Severe Tropical Storm Maliksi,known in the Philippines as Severe Tropical Storm Domeng,was a tropical cyclone in June 2018 that brought rainfall to the Philippines and Japan. It caused 2 deaths and prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The fifth named storm and 4th tropical cyclone in the Philippine Area of Responsibility (PAR), [1] it was first noted as an area of convection in the South of Palau on May 31.
On May 31 at 06:00 UTC, the Joint Typhoon Warning Center (JTWC) began monitoring an area of convection approximately 95 nautical miles (175 km; 110 mi) south of Palau. The system was disorganized, with convection being located to the east of a broad and elongated low-level circulation. It was located in favorable conditions for development and sea surface temperatures in the area ranged from 29–30 °C (84–86 °F), though the JTWC assessed its development potential in the next day as low. [2] The system's low-level circulation began consolidating, and on June 2 at 00:30 UTC, the JTWC upgraded its development potential in the next day to medium. [3] On June 3 at 18:00 UTC, the Japan Meteorological Agency (JMA) assessed that a tropical depression had formed over the Philippine Sea. [4] [lower-alpha 1] On the next day at 03:00 UTC, the PAGASA gave the depression the local name Domeng as it was located 675 kilometres (420 mi) east of Guiuan. [6] The depression absorbed an invest as convection covered the low-level circulation, and on 14:00 UTC the same day, the JTWC issued a Tropical Cyclone Formation Alert as it was located approximately 225 nautical miles (415 km; 260 mi) northwest of Palau. [7]
The depression began to exhibit signs of anticyclonic outflow as it was steered northward by a mid-level subtropical high-pressure area, [8] and on June 7 at 12:00 UTC, the JTWC upgraded the system to a tropical depression, assigning it the designation 06W. [9] 6 hours later at 18:00 UTC, both the JMA and the JTWC upgraded the depression to a tropical storm, with the JMA giving it the name Maliksi; [4] [9] the system's circulation remained broad. [10] Maliksi passed by the western edge of the high-pressure area and turned northeast, [11] and on June 9 at 06:00 UTC, the JMA upgraded it to a severe tropical storm. [4] At 21:00 UTC, Maliksi exited the PAR, with the PAGASA issuing its final warning on the system. [12] On June 10 at 00:00 UTC, Maliksi peaked in intensity, with maximum sustained winds of 110 km/h (70 mph) and a minimum barometric pressure of 970 hPa (29 inHg) as it was located southeast of Okinawa. [4] [lower-alpha 2] The JTWC assessed Maliksi to have peaked at the same time, also estimating the same windspeed in the 1-minute sustained standard. [9] [lower-alpha 3] Maliksi began slowly accelerating to the northeast, developing a ragged eye as it became exposed to strong westerlies. [14] After reaching peak intensity, convection around the center began to decrease, [15] with the low-level circulation beginning to elongate. [16] Maliksi began extratropical transition as it was located over an unfavorable environment, [17] and on June 11 at 18:00 UTC, the JMA assessed that Maliksi completed its transition into an extratropical cyclone, [4] with its low-level circulation being displaced from its upper-level circulation; [18] the JTWC estimated extratropical transition began 6 hours earlier. [9] Maliksi's remnants dissipated east of Honshu on June 13. [4]
The PAGASA warned residents of possible floods and landslides, advising fishermen not to go to sea. [19] Beginning June 5, classes were suspended in parts of Luzon and the province of Biliran. 73 people were evacuated in Calabarzon. [20]
Maliksi enhanced the southwest monsoon in the Philippines, bringing monsoonal rains over Luzon and Visayas. [19] A bridge received damage in San Fernando, Romblon, and on Tablas Island, power went out for a day due to fallen trees impacting power lines. Patients in the University of Santo Tomas Hospital were evacuated after floodwaters entered the building. [21] Trees were uprooted in Quezon City and Coron, Palawan, and in Calintaan, a temporary bridge was washed out by a river. 16 houses were damaged in San Fernando, Pampanga, six of which were completely damaged. A SkyJet Airlines flight on route from Metro Manila overshot the runway at Francisco B. Reyes Airport, injuring 2 of 86 on board, including the first officer. In Batangas, 8 municipalities lost power on June 9 at 3:00 PM local time, before being restored 6 hours later. [22] In Metro Manila, overnight rains flooded at least 43 barangays, [23] with several streets becoming impassable. [24] Floods in parts of Quezon City's 4th congressional district reached 5 feet (150 cm). [20] On June 9 at 11:00 PM local time, due to the heavy rainfall in Metro Manila, the PAGASA issued a red rainfall advisory for the area, along with other warnings for the regions of Calabarzon and Central Luzon. [25] Two people from Palawan and Albay drowned after jumping or falling into the ocean. 72 passengers and 2 vessels were stranded in Legazpi, Albay and Rapu-Rapu, with other ports in Oriental Mindoro suspending their operations. [23] A total of 132 people were affected in San Fernando, Pampanga and Santa Cruz, Zambales. [20]
Due to the effects of Maliksi, the PAGASA declared the beginning of the rainy season due to widespread rainfall in PAGASA weather stations. [26] Those affected in San Fernando, Pampanga received ₱41 thousand (US$770) worth of aid. [20]
As Maliksi approached Okinawa, its meteorological observatory cautioned of high waves around the island. [27] The outer road at Kitadaitōjima was closed on June 9, with all fishing vessels being brought to port. [28] Sea and air travel near the Daitō Islands were interrupted on June 10. [29] On the same day, the Okinawa Meteorological Observatory issued a storm warning for the Daitō Islands, [30] with Kitadaitōjima receiving an evacuation advisory. [31]
On the island of Hachijō-jima, 287.5 millimetres (11.32 in) of precipitation was recorded, [32] and on Kitadaitōjima, a gust of 28.3 metres per second (100 km/h; 65 mph) was recorded. [33] In Chichibu, Saitama, there were rains around noon as the storm was approaching the Kantō Region, though winds were not strong. [34] Some sugarcane crop in Kitadaitōjima was damaged due to strong winds. [35]
The 2010 Pacific typhoon season, with 14 named storms, was the least active Pacific typhoon season on record. Seven of them strengthened into typhoons while one reached super typhoon intensity. All of the 14 named storms developed west of 150°E.
The 2017 Pacific typhoon season was a below-average season in terms of accumulated cyclone energy and the number of typhoons and super typhoons, and the first since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir–Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.
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 Rumbia, known in the Philippines as Tropical Storm Gorio, was a tropical cyclone that brought widespread flooding in areas of the Philippines and China late June and early July 2013. The sixth internationally named storm of the season, Rumbia formed from a broad area of low pressure situated in the southern Philippine Sea on June 27. Steadily organizing, the initial tropical depression moved towards the northwest as the result of a nearby subtropical ridge. On June 28, the disturbance strengthened to tropical storm strength, and subsequently made its first landfall on Eastern Samar in the Philippines early the following day. Rumbia spent roughly a day moving across the archipelago before emerging into the South China Sea. Over open waters, Rumbia resumed strengthening, and reached its peak intensity with winds of 95 km/h (50 mph) on July 1, ranking it as a severe tropical storm. The tropical cyclone weakened slightly before moving ashore the Leizhou Peninsula late that day. Due to land interaction, Rumbia quickly weakened into a low pressure area on July 2 and eventually dissipated soon afterwards.
Most of the tropical cyclones of the 2013 Pacific typhoon season formed between May and November of that year. The scope of this article is the Pacific Ocean north of the equator, between 100°E and the International Date Line. Tropical storms which form in the Western Pacific basin are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions forming in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility, but these names are not in common use outside the Philippines.
This timeline documents all of the events of the 2014 Pacific typhoon season. Most of the tropical cyclones forming 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. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
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 Neoguri, known in the Philippines as Typhoon Florita, was a large and powerful tropical cyclone which struck Japan in 2014. The eighth named storm and the second typhoon of the annual typhoon season, Neoguri developed into a tropical storm on July 3 and then a typhoon on July 4. It rapidly deepened on July 5, reaching peak intensity late on July 6. Neoguri began to decay on July 7 and passed through Okinawa on July 8 and then making landfall over Kyushu as a severe tropical storm late on July 9. After Neoguri passed through the southern coast of Honshū on July 10, it became extratropical on July 11.
Typhoon Phanfone, known in the Philippines as Typhoon Neneng, was a powerful tropical cyclone which affected Japan in early October 2014. It was the eighteenth named storm and the eighth typhoon of the 2014 Pacific typhoon season. Phanfone started as a large area of convection well west of the International Date Line. The system was well organized and classified as Tropical Depression 18W on September 29. At the same day, it gained the name Phanfone due to very favorable conditions and intense thunderstorms rich with convection surrounding the storm's center. Phanfone would later go rapid intensification on October 1 due to warm sea-surface temperatures and very favorable environments. JTWC upgraded Phanfone to a Category 4 typhoon but weakened later back to Category 3 due to its eye replacing the old one and undergoing a minor eyewall replacement cycle.
Typhoon Vongfong, known in the Philippines as Super Typhoon Ompong, was the most intense tropical cyclone worldwide in 2014, and struck Japan as a large tropical system. It also indirectly affected the Philippines and Taiwan. Vongfong was the nineteenth named storm and the ninth typhoon of the 2014 Pacific typhoon season. Estimates assess damage from Vongfong to have been over US$160 million, mainly for striking mainland Japan. At least 9 people were killed along the path of the typhoon in those countries.
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.
Typhoon Noul, known in the Philippines as Super Typhoon Dodong, was a relatively small but powerful tropical cyclone that affected several areas but caused minor damage. The sixth named storm and third typhoon of the annual typhoon season, Noul formed as a tropical depression over the eastern Caroline Islands on May 2, 2015. It moved generally to the west and west-northwest, gradually intensifying into a tropical storm and later typhoon. On May 9, Noul began rapid deepening as it developed a well-defined eye. Early the next day, the Japan Meteorological Agency (JMA) estimated peak 10 minute sustained winds of 205 km/h (125 mph), while the American-based Joint Typhoon Warning Center (JTWC) estimated peak 1 minute winds of 260 km/h (160 mph), equivalent to Category 5 on the Saffir–Simpson hurricane wind scale. Noul struck northeastern Luzon in the Philippines at that intensity and greatly weakened. After passing east of Taiwan, the typhoon accelerated to the northeast and weakened due to unfavorable conditions. On May 12, Noul became extratropical south of Japan, and the remnants continued to the northeast for several days, dissipating on May 16.
Tropical Storm Kujira was a tropical cyclone that prompted the PAGASA to declare the beginning of the rainy season in the Philippines. The ninth tropical depression, 8th named storm, and first storm to make landfall on China in the 2015 Pacific typhoon season, it formed as a tropical depression south of the Paracel Islands on June 19.
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.
Severe Tropical Storm Ampil, known in the Philippines as Severe Tropical Storm Inday, was a tropical cyclone that caused moderate damage in the Ryukyu Islands and East and Northeast China in late July 2018. The tenth named storm of the annual typhoon season, Ampil developed into a tropical depression east of Luzon on July 17. The system gradually strengthened over the following days amid a marginally favorable environment and became a severe tropical storm late on July 19 as it moved northwest. Maintaining its strength, Ampil passed over Okinawa Island from July 20 to 21. Thereafter, Ampil weakened slightly while crossing the East China Sea, before making landfall in Shanghai, China, on July 22. The system weakened slowly over land and degraded to a tropical depression on July 23. The system turned eastwards as it continued weakening over land, diminishing to a remnant low on July 25 and dissipating fully a day later over the Russian Far East.
Severe Tropical Storm Usagi, known in the Philippines as Tropical Storm Samuel, was a tropical cyclone that affected the Philippines and Southern Vietnam in late November 2018, causing severe damage around the Visayas region and Ho Chi Minh City. The storm formed from a disturbance in the Central Pacific basin on November 3, but did not develop into a tropical storm until almost three weeks later, on November 13. Usagi underwent rapid intensification and peaked in intensity before making its final landfall on Vũng Tàu, Bà Rịa–Vũng Tàu province as a weakening tropical storm on November 25. While never considered as a typhoon by the Japan Meteorological Agency (JMA), the Joint Typhoon Warning Center (JTWC) assessed its intensity to be equivalent to Category 2 status on the Saffir–Simpson scale. Usagi caused one death and ₱52.2 million (US$992,000) in damages in the Philippines, most of which came from agriculture. Usagi caused 3 deaths and ₫925 billion in damages in 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.
