Tropical Depression 01W During May 25, Tropical Depression 01W developed over the northern South China Sea, about to the south of Hong Kong, China. The system subsequently moved north-westwards and slightly developed further, before it made landfall near
Yangjiang in
Guangdong, China during the next day. The system was located within an environment that was thought to be favourable for further development, with low vertical wind shear and a fair outflow. However, the depression's broad low level circulation centre was moving north-westwards quickly, which meant that the circulation's southern edge could not close off and was exposed. However, the JMA continued to monitor the system as a tropical depression throughout June 27, as it emerged into an unfavourable environment for further development in the South China Sea. The depression subsequently made landfall on China's
Guangdong Province, before it was last noted during June 28, as it dissipated over land.
Typhoon Nepartak (Butchoy) On July 2, a tropical depression formed to the southeast of
Yap State. The following day, the depression became a tropical storm, receiving the name
Nepartak. Early on July 5, Nepartak started to undergo
rapid intensification, reaching typhoon strength. During the course of July 6, Nepartak reached its peak intensity with 10-minute sustained winds of and a minimum barometric pressure of 900 mbar. Nepartak started weakening during the next day, before making landfall in
Taitung City on July 8. Nepartak weakened to a tropical storm as it made its second landfall in
Shishi, Fujian. Nepartak rapidly deteriorated over land and fully dissipated on July 10. Two people drowned on July 7 after being washed out to sea by strong winds in
Taiwan. A total of seven major highways were damaged in Taiwan, too. At least 10 people were killed and 11 others were reported missing across Fujian and
Jiangxi. At least 3,144 homes were destroyed and of crops were damaged; total economic losses reached
¥2.2 billion (US$320 million). Overall, Nepartak killed a total of 86 people, mostly from
Fujian Province, and caused a total of
¥9.99 billion (US$1.49 billion) of damage.
Tropical Depression 03W During July 14, a tropical disturbance developed about to the west-northwest of Guam. At this time atmospheric convection surrounding the system was flaring, over the system's weak but developing low level circulation center. After the system had consolidated further, it was classified as Tropical Depression 03W by the JTWC during July 17. However, the system weakened during that day as it moved polewards, along the western edge of the subtropical ridge of high pressure, into an area of increasing vertical wind shear. However, over the next couple of days the system continued to move northwards and impacted the
Ryukyu Islands, before it was last noted by the JMA during July 20.
Tropical Storm Lupit During July 21, a subtropical disturbance developed at the tailend of a mid-latitude trough of low pressure, about to the east of
Iwo-To. Over the next day, deep atmospheric convection developed over the system's elongated low level circulation center, before it was classified as a tropical depression by the JMA during July 22. Over the next day, as the storm moved north-northeastwards around a subtropical ridge of high pressure, its structure improved as it developed a warm core and consolidated. The hybrid system was subsequently classified as Tropical Storm 04W by the JTWC during July 23, before the JMA named it Lupit later that day. Lupit subsequently became extratropical during July 24, before it dissipated during July 26, as it moved into the
Sea of Okhotsk. The next day, it was named Mirinae after it became a tropical storm. The system reached its peak intensity as a severe tropical storm on July 27, with 10-minute sustained winds of . Mirinae subsequently weakened gradually over northern Vietnam, before it dissipated to the north of Hanoi. while another station in Ba Lạt (
Thái Bình) recorded wind gusts of . In Hainan, economic losses caused by the storm reached 300 million yuan (US$45 million). By July 29, the storm had left five people dead and five others missing in Vietnam. Severe damage to infrastructure was reported in Northern Vietnam, with damage to power lines causing blackouts and power cuts in some areas. Mirinae also sank 12 boats, destroyed the roofs of 1,425 houses and uprooted about 5,000 trees. Damages in Vietnam amounted to ₫7.229 trillion ($323.9 million). Over the next day as the system moved north-northwestwards under the influence of a subtropical ridge of high pressure, deep convection started wrapping into the system's low level circulation center. During that day PAGASA assigned the local name Carina. On July 31, Nida made
landfall over the area between
Baggao and
Gattaran of the
Cagayan province in the
Philippines at 13:20
PST (05:20
UTC) as a severe tropical storm. At 03:35
CST on August 2 (19:35 UTC on August 1), Nida made landfall over
Dapeng Peninsula of
Shenzhen,
Guangdong, China as a severe tropical storm. While it lashes the Northeastern part of the Philippines, the provinces of
Isabela,
Cagayan,
Quirino Province,
Abra,
Mt. Province,
Benguet,
Kalinga Province, and
Ifugao Province reported that some of their major roads was not passable due to landslides. Despite the local governments of the said areas reported that there are no casualties, they still reported that some of them are injured during the typhoon. Damages in
Ilocos Norte were estimated at
₱19.38 million (US$411,000).
Severe Tropical Storm Omais During August 2, the JMA started to monitor a tropical depression that had developed within a favourable environment for further development, about to the northeast of
Hagåtña,
Guam. The system had a broad and weak low level circulation centre, which had atmospheric convection flaring around the system's outer edge. A high-pressure system kept Omais to the east of Japan producing hot and steamy conditions across Japan approximately about 1000 people were taken to hospital due to heat stroke as the
heat index climbed well into the 40s. On August 9, Omais transitioned to an extratropical cyclone as it moved over cooler waters of the northwestern Pacific Ocean, Omais fully dissipated on August 10.
Tropical Storm Conson On August 7, the JMA started to monitor a tropical depression that had developed about to the west of Wake Island. Over the next day the system gradually developed further as it moved south-westwards, before the JTWC classified it as Tropical Depression 08W during August 8. Later that day, the JMA upgraded 08W to a tropical storm, naming it
Conson. Despite some moderate wind shear, Conson slowly intensified and later reached severe tropical storm strength on August 10. The JTWC later stated that deep convection was forming near the center of Conson, however shortly thereafter, convection became disorganized. By August 11, convection once re-intensified again, however its LLCC became exposed, causing the JTWC to lower its intensity to lower-end of tropical storm strength. The JMA also downgraded Conson to a tropical storm. During the next day, satellite image showed that the convective structure of Conson was beginning to deteriorate as it started to interact with drier air, suppressing convection. The center of Conson became much broader and exposed early on August 13. While moving northwestward, Conson became better defined than before, however its convection was more shallow as it started to interact will cooler sea-surface temperatures and drier air. By August 14, the JTWC issued their final warning on Conson as it started to undergo its extratropical transition with a result of a strong wind shear and the interaction of the mid-latitude baroclinic zone. The JMA tracked Conson until it fully transitioned into an extratropical cyclone on August 15 and made landfall near
Nemuro Peninsula. After meandering eastwards, the JTWC designated the system as
09W, while the JMA immediately upgraded 09W to a tropical storm and assigned it the name
Chanthu on August 13. The JTWC followed suit early on August 14. With an improving LLCC, Chanthu rapidly developed into a severe tropical storm from the JMA, as it was later located over in an area of favorable environments of strengthening. Despite a high chance of strengthening and a well-defined LLCC, Chanthu stopped generating convection as the JMA downgraded it to a tropical storm. Later that day, flaring convection was associated with its LLCC as it was beginning its extratropical transition while interacting with mid-latitude flow. Therefore, early on August 17, Chanthu once again reached severe tropical storm strength as it attained its peak intensity with a minimal pressure of 980
millibars (28.94 inHg), while east of the Japanese archipelago of
Honshu. Shortly thereafter, the JTWC issued its final warning on Chanthu. The JMA issued its final warning a few hours later as it made
landfall over
Cape Erimo of
Hokkaido, Japan, at peak intensity. Agricultural damage in Japan were at
¥9.49 billion (US$94.7 million).
Tropical Storm Dianmu On August 15, a tropical depression developed about to the southeast of Hong Kong. During the course of August 17, enhanced satellite imagery showed that Dianmu was rapidly organizing with deep flaring convection surrounding its LLCC. Dianmu made landfall in
Haiphong and
Thái Bình Province in northern
Vietnam. While overland, the system gradually weakened into a tropical depression, before it degenerated into an area of low pressure during August 20 while over Myanmar.
Typhoon Mindulle A tropical depression formed northwest of
Guam on August 17. On August 19, the system became a tropical storm and was named
Mindulle early on August 19. However, an
upper-level low to the north and the predecessor of
Tropical Storm Kompasu to the northeast were stifling the development of poleward
outflow. Moving on the eastern edge of a relatively high-latitude monsoon gyre and being steered by the southern extension of the
subtropical ridge anchored east of Japan, the intensification of Mindulle was limited on August 20, owing to modest dry air entrainment resulting in flaring convection near and surrounding the LLCC. Although Mindulle became a severe tropical storm when it was approximately northwest of
Chichi-jima at around 15:00
JST (06:00
UTC) on August 21, outflow from
Tropical Storm Lionrock to the west was inhibiting further development, as the distance between their centers was only about at that time. With warm
sea surface temperatures of between , good equatorward and poleward outflow channels, as well as low vertical
wind shear, Mindulle became a
typhoon at around 03:00 JST on August 22 (18:00 UTC on August 21), when the center was located about east of
Hachijō-jima. At around 12:30 JST (03:30 UTC), Mindulle made landfall over the area near
Tateyama, Chiba.
Typhoon Lionrock (Dindo) The system that was to become Typhoon Lionrock was first noted as a hybrid disturbance on August 15, while it was located about to the west of
Wake Island. It developed into a tropical depression about northwest of
Wake Island on August 16. At this time the disturbance had a broad and poorly organized low level circulation centre, which had some shallow bands of
atmospheric convection wrapping loosely around it. From late August 20 to early August 22, the system had at least somewhat an interaction with Mindulle, taking an erratic and slow path for a bit. Restrengthening begun again quickly, with the system already starting to develop an eye in mid-August 23. In the middle of the 24th of August the system reached an initial peak as a Category 3-equivalent storm. Lionrock entered the
Philippine Area of Responsibility on August 25, 2016, and
PAGASA assigned
Dindo as the local name, while Lionrock had begun an eyewall replacement cycle early that day, weakening to a Category 2-equivalent storm. After two days, early on August 26, it finally completed the eyewall replacement cycle, but slow restrengthening occurred. Another two days passed until it reached its full peak as a Category 4-equivalent storm, which rapid weakening ensued after. On August 29, Lionrock turned towards the northwest due to a high-pressure system located east of Japan, putting it on an towards the northeastern region of the country. Lionrock made
landfall near
Ōfunato, a city in
Iwate Prefecture, Japan. This made Lionrock the first tropical cyclone to make landfall over the Pacific coast of the
Tōhoku region of Japan since the Japan Meteorological Agency began record-keeping in 1951.
Tropical Storm Kompasu On August 18, the JMA started to monitor a tropical depression that had developed, about to the northeast of Guam. The JTWC started issuing advisories by the next day as it was immediately classified as a tropical storm and the identifier of
13W. The JMA followed suit early on August 20, and was named
Kompasu. Both agencies reported that Kompasu had reached its peak strength as a minimal tropical storm with a minimum barometric pressure of about 994 mbar. Later that day, deep convection of Kompasu had rapidly decreased as it was located in marginally favorable environments with low wind shear and sea-surface temperatures of about 26 degrees Celsius. On August 21, the JTWC downgraded Kompasu to a tropical depression and issued their final bulletin on the system. The JMA did the same and issued its final advisory on Kompasu as it transitioned into an extratropical system.
Tropical Depression 14W During August 23, Tropical Depression 14W developed about to the east of
Andersen Air Force Base,
Guam. Moving northward on the next day, the LLCC of 14W became exposed with a deteriorating convective signature. Flaring deep convection became disorganized into a weakly defined center due to strong northerly wind shear; the JTWC assessed 14W's winds only at 25 knots. Due to a rapidly decaying LLCC with minor bursts of convection, both the JMA and the JTWC issued its final warning on 14W later that same day.
Typhoon Namtheun (Enteng) A low-pressure area developed into a tropical depression southeast of
Taiwan early on August 31. Later that day, the JTWC began issuing advisories on the system, assigning the designation of
15W. Early the next day, 15W had intensified into a tropical storm by both agencies, with the JMA prompting the name
Namtheun. The PAGASA however started issuing advisories on Namtheun and considered it as a tropical depression and gave the local name
Enteng. Despite the overall structure of the storm being described to be "midget" with a very small but compact LLCC, Namtheun had begun a phase of
rapid intensification and a pinhole eye developed; therefore, the JTWC upgraded Namtheun to a Category 1 typhoon. The JMA, though, upgraded Namtheun only to a severe tropical storm at that time. Later that day, PAGASA had declared that the storm had exited its area of responsibility as a severe tropical storm. By September 2, rapid intensification ensued as it was reported that Namtheun was located over a region of warm sea surface temperatures of 30 degrees Celsius with high ocean heat content, therefore prompting the JMA to classify it to a typhoon. Namtheun developed a pinhole eye across and reached its peak strength as a Category 3 typhoon with 1-minute sustained winds of ; the JMA though declared its 10-minute peak strength early on September 3 with a minimum barometric pressure of 955 millibars. By that time, Namtheun was depicted with significantly weakened structure and a dissipation of its eye, therefore the JTWC downgraded Namtheun rapidly to a strong Category 1. On September 4, Namtheun had weakened to a tropical storm due to diminishing convection, caused by high southwesterly wind shear. After making landfall over in
Nagasaki,
Kyushu, both the JMA and JTWC issued its final advisory as a tropical depression early on September 5.
Tropical Storm Malou On September 5, the JMA started to monitor a tropical depression, that had developed over the Japanese prefecture of Okinawa. The depression was located within a favourable environment for further development, with very warm sea surface temperatures and low vertical wind shear. Over the next day the system moved north-eastwards towards the Japanese Mainland, before it was classified as a tropical storm and named Malou by the JMA during September 6. However, the JTWC classified Malou as a hybrid system, with both subtropical and tropical characteristics. They also noted that the convective development around the system's low level circulation centre was being hindered, as the subtropical westerlies were located over the system. During September 7, the system started to accelerate northwards, before the JMA issued their final advisory on the system as Malou became an extratropical cyclone.
Typhoon Meranti (Ferdie) On September 8, a tropical depression formed in a region of low
wind shear, steered by
ridges to the north and southwest, with warm
water temperatures and
outflow from the south. The system reached tropical storm strength by 06:00 UTC on September 10, receiving the name Meranti. Rainbands and a
central dense overcast continued to evolve as the wind shear decreased. By early on September 12, Meranti reached typhoon status. A small
eye across developed within the spiraling thunderstorms, and Meranti started
rapidly intensifying. Meranti quickly attained estimated 1-minute sustained winds of , equivalent to Category 5 on the
Saffir–Simpson scale. Meranti gradually reached its peak intensity on September 13 while passing through the
Luzon Strait. The JMA estimated peak 10-minute sustained winds of and a minimum
barometric pressure of 890
hPa (
mbar; 26.28
inHg), while the JTWC estimated peak 1-minute sustained winds of . Based on the JMA pressure estimate, Meranti was among the
most intense tropical cyclones. The JTWC wind estimate made Meranti the strongest tropical cyclone worldwide in 2016, surpassing
Cyclone Winston, which had winds of when it struck
Fiji in February. Late on September 13, the storm made landfall on the island of
Itbayat in the Philippine province of
Batanes while near its peak intensity. At around 03:05
CST on September 15 (19:05 UTC on September 14), Meranti made landfall over
Xiang'an District,
Xiamen in
Fujian, China with measured 2-minute sustained winds of , making it the strongest typhoon to ever make landfall in China's
Fujian Province.
Tropical Depression 17W During September 8, the JTWC started to monitor a tropical disturbance that had developed about to the west of
Iwo To. Moving northward in a few days, the JTWC assessed that the system had strengthened into Tropical Depression 17W. Despite its LLCC remaining small, satellite imagery showed that 17W produced persistent convection and some spiral banding. Later, drier air surrounded the depression as it was now firmly embedded with the west-southwesterly flow ahead of the mid-latitude frontal zone. The JTWC issued their final advisory on 17W on September 12, as the system was rapidly deteriorating due to vertical wind shear, and weakened into a remnant low. In the JMA's post-analysis, 17W was recognized as a tropical depression, and the system was first noted on September 10.
Tropical Storm Rai On September 11, a tropical depression formed within an unfavourable environment for further development, about to the northeast of
Ho Chi Minh City,
Vietnam. Satellite imagery then showed that the LLCC of 19W was broad and defined with some deep convective banding. Its LLCC became exposed, though its deep convection remained in place. Although the JMA declared that 19W had strengthened into a tropical storm, the JTWC deemed the system to not have reached tropical storm intensity. Rai made landfall over
Central Vietnam, about southeast of the city of
Da Nang. Rai degraded to a tropical depression six hours later. Heavy rains in Central Vietnam and Northern Thailand caused flooding and the bursting of the Bung River 2 hydroelectricity plant in Quảng Nam province of Vietnam, which released 28 million cubic meters of water and washed away 2 workers. Four ships were sunk along central Vietnam's coastline and 2 others were left stranded, while 5 houses were completely destroyed and 275 others had their roofs torn off. Most of the damage occurred in
Nghệ An Province due to flooding, amounting to about
₫748 billion (US$33.6 million). In total, Rai caused 12 deaths and damages amounting to ₫825 billion (US$37 million).
Typhoon Malakas (Gener) On September 11, a tropical depression formed approximately south of
Hagåtña, Guam. On becoming a tropical storm, it was named
Malakas. By September 13, Malakas had improved in its organization and became a severe tropical storm thereafter. At the same time, Malakas had entered the Philippine area of Responsibility, with PAGASA assigning the local name
Gener. Despite hindrance by the outflow of nearby Typhoon Meranti, Malakas intensified into a typhoon. On September 16, Malakas
rapidly intensified into a Category 4 typhoon. Malakas reached its peak intensity with 1-minute sustained winds of , 10-minute sustained winds of , and a pressure of by the following day. Shortly thereafter, its eye became cloud-filled and ragged, signalling the onset of weakening. After weakening to a Category 2 typhoon, Malakas reintensified to a Category 3 typhoon by September 19. Malakas then resumed weakening due to land interaction with Japan. By the following day, Malakas weakened below typhoon intensity, and became extratropical. At around 00:00
JST on September 20 (15:00 UTC on September 19), Malakas made landfall over the
Ōsumi Peninsula in Japan. It subsequently crossed
Cape Muroto at around 11:00 JST (02:00 UTC) and made landfall over
Tanabe at around 13:30 JST (04:30 UTC).
Typhoon Megi (Helen) Megi originated as a tropical depression about east-southeast of
Guam on September 21. The depression became a tropical storm by on September 23. On the following day, Megi intensified to a severe tropical storm. On developing an eye, Megi reached typhoon intensity. Shortly thereafter, Megi entered PAGASA's area of responsibility, and the local name
Helen was assigned. After a day of slight intensification, Megi started to undergo an
eyewall replacement cycle. From then on, Megi rapidly intensified as it neared the coast of Taiwan. Megi reached peak intensity as a Category 3 typhoon over Taiwan with 1-minute sustained winds of , 10-minute sustained winds of , and a minimum barometric pressure of 945 mbar late on September 26. Early on September 27, Megi made landfall over
Hualien City, weakening due to land interaction. Megi made landfall over in
Hui'an County of
Quanzhou the next day. Megi continued deteriorating as it moved inland. In
Taiwan, government officials announced that 814 school campuses across Taiwan were damaged, at an estimated cost of NT$161 million (US$4.17 million). In all, 8 people were killed in Taiwan, and total economic losses were counted to be NT$3.36 billion (US$106.9 million). Meanwhile, 44 people were killed in mainland China, and total damages were amounted to
CNY9.7 billion (US$1.45 billion).
Typhoon Chaba (Igme) On September 24, a weak tropical depression had developed approximately east-northeast of
Guam. The system reached tropical storm status and was assigned the name
Chaba late the next day. By September 30, Chaba had intensified into a severe tropical storm after deep convection had evolved into a banding feature, under very favorable conditions. During October 1, Chaba entered the
Philippine area of responsibility, with PAGASA giving the local name
Igme, as it started to move in a northwestward direction. Chaba became a typhoon after its organization and structure vastly improved. During the next day, Chaba began
explosive intensification, reaching Category 5 super typhoon intensity with a sharp wide eye. Chaba reached its peak intensity with 10-minute sustained winds of , while 1-minute sustained winds were at , and the minimum central pressure was 905 mbar. Thereafter, Chaba began to weaken as its core became asymmetric, due to strong wind shear. As it neared the coast of
Busan,
South Korea, Chaba transitioned into an extratropical cyclone. The storm left widespread damage across the southern regions of South Korea, killing at least 7 and leaving 4 others missing. Transportation was disrupted, with hundreds of flights canceled, while more than 200,000 households lost electricity. Chaba was the strongest typhoon to strike the country since
Typhoon Sanba in 2012.
Typhoon Songda A tropical disturbance entered the basin from the Central Pacific late on October 3 and on the following day, became a tropical depression approximately east-southeast of
Wake Island. After moving westward for several days, 23W intensified into a tropical storm, with the JMA giving the name
Songda. By October 9, an eye feature became apparent in microwave imagery, and Songda reached severe tropical storm intensity. Six hours later, Songda intensified into a typhoon. Songda started to undergo rapid deepening, while forming a ragged eye. Songda eventually reached its peak intensity as a Category 4 super typhoon, despite 25-30 kt vertical wind shear, with 10-minute sustained winds of and a minimum pressure of 925 mbar. Shortly thereafter, Songda rapidly weakened as the wind shear increased further, and its eye became cloud-filled. The JTWC issued its final advisory, classifying Songda as a rapidly-weakening Category 3-equivalent typhoon. The storm was embedded within the deep mid-latitude westerlies and located over waters cooler than . The JMA downgraded Songda to a severe tropical storm in its final advisory on October 13, and Songda subsequently transitioned into an extratropical cyclone. The extratropical remnant of Songda went on to affect the west coast of North America with heavy rain and winds.
Severe Tropical Storm Aere (Julian) Shortly after Songda's formation, another tropical depression developed well east to the
Babuyan Group of Islands. Later that day, PAGASA named the system
Julian. Despite Julian's disorganised structure, conditions were favourable for development, with light to moderate wind shear and very warm
sea surface temperatures. After a significant increase of convection, the system became a tropical storm, receiving the name
Aere. Aere became a severe tropical storm the following day. Shortly thereafter, Aere reached itspeak intensity with 10-minute winds of , just shy of typhoon strength. Upwelling induced weakening, and Aere weakened to a tropical storm. By October 10, Aere's LLCC became exposed due to southwesterly wind shear, and Aere degenerated to a tropical depression. The JMA tracked its remnants as it moved southwestward until it weakened to a low-pressure area late on October 11. On October 13, the well-marked low-pressure area of Aere re-generated into a tropical depression, and was tracked by the JMA until it fully dissipated on October 14. Most of the damage was reported mainly in Vietnam, especially in the central region, where estimated damages for transport works were at 130 billion
₫ (US$5.83 million). A total of 25 houses were destroyed while 949 were damaged. In agriculture, 3.14 ha of rice and 11.5 ha of crops were damaged. In total, flooding by the storm caused
₫ 4.6 trillion (US$209 million) of damage. When 24W entered their area of responsibility, PAGASA assigned it the local name
Karen. By October 13, images depicted a broad LLCC; sea surface temperatures were high, at . Hours later, the system became a tropical storm, with the JMA naming it as
Sarika. Sarika continued organizing and reached severe tropical storm intensity. Several hours later, Sarika started to form an eye feature as it became a typhoon. The storm eventually reached its peak intensity as a Category 4 typhoon with 1-minute sustained winds of and a minimum barometric pressure of 935 mbar. Early on October 16, Sarika made landfall over in
Baler, Aurora. Dramatic weakening occurred as Sarika traversed the islands. After moving westward rapidly for two days, Sarika weakened to a severe tropical storm as it made landfall over in
Hainan. Sarika continued weakening as it made its final landfall over the border of
Vietnam and China, and dissipated later that day. Nearly 13,000 homes were damaged or destroyed, and more than 200,000 people were displaced. Agricultural damage in the Philippines was severe, totaling
₱3.63 billion (
US$ million).
Typhoon Haima (Lawin) During October 14, the JMA and JTWC reported that a tropical depression had developed about within the Caroline Islands to the south of Guam. During that day the depressions low level circulation center rapidly consolidated, while bands of atmospheric convection built and wrapped into the center. At this point of time, Haima was located in a very favorable environment with very high ocean heat content, very low wind shear and warm SSTs. Three hours later, Haima intensified into a severe tropical storm. Super Typhoon Haima (Lawin) intensified further. PAGASA used the term "super typhoon" on Haima for the first time since it was introduced in May 2015 due to
Typhoon Haiyan's ravage during 2013. PAGASA also raised Signal #5 in the provinces of
Cagayan and
Isabela, which made it a hazardous storm. Due to land interaction, Typhoon Haima weakened into a Category 4 storm and made landfall in
Peñablanca, Cagayan. Typhoon Haima weakened after landfall in the Philippines and landed in Hong Kong as a weakened Category 1 storm, in which Signal no. 8 was raised. By October 22, Haima became extratropical and dissipated on October 26. Total damages in the Philippines were at
₱3.74 billion (US$77.6 million).
Typhoon Meari On October 31, the JMA started to track a tropical depression about south of
Guam. Late on November 2, organization had increased as the JTWC upgraded the system to a tropical depression with the identifier of
26W. The JMA, however, had upgraded 26W to a tropical storm, giving the name
Meari early on the next day. With a rapidly consolidating LLCC, the JTWC followed suit of upgrading to a tropical storm. By November 4, now moving northward, feeder bands were covering its very broad and compact LLCC and therefore Meari intensified into a severe tropical storm. Hours later, deep convective banding with a
central dense overcast (CDO) seen from satellite imagery prompted the JTWC and the JMA to upgrade Meari to a typhoon. On the next day, organization ensued with deep convection wrapping into its center and its CDO feature becoming more symmetric. Meari intensified into a Category 2 typhoon. During the course of November 6, Meari reached peak intensity only as a Category 2 with 10-minute sustained winds of and a minimum barometric pressure of 955 mbar. Later that day, Meari started to move northeastward rapidly with a strong poleward outflow as it started to interact with high vertical wind shear. The JTWC downgraded Meari to a Category 1. On November 7, the JTWC issued its final advisory on Meari due to the fact that its convective structure had become frontal, therefore it had already transitioned into an extratropical cyclone. The JMA followed suit three hours later.
Tropical Depression On November 2, a tropical depression formed west of
Sabah,
Malaysia. On November 5, it made landfall in southern Vietnam, and moved westwards until it dissipated on November 6. The depression exacerbated the torrential rains and heavy flooding that had impacted central and southern Vietnam since mid October, damaging more than 20,000 homes. A total of 15 people were killed and total damage reached ₫1.073 trillion (US$48.1 million) in Vietnam from November 1, though a total of 35 have been killed since the flooding from October.
Tropical Storm Ma-on On November 8, the JMA started to track a tropical depression that had formed several nautical miles to the east of the
Mariana Islands. Later that day, the JTWC had started initiating advisories giving it the designation
27W. During the next day, the JMA upgraded 27W to a tropical storm, naming it
Ma-on, due to deep curved convection despite the system's LLCC being exposed. The JTWC followed suit, upgrading it to a tropical storm after the system became more symmetrical with deep convection over in an area of low wind shear. Later that day, Ma-on reached its maximum intensity with 10-minute sustained winds of and a minimum pressure of 1002 mbar. Despite additional strengthening being forecast, its LLCC became exposed as favorable conditions started to deteriorate. Both agencies downgraded Ma-on to a tropical depression and issued their final advisories, although, the JMA tracked Ma-on until November 13.
Tropical Depression 28W During November 9, the JMA reported that a tropical depression had developed, about to the east-northeast of
Kwajalein Atoll in the
Marshall Islands. Over the next couple of days, the system moved westwards through the
Marshall Islands, where it gradually consolidated further within a favourable environment for further development. During November 11, the JTWC initiated advisories and designated the system as Tropical Depression 28W, after atmospheric convection had started to wrap into the weekly defined low level circulation centre. The system subsequently degenerated into a tropical wave, before it was last noted by both warning centers during November 12.
Severe Tropical Storm Tokage (Marce) During November 23, PAGASA started to monitor a tropical depression that had developed about to the east of
Hinatuan,
Surigao del Sur. The
JMA, however, tracked the depression on November 24. The
JTWC would shortly follow suit, designating it as "29W". Over the rest of the day, the depression was gradually organizing under favorable conditions, before the
PAGASA reported that Tropical Depression "Marce" 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. Tokage 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 26, JMA reported that Tokage briefly reached its peak intensity of and a pressure of 992 hpa. On the next day, the JTWC reported that Tokage has regained its category 1 status, and had made its secondary peak intensity with and a pressure of 963 hPa. A total of 2,980 families were affected during Tokage'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

Typhoon Nock-ten (Nina) Nock-ten was first noted as a tropical depression on December 21, and quickly organized into a tropical storm. The system reached severe tropical storm intensity the following day, and then typhoon intensity the day after. Around this time, a well-defined eye formed, and the storm began rapidly intensifying. Nock-ten reached its peak intensity as a Category 5-equivalent super typhoon with 1-minute sustained winds of on December 25, becoming the strongest tropical cyclone recorded on Christmas Day anywhere in the world since at least 1960 in terms of 1-minute sustained winds. and the typhoon made its first landfall over
Catanduanes as a Category 4-equivalent super typhoon with 1-minute sustained winds of . where strong vertical wind shear associated with a cold surge event led to continued weakening, with the low-level circulation center becoming exposed. The JMA issued its final advisory on the system late on December 27, and the JTWC followed suit early on December 28.
Other systems • On June 22, the JMA started to monitor a broad tropical depression that had developed about to the southwest of
Manila in the
Philippines. The system was located within a favourable environment for further development, but was not expected to significantly develop any further, as an upper-level low was expected to move over the system. However, the system's remnants were tracked until they made landfall on central Vietnam on June 27. • The JMA upgraded a low-pressure area east of
Taiwan to a tropical depression on August 6. The system made landfall over eastern China on August 9. • On August 10, the JMA reported that a tropical depression had developed, about to the southeast of
Ishigaki Island. Over the next day the system moved north-westwards, within a marginal environment for further development, before it passed over
northern Taiwan and moved into the
East China Sea. The system subsequently continued moved westwards, before it was last noted as it made landfall on
southern China later that day. • During August 12, a tropical depression developed near the coast of Taiwan, about to the southeast of Taipei. The system subsequently made landfall on the island, before it was last noted during the next day as it dissipated over Taiwan. • A tropical depression briefly appeared over the
Gulf of Tonkin early on August 16. • On August 23, a tropical depression developed over the South China Sea. • Another tropical depression briefly formed northeast of the
Mariana Islands on August 24. • A tropical depression formed north of
Wake Island early on August 30, and it became extratropical on the next day. • On September 10, the JMA had briefly monitored a tropical depression to the east of
Okinawa. The system moved in a westward direction until dissipating several hours later on the same day. • On November 1, the JMA started to track a tropical depression about east of
Andersen Air Force Base,
Guam. Later that same day, the JMA started issuing advisories on the depression whilst the JTWC had issued a Tropical Cyclone Formation Alert, though they canceled it early on November 2. The system moved northward until the JMA issued its final advisory as it interacted with the outer rainbands of the nearby Typhoon Meari and became extratropical on November 5. • During December 10, the JMA started to monitor a tropical depression that had developed about to the southeast of Ho-Chi-Minh City in Southern Vietnam. Over the next couple of days, the system moved slowly westwards without developing any further, before it made landfall on and dissipated over Southern Vietnam during December 13. The depression had caused torrential rains and heavy flooding since mid December in Central and Southern Vietnam, where at least 24 people were killed and total damages had reached to at least ₫1.21 trillion (US$53.4 million) in Vietnam. • On December 27, the JMA briefly monitored on a tropical depression located near
Chuuk, which dissipated later on the same day. ==Storm names==
