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. 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.
The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names. The Japan Meteorological Agency (JMA) [nb 2] will name a tropical cyclone if it has 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in the Philippine Area of Responsibility (PAR), located between 135°E and 115°E and between 5°N–25°N, regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) [nb 3] [nb 1] are given a number with a "W" suffix.

During the year, several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA, Vietnam's National Center for Hydro-Meteorological Forecasting and Taiwan's Central Weather Bureau.
Tropical Storm Risk (TSR) released their first forecast on May 7, predicting below average activity with 25 named storms, 15 typhoons and 7 intense typhoons. This was primarily due to the dominant El Niño event at the time, which was expected to transition into a weak or moderate La Niña by mid-2024. [3] In their July forecast, they slightly decreased the amount of storms and typhoons. [4]
The Pacific typhoon season began on May 22, when a tropical storm named Ewiniar formed southeast of Palau, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began. [7] Ewiniar tracked toward the Philippines, where it made nine landfalls in Homonhon Island; Giporlos, Eastern Samar; Basiao Island; Cagduyong Island; Batuan, Masbate; Masbate City; Torrijos, Marinduque; Lucena, Quezon and Patnanungan. It began to move over the warm tropical waters of Lamon Bay, where the JTWC and the JMA upgraded Ewiniar into a minimal typhoon. Ewiniar began transitioning to an extratropical cyclone while it is 719 km (447 mi) east-northeast of Kadena Air Base in Okinawa, Japan. On June 6, the remnants of Ewiniar would be absorbed by another extratropical cyclone, just off the coast of Alaska. On May 30, another tropical depression formed southeast of Haikou, China. The next day, at 03:00 UTC, JTWC designated the disturbance as Tropical Depression 02W. A few hours later, JMA assigned the name Maliksi as they upgraded 02W into a tropical storm. Shortly after being named, on May 31, Maliksi made landfall in Southern China. the JMA and JTWC discontinued warnings as Maliksi moved inland and dissipated on June 2. No storms formed in June for the first time since 2010.
After many weeks of inactivity, on July 13, a tropical depression formed east of Vietnam. Shortly after, it tracked into Vietnam, dissipating soon after. On July 19, two tropical disturbances recognized by the JTWC: one southeast of Manila and another east of Palau. Soon after, both disturbances developed into a depression, being named by PAGASA. The first one, west of Batangas, was named Butchoy while the second, east of Virac, was called Carina. Later that day, the JTWC followed suit, designating them both as depressions. The next day, the easternmost disturbance was named Gaemi by the JMA. On July 21, Butchoy also intensified into a tropical storm, assigning the name Prapiroon from the JMA. Prapiroon moved through the South China Sea as a mild tropical storm before landfall over Wanning, Hainan. Prapiroon moved through Gulf of Tonkin, where it further intensified into a severe tropical storm. Early on July 23, Prapiroon made its second and final landfall in Quảng Ninh, Vietnam. Rapid weakening ensued as Prapiroon moved inland and dissipated on the next day.
Being in a favorable environment in the Philippine Sea, Gaemi continues to strengthen into a severe tropical storm as it moves northeastward slowly. Early the next day, JMA upgraded Gaemi into a typhoon, the second to occur this season. JTWC also followed suit and upgraded Gaemi into a Category-1 typhoon. Owing to its warm sea surface temperature and low vertical wind shear, on July 24, Gaemi rapidly intensified into a Category-4 typhoon, with 10-minute sustained winds of 165 km/h (105 mph), equivalent to a very strong typhoon category by the JMA. Gaemi stalled and executed a counterclockwise loop near the coast, slightly weakening into a Category-3 typhoon. Overnight, Gaemi made landfall over Hualien, Taiwan at that intensity. The country's mountain ranges tore apart the storm's structure, causing Gaemi to weaken further into a Category-2 typhoon. The storm accelerated across the island and emerged into the Taiwan Strait, six hours after landfall. The next day, Gaemi made its final landfall at Xiuyu, Putian at Fujian Province as a weakening tropical storm. Moving inland, the storm rapidly weakened until it dissipated on July 27.
Even though Gaemi never made landfall in the Philippines, the storm's moisture would enhance the southwest monsoon. Heavy rainfalls were felt over Luzon and some parts of Visayas, leaving each region flooded. Overall, Gaemi caused 126 fatalities and $266 million worth of damages throughout its track.
On August 3, a low-pressure area developed east of Kadena Air Base. At 00:00 UTC, JMA recognize the disturbance as a depression. However, it downgraded to a remnant low on August 7. The convection later meandered south of Ryukyu Islands for a few days before JMA was reclassified again as a depression on August 11. JMA issued a gale warning the next day, citing that it would intensify in the following days. JTWC later followed suit and upgraded into a tropical depression. On August 13, the depression became a tropical storm, receiving the name Ampil from the JMA. Ampil gradually intensified in the Pacific Ocean, becoming a severe tropical storm. JMA upgraded Ampil into a typhoon two days later, with JTWC further recognized as a Category-2 typhoon. The next day, it strengthened into a Category-4 typhoon. The typhoon passed just south of Greater Tokyo Area before weakening and transitioning to an extratropical cyclone.
On August 5, a low-pressure area was formed in Bonin Islands. The disturbance was in an environment with low to moderate wind shear and warm SSTs. JTWC later classified the disturbance into a depression the next day, giving the designation 06W. Early on August 8, JMA upgraded the depression into a storm, naming it Maria. The storm further strengthened into a severe tropical storm on the same day. At the same time, JTWC reported that Maria had rapidly intensified into a typhoon due to strong equatorward and poleward outflow. However, on August 9, Maria weakened into a tropical storm as it moved northeastwards. On August 10, another area of low pressure formed just southeast of Maria. The JTWC would classify the disturbance as a subtropical depression in their next bulletin. Despite being in a marginal environment and high wind shear, JMA upgraded into a tropical storm, assigning the name Son-Tinh. The next day, JTWC announced that Son-Tinh became tropical, designating it as 07W. Son-Tinh weakened back into a depression before it dissipated on August 14.
On the morning of August 12, Maria made landfall in Iwate Prefecture as a tropical storm, bringing strong winds and dumping heavy rains in northern Japan. Maria then weakened into a depression after moving inland. The storm entered through the Sea of Japan, weakening further the next day. The JTWC issued its final warning after Maria was last noted west-northwest of Misawa, Japan. JMA continued to track as a depression before they issued their final warning at 04:15 UTC.
Activity became more active when an area of convection was formed on August 12 near the southwest of a nearby storm Son-Tinh. JMA would immediately recognize the disturbance as a depression. The next day, JTWC went to give its identifier of the depression, which was Tropical Depression 09W. Just like Ampil, on August 13, 09W intensified into a tropical storm, attaining the name Wukong from the JMA. Wukong was short-lived due to its poorly organized cloud tops. JTWC made its final warning on Wukong as it moved through cooler waters and dissipated on August 15.
On August 17, JMA recognized a tropical depression that formed east of Taiwan. The next day, PAGASA declared the system a tropical depression, assigning the name Dindo. The depression was named Jongdari three hours later upon formation. JTWC later followed suit and upgraded into a tropical storm. However, it did not last long and weakened into a depression as it nears the Korean Peninsula. On August 21, Both JMA and JTWC reported that Jongdari had dissipated as its low-level circulation center had faded when it moved over land. After Jongdari, a low-pressure area formed in the Northern Mariana Islands on the same day. The system intensified into a tropical storm on the next day and got the name Shanshan from the JMA. Shanshan later strengthened into a typhoon

On May 21, the Joint Typhoon Warning Center (JTWC) began tracking an area of atmospheric convection 441 km (274 mi) southeast of Palau, noting that the system was moving northwestward towards an environment favorable for tropical cyclogenesis. [8] In the following day, the disturbance became a tropical depression. [9] The depression would later enter PAR, assigning the name Aghon, a replacement name for Ambo. [10] At 18:00 UTC, the JTWC designated the depression as 01W, based on surface observations from Guiuan. [11] Aghon made landfall over Homonhon Island and subsequently Giporlos, Eastern Samar in the early morning of May 25 (PHT). [12] It made five more landfalls over Basiao and Cagduyong Islands of Catbalogan; Batuan in Ticao Island; Masbate City; and Torrijos, Marinduque. [13] At 12:00 UTC, 01W intensified into a tropical storm while it was still in Tayabas Bay, prompted the JMA to name the storm as Ewiniar. [14] In the morning of May 26 (PHT), the storm made its eighth landfall over Lucena, Quezon in Luzon island. [13] Ewiniar later intensified into a typhoon over Lamon Bay [15] The storm made its final landfall over Patnanungan in the Polillo Islands. [16] The typhoon left the PAR on May 29 and continued to weaken due to subsidence around the mid-latitude. [17] [18] On May 30, Ewiniar transitioned into an extratropical cyclone south-southwest of Yokosuka, Japan [19] Then at 18:00 UTC on May 31, Ewiniar entered the baroclinic zone and an area of high wind shear. [20]
Typhoon Ewiniar resulted in ₱1.03 billion ( US$ 20.88 million) in total damages in the Philippines, with ₱85.63 million ( US$ 1.74 million) to agriculture and ₱942.55 million ( US$ 19.14 million) to infrastructure, while also causing six deaths, injuring eight people, and impacting around 152,266 others. In Japan, heavy rainfall was observed in several regions, with a maximum of 52.5 mm (2.07 in) of rain being recorded in Miyake, Tokyo. [21] [22]

On May 29, the JTWC began tracking an area of convection located 406 km (252 mi) southeast of Haikou, China. Being in an area of warm waters and low vertical shear and having southerly outflow, the system sustained a weak circulation, inhibited from development by another area of convection near Mainland China. [23] It was recognized as a low-pressure area by the Japan Meteorological Agency (JMA) early the next day, [24] before the agency upgraded it to a tropical depression at 06:00 UTC. [25] Later that day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the depression since it had rapidly developed. [26] At 00:00 UTC the next day, the JTWC upgraded the system into a tropical depression, designating it as 02W. [27] Later, the JMA upgraded it into a tropical storm, and it was given the name Maliksi. [28] However, the JTWC reported that it did not intensify into a tropical storm as it was disorganized, with the circulation elongating. [29] [30] At 21:00 UTC on May 31, the JTWC discontinued warnings on the system as it made landfall in Southern China. [31] Soon after, the JMA downgraded Maliksi into a depression before being further downgraded by the agency as a low-pressure area as it tracked inland on June 2. [32] [33]
On May 30, the Hong Kong Observatory issued a No. 1 standby signal as the depression neared Hong Kong. [34] The next day, it upgraded the warnings into a No. 3 Strong Wind signal. [35] Although it was likely to not directly affect Taiwan, the Central Weather Administration noted that Maliksi's remnants were likely to merge with a frontal system and bring heavy rains to Taiwan over the weekend. [36] In Macau, the storm caused unstable weather, with the Meteorological and Geophysical Bureau issuing Typhoon Signal No. 3. [37] [38] In China, torrential rainfall occurred, peaking at 272.3 mm (10.72 in) somewhere in the Leizhou Peninsula. Additionally, heavy rain was recorded in Fujian, Zhejiang and Jiangxi. [39]

On July 13, the JTWC began tracking an area of convection 423 mi (682 km) east-southeast of Da Nang, Vietnam. At the time, the disturbance was in a marginal environment for development, with high vertical wind shear offsetting good divergence aloft alongside warm sea surface temperatures. [40] At 06:00 UTC of that day, the JMA designated the system as a tropical depression. [41] The JTWC then issued a TCFA on the system the next day, noting its symmetrical center had improved as it moves northwest, though convection was disorganized. [42] By 18:00 UTC the next day, the JTWC upgraded the system into a tropical depression, designating it 03W. [43] However, they issued their last warning on the depression early the next day as it moved over Vietnam and rapidly weakened. [44] Later that day, the JMA stopped tracking the depression as it dissipated. [45]

On July 15, the JTWC started to monitor a persistent area of convection roughly 623 km (385 mi) southeast of Manila, Philippines. At that time, the disturbance was in a favorable environment for development, with warm 29–30 °C (84–86 °F), sea surface temperatures, low wind shear and good equatorial outflow. [46] At 06:00 UTC the same day, the JMA designated the system as a low-pressure area. [47] Shortly after, the JMA designated it as a tropical depression. [48] The PAGASA declared the system a tropical depression a few hours later. Since the storm formed within the Philippine Area of Responsibility, the agency named it Butchoy. [49] The JTWC began issuing advisories on the system, classifying it as 04W. [50] It intensified into a tropical storm and was named Prapiroon by the JMA on June 21. [51] [52] A nascent eye feature became visible on microwave satellite imagery. [53] [54] The center of Prapiroon made landfall near Wanning, Hainan, with 1-minute sustained winds of 95 km/h (60 mph) on July 22. [54] After making landfall, the storm maintained its well-defined eye while moving across central Hainan. [55] Prapiroon soon encountered high wind shear and a dry environment, [56] and by 6:30 a.m. local time on July 23, it made its second landfall in Quảng Ninh, Vietnam. [57] [58] After the system moved inland, both the JMA and the JTWC ceased monitoring it on July 24. [59] [60]
Typhoon Gaemi and Prapiroon, along with its precursor, significantly impacted the southwest monsoon over the Philippines, leading to heavy rainfall that caused 23 deaths, 9 people missing, and US$18.9 million in damages across several countries. [61] [62] [63]

On July 17, the JMA reported that a low-pressure area had formed east of Palau. [64] Shortly after, both the JMA and the JTWC followed suit and upgraded the tropical depression, [48] with the latter designating the system as 05W. [65] The PAGASA followed suit a few hours later, recognizing the system as a tropical depression and naming it Carina. [66] Early the next day, the depression intensified into a tropical storm, and was given the name Gaemi by the JMA. [67] Due to a weak steering environment between the subtropical ridge to the northwest and east, the JTWC upgraded Gaemi to minimal typhoon around 21:00 UTC that day. [68] On July 24, Gaemi later rapidly intensified and peaked at Category 4-equivalent intensity on the Saffir-Simpson scale at 21:00 UTC on 23 July, with 1-minute sustained winds of 230 km/h (145 mph) by the JTWC, 10-minute sustained winds of 165 km/h (105 mph) by the JMA, and a central pressure of 940 hPa (27.76 inHg). [69] [70] After stalling and executing a tight counter-clockwise loop near the coast, [71] Gaemi slightly weakened into a below-equivalent typhoon status due to land interaction before it made landfall on the northeastern coast of Taiwan on July 24. [72] Gaemi accelerated as it moved across the island and emerged into the Taiwan Strait just six hours after making landfall. [73] Soon after, [74] the JTWC ceased issuing advisories on the system as it made its final landfall at Xiuyu, Putian in Fujian Province. [75] Once inland, the JMA continued tracking Gaemi until it weakened into a tropical depression on July 27. [76]
The southwest monsoon, combined with Tropical Storm Prapiroon, brought heavy rains to southern and northern Luzon, triggering widespread flash floods that resulted in at least 126 deaths and caused damage estimated at US$304 million across several countries. [77] [78] [79]

Category 4 typhoon (SSHWS) | |
Duration | August 3 – August 19 |
---|---|
Peak intensity | 155 km/h (100 mph) (10-min); 950 hPa (mbar) |
On August 3, the JTWC began tracking an area of convection 976 km (606 mi) east of Kadena Air Base on August 3. [80] At 18:00 UTC the same day, the JMA designated the system as a low-pressure area. [81] However, just six hours later, they upgraded the system as a tropical depression. [82] The depression weakened and was last noted by the JMA on August 7. [83] The disturbance later meandered south of the Ryukyu Islands for a few days before it was re-designated by the JMA as a tropical depression on August 11. [84] A few hours later, they recognized the system as a tropical depression, designating it as 08W. [85] Soon after, the JMA noted that it had intensified into a tropical storm and named it Ampil. [86] The JMA then reported that Ampil had intensified into a typhoon due to warm sea surface temperatures and low vertical wind shear on August 15. [87] The JMA reported that Ampil reached its peak intensity at 12:00 UTC that day with 10-minute sustained winds of 155 km/h (100 mph) and a central pressure of 950 hPa (28.05 inHg) before making its closest approach to Japan, and transitioned into an extratropical low on August 19. [88]
Ampil brought strong winds and coastal waves to western Alaska, while Tokyo experienced minimal damage according to NHK, although Kanagawa Prefecture saw several injuries; the remnants of Ampil also contributed to an atmospheric river as its moist core flowed into a low-pressure system, ultimately being absorbed into the Pacific jet stream and anticipated to impact California. [89]

Peak intensity | 100 km/h (65 mph) (10-min); 980 hPa (mbar) |
On August 5, the JMA stated that a tropical depression had formed. [90] Later that day, the JTWC began tracking it, noting the depression was in an environment with low to moderate wind shear, warm sea surface temperatures, and good equatorward outflow aloft. [91] At 09:00 UTC on August 6, the JTWC issued a TCFA on the disturbance, which was located 423 mi (682 km) north-northwest of Iwo Jima, along the eastern periphery of the monsoon gyre, [92] prior to it being designated as 06W. [93] The development of a central dense overcast and a ragged eye feature signified its intensification into a tropical storm, [94] leading the JMA to name it Maria on August 7. [95] Maria then turned northeastward, [96] and intensified into a severe tropical storm on August 8 due to a favorable environment for development. [97] Concurrently, the JTWC then reported that Maria had rapidly intensified into a minimal typhoon due to strong equatorward and poleward outflow. [98] However, Maria's wind field became more asymmetric, with its associated convection shifting northward, [99] causing Maria to weaken into a tropical storm on August 9. [100] Around 00:00 UTC on August 12, the storm made landfall Ōfunato, [101] a city in Iwate Prefecture, Japan with winds of 85 km/h (50 mph) before traversing northern Honshu and emerging into the Sea of Japan. [102] The JMA continued to monitor the system until it was last noted at 18:00 UTC on August 14. [103]
Record-breaking rainfall in Iwate Prefecture, with 19 inches (482.6 mm) in Kuji and 12.6 inches (320.0 mm) in Otsuchi—nearly double the average for August—led to controlled releases from the Taki Dam in Kuji, necessitating the evacuation of 8,300 people and the issuance of the highest evacuation alert level, though no damage or injuries were reported in association with Maria. [104]

On August 10, the JMA noted that a tropical depression had formed southeast of Severe Tropical Storm Maria. [105] A few hours later, the JTWC began tracking the system, noting that it could transition into a tropical cyclone despite intense wind shear. [106] Early the next day, they noted that the depression had transitioned into a subtropical cyclone. [107] As a result, a few hours later, the JMA named it Son-Tinh. [108] The next day, the JTWC noted that it had transitioned into a tropical storm, designating it 07W. [109] Soon after, the low-level circulation center became fully exposed with no deep convection existing near the center. [110] On August 13, Son-Tinh turned northwest along the western edge of a subtropical ridge. [111] Both the JMA and the JTWC stopped monitoring it as a tropical depression that day, [112] though the JMA continued to track it until it was last noted the following day. [113]

On 12 August, the JMA noted that a tropical depression formed southwest of Tropical Storm Son-Tinh. [114] A few hours later, strong convection south of the system’s low-level circulation center consolidated, which prompted the JTWC to issue a TCFA for the disturbance. [115] Soon after, they recognized the system as a tropical depression, designating it as 09W. [116] Satellite imagery revealed that a central dense overcast obscured the center, leading to the depression strengthening into a tropical storm named Wukong by the JMA, [117] although moderate vertical wind shear displaced the deep convection to the southeast. [118] [119] Wukong then shifted northwestward, following the eastern edge of a subtropical ridge, while also being affected by the shear and outflow from Typhoon Ampil to the southwest. [120] On August 15, both the JMA and the JTWC ceased monitoring the system, with the JMA reporting that Wukong had transitioned into an extratropical low due to moderate vertical wind shear and cooler sea surface temperatures. [121] [122]

On August 17, a low-pressure area east of Taiwan developed into a tropical depression. [123] [124] Soon after the development of a low-level circulation center and deep convection, the JTWC issued a TCFA for the disturbance. [125] A few hours later, PAGASA declared the system a tropical depression and named it Dindo, [126] while the JMA reported it had intensified into a tropical storm and named it Jongdari, [127] and the following day, the JTWC recognized it and designated it as 10W. [128] Jongdari became devoid of convection as it was displaced from its exposed low-level circulation center and turned north-northeastward along the western edge of a subtropical ridge. [129] Jongdari then weakened as it moved into the Yellow Sea and made landfall over the Korean Demilitarized Zone on August 20 before emerging into the Sea of Japan. [130] [131] The JTWC assessed the cyclone as having dissipated and ceased issuing advisories on the system, [132] while the JMA continued to monitor the system until it was last noted on August 21. [133]
In some parts of the southern islands of Jeju, Jongdari accumulated 60–130 millimetres (2.4–5.1 in) of rain as it moved closer to the coast. [134]

On August 20, the JMA reported that a low-pressure area had formed near the Mariana Islands. [135] At midnight on August 21, both the JMA and the JTWC upgraded the tropical depression, with the latter designating the system as 11W due to deep convection beginning to consolidate into a central dense overcast. [136] [137] Shortly after, the depression intensified into a tropical storm and was named Shanshan by the JMA due to low vertical wind shear and warm sea surface temperatures. [138] However, Shanshan's movement was nearly stationary due to the weak steering flow. [138] At 12:00 UTC on August 22, the JMA upgraded it to a severe tropical storm, citing Dvorak technique which indicated an estimate of 95 km/h (60 mph). [139] A ragged eye-like feature appeared on satellite imagery, and on August 24, both the JMA and the JTWC upgraded it to a minimal typhoon. [140] [141]
Many of the tropical depressions of the season failed to intensify into tropical storms, or even be numbered.
Within the basin, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. [151] The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee when they have 10-minute sustained winds of 65 km/h (40 mph). [152]
PAGASA names tropical cyclones which are active in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has already been named. [151] The names of significant tropical cyclones are retired by both PAGASA and the Typhoon Committee. [152] If the list of names for the Philippine region are exhausted, then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray. The names of significant tropical cyclones will be retired by both PAGASA and the Typhoon Committee in the spring of 2025. [152]
A tropical cyclone is named when it has 10-minute sustained winds of 65 km/h (40 mph). [153] The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of the ESCAP/WMO Typhoon Committee. [154] Retired names, if any, will be announced by the WMO in 2025, though replacement names will be announced in 2026. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.

This season, PAGASA will use its own naming scheme for storms that are active in their self-defined area of responsibility. [155] During this season, PAGASA is using the following list of names that was last used during 2020 and will be used again in 2028, updated with replacements of retired names, if any. [155] All of the names are the same as in 2020 with the exception of Aghon, Querubin, Romina and Upang, which replaced the names Ambo , Quinta , Rolly and Ulysses after they were retired. [155] The name Aghon was used for the first time this year.

The 2012 Pacific typhoon season was a slightly above average season that produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season, primarily due to Typhoon Bopha which killed 1,901 people in the Philippines. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2012, though most tropical cyclones typically develop between May and October. The season's first named storm, Pakhar, developed on March 28, while the season's last named storm, Wukong, dissipated on December 29. The season's first typhoon, Guchol, reached typhoon status on June 15, and became the first super typhoon of the year on June 17.
The 2013 Pacific typhoon season was the most active Pacific typhoon season since 2004, and the deadliest since 1975. It featured Typhoon Haiyan, one of the most powerful storms and one of the strongest landfalling tropical cyclones in history. It was an above-average season with 31 named storms, 13 typhoons, and five super typhoons. The season's first named storm, Sonamu, developed on January 4 while the season's last named storm, Podul, dissipated on November 15. Despite the activity, most of the first seventeen named storms before mid-September were relatively weak, as only two of them reached typhoon intensity. Total damage amounted to at least $26.41 billion (USD), making it at the time the costliest Pacific typhoon season on record; it is currently the fourth costliest, behind the 2018, 2019 and 2023 seasons.
The 2015 Pacific typhoon season was a slightly above average season that produced twenty-seven tropical storms, eighteen typhoons, and nine super typhoons. The season ran throughout 2015, though most tropical cyclones typically develop between May and November. The season's first named storm, Mekkhala, developed on January 15, while the season's last named storm, Melor, dissipated on December 17. The season saw at least one named tropical system forming in each of every month, the first time since 1965. Similar to the previous season, this season saw a high number of super typhoons. Accumulated cyclone energy (ACE) during 2015 was extremely high, the third highest since 1970, and the 2015 ACE has been attributed in part to anthropogenic warming, and also the 2014-16 El Niño event, that led to similarly high ACE values in the East Pacific.
The 2016 Pacific typhoon season is considered to have been the fourth-latest start for a Pacific typhoon season since reliable records began. It was an average season, with a total of 26 named storms, 13 typhoons, and six super typhoons. The season ran throughout 2016, though typically most tropical cyclones develop between May and October. The season's first named storm, Nepartak, developed on July 3, while the season's last named storm, Nock-ten, dissipated on December 28.
The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.
Typhoon Guchol, known in the Philippines as Super Typhoon Butchoy, was a powerful tropical cyclone which became the first typhoon to make landfall in Japan on June since 2004. The storm formed as tropical disturbance south-southeast of Pohnpei on June 7, and was upgraded to a tropical depression on June 10. The system later intensified in favorable conditions, and reached typhoon intensity on June 15. It reached peak intensity late on June 17, before making landfall over Japan as a typhoon on June 19. The system became extratropical shortly after traversing Japan and was last noted by the Japan Meteorological Agency on June 22.
Severe Tropical Storm Khanun, known in the Philippines as Tropical Storm Enteng, was the first tropical cyclone to directly impact Korea in two years. It is the 8th named storm, the 3rd severe tropical storm, and overall, the 13th tropical cyclone to be monitored by the Japan Meteorological Agency (JMA) during 2012. Khanun was also the first tropical storm to make a landfall over Korea in 2012. Khanun means "jack fruit" in Thai.
Tropical Storm Lingling, known in the Philippines as Tropical Depression Agaton, was a weak but deadly tropical cyclone that affected the Philippines in January 2014. The first named storm of the annual typhoon season, this early-season cyclone remained very disorganized throughout its lifespan. Lingling was the first major natural disaster in the Philippines after Typhoon Haiyan just two months earlier, as it caused widespread landslide incidents and floods in Mindanao, resulting in 70 deaths and damage amounting to over 566 million pesos on the island.
This timeline documents all of the events of the 2012 Pacific typhoon season. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. During the season, 34 systems were designated as tropical depressions by either the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. Since the JMA runs the Regional Specialized Meteorological Centre (RSMC) for the Western Pacific, they assigned names to tropical depressions which developed into tropical storms in the basin. PAGASA also assigned local names to systems which are active in their area of responsibility; however, these names are not in common use outside of the Philippines.
Typhoon 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.
This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.
Severe Tropical Storm Mekkhala, known in the Philippines as Severe Tropical Storm Amang, was an early-season tropical cyclone that made landfall over the Philippines in January 2015. Mekkhala killed three people in the Bicol Region and caused light crop damage. Notably, the storm disturbed Pope Francis’ visit to the country after the victims of Typhoon Haiyan on November 8, 2013. Although the storm also caused an airplane crash in Tacloban, nobody was hurt in the incident.
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.
Typhoon Noru was the second-longest-lasting tropical cyclone of the Northwest Pacific Ocean on record—behind only 1986's Wayne and tied with 1972's Rita—and the second-most-intense tropical cyclone of the basin in 2017, tied with Talim. Forming as the fifth named storm of the annual typhoon season on July 20, Noru further intensified into the first typhoon of the year on July 23. However, Noru began to interact with nearby Tropical Storm Kulap on July 24, executing a counterclockwise loop southeast of Japan. Weakening to a severe tropical storm on July 28, Noru began to restrengthen as it turned sharply to the west on July 30. Amid favorable conditions, Noru rapidly intensified into the season's first super typhoon, and reached peak intensity with annular characteristics on July 31. In early August, Noru underwent a gradual weakening trend while curving northwestwards and then northwards. After stalling off the Satsunan Islands weakening to a severe tropical storm again on August 5, the system began to accelerate northeastwards towards the Kansai region of Japan, making landfall in Wakayama Prefecture on August 7. Noru became extratropical over the Sea of Japan on August 8, and dissipated one day later.
Typhoon Nesat, known in the Philippines as Typhoon Gorio, was a strong tropical cyclone that impacted Taiwan and Fujian, China. It was the ninth named storm and the second typhoon of the annual typhoon season. After consolidating slowly for several days, Tropical Storm Nesat developed east of the Philippines on July 25. While experiencing favorable environmental conditions such as very warm sea surface temperatures and low wind shear, Nesat strengthened into a typhoon and reached its peak intensity on July 28. On July 29, the typhoon made landfall near the Taiwanese city of Yilan, before weakening to a severe tropical storm and making landfall again near Fuqing on China's east coast late the same day. Moving into July 30, Nesat continued to weaken under the effects of land interaction.
Typhoon Lan, known in the Philippines as Super Typhoon Paolo, was the third-most intense tropical cyclone worldwide in 2017, behind only hurricanes Irma and Maria in the Atlantic. A very large storm, Lan was the twenty-first tropical storm and ninth typhoon of the annual typhoon season. It originated from a tropical disturbance that the United States Naval Research Laboratory had begun tracking near Chuuk on October 11. Slowly consolidating, it developed into a tropical storm on October 15, and intensified into a typhoon on October 17. It expanded in size and turned northward on October 18, although the typhoon struggled to intensify for two days. On October 20, Lan grew into a very large typhoon and rapidly intensified, due to favorable conditions, with a large well-defined eye, reaching peak intensity as a "super typhoon" with 1-minute sustained winds of 249 km/h (155 mph) – a high-end Category 4-equivalent storm – late on the same day. Afterward, encroaching dry air and shear caused the cyclone to begin weakening and turn extratropical, before it struck Japan on October 23 as a weaker typhoon. Later that day, it became fully extratropical before it was absorbed by a larger storm shortly afterward.
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.
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; and the first during an El Niño event. 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.
Typhoon Prapiroon, known in the Philippines as Severe Tropical Storm Florita, was a Category 1 typhoon that worsened the floods in Japan and also caused impacts in neighboring South Korea. The storm formed from an area of low pressure near the Philippines and strengthened to a typhoon before entering the Sea of Japan. The seventh named storm and the first typhoon of the annual annual typhoon season. Prapiroon originated from a low-pressure area far off the coast of Northern Luzon on June 28. Tracking westwards, it rapidly upgraded into a tropical storm, receiving the name Prapiroon due to favorable conditions in the Philippine Sea on the next day.
