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 HàTĩnh Province on October 10.
During October 6, the United States Joint Typhoon Warning Center (JTWC) started to monitor a tropical disturbance, that had developed about 1,010 km (630 mi) to the east of Manila in the Philippines. [1] The system had a broad low level circulation centre, while atmospheric convection associated with the system was displaced to the northeast of the centre. [1] The system was also located within a favourable environment for further slow development, with low to moderate vertical windshear and very warm sea surface temperatures of 30–32 °C (86–90 °F). [1] Over the next couple of days, the disturbance organised slightly, with atmospheric convection to the south of the disturbance improving as it moved westwards. [2] [3] During October 7, the Japan Meteorological Agency (JMA) reported that the disturbance had developed into a tropical depression, before the system passed over the Philippine island of Luzon. [1] [4]
By 10:00 UTC of October 8, the JTWC had issued a Tropical Cyclone Formation Alert, [5] while the JMA had determined that the system had winds of 55 km/h (35 mph). [6] Several hours later, the JTWC began issuing advisories and upgraded the system to a tropical depression, giving the designation of 23W. [7] The JMA followed suit and began issuing advisories three hours later on October 9. [8]

Despite being a weak system, 23W caused severe damage in many provinces across northern Vietnam. Rainfall of 100–150 mm (3.9–5.9 in) was recorded in the northern and central parts of the country, especially in the provinces of Nghệ An and Hà Tĩnh. Many hydroelectric dams and lakes had to be discharged and the Ministry of Industry and Trade established a working group to ensure the safety of 31 hydroelectric lakes. [21] Heavy rainfall contributed to flash flooding, with five people swept away and an additional five injured in the district of Trạm Tấu, Yên Bái Province. Rescuers saved 28 people from the "danger zone". [22] About 740 houses were flooded, with 30 ending up fully destroyed. The authorities mobilized some 2,200 people, including the military, police, Youth Union and civil defense offices, accompanied by a variety of means to search for missing victims, as well as support the people in the area. Moreover, the Red River was forecast to reach water levels of 3–50 cm (1.2–19.7 in). [22]
On October 12, a landslide occurred in a district in Hòa Bình Province, burying four households. [23] The number of flooded houses rose to 16,700. More than 39,300 hectares of crops were damaged along with two dikes. Around 1,200 cattle and roughly 40,000 fowl were either killed or swept away by flooding and landslides. [23] Rainfall in Mai Châu District, Hoà Bình Province, reached 390 mm (15.3 in), while Kim Bôi District, Hoà Bình Province, had a total of 450 mm (17.7 in). In Lương Sơn District, Hoà Bình Province, 13 hectares of rice were damaged along with 97 hectares of other agriculture crops and 7 hectares of fruit trees. 6 km of roads and 4 km of canal were also damaged due to the flooding. [24] The Vietnam Red Cross offered about 250 million ₫ (US$11 thousand) to families affected by a landslide in Phú Cường, Tân Lạc District, Hòa Bình Province. [25]
Losses from damage in Yên Bái Province are estimated at 500 billion ₫ (US$22 million), [26] while Sơn La Province had 59 billion ₫ (US$2.6 million) [27] and Phú Thọ Province had 22.8 billion ₫ (US$1 million). [28] Lương Sơn district, Hoà Bình Province, suffered damage of about 25 billion ₫ (US$1.1 million), [24] and Lạc Sơn District, Hoà Bình Province, suffered damages of about 16 billion ₫ (US$704 thousand). [29] Hoa Binh province had total damages of 46 billion ₫ (US$2.02 million), including 9 billion ₫ (US$396 thousand) from Ky Son. [30] As of October 15, at least 68 people lost their lives; additionally, 30 were injured, and 34 are still missing. [31] Almost half of the dead (26 people) were in Hoà Bình Province. [32] In total, 100 people were killed and damages reached over 13 trillion ₫ (US$572 million). [19] [33]
Despite making landfall in Vietnam, 23W triggered severe flooding in Thailand and killed a total of 9 people. [33] As of October 19, damage from flooding estimated at US$30 million. [34]
A comprehensive humanitarian response was swiftly mobilized to address the urgent needs of affected communities across northern and central Vietnam. The Vietnam Red Cross, along with various local non-governmental organizations (NGOs) and international aid organizations such as the United Nations Development Programme (UNDP), [35] played a pivotal role in the immediate aftermath, distributing essential supplies such as food, clean water, clothing, and shelter materials to the displaced populations.

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.
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 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.
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.
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.
Vietnam was hit by several floods in 2019.
Tropical Storm Nangka, also known in the Philippines as Tropical Depression Nika, was a weak tropical cyclone which impacted Hainan and parts of Indochina, which had been affected by Tropical Storm Linfa just days earlier. Nangka in total caused 4 deaths and 5 missing in China and Vietnam.
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 Wipha was a tropical cyclone that caused significant damages in Vietnam and China. Wipha was the eleventh depression, and the ninth tropical storm of the 2019 Pacific typhoon season.
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.
