Typhoon Doksuri, known in the Philippines as Tropical Storm Maring, was a strong 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.

During September 9, the Joint Typhoon Warning Center (JTWC) began monitoring on a tropical disturbance that had developed about 836 km (519 mi) west-northwest of the province of Eastern Samar.[1] During the next day, the Japan Meteorological Agency (JMA) classified the system as a weak tropical depression.[2] Six hours later, the JMA started to issue advisories on the depression when it had winds of 55 km/h (35 mph).[3] On 21:00 UTC of September 11, the JTWC followed suit, giving the designation of 21W.[4] The JMA upgraded 21W to a tropical storm during September 12, giving the name Doksuri, the nineteenth named storm of the annual typhoon season.[5] By September 13, robust convection had persisted near its low-level circulation center (LLCC) along with deep convective banding and a depicted "ragged" microwave eye feature. This prompted the JTWC to classify Doksuri as a tropical storm.[6] About six hours later, Doksuri's LLCC became well-defined,[7] and Doksuri strengthened into a severe tropical storm from the JMA.[8]
By September 14, strong convection was found to the south of its LLCC as convective banding began to wrap into a nascent eye.[9] Doksuri strengthened into a Category 1-equivalent typhoon. Around this time, Doksuri was already located in an area of low vertical wind shear along with warm sea-surface temperatures of about 30–31°C (86–87.8°F).[9] The JMA followed suit on upgrading Doksuri to a typhoon on 12:00 UTC of the same day.[10] With a slowly-developing eye with constant convection around its LLCC, Doksuri strengthened into a Category 2-equivalent typhoon.[11]

Doksuri, which is known as Maring, affected the Philippine archipelago of Luzon as a tropical storm. Shortly after when PAGASA began monitoring on the system, they already raised a Storm Signal Warning #1 over in the Southern Luzon portion, including provinces of Camarines Sur and Aurora on September 11.[19] Hours later, Signal Warning #1 was expanded to as west as Metro Manila, as north as Pangasinan and La Union, while every province in Central Luzon (Region III) was in that area. Moreover, local government units declared class suspensions to many places, especially in the capital region and the province of Bulacan for Tuesday, September 12.[20] Domestics flights were already canceled from the Ninoy Aquino International Airport while bus trips were canceled in the Quezon-Aurora area.[21] After the storm, on September 13, officials in the Cordillera Administrative Region (CAR) had warned residents to refrain from doing outdoor activities over in mountainous areas, especially in Benguet, for possibilities of landslides.[22]
Laguna was one of the provinces that got hit hard by the storm as the city was placed under a state of calamity after it had "too much rainfall" that produced further flash floods and landslides.[23] Malacañang had provided P650 million (US$12.75 million) worth of relief goods and funds for victims while the Department of Health (DoH) had offered P20 million (US$392 thousand) of supplies for provinces from Cagayan Valley (Region II) down to Bicol (Region V).[23] Over in the Quezon province, three buses and a car were stranded in flooded streets and the 25 passengers in one bus were rescued later that day. Quezon officials deployed rescue boats and military trucks the rescue efforts while the Philippine Army's 2nd Infantry Division has deployed a rescue team in Calabarzon.[24] About 1,857 families or 7,549 people were staying in 116 evacuation centers over in Laguna and Quezon.[25] At least 2,103 families or 8,794 persons were affected in 109 barangays in the regions of Central Luzon, Metro Manila and the Calabarzon. The Department of Social Welfare and Development (DSWD) allocated a total of P577.8 million (US$11.34 million) as standby funds for affected families while 18,000 food packs were prepositioned.[25]
According to the NDRRMC, a total of 8 people are dead while damage losses were about Php267 million (US$5.24 million), as of September 19.[12]
Vietnam
Typhoon Doksuri was the tenth storm to affect Vietnam and considered it as the "most powerful storm in a decade".[26] As early as September 13, authorities over the northern and central provinces banned from going to sea.[27] Vietnam was placed under a red warning, which stands for "very high" risks. Waves as high as 32 ft (10 m) were predicted offshore. Coastal provinces, therefore, announced plans to shut down beaches and ban fishing by September 14.[28] The Red Cross Society has sent missions to Ha Tinh and Quang Binh and mobilized forces to support people in storm-hit areas during September 15.[29] About 1,500 villagers were evacuated over in the Thua Thien-Hue province due to water erosion.[30] In Vietnam's capital city of Hanoi, 33 flights were canceled, while Vietnam Railways canceled seven passenger trains and five cargo trains in the Ha Tinh and Quang Binh provinces.[31] About 80,000 people have evacuated over in Central Vietnam.[26]
Doksuri brought wind gusts of up to 135 km/h (82 mph), which cut power and affected a total of 1.5 million people, although the Hong Kong Observatory (HKO) measured gusts of up to 160 km/h (102 mph).[26][31][32] The provinces of Thanh Hóa up to Quang Ngai saw total precipitation of 100-200 mm (3.9-7.8 in), with some reports of high as 300 mm (11.8 in), along with gusts of up to 80-100 km/h (45-65 mph). Water erosion affected 700 meters of sea dike in a village in Thuan An.[31] Seven fishing vessels and 183 small boats sank while 10 small irrigation dams were damaged.[33] 220 small boats were washed away over in the provinces of Nam Dinh and Quang Nai.[32] In agriculture, Doksuri affected 4,473 hectares of rice with an additional 8,277 hectares for other crops, as well as 16,108 hectares of aquaculture.[33] Overall, 13,000 hectares of perennial crops were damaged, mostly over in the Quang Binh and Quang Trinh provinces.[32] The storm also damaged a total of 10 km of highways and 17.9 km of local roads.[33] A total of 23,968 houses had damaged roofs, especially from the Ha Tinh province.[34] During September 16, Vietnam Electricity resumed power only to seriously affected areas such as Dong Hoi, Quang Binh and Nghe An.[33] On September 17, the Vietnam Red Cross (VRC) offered aid of about ₫1.5 billion (US$66 thousand) to six provinces that were hit by the typhoon. Moreover the Coca-Cola company of Vietnam sent 24,000 water bottles to residents of in the Quang Binh province.[29] Around the same time, 31,000 soldiers and police were mobilized to help residents in hard-hit provinces.[35] By September 19, a total of 1.3 million households had been supplied with electricity again.[32]
Damages over in the Thanh Hóa Province were topped to ₫1 trillion (US$44 million),[29] while the Quang Binh province had a total damage of ₫8 trillion (US$352 million); damage in Hà Tĩnh reached 7.5 trillion (US$330 million);[16] damage to the power grid reached 215 billion dong (US$9.5 million).[36] In total, damages from Doksuri were estimated about ₫18 trillion (US$792 million),[32][14] while the death toll has been set at 15,[15][16] along with 200 people injured and 3 missing.[37][35] [38][39]
Other areas
Despite making landfall in Indochina, Doksuri affected Hainan and total economic losses were estimated to be CNY 100 million(USD 15.3 million).[40] Flooding triggered by the storm in Laos killed one person and total damage reached ₭N55.5 billion (US$6.68 million).[18]
