User:Jarda2020/2023 Pacific typhoon season

The 2023 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2023, though most tropical cyclones typically develop between May and October.

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) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h anywhere in the basin, whilst 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) are given a number with a "W" suffix.

Seasonal forecasts
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 and Taiwan's Central Weather Bureau. The first forecast was released by PAGASA on December 22, 2022, in their monthly seasonal climate outlook predicting the first half of 2023. They predicted that only 0–3 tropical cyclones were expected to form or enter the Philippine Area of Responsibility between January and March, while 1–4 tropical cyclones are expected to form between April and June. PAGASA also stated that ongoing La Niña conditions could last until it transitions back into ENSO-neutral conditions by the second quarter of 2023.

Tropical Storm Pakhar (Amang)
On April 2, the JTWC noted the persistence of an area of convection 359 nmi west-northwest of Palau. Since the storm's conditions were favorable for development, the JMA included the storm in its weather summary as a tropical depression off the coast east of Visayas later that day. Around the same time, the PAGASA announced that the system had developed into a tropical depression, was named Amang by the agency. The PAGASA began issuing Tropical Cyclone Bulletins (TCBs) for the storm later that day. On the next day, the JTWC later issued a TCFA for the system. At 03:00 UTC, the agency upgraded it to a tropical depression and assigned it the identifier 01W. On April 3, the JMA upgraded it to a tropical storm, assigning it the name Pakhar. It made its first landfall in Calicoan Island, Guiuan at 07:30 PHT (23:30 UTC). Pakhar then stalled in the Leyte Gulf for hours before making its second landfall in Basey, Samar. Pakhar then weakened into a tropical depression after lingering over the islands of Samar and Leyte, and the PAGASA removed all warning signals as it dissipated into a remnant low on the evening of April 6.

From April 2 to April 4, the storm meandered along the Eastern Visayas region, dumping heavy rain on the region. The PAGASA raised storm signals up to Signal No. 2 during the storm's onslaught. Cebu City was placed under a state of calamity following the heavy rain. Pakhar killed 76 people, injured eight people and left 134 people missing, and capsized a cargo boat in Ormoc following strong rains, winds, and flash floods that also displaced over 136,390 individuals. The Department of Agriculture estimated agricultural damage to reach ₱3.27 billion, while the Department of Public Works and Highways estimated infrastructural damage at ₱1.45 billion. Total damage from the storm is thus valued at ₱4.72 billion (US$90.8 million).

Tropical Depression 02W (Betty)
On April 8, the JTWC noted a persistent area of convection in the Philippine Sea, approximately 184 nmi west of Palau. The JTWC issued a TCFA for the convection on April 9, as it further developed in an environment with low vertical wind shear and warm sea surface temperatures. Just three hours later, the agency recognised that the area of convection had quickly consolidated into a tropical depression and assigned it with the identifier of 02W. Around the same time, the JMA had also recognised the storm as a tropical depression while it was to the east of Mindanao. Since the storm developed within the Philippine Area of Responsibility, the PAGASA immediately named the storm Betty once the agency recognized it as a tropical depression as well, and later raised Signal No. 2 warnings for areas in Mindanao. In the early hours of April 10, the JTWC upgraded the system into a tropical storm, with the PAGASA following suit hours later. Later that day, Betty's low-level circulation center became exposed due to wind shear, and it lost organization. At 8:20 p.m. Philippine Standard Time (12:20 UTC), Betty made landfall in Baganga, Davao Oriental as a weakening tropical storm. It quickly degraded as soon as it made landfall, with both the JTWC and the PAGASA downgrading it to a tropical depression at 15:00 UTC. At 03:00 UTC on that day, the PAGASA reported that the system degenerated to an area of low-pressure in the vicinity of Piagapo in Lanao del Sur, thus lifting all warning signals on Mindanao and issuing their final advisory. On April 12, the system dissipated over the Sulu Sea, and both the JMA and the JTWC issued their final advisories on the storm.

In preparations for the storm, the local government of Davao Occidental raised a blue alert on April 11, with the authorities in the area preparing rescue equipment in case of emergency. The PAGASA also warned small vessels near the area to stay away from the rough seas caused by the storm. Schools were ordered to be suspended from that day in Davao Occidental, including the submission of modules. When Betty made landfall, it caused widespread rains and flooding across Mindanao and Southern Visayas. Gusty winds were also felt in parts of Mindanao where the storm passed. In Baganga, some trees were knocked down by strong winds, while strong winds with heavy rainfall were reported in Cateel and Boston, all in the province. Three men and a carabao were required to be rescued from the rising Kabacan River in the early hours of April 12; they were successfully released safely from the said river. An evacuation center in South Upi, Maguindanao were reported to be flooded and some crops near the center were submerged in floodwaters, all due to a rising river near the area. Agricultural damages were estimated at ₱23.2 million (US$486,000).

Severe Tropical Storm Sanvu (Chedeng)
On April 29, the JTWC reported in its TCFA (Tropical Cyclone Formation Alert) that a low pressure area near the Philippines was able to develop because of warm waters and low wind shear. The agency designated it as Invest 93W. The JMA and the PAGASA then classified the disturbance as a tropical depression, with the latter assigning the name Chedeng to the system. The JTWC upgraded the system to a tropical depression a day later, at 00:00 UTC on April 30, and it was given the designation 03W. At the same time, the JMA upgraded the typhoon to a tropical storm, and was named Sanvu. On 17:10 UTC on May 1, Nalgae made its first landfall at Virac, Catanduanes, followed by another landfall at Caramoan, Camarines Sur just thirty minutes later. It crossed the Bicol Region and exited into the Sibuyan Sea, and later made its third landfall in Buenavista, Quezon, maintaining its strength as it did so. Sanvu then headed southwestward and struck Mogpog in the island province of Marinduque, then later crossed the Sibuyan Sea again and made its fifth landfall in Sariaya, once again in the province of Quezon, later passing into Laguna. Sanvu then passed through Metro Manila and Rizal, heading into Bulacan by evening of May 2. By the next day, Sanvu weakened into a tropical storm in the West Philippine Sea, but re-intensified into a severe tropical storm a few hours later, and exited the Philippine Area of Responsibility a day later. Upon its exit from Philippine jurisdiction, Sanvu then intensified into a Category 1-equivalent typhoon on JTWC; however, the JMA maintained its severe tropical storm classification for the system. It then approached the Pearl River Delta, prompting officials in Hong Kong and Macau to raise Signal No. 8 from May 3 to 4.

Severe Tropical Storm Mawar (Dodong)
Early on June 4, a tropical depression developed about 1090 km southwest of Guam. Over the next couple of days, the depression moved northwestward and gradually developed in an area of moderate windshear. Late on June 5, the center passed over the Philippine island of Mindanao but maintained its deep convective banding, which prompted the JTWC to issue a Tropical Cyclone Formation Alert (TCFA). During the next day, PAGASA named the depression Dodong. The system moved westwards into the Sulu Sea, and the JTWC initiated advisories on the system as 04W. The JMA reported later that day that the depression intensified into Tropical Storm Mawar, before the JTWC followed suit early on June 7 as the system continued to consolidate. After further strengthening, Mawar intensified into a severe tropical storm on June 8, with 10-minute sustained winds of 95 km/h. Early on June 9, the JMA and JTWC reported that Sonamu weakened into a tropical depression. The system dissipated on June 12 about 110 km west of Bintulu in Sarawak.

Within the Philippines, 1 person drowned while another person died after being hit by a coconut tree. A passenger ship was stranded near the coast of Dumaguete City on June 6 before being rescued.

Tropical Depression 05W
Tropical Depression 05W was a short lived tropical depression that was first noted during as a tropical disturbance during June 11, while it was located about 685 km to the northeast of Hagåtña, Guam. Over the next day, the system quickly developed into a tropical depression, within marginal environment for further development, before it was declared to be a tropical depression on June 12. However, the system quickly weakened and was last noted as it dissipated over the Pacific Ocean to the northeast of Guam during the next day.

Typhoon Guchol (Egay)
A low-pressure area west of Luzon developed into a tropical depression on June 21. At 20:00 PHT (12:00 UTC), the PAGASA had recognized the storm's development into a tropical depression, began issuing advisories, and named the system Egay. The following day, the JTWC issued a TCFA for the system. Egay remained almost stationary in the South China Sea before slowly moving northwestwards, eventually leaving the Philippine Area of Responsibility by 15:00 UTC. As the PAGASA issued its last bulletin on the tropical depression, the JTWC began issuing warnings for the storm and was given the designation 06W. Later, the Japan Meteorological Agency upgraded Egay into a tropical storm, naming it Guchol. Chaba continued to intensify in the South China Sea, later being upgraded into a severe tropical storm east of Hainan. Typhoon Guchol's outer rainbands produced at least three tornadoes, which impacted Shantou, Chaozhou, and Foshan. On June 24 at 21:00 UTC, the JTWC upgraded Guchol to a typhoon, with the JMA doing the same 3 hours later on June 25 at 0:00 UTC. Later that day at 07:00 UTC, it made landfall on Maoming. Shortly after its landfall, both the JMA and the JTWC assessed that Guchol lost typhoon status, downgrading Guchol to a severe tropical storm and to a tropical storm respectively. The JTWC then issued their final warning on Guchol at 15:00 UTC. Shortly after, the JMA downgraded Guchol to a tropical storm; it was further downgraded to a tropical depression on June 27 at 06:00 UTC.

160 nmi southwest of Hong Kong, the Fujing 001, a crane vessel tasked in assisting with the construction of an offshore wind farm, split in half and quickly sunk—leaving 26 crew members missing. Three of the 30 crew members were rescued, seen in a video published online by the Hong Kong Government Flying Service. Another person was rescued by June 27, bringing the total number of people rescued to four. Twelve bodies from the ship were recovered. More than 400 flights were suspended in Hainan; one person was injured in Macau.

Tropical Storm Talim (Falcon)
A tropical disturbance formed east of the Philippines on July 4. Later that day, it was given the name Falcon by the PAGASA. Early the next day, it intensified into Tropical Storm Talim as it made several thunderstorms. Its remnants stayed east of Taiwan on July 8 and it finally dissipated on July 9.

On July 6, a lightning incident within the Philippine province of Ilocos Sur, left two people dead and two others injured. Torrential rains over southern Fujian Province triggered significant flooding. A 24-hour peak of 505.3 mm was measured in Mei Village, with an hourly maximum of 132.3 mm. Many homes were inundated and several roads were washed out. Some areas experienced 1-in-500-year flooding. Approximately 20.28 million people were affected by the storm, 8.92 million of whom were temporarily relocated. At least one person was killed and another was reported missing. An unusually intense thunderstorm associated with Talim produced a prolific lightning event over Xiamen, with 411 strikes recorded in two hours.

Severe Tropical Storm Doksuri (Goring)
In late June, a low-pressure area persisted within the ITCZ east of the Philippines. Initially tracking southward, the disturbance moved east and then recurved to the west. Steadily organizing, the disturbance became a tropical depression on July 6, moving to the northwest due to a nearby ridge. On July 7, the disturbance strengthened into Tropical Storm Doksuri, and the next day made its first landfall on Eastern Samar in the Philippines. Doksuri spent roughly a day moving across the archipelago before emerging into the South China Sea, where it resumed strengthening to a peak of 95 km/h on July 9, a severe tropical storm. The storm weakened slightly before moving ashore the Leizhou Peninsula in China late that day. Due to land interaction, Doksuri quickly weakened into a low-pressure area on July 11 and dissipated soon after.

Upon landfall in the Philippines, Doksuri caused extensive flooding across multiple islands, which disrupted transportation and displaced thousands of people. Power outages resulted from the heavy rain and strong winds, and seven deaths were reported within Concepción, Iloilo after an unnamed motorbanca capsized. At its landfall in China, Doksuri damaged large swaths of agricultural cropland and destroyed at least 112 buildings, causing ¥7.68 million in damage.

Tropical Depression 09W
On July 8, the JTWC noticed an area of convection with a consolidating low-level circulation center at approximately 7 nmi to the south of Manila, Philippines. The system then subsequently moved over Luzon and emerged into the South China Sea, where it organized but its circulation remained broad, having two distinct vortices present in satellite imagery. The JMA then upgraded the system into a tropical depression by 00:00 UTC on July 11. The JTWC designated the system as a tropical storm six hours later, assigning the system as 09W. The storm did not intensify further, according to the JMA, and by 02:50 UTC on July 13, 09W made landfall on the coastal areas of Xuwen County in Zhanjiang, Guangdong. The JTWC subsequently canceled the TCFA and downgraded its formation chances to medium. The JMA then downgraded the storm into a tropical depression as it moved inland in Vietnam by the next day, and was last noted six hours later the same day.

Heavy rainfall in Vietnam caused flash flooding which resulted in the deaths of six people. The northern region of the country experienced torrential rainfall of about 20 to 50 mm. The storm also caused agricultural damages of an estimated ₫2.5 million (US$106,850) after about 30,000 lobsters have died due to the effects of the storm.

Tropical Storm Khanun
A low-pressure area developed into a tropical depression northwest of Iwo Jima on July 13. After JMA named the system Khanun, the JTWC followed suit in an unofficial bulletin, classifying this system as a tropical storm. However, according to the agency, because of colder waters, the storm returned to the Pacific Ocean after threatening the southern coast of Japan without causing major impacts.

In preparation for Khanun, government officials in Tokyo warned of heavy rains and strong winds. About 72,000 residents were evacuated in Shizuoka; two landslides were reported which isolated five houses. Power outages affected 1,200 homes in Shimizu and another 2,200 were affected in Kakegawa. Parts of the Shin-Tōmei Expressway, connecting Tokyo to Nagoya, were closed as a result of heavy rains, while tunnel speed limits were lowered. Rainfall also affected flights and bullet train services, the latter of which affecting 92,000 people. An elderly man in Hamamatsu sustained forehead injuries after being knocked down by strong winds.

Homes in Central Japan were destroyed.

Typhoon Lan (Hanna)
At 06:00 UTC on July 17, the JTWC started to monitor an area of low pressure west-northwest of Guam. Located in an area favorable for intensification with warm sea surface temperatures as its outflow improved, the system struggled to develop under moderate wind shear before gradually intensifying, with the agency issuing a Tropical Cyclone Formation Alert at 20:30 UTC on the next day. On July 19, the PAGASA upgraded the disturbance to a tropical depression as it entered the Philippine Area of Responsibility, assigning it the local name Hanna. The JMA later recognized the system as a tropical depression at 03:00 UTC on the same day, with the JTWC doing the same at 09:00 UTC, designating it as 11W. On July 21 at 00:00 UTC, the JMA upgraded it to a tropical storm assigning it the name Lan. The JTWC also upgraded it to a tropical storm at 03:00 UTC. The system had deep flaring convection, however its low-level circulation was broad and elongated. On July 22, at 00:00 UTC, the JMA upgraded the system to a severe tropical storm. Lan started moving westwards, and as it gradually strengthened, Lan developed a formative eye on July 23, at 03:00 UTC. At 09:00 UTC, the JTWC declared Lan to have strengthened into a typhoon as it had deep convection and robust outflow. The JMA also followed suit and upgraded Lan to a typhoon at 12:00 UTC because of good upper-level outflow and higher sea surface temperatures; however, its central dense overcast was still obscure. On the next day at 03:00 UTC, Lan strengthened into a Category 2-equivalent typhoon as its central convection continued to deepen. The feeder bands became more compact and the eye of the typhoon became clearer and more defined. The JTWC assessed that it peaked as a Category 2-equivalent typhoon with maximum wind speeds of 95 kn at 03:00 UTC the same day. Because of dry air, the JTWC later downgraded Lan to a Category 1-equivalent typhoon at 03:00 UTC the next day despite the presence of warm sea surface temperatures and low wind shear. On July 26 at 21:00 UTC, Lan got further downgraded to a tropical storm by the JTWC, as its eyewall became fragmented and the deep convection was not continuous over the eye; it later re-intensified into a Category 1-equivalent typhoon again at 03:00 UTC the next day as it regained convective depths and it managed to maintain a ragged eye. At 09:00 UTC, PAGASA issued its final advisory as Typhoon Lan moved northwards and exited the PAR. On July 27, at 06:00 UTC, Lan peaked as a typhoon with maximum 10-minute sustained wind speeds of 80 kn and a minimum pressure of 950 hPa, according to the JMA. On the next day, the China Meteorological Administration (CMA) noted Lan to have made landfall in Putuo Island at around 04:30 UTC. After making landfall, the JTWC downgraded it to a tropical storm at 09:00 UTC as it eye structure began to degrade. JMA later downgraded to a severe tropical storm at 12:00 UTC, because of influence of land and involvement of dry air.

In Okinawa Prefecture, rough waves impacted coastal areas. Rains began to pound Minamidaitō and Kitadaitōjima on July 22. Winds up to 32.1 mph were recorded on Nanjō in the early hours of July 24, with 28.1 mph being recorded at Uruma and 26.9 mph being recorded at Naha. This was enough to down power lines, which affected 860 people in the main island of Okinawa and the villages of Iheya and Izena. In Mainland China, record-breaking rainfall was reported, which caused flooding in the province of Henan. These devastating floods brought the death toll of the 2023 Henan floods to 99. This was caused because of the moisture associated with a tropical wave and Lan, despite being far away. The CMA issued a blue warning over the Fujian coast and north Zhejiang. CMA later upgraded the warning to an orange warning as Lan moved closer to China. After making landfall, CMA downgraded its warning to a yellow warning as the threat of the typhoon lessened. In Taiwan, the Central Weather Bureau issued a heavy rainfall warning for Kaohsiung, Pingtung County and Hengchun Peninsula and a sea warning for the northern and eastern coasts of the country as Lan's periphery nears, however it was cancelled at 02:05 UTC (10:05 TST). In the Philippines, Lan strengthened the annual monsoon, causing heavy rainfall mainly in Luzon. Heavy rainfall and flooding have been reported in some areas. As the typhoon moved southwest towards the Philippine Sea, PAGASA raised a Signal No. 1 warning for the province of Batanes and the Babuyan Islands in preparation of strong winds and heavy rainfall. The warnings were later lifted as it exited the PAR.

Typhoon Saola
A tropical depression formed near Mariana Islands on July 25. By July 26, it intensified into a tropical storm, and was named Saola by the JMA. Tropical Storm Saola soon became a typhoon, and rapidly intensified to become a category 3-equivalent typhoon on July 28. Upwelling of cooler waters induced weakening thereafter; by August 2, Saola weakened below typhoon intensity. Saola continued moving, albeit slowly, towards Japan with little change in intensity. On August 3, Saola expanded into 950-miles (1,600 km) in diameter giant storm. Moderately conducive conditions were unable to aid Saola in strengthening, and it stayed the same intensity before landfall in Japan. On August 4, Saola emerged in the Sea of Japan and a few days later on August 6, Saola transitioned into an extratropical low.

The typhoon brought torrential rain to parts of Shikoku and Honshu, with accumulations peaking at 869.5 mm at Yanase in Kochi Prefecture. Wind gusts reached 151 km/h in Muroto. Rough seas produced by the storm killed two people while flooding killed one other. Fifty-five people were injured in various incidents. Damage in Japan amounted to be ¥2.177 billion (US$20.5 million).

Severe Tropical Storm Damrey (Ineng)
On August 3 of 18:00 UTC, the JMA noted that a low-pressure area had formed that was embedded in a large monsoonal circulation to the north of Palau. The system developed into a tropical depression at 00:00 UTC of the next day. At 09:00 UTC (17:00 PHT), the PAGASA issued its first bulletin for the first tropical depression and assigned it the name Ineng. The JMA also noted the persistence of another, nearby tropical depression to its northeast, later named Jenny. As it is embedded in the same monsoonal depression and due to its proximity, Jenny began to merge with Ineng, and therefore formed a rather broad and large circulation. This prompted the JMA to upgrade the overall system to a tropical storm, and was named Damrey. However at that time, the JTWC still considered the system as two separate disturbances and issued separate TCFAs later in the day for both depressions, albeit noting the possibility of merging. The JTWC later considered the entire system as merged with their first warning for Damrey. At midnight of August 8, the JMA upgraded it to a severe tropical storm, as it attained good cloud characteristics. At 12:10 UTC (20:10 PHT), Damrey made its first landfall near Fuga Island of Cagayan Province. At 05:00 PHT of August 10 (21:00 UTC of August 9), the PAGASA issued its final bulletin as its exited the PAR and continued towards Hainan. Between 03:00 and 09:00 UTC of August 10, Damrey had made landfall over the east coast of Hainan. By 18:00 UTC, the JMA downgraded it to a tropical storm, as it crossed the entire island and entered the Gulf of Tonkin, as its convection had rapidly weakened because of the rough terrain of the island. At 09:00 UTC of the next day, the JTWC issued its final warning followed by downgrading to a tropical depression, as its convection had diminished and the low-level circulation center had been weakened significantly because of the increasing vertical wind shear and dry air, despite not making landfall over northern Vietnam. The JMA issued its final warning after downgrading it to a tropical depression at 18:00 UTC.

As of August 15, the NDRRMC has confirmed a total of 43 deaths, along with 16 people still missing. Total estimated damages of both infrastructure and agriculture is topped to ₱6.39 billion (US$126.5 million). In Hong Kong, one person was killed and 21 people were injured.

Tropical Depression Jenny
On 00:00 UTC of August 5, the JMA began monitoring on a tropical depression that had developed to the north of Palau, that was embedded in the same monsoonal circulation as Tropical Depression Ineng. As the circulation moved inside the Philippine Area of Responsibility, the PAGASA began issuing advisories and assigned the local name Jenny to the depression. By the next day, the JMA stopped tracking the system after it began to merge with Ineng, which subsequently became Tropical Storm Damrey. The PAGASA issued its final bulletin on the system on August 7. The JTWC issued separate TCFAs for two invests in the monsoonal depression that contained Ineng and Jenny — Invests 97W and 98W, respectively. As the two merged, the JTWC cancelled the TCFA for Invest 97W and soon began issuing a single tropical cyclone warning for the overall system.

Typhoon Haikui
Early of August 11, the JTWC noted the formation of an area of convection located 752 nmi east-southeast of Guam. On the next day, the JMA recognized the same system as a low pressure area. At 06:00 UTC of August 13, the JTWC issued a TCFA as it developed a poorly defined center, and by midnight of August 13, the JMA upgraded the system to a tropical depression. The JTWC followed suit and designated it as 14W at 15:00 UTC the same day. Six hours later, the JTWC further upgraded it to a tropical storm. At midnight of the next day, the JMA followed suit and named it as Haikui. On 00:00 UTC of August 15, the JMA further upgraded it to a severe tropical storm. Fifteen hours later, the JTWC declared it a typhoon and upgraded it to a Category 1-equivalent status, as Haikui developed an eye according to microwave imagery. The JMA followed suit at 18:00 UTC. By 03:00 UTC the next day, it further intensified into a Category 2-equivalent typhoon as it briefly formed a ragged eye. Later that day, Haikui unexpectedly rapidly intensified to a Category 5-equivalent super typhoon due to jet interaction. It later reached peak intensity with 10-minute sustained winds of 195 km/h (120 mph) and a pressure of 910 mb. However, this peak was short-lived as strong wind shear, dry air, and cooler sea surface temperatures shredded the system apart and rapidly weakened to a Category 1-equivalent typhoon at 18:00 UTC. On August 18 at 06:35 UTC, JMA declared Haikui a remnant low.

Tropical Storm Kirogi (Kabayan)
On August 14, the JTWC noted an area of convection located approximately 495 nmi east of Davao, Philippines Later that day, the JTWC issued a TCFA as it developed sufficient convection and a fairly defined LLCC. However, the JTWC cancelled the TCFA as it crossed the Visayas region. Despite this, the PAGASA had already classified the system as a tropical depression and named it Kabayan, on August 15. Kabayan made its first landfall on Bucas Grande Island at 04:30 PHT (August 15, 20:00 UTC). It then made an additional seven landfalls: ones in Cagdianao in the Dinagat Islands, Liloan and Padre Burgos in Southern Leyte, Mahanay Island and Getafe in Bohol, San Fernando in Cebu, Guihulngan in Negros Oriental, and its last two landfalls at Iloc Island and El Nido, Palawan. At 14:30 UTC of August 16, the JTWC re-issued a TCFA for the system, as it moved over the South China Sea. At 06:00 UTC of August 17, the JMA recognized it as a tropical depression. At 11:00 PHT (03:00 UTC) of August 18, the PAGASA issued its final warning. At 09:00 UTC of the next day, the JTWC upgraded from a monsoonal depression to a tropical depression. It was designated as 15W. Satellite imagery found that the LLCC had become exposed but still had a defined warm core. The system's center was also ragged. At 18:00 UTC, the JMA upgraded it to a tropical storm and named it Kirogi. Nine hours later, the JTWC did the same as the convection developed a curved pattern. Kirogi continued its trajectory, and between 09:00 UTC and 15:00 UTC of August 20, it made its first landfall over the island of Hainan. After making landfall, it briefly intensified a bit before weakening to its original intensity at 21:00 UTC. At 09:00 UTC of the next day, it crossed the island completely and entered the Gulf of Tonkin. On August 22, at 09:00 UTC, the JTWC downgraded it to a tropical depression and issued its last warning, as it made landfall near Cat Bi International Airport and its convection became disorganized over land. The JMA also downgraded it to a tropical depression at 06:00 UTC the same day, but continued to monitor it. The JMA last noted at 18:00 UTC of August 22.

In its early stages of formation, the system passed through the central Philippines. As of August 19, the NDRRMC recorded three deaths and estimated agricultural damages were topped at ₱12.2 million (US$241,000).

Severe Tropical Storm Yun-yeung
A parade of tropical waves spawned in mid-August, in the western Pacific. One of those disturbances rapidly intensified into Tropical Depression 16W on the morning of August 19 at 0000 UTC (0900 JST) 190 nautical miles (350 kilometers) southwest of Marcus Island, Japan. It reached tropical storm strength the next day and was named Yun-yeung. It reached peak intensity late on August 21. Yun-yeung curved to the northwest and never threatened land. It tranistioned to an extratropical cyclone on August 24 at 00:00 UTC (09:00 JST), 735 nautical miles (1,285 km) east-southeast of Nakashibetsu, Hokkaidō, Japan. The remnants of the storm crossed the International Date Line on August 26 and dissipated soon after.

Typhoon Koinu (Liwayway)
Due to its proximity to the Philippines, PAGASA assigned it the name Liwayway and began issuing advisories on a disturbed area of tropical weather to the east of the islands on August 25. The JMA started to warn on the system on the same day. On August 26, it was classified as Tropical Depression 17W by the Joint Typhoon Warning Center. On August 27, it was upgraded to Tropical Storm Koinu. Koinu strengthened into a typhoon on August 30. Koinu made landfall at Wanning, in China's Hainan province at 20:00 UTC, August 31 (04:00 September 1 local time) with maximum sustained winds up to 180 km/h. This made Koinu the strongest typhoon to strike Hainan since Typhoon Marge in September 1973.

At least 16 people are believed to have died in China, and the entire province of Hainan suffered power outages. Koinu then went on to impact Vietnam before losing tropical characteristics while a tropical storm. The Joint Typhoon Warning Center ceased advisories with the final one at 09:00 UTC September 3, with the system 90 nmi south-southwest of Hanoi, Vietnam.

Typhoon Bolaven
The Joint Typhoon Warning Center identified an area of disturbed weather northeast of Chuuk on August 26. The disturbance drifted to the north over the next few days, gradually increasing in organization. The JTWC issued a Tropical Cyclone Formation Alert on the disturbance on August 29, and both the JTWC and JMA declared the system a tropical depression early on August 30. The JMA upgraded it to Tropical Storm Bolaven later that morning as it moved erratically through the open Pacific Ocean, and the JTWC soon followed suit. Bolaven was upgraded to a severe tropical storm by the JMA on August 31, and the JTWC designated it a typhoon later that day. The JMA officially upgraded Bolaven to typhoon status early on September 1. Bolaven was upgraded briefly to a super typhoon by the JTWC from September 2 to 3. On September 6, the JTWC reported that Bolaven was becoming extratropical as it continued to weaken, and issued its final warning the next day. The JMA downgraded Bolaven to a severe tropical storm on September 5. It started to recurve near Chichi-jima, and never affected major land areas. It became extratropical near the western Aleutians on September 7. Its extratropical remnants crossed the basin on September 9.

Severe Tropical Storm Sanba
Late on September 3, a disturbance formed west of Taiwan. Early on August 31, the JMA upgraded it to a tropical depression that had developed about 60 km to the north of Taipei, Taiwan. It was then later, designated as 19W by the JTWC as it moved towards the east of Taiwan. Favorable conditions of strengthening to a tropical storm as it heads to wards warm waters. On September 5, Tropical Depression 19W rapidly intensified into Tropical Storm Sanba. Sanba entered the southern islands of Japan as it intensified. On September 6, Sanba created a small unbalanced eye as it rapidly races towards Japan. On September 7, moderate wind shear occurred as the JMA upgraded Sanba to a severe tropical storm as it enters the southern coast of Japan killing 3. Strong vertical wind shear made Sanba weaken to a depression. The JMA reported on September 9, that Sanba had degenerated into an extratropical low, before it dissipated during the next day.

Typhoon Jelawat (Marilyn)
On 06:00 UTC of September 6, the JMA briefly tracked a weak tropical depression to the east of Iwo To, Japan. The JMA re-upgraded the system to a tropical depression two days later. On September 9, the JTWC designated the system 20W and it was located approximately 262 nmi southwest of Iwo-To. On the same day, the JMA and the JTWC upgraded the system to a tropical storm, with the JMA assigning it the name Jelawat. The storm then reached typhoon status on September 12. Jelawat rapidly intensified into a violent typhoon, according to the JTWC's thirteenth bulletin. Jelawat then entered the PAGASA's Philippine Area of Responsibility at 09:40 UTC on September 13, and was given the name Marilyn, however, it quickly left the PAR, just over four hours later, at 14:00 UTC on the same day. A system pressure of 911 hPa (mbar) was then recorded. When it made landfall in southern Japan, the typhoon was downgraded to Category 4-equivalent status upon reaching Kyushu Islands. Upon directly impacting the country, it was downgraded again to Category 2-equivalent status. On its way to northeast Japan post-landfall, the cyclone was downgraded to a tropical storm by the JTWC. The JMA also followed suit and downgraded it to a severe tropical storm. In its twenty-ninth bulletin, the JTWC reported that Jelawat was weakening as it moved over land in Japan and would be downgraded to an extratropical cyclone.

Before the cyclone hit the country, the JMA issued a special warning that Jelawat could cause severe damage, and at least 4 million people have been advised to leave their homes. Exceptionally high volumes of precipitation were recorded and resulted in flooding in streets, destruction of building walls. and destroyed power poles. At least 2 people died and another 70 people were injured. More than 200,000 people were left without electricity. In South Korea, the winds and rain caused by the typhoon also caused inconvenience. One person was injured, more than 700 people were evacuated from their homes, fallen trees were reported, and some locations in the south-east of the country were left without electricity.

Tropical Depression Nimfa
On September 15, the JTWC started to monitor a persisting area of convection with a poorly-defined circulation at approximately 645 nmi to the east of Manila, Philippines. Under a favorable environment of warm sea surface temperatures, low to moderate wind shear, and strong poleward outflow, the system continued to organize before PAGASA upgraded it as a tropical depression, naming it as Nimfa, late on September 16. The JMA subsequently followed suit by the next day. Later that same day, the JTWC issued a TCFA on Nimfa, noting that the storm's center was tucked beneath the southeast side of an intense but disorganized convection. However, the storm's convective structure got detached from the main center due to a TUTT cell to the northeast of it, which made the storm weaken as it moved northwestwards, prompting the JMA to downgrade Nimfa into a low-pressure area on September 20. The PAGASA subsequently followed suit late on the same day, and JTWC cancelled their TCFA by September 21.

Though short-lived, Nimfa killed two people in Cagayan, Philippines. The Provincial Disaster Risk Reduction Management Office (PDDRMO) in Cagayan estimated infrastructure and agricultural damage at ₱533 million (US$9.16 million) and 33,432 individuals were impacted by Nimfa.

Typhoon Ewiniar (Onyok)
On September 26, a disturbance developed into tropical depression near the Philippines, according to the JMA. The JTWC designated this disturbance as Invest 99W and issued a bulletin noting that the low pressure system could have reasonable intensification due to low wind shear and warmer water. Hours later, the JTWC upgraded the system into a tropical depression, designating it as 21W. The PAGASA then followed suit on 00:00 UTC of September 27, and the tropical depression was assigned the name Onyok. A few hours later, the system reached tropical storm intensity and the JMA assigned it the name Ewiniar. The PAGASA raised TCWS #1 at 21:00 UTC on September 28, with TCWS #3 being raised a day later as the storm rapidly intensified into a typhoon. On September 29, Ewiniar entered the Philippine area of responsibility and reached typhoon intensity. Ewiniar then underwent explosive intensification, during which, according to the JTWC, Ewiniar 's 1-minute sustained winds increased by 165 km/h. PAGASA raised signal No. 4 on the same day, informing that the north of Luzon could be severely impacted by the cyclone. At 00:00 UTC on September 30, the JTWC classified Onyok as a Category 5-equivalent super typhoon. PAGASA then followed and upgraded Ewiniar to a super typhoon. At 5:30 p.m. Philippine Standard Time, according to the PAGASA, Ewiniar struck Burdeos, Polillo Islands, Quezon Province. At 8:20pm PHT, Ewiniar struck Dingalan in the province of Aurora as a typhoon according to PAGASA. The terrain of the Sierra Madre mountain range weakened Ewiniar as it passed through Central Luzon.

Ewiniar then slightly re-intensified in the West Philippine Sea, leaving the PAGASA's area of responsibility on October 1.

Tropical Storm Maliksi
On October 11, a disturbance turned into a tropical depression according to the JMA. The JTWC reported that the low pressure encountered favorable environments for intensification by warm waters and low wind shear. The next day, the JTWC designated the system as 22W as it was upgraded into a tropical depression. On October 13, the cyclone was upgraded to a tropical storm according to the JTWC's sixth bulletin. The storm was named Maliksi by the JMA. When it made landfall in southern Japan, it was downgraded to a tropical depression according to the seventh JTWC bulletin.

A 10 to 12 centimeters total hourly, total 30 to 42 centimeters in twelve hours precipitation hit in Hamamatsu, Shizuoka City and other areas of Shizuoka Prefecture. A landslide hit Ōigawa Railway in Kawane, two transmission towers collapsed in Aoi-ku, Shizuoka, and 119,200 customers were affected by power outages in Shizuoka Prefecture, according to Heita Kawakatsu, Governor of Shizuoka. According to the Japan Fire and Disaster Management Agency official report, Maliksi killed three people and injured six others.

Typhoon Gaemi (Perla)
On October 11, the JMA started to monitor a tropical depression, that developed within an area of low to moderate vertical windshear, about 670 km to the east of Hagåtña on the island of Guam. Tropical Depression 23W, formed 696 nautical miles south of Iwo Jima, Japan on October 13. It strengthened into tropical storm named Gaemi, then continued to intensify into a severe tropical storm and later a typhoon. Wipha then rapidly intensified into a Category 4 typhoon on October 15. During the morning of October 16, Gaemi entered the Philippine area of responsibility, and PAGASA promptly named it Perla as it created an eyewall replacement cycle becoming a Category 4 typhoon later that day. Early on October 17, Gaemi rapidly weakened as it approached cooler waters near Japan. Late on October 19, Gaemi transitioned into an extratropical storm. The remnants of Gaemi continued to accelerate towards the northeast, and were located southeast of the Kamchatka Peninsula on October 20. Soon afterwards, Wipha turned to the east, and crossed the International Date Line on October 21.

Typhoon Prapiroon (Quiel)
On October 17, the JMA began to monitor a weak tropical depression that had developed in the Philippine Sea and had been designated as Invest 95W by the JTWC. The agency said in a TCFA bulletin that because it was in warmer waters and low shear, there was scope for broader intensification. The prediction was confirmed, and a few hours later, it was classified as a tropical depression, being called 24W. The following day, the storm entered the PAGASA's area of responsibility and was called Quiel, but it did not directly threaten the Philippines and left the PAGASA’s area of responsibility a few hours later. Subsequently, the cyclone gained strength and reached a "tropical storm" according to the second JTWC bulletin. The JMA named the system Prapiroon. Two days later, the JTWC and JMA classified it as a Category 1 typhoon, The intensification did not last long and Prapiroon was downgraded to a tropical storm. The JTWC released a final bulletin in which Prapiroon had been downgraded to an extratropical cyclone, late on October 20. However, the cyclone intensified into a subtropical storm according to the JTWC's special bulletin. On October 21, it weakened into a subtropical depression.

Tropical Depression 25W
A disturbance that formed after crossing the Visayas region and Palawan on late March developed into a low-pressure area southeast of Da Nang, Vietnam. It then developed into a tropical depression, the first one of the season, at 18:00 UTC on October 20. At 21:00 UTC the same day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) for the system. On the next day, the agency upgraded to a tropical depression, assigning it the designation 25W. Shortly after, they issued their final advisory on the system after it made landfall in the southeastern part of Vietnam on October 22.

In Vietnam, floods caused by the depression have killed six people, left one missing and eight injured. Flooding also caused two houses to collapse, 50 houses to lose their roofs, 229 boats to sink, and 2,592 rafts to be damaged.

Severe Tropical Storm Maria (Ramon)
On October 29, PAGASA started to monitor a tropical depression that had developed about 420 km to the east of Hinatuan, Surigao del Sur. The JMA, however, tracked the depression on October 30. The JTWC would shortly follow suit, designating it as 26W. Over the rest of the day, the depression was gradually organizing under favorable conditions, before the PAGASA reported that tropical depression Ramon had made landfall over Siargao Island around 12:00 UTC (8:00 p.m. PST) of the same day. The JTWC would also follow suit shortly. On 12:00 UTC of October 31, the JMA reported that Ramon became a tropical storm while traversing the Visayan Sea, naming it as Maria. Around 21:00 UTC of the same day, the PAGASA reported that Ramon became a tropical storm while nearing Panay Island. Maria would emerge into the Mindoro Strait while making its second landfall and traverse on the Calamian Islands. Shortly after emerging into the South China Sea on November 1, JMA reported that Maria briefly reached its peak intensity of 95 km/h (50 knots) and a pressure of 992 hPa. The JTWC would follow suit, upgrading Maria to a category 1 typhoon, reaching its peak intensity of 135 km/h (75 knots) and a pressure of 967 hPa, while weakening to a tropical storm at 12:00 UTC the same day. Around 03:00 UTC (11:00 a.m PST) of November 1, PAGASA reported that Maria slightly intensified while the storm is re-intensifying in the South China Sea. On the next day, the JTWC reported that Maria has regained its category 1 status, and had made its secondary peak intensity with 145 km/h (80 knots) and a pressure of 963 hPa. Afterwards, Maria rapidly weakened below typhoon intensity on 12:00 UTC the same day, below tropical storm intensity at 18:00 UTC, and both agencies discontinued advisories on 00:00 UTC of November 3. The PAGASA, however, discontinued advisories for Ramon 3 hours later, around 11 a.m. PST.

A total of 2,980 families were affected during Maria's passing, and only 712 families evacuated to their designated evacuation centers and 67 families were served outside. A total of 46 municipalities and 9 cities on the regions Mimaropa, 6, 7, 8, 10, NIR and CAR suspended their classes during the storm, a total of 32 flights were cancelled, a total of 6 transmission lines were affected in Visayas, 2 landslides were reported on Sogod, Southern Leyte and Baybay, Leyte, 8 flooding incidents were reported around Oriental Mindoro, Romblon, and Negros Occidental. A total of 16 houses were destroyed during the storm (totally or partially), 40 hectares of palay to tillering stage and 15 hectares in ripening stage were damaged on some parts of Iloilo, and a total of ₱1,500,000 (US$28,788) as reported damages to infrastructure. In response, the DSWD provided a total of ₱24,9049.57 ($47,79.58 USD) to the affected families on Surigao del Norte and Surigao del Sur.

Other systems
On May 24, the JMA tracked a weak tropical depression a few hundred miles off the Japanese coast, but it dissipated on two days later due to high wind shear, and cool sea surface temperatures.

The JMA began tracking a tropical depression that had formed to the east of Hainan on July 9. The system moved westward towards Vietnam and was last noted three days later.

On July 17, a tropical depression formed over the open Pacific at 18:00 UTC. By July 19, at 05:30 UTC, the JTWC issued a TCFA for the system as it had an exposed low-level circulation with persistent disorganized convection. The agency canceled the alert on the next day as it had little remaining convection and it had moved over cooler waters.

On July 21, at 00:00 UTC, the JMA noted a tropical depression near 29°N, 152°W, which was moving northwards slowly.

On August 23, at 00:00 UTC, the JMA noted a tropical depression near 28°N, 142°W, which was moving northwestward slowly.

The JMA started to monitor a weak tropical depression that formed just west of the International Date Line on September 15. The system persisted until early on September 18.

Storm names
Within the Northwest Pacific Ocean, 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. 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, should they be judged to have 10-minute sustained windspeeds of 65 km/h. PAGASA names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it. The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in.

International names
A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h. 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. Retired names, if any, will be announced by the WMO in 2023; though replacement names will be announced in 2025. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.

Philippines
This season, PAGASA will use its own naming scheme, that will either develop within or move into their self-defined area of responsibility. The names were taken from a list of names, that was last used during 2019 and are scheduled to be used again during 2027. All of the names are the same except Tamaraw and Ugong which replaced the names Tisoy, Ursula after they were retired Auxiliary list
