system's forward motion significantly slowed down. On April 30, Surigae underwent a center reformation, with the original center of low pressure dissipating, and a new low-pressure center forming shortly afterward, which quickly dominated the system. [52] Afterward, Surigae's remnant continued moving eastward while gradually weakening, turning northeastward on May 1. On May 2, Surigae's remnant was absorbed into another extratropical cyclone, just south of the Alaskan Panhandle.
Due to the threat of the storm, a Tropical Storm Watch was issued for the island of Yap and Ngulu Atoll as well as for Koror and Kayangel in Palau on April 14, [53] where in the former, winds exceeded 30 mph (48 km/h). [54] The watch was upgraded to a Tropical Storm Warning for Ngulu Atoll later that day. [55]
As Surigae entered the Philippine Area of Responsibility, the PAGASA began issuing weather bulletins for the nearby storm. Initial forecasts by the agency suggested that the storm was less likely to make landfall over Luzon, and expected the storm to re-curve away from the Philippines. [25] [56] [57] On April 16, the Department of Transportation of the Philippines suspended all air and land travel to and from Visayas and Mindanao. [58] In the ensuing travel suspension, 2,507 individuals and 61 sea vessels were stranded in ports throughout the country. [59] Wave heights as high as 4.5 m (15 ft) were forecast near the eastern coasts of Visayas and Mindanao. [60] In order to avoid agricultural losses, Secretary William Dar of the Department of Agriculture encouraged farmers in the Bicol and Eastern Visayas regions to harvest their crops and for fishermen to refrain from fishing due to worsening oceanic conditions. [57] [61] At 15:00 UTC (23:00 PHT), the PAGASA began issuing Tropical Cyclone Wind Signal (TCWS) #1 for areas in Eastern Visayas and the Caraga Region, as well as for portions of Luzon six hours later. [62] [63]
On April 17, TCWS #2 was issued for Catanduanes and the entire island of Samar. [64] Flood advisories were also issued by the PAGASA for three regions in Visayas and Mindanao. [65] In preparation for the intense rains, the National Telecommunications Commission ordered telecommunications companies to prepare facilities in forecasted affected areas, including free calling and charging stations. [66] [67] [68] As early as April 17, preemptive evacuation began in the Bicol Region and the Samar province, [69] and by April 21, 169,072 people were evacuated in the Cagayan Valley, Bicol Region, Eastern Visayas, and Caraga. Flights in Daniel Z. Romualdez Airport and all Tacloban Airports were cancelled on April 18, and other domestic flights were also cancelled on the same day. [67] In addition, 10 domestic flights elsewhere were also cancelled that day. [59] Schools and work activities were suspended in the Bicol Region till April 20. [70] ₱1.5 billion (US$31.05 million) worth of standby funds were prepared for disaster response. [71]
Locally heavy rainfall occurred in parts of Palau and Yap for several days. [72] Surigae brought sustained winds of up to 80 km/h (50 mph) and gusts up to 135 km/h (84 mph) to Palau, causing power outages across the island. [73] [74] [75] Large swells from the developing storm brought coastal flooding to Koror and Yap. Residents in those areas were advised to avoid reef lines in the north and west, and to take caution on beaches due to rip currents and large waves. [76] Surigae was the closest typhoon to pass near the island of Palau since Typhoon Haiyan. [77] Restaurants, sporting events and other services were closed in Palau as Surigae approached closer– yet schools remained open. [77] Schools were not suspended until power had been cut off across much of the entire country. [77] Water and cellular services were also downed. [77] There was criticism for the lack of news coverage on the typhoon in Palau most notably. [77] 125 homes across the country were destroyed, while at least 1,500 sustained minor damage. [75] The entire population of Palau, consisting of approximately 18,008 people, was impacted by the typhoon. [75] At least US$2 million worth of infrastructure alone was damaged in Palau. [78] The total amount of damage across health, infrastructure, education, food, communication, utilities and other sectors was assessed at US$4.8 million. [75] President of Palau Surangel Whipps Jr. issued a national state of emergency on April 18. [79] The United States Agency for International Development (USAID) provided US$100,000 for immediate assistance to support those affected. [80] In Guam, emergency supplies were being prepared and donated to communities in need in Palau. [79]
Five people in a boat were rescued off the coast of Pujada Bay due to dangerous sea conditions produced by Surigae. [81] Another boat with two fishermen aboard capsized during midnight on its way to Bantayan Island, with both of two fishermen having to swim back to shore. [82] On April 19, Surigae forced the cargo ship LCU Cebu Great Ocean, carrying twenty crew members and nickel ore, to run aground on the coast of the Province of Surigao del Norte, in the southern Philippines. [83] [84] At least six of the crew members were found dead, while seven were rescued; the search continues for another missing seven crew members. [85] [86] Heavy rain from the outer bands of Surigae battered Eastern Visayas and the Bicol Region as it passed around 345 km (214 mi) to the east of Catanduanes. [87] Widespread rainfall totals of up to 8–12 inches (200–300 mm) occurred in the eastern Philippines, while 20.13 inches (511 mm) of rain fell in Virac, Catanduanes and surrounding areas. [88] A funnel cloud was also briefly reported in Camarines Sur. [89] Twenty-two barangays were flooded in Eastern Visayas, and in the municipality of Jipapad, flooding reached 4 metres (13 ft). Power interruptions were experienced in Central Visayas, Eastern Visayas and in Eastern Samar, power was interrupted for the whole province. [67] 109,815 people were displaced by flooding and landslides in the Bicol Region. [90]
Ten deaths were reported due to the typhoon. One person in Southern Leyte and another in Cebu died due to fallen coconut trees. [91] [92] Six crew members of the LCU Cebu Great Ocean were found dead after the ship ran aground in the southern Philippines; another seven crew members remain missing. [85] [86] Another person remains missing in Northern Samar. [93] 13 others were injured. [91] A total of 3,385 houses were damaged in the Bicol Region, Eastern Visayas and Caraga, with 158 totally destroyed. Agricultural damage in the Bicol Region and Eastern Visayas reached ₱261.9 million (US$5.43 million), while infrastructural damage totaled ₱10.87 million (US$226,000). [94] 63 cities experienced power interruptions; however, power was restored in 54 of those cities. [95]
Following the passage of Surigae, the Department of Social Welfare and Development (DSWD) and local government units provided assistance worth approximately ₱6.52 million (US$135,000) to those affected in Cagayan Valley, the Bicol Region and the Eastern Visayas. [94] Schools and workplaces fully reopened by April 20. [96]
The influence of Surigae caused gusts in North Sulawesi that reached 23 mph (37 km/h). [97] Large waves of 13.1–19.8 feet (4.0–6.0 m) affected the coastal waters of the Sitaro Islands Regency, Sangihe Islands Regency, the Talaud Islands and the northern Molucca Sea. [98] Surigae made its closest approach to Taiwan on April 22. The typhoon's outer bands brought much-needed rainfall to central Taiwan, which was going through its worst drought in 56 years. There were also reports of hail. [99] Large waves up to 4.2 m (14 ft) tall generated by Surigae were recorded along Taiwan's east coast on April 21. [100]
Typhoon Neoguri, known in the Philippines as Typhoon Ambo, was the earliest tropical cyclone on record to strike China. The first named storm in the 2008 Pacific typhoon season, named after the Korean word for raccoon dog, it formed from a low pressure area on April 13 to the east of the Philippine island of Mindanao, and after crossing the island it intensified into a tropical storm in the South China Sea. Environmental conditions allowed for quick strengthening, with Neoguri attaining typhoon status on April 16. The typhoon reached its peak intensity on April 18 as it approached the island of Hainan, and subsequently it turned northward. Due to increased wind shear and cooler waters, Neoguri rapidly weakened and made landfall as a minimal tropical storm in southern China on April 19.
Tropical Storm Higos, known in the Philippines as Tropical Storm Pablo, was a tropical storm during the 2008 Pacific typhoon season. The name "Higos" is the Chamorro word for fig.
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 2019 Pacific typhoon season was the costliest Pacific typhoon season on record, just ahead of the previous year and 2023. The season featured fairly above-average tropical cyclone activity for the second consecutive year, producing 29 named storms, 17 typhoons, and five super typhoons, also, it was the final season of the Western Pacific's consecutive active typhoon seasons that started in 2013. The season's first named storm, Pabuk, reached tropical storm status on January 1, becoming the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record that was held by Typhoon Alice in 1979. The season's first typhoon, Wutip, reached typhoon status on February 20. Wutip further intensified into a super typhoon on February 23, becoming the strongest February typhoon on record, and the strongest tropical cyclone recorded in February in the Northern Hemisphere. The season's last named storm, Phanfone, dissipated on December 29 after it made landfall in the Philippines.
The 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. 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.
Severe Tropical Storm Rumbia, known in the Philippines as Tropical Storm Gorio, was a tropical cyclone that brought widespread flooding in areas of the Philippines and China late June and early July 2013. The sixth internationally named storm of the season, Rumbia formed from a broad area of low pressure situated in the southern Philippine Sea on June 27. Steadily organizing, the initial tropical depression moved towards the northwest as the result of a nearby subtropical ridge. On June 28, the disturbance strengthened to tropical storm strength, and subsequently made its first landfall on Eastern Samar in the Philippines early the following day. Rumbia spent roughly a day moving across the archipelago before emerging into the South China Sea. Over open waters, Rumbia resumed strengthening, and reached its peak intensity with winds of 95 km/h (50 mph) on July 1, ranking it as a severe tropical storm. The tropical cyclone weakened slightly before moving ashore the Leizhou Peninsula late that day. Due to land interaction, Rumbia quickly weakened into a low pressure area on July 2 and eventually dissipated soon afterwards.
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 Melor, known in the Philippines as Typhoon Nona, was a powerful tropical cyclone that struck the Philippines in December 2015. The twenty-seventh named storm and the eighteenth typhoon of the annual typhoon season, Melor killed 51 people and caused ₱7.04 billion in damage.
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.
Tropical Storm Kai-tak, known in the Philippines as Tropical Storm Urduja, was a late-season tropical cyclone that affected the Philippines during December 2017. The twenty-sixth named storm of the 2017 Pacific typhoon season, Kai-tak started as a tropical depression near Palau on December 11. Slowly intensifying, the system became a tropical storm on December 14. Due to its slow motion, Kai-tak made landfall in Samar on December 16 and traversed the Philippine Islands. Kai-tak later moved in a west-southwestward direction until it dissipated on December 23 near Malaysia.
The 2021 Pacific typhoon season was the second consecutive to have below average tropical cyclone activity, with twenty-two named storms, and was the least active since 2011. Nine became typhoons, and five of those intensified into super typhoons. This low activity was caused by a strong La Niña that had persisted from the previous year. The season's first named storm, Dujuan, developed on February 16, while the last named storm, Rai, dissipated on December 21. The season's first typhoon, Surigae, reached typhoon status on April 16. It became the first super typhoon of the year on the next day, also becoming the strongest tropical cyclone in 2021. Surigae was also the most powerful tropical cyclone on record in the Northern Hemisphere for the month of April. Typhoons In-fa and Rai are responsible for more than half of the total damage this season, adding up to a combined total of $2.02 billion.
The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
Tropical Storm Bolaven, known in the Philippines as Tropical Storm Agaton, was an early-season tropical cyclone that affected southern parts of the Philippines in January 2018. The first named storm of the 2018 Pacific typhoon season, Bolaven formed as a tropical depression near Palau on December 29, 2017. The system moved generally westwards without intensifying and made landfall over northeastern Mindanao on January 1, 2018. The depression spent the next day traversing the Philippines, making four more landfalls in the Visayas and one in Palawan. The system strengthened into a tropical storm on January 3 as it entered the South China Sea, receiving the name Bolaven. However, Bolaven weakened back to a tropical depression just a day later amid a marginal environment and dissipated on January 4 east of Vietnam.
Tropical Storm Sanba, known in the Philippines as Tropical Storm Basyang, was a weak tropical cyclone that affected southern and central parts of the Philippines in mid-February 2018. Sanba developed as a tropical depression in the open Pacific Ocean on February 8. The system moved generally westward while slowly developing, finally attaining tropical storm status on February 11. Soon after, wind shear caused the system to lose organization and remain as a minimal tropical storm through February 11 and 12. During this time, Sanba moved westwards then west-northwestwards, making landfall over northeastern Mindanao on February 13. The system weakened into a tropical depression before making another landfall in southeastern Negros later that day. After traversing the Philippine Islands, Sanba failed to reorganize significantly in the Sulu Sea and dissipated two days later west of Palawan.
Tropical Depression Usman was a weak but deadly tropical cyclone that impacted the southern Philippines in December 2018. Tropical Depression Usman originated first as a low-pressure area to the east of Palau on December 23. Slowly intensifying, the system became a tropical depression two days later. The system maintained its intensity while moving in a general west-northwestward direction approaching the eastern portion of the Philippine islands. However, due to unfavorable conditions, the depression weakened into a remnant low on December 29, while making landfall over Eastern Samar thereafter.
Typhoon Wutip, known in the Philippines as Tropical Depression Betty, was the most powerful February typhoon on record, surpassing Typhoon Higos of 2015. The third tropical cyclone, second tropical storm, and the first typhoon of the 2019 Pacific typhoon season, Wutip originated from a low-pressure area on February 16, 2019, that generally tracked westward, passing just south of the Federated States of Micronesia (FSM), before organizing into a tropical depression on February 18. The depression was later classified a tropical storm a day later, attaining the name Wutip from the Japan Meteorological Agency. The storm gradually intensified as it turned northwest, before it underwent rapid intensification on February 23, while passing to the southwest of Guam, and reached its first peak intensity. With winds of 270 km/h (165 mph) estimated by the Joint Typhoon Warning Center, Wutip became the first Category 5-equivalent super typhoon on record in the month of February. Wutip underwent an eyewall replacement cycle shortly afterward and weakened. The storm finished its cycle on February 24, rapidly intensifying once again. Wutip reached a secondary peak intensity the following day, again attaining Category 5-equivalent winds. Thereafter, Wutip rapidly weakened for the rest of its lifespan from strong vertical wind shear, before dissipating over the Philippine Sea on March 2.
Typhoon Vongfong, known in the Philippines as Typhoon Ambo, was a strong tropical cyclone that impacted the Philippines in May 2020. Beginning as a tropical depression on May 10 east of Mindanao, Vongfong was the first storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow northward course, strengthening into a tropical storm on May 12 and curving west thereafter. The next day, Vongfong entered a period of rapid intensification, becoming a typhoon and attaining 10-minute maximum sustained winds of 150 km/h (93 mph). The storm made landfall at this intensity near San Policarpo, Eastern Samar, at 04:15 UTC on May 14. The system tracked across Visayas and Luzon, making a total of seven landfalls. Persistent land interaction weakened Vongfong, leading to its degeneration into a tropical depression over the Luzon Strait on May 17.
Typhoon Maysak, known in the Philippines as Typhoon Julian, was a deadly, damaging and powerful tropical cyclone that struck the Ryukyu Islands and the Korean Peninsula in September 2020. The third typhoon of the 2020 Pacific typhoon season, Maysak formed from a tropical disturbance. The disturbance gradually organized, receiving the name Julian from PAGASA as it became a tropical depression. As the depression strengthened, the JMA subsequently named the system Maysak. Maysak rapidly intensified into a strong typhoon before weakening and making landfall in South Korea.
Severe Tropical Storm Maliksi, known in the Philippines as Severe Tropical Storm Domeng, was a tropical cyclone in June 2018 that brought rainfall to the Philippines and Japan. It caused 2 deaths and prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The fifth named storm and 4th tropical cyclone in the Philippine Area of Responsibility (PAR), it was first noted as an area of convection in the South of Palau on May 31.
Typhoon Jelawat, known in the Philippines as Tropical Storm Caloy, was a powerful typhoon that affected the Caroline Islands in March 2018. The third tropical storm and the first typhoon of the 2018 Pacific typhoon season, Jelawat originated as a tropical disturbance that struck the Federated States of Micronesia before organizing into a tropical depression on March 24. It further intensified into a tropical storm on the following day, according to the Japan Meteorological Agency, receiving the name Jelawat. Drifting northward, the storm remained unorganized while staying east of the Philippines, though environmental conditions became more favorable along its path. On March 29, Jelawat took an unexpected sharp turn east as it intensified into a typhoon. Upon shifting northeast, Jelawat rapidly intensified on March 30 due to low vertical wind shear and substantial outflow, peaking as a Category 4-equivalent super typhoon. Shortly afterward, the storm began to weaken as wind shear sharply increased, falling below typhoon strength on March 31. The storm transitioned into a subtropical cyclone on April 1, before dissipating on that same day.
