The September 2009 Vietnam tropical depression was a weak tropical depression that caused deadly flooding throughout central Vietnam in early September. Forming out of an area of low pressure on September 3, the depression hardly intensified as it meandered off the coast of Vietnam. Initially situated in a favorable environment, convective banding features began to develop and shower and thunderstorm activity formed near the center. On September 4, the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert; however, a sudden increase in wind shear caused the system to rapidly become disorganized, leading to the cancellation of the alert the next day. The system continued to slowly track off the coast of Vietnam, nearly dissipating on September 5, before becoming better organized. However, the depression remained weak, with the JTWC reporting on September 7 that the depression had dissipated, though the Japan Meteorological Agency (JMA) continued to issue advisories until the depression dissipated during September 9.
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 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.
Tropical Depression 18W was a tropical depression that impacted Vietnam, Laos and Thailand during mid September 2013. The system was first noted as a tropical depression on September 16, 2013, while it was located within the South China Sea to the south east of Hanoi in Vietnam. Over the next two days the system gradually developed further, before it was reported by the Vietnamese National Centre for Hydro Meteorological Forecasting that the system had developed into their eighth tropical storm of 2013. However, other meteorological agencies did not report that the system had developed into a tropical storm.
Tropical Storm Bebinca, known in the Philippines as Tropical Depression Fabian, was a weak tropical cyclone that brought minor damage in China and Vietnam, causing a death and an economic loss of about US$13 million. The sixth depression and fifth named storm of the season. Bebinca originated as a low-pressure area south of Hong Kong. As the disturbance is moving westward, favorable conditions allow the system to organize into a tropical depression. On June 21, the depression was upgraded into a tropical storm despite the wind shear, which generated by a subtropical ridge.
Tropical Storm Mangkhut, known in the Philippines as Tropical Depression Kiko, was a storm that made landfall in Vietnam during August 7 and 8, 2013. Mangkhut, a replacement name for Durian, which is a Thai fruit for mangosteen. The 10th named storm of this season. Shortly after Tropical Storm Jebi made landfall over northern Vietnam, another area of low pressure was recognized northeast of Puerto Princesa, Palawan, the system is also favorable for any intensification. After being named Kiko by PAGASA, the storm consolidated further, resulting in being named Mangkhut as it intensified into a tropical storm. Mangkhut moved north-northwest before making landfall over northern Vietnam. The system later dissipated at Laos on August 8.
Severe Tropical Storm Mirinae was a tropical cyclone of moderate intensity that struck Hainan Island, China and Northern Vietnam in late July 2016. The third named storm of the annual typhoon season, Mirinae formed on July 25, 2016 as a tropical depression west of Luzon, Philippines. On July 26, it moved west-northwestwards, and it had intensified into a tropical storm before making landfall on Hainan Island, China. After passing over Hainan, it intensified into a severe tropical storm and made landfall over the Red River Delta in Northern Vietnam late on July 27, and dissipated the next day.
Tropical Storm Rai was a weak and short-lived tropical cyclone which affected Indochina in September 2016. Formed from a tropical disturbance on September 11, the system developed into a tropical storm and reached its peak intensity on September 12, before making landfall in Vietnam and affecting Laos, Thailand and Cambodia. In Vietnam total damage reached US$73.96 million.
Severe Tropical Storm Aere, known in the Philippines as Tropical Storm Julian, was a long-lived tropical cyclone that struck Central Vietnam in October 2016. The nineteenth named storm of the annual typhoon season, Aere formed on October 4, 2016 as a tropical depression to the east of Luzon, Philippines shortly after the JMA had started tracking Songda. On the next day, the system had become a tropical storm and it moved into South China Sea. During October 7, it intensified into a severe tropical storm and reached peak intensity with 10-minute winds of 110 km/h (70 mph). Shortly thereafter, due to remaining in almost the same area for hours, Aere began to weaken to a tropical storm, and on October 10, it weakened to a tropical depression, before weakening to a low-pressure area late on October 11. On October 13, Aere re-generated into a tropical depression and it made landfall in Huế, Vietnam late that day. The system moved towards Laos and Thailand before it fully dissipated on October 14.
Tropical Storm Sonca was a weak tropical cyclone that impacted Indochina during the end of July 2017.
Typhoon Doksuri, known in the Philippines as Tropical Storm Maring, was a strong Category 2 typhoon that mostly impacted the Philippines and Vietnam during mid-September 2017. Forming as the nineteenth named storm of the season, Doksuri developed as a weak tropical depression over to the east of Visayas on September 10.
The October 2017 Vietnam tropical depression, also known officially by its designation as Tropical Depression 23W, was a weak but deadly system that brought torrential rainfall and extreme flooding over northern and central Vietnam in October 2017. The depression formed on October 7, located to the northwest of Luzon, Philippines. The system moved in a general westward direction as it steadily intensified. Despite being forecast to strengthen into a tropical storm, 23W failed to reach this intensity, due to lack of organization as it made landfall in Hà Tĩnh Province on October 10.
Typhoon Damrey, known in the Philippines as Severe Tropical Storm Ramil, was a strong tropical cyclone that affected the Philippines and Vietnam during early November 2017. Damrey first originated as a tropical depression over the Philippine archipelago of Visayas on October 31. Emerging into the South China Sea a few days later, the system strengthened into the second deadliest and twenty-third named storm of the 2017 Pacific typhoon season. Rapidly intensifying, Damrey became the season's tenth typhoon on November 3, reaching its peak intensity as a Category 2 on the same day. Damrey made landfall over Khánh Hoà, Vietnam on November 4 and began to rapidly weaken, fully dissipating on November 5.
The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
Tropical Storm Pabuk, also referred to as Cyclonic Storm Pabuk, was a weak storm that struck the Malay Peninsula in January 2019. It was also the earliest-forming storm in both the Northwestern Pacific Ocean and North Indian Ocean basins on record. Forming on the last day of 2018, Pabuk persisted into 2019, spanning two calendar years, and crossed into the North Indian Ocean basin several days later. The first tropical cyclone and named storm of the 2019 Pacific typhoon and North Indian Ocean cyclone seasons, Pabuk originated as a tropical disturbance in the South China Sea on December 28, 2018, which organized into a tropical depression on December 31. A day later, on January 1, 2019, the system intensified into a tropical storm and was named Pabuk. Pabuk made landfall in Thailand on January 4, emerging into the Bay of Bengal in the North Indian Ocean basin shortly afterward. Pabuk weakened after it entered the North Indian Ocean, eventually degenerating into a remnant low on January 7, before dissipating on the next day.
Tropical Storm Noul, also known in the Philippines as Tropical Storm Leon, was a weak, but deadly tropical cyclone that impacted central Vietnam, which had been affected by Tropical Storm Sinlaku more than one month earlier. Noul originated from a tropical system in the Philippine Sea in September 15. The system was upgraded into a tropical depression later that same day by JMA, with JTWC and PAGASA following suit in 15:00 UTC, with PAGASA assigning the local name Leon to the developing tropical cyclone. As Leon was leaving the area of responsibility, Leon intensified into a tropical storm and was assigned the international name Noul by JMA. Noul would make landfall between Quảng Trị and Thừa Thiên-Huế provinces in September 18 before degenerating into a remnant low over Thailand later that day.
The 2020 Central Vietnam floods were a series of floods in Central Vietnam, which also affected some areas in Cambodia and Laos in October and early November 2020. The floods focused heavily in several provinces including Thừa Thiên Huế, Hà Tĩnh, Quảng Bình, Quảng Trị, and Quảng Ngãi. The floods were mainly caused by the seasonal monsoon, though enhanced by numerous tropical cyclones.
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.
Tropical Storm Linfa was a weak, short-lived but deadly and destructive tropical cyclone that was the twelfth wettest tropical cyclone on record and the second of nine tropical cyclones in a row to strike Vietnam in 2020, a little under a month after the less damaging Tropical Storm Noul. The fifteenth named storm of the 2020 Pacific typhoon season, Linfa originated from a tropical depression which formed just to the west of the Philippines on October 6. After passing through the island nation, the storm emerged into the South China Sea and slowly gained strength, earning the name Linfa on October 10 on approach to Vietnam. On the next day, Linfa had reached peak strength and made landfall in Vietnam, marking the beginning of a devastating series of floods in the country and worsening the already active monsoon season. Linfa quickly dissipated as it moved inland, but associated thunderstorms continued for several days.
Tropical Storm Koguma was a weak tropical cyclone that made landfall in Vietnam, causing minor damage. The fourth named storm of the 2021 Pacific typhoon season, the system was first noted as an area of persistent convection on the South China Sea on June 10, with the JTWC assessing the system in its first advisory as a monsoon depression. Tracking west-northwestward, marginally conductive environmental conditions in the area allowed slight intensification while drifting towards Hainan Island. On the next day, the JMA upgraded the system to a tropical depression as it passed to the south of the territory before the agency upgraded the system to a tropical storm on June 12, being assigned the name Koguma. The JTWC; however still treated the system as a tropical depression until 12:00 UTC that day. It continued to move northwest over the warm waters of the Gulf of Tonkin, eventually making landfall in Vietnam over Thanh Hóa by the end of the same day, rapidly weakening afterward.
