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.
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.
Severe Tropical Storm Jebi, known in the Philippines as Tropical Storm Jolina, was a tropical cyclone that caused loss of life and moderate damage across Vietnam and South China in July 2013. At least six people were killed in Vietnam. The most extensive losses took place in Quảng Ninh Province where 320 homes and 200 hectares of crops were damaged. In China, losses were listed at CNY490 million.
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.
Tropical Storm Vamco was a weak tropical cyclone which affected Indochina in mid-September 2015. Formed from a tropical disturbance on September 13, the system developed into a tropical storm and reached its peak intensity on September 14. Vamco made landfall in Vietnam and affected Laos, Thailand and Cambodia. The storm caused flooding in these countries and damages amounted to US$14.1 million. Fifteen people died in the floods.
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.
Severe Tropical Storm Talas was a tropical cyclone that impacted Vietnam during mid July 2017. Talas was first tracked as a tropical disturbance over in the South China Sea on July 13, and was upgraded to a tropical depression during the next day. The depression intensified into the fourth named storm of the 2017 Pacific typhoon season during July 15. Before making landfall in Vietnam, Talas reached its peak intensity as a severe tropical storm during July 16. Talas weakened to an area of low pressure on July 17 inland.
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.
Tropical Storm Son-Tinh, known in the Philippines as Tropical Storm Henry, was a weak but very deadly tropical cyclone that devastated Vietnam and Laos in July 2018. Son-Tinh originated from an area of low pressure over the Philippine Sea on July 15, 2018. Moving quickly westwards, Son-Tinh strengthened to the ninth tropical storm of the annual typhoon season on July 17. Intensifying only slightly while crossing the South China Sea, Son-Tinh made its first landfall over Hainan Island on July 18. After emerging into the Gulf of Tonkin, Son-Tinh restrengthened before making its second landfall as a tropical storm in Northern Vietnam on July 19. Once inland, Son-Tinh weakened into a low pressure area as it slowed and made a clockwise loop. The remnants of Son-Tinh then emerged back over water and regenerated into a tropical depression late on July 21.
Tropical Storm Sinlaku was a weak tropical cyclone that impacted Vietnam, Thailand and Laos in August 2020. Beginning as a tropical depression on July 31 in the South China Sea, Sinlaku was the fifth storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow west-northwest course, strengthening into a tropical storm the following day despite its monsoonal structure. The storm subsequently made landfall in Vietnam as a broad but weak tropical storm. Persistent land interaction weakened Sinlaku, leading to its dissipation on August 3.
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.
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.
Tropical Storm Dianmu was a weak tropical cyclone that caused considerable damage over parts of Mainland Southeast Asia during late-September 2021. The fifteenth named storm of the 2021 Pacific typhoon season, Dianmu originated from an area of low-pressure situated in the South China Sea on September 21. Being first monitored by the Joint Typhoon Warning Center, the system rapidly consolidated to a tropical depression on September 22 as it continued to approach Vietnam before strengthening further to a weak tropical storm, with the Japan Meteorological Agency naming it as "Dianmu". Little intensification occurred before it made landfall on the country with winds of 35 knots. It then rapidly weakened over land and dissipated on September 24 as a tropical cyclone.
Vietnam is a southeast Asian country, and is the easternmost country of mainland Southeast Asia. It borders the East Sea, hence, seeing the increased likeliness of tropical cyclones. Tropical cyclones in this area are considered to be part of the Northwest Pacific basin, and therefore, storms here are considered as typhoons.
