A broad low pressure area formed east of Mindanao, Philippines on August 3, after Jebi made landfall over northern Vietnam and dissipated. Early on August 5, the JMA and PAGASA reported that a tropical depression had developed within a favourable environment for further development, about 145 km (90 mi) to the northeast of Puerto Princesa in Palawan with the latter naming it as Kiko.[3][4][5]

Later that day as the system consolidated further the JMA reported that the depression had developed into a tropical storm and named it Mangkhut, before the JTWC initiated advisories and designated it as Tropical Depression 10W.[3][6][7]

Over the next couple of days the system moved towards the north-northwest before it made landfall in Northern Vietnam during August 7. Later that day, it was said that 2 people died due to strong winds and falling debris. On August 8, Mangkhut was weakened to a tropical depression by the JMA, and JTWC later that day. Mangkhut was then last noted early the next day as it dissipated over Laos. During August 9, a total of 3 people were killed.[3]

Impact

Vietnam

In the afternoon of August 7, a teenager named Pham Thanh Son (16 years old, resident of Dang Giang Ward, Ngo Quyen District) heard information about Mangkhut affecting Hai Phong, so he and his three friends took two motorbikes to go watch the storm. All 4 people stopped at the beach area in front of the Hai Yen hotel to watch the waves. Son ran along the embankment all by himself, and he was suddenly swept into the sea by the waves.[8][9][10] Downpours throughout Wednesday night, August 7 until Thursday, August 8 dropped rainfall 80 mm (3.1 in) deep on streets of the capital, causing difficulties for many people going to work. Meanwhile, rainfall totals went up to about 300 mm (12 in) in central Thanh Hóa and northern Hai Phong city, with wind speeds hitting 62–88 km/h (40–55 mph).[11][12]

Tropical Storm Mangkhut weakened as it made landfall over Thanh Hóa Province and Ninh Bình Province delta late evening on 7 August. A peak gust of 30 m/s was recorded at Nam Dinh, and accumulated precipitation total during the time of Mangkhut over Southeast part of Vietnam was 336mm which was recorded at Ky Anh. A central pressure value of 992.2mb was also recorded at 15:20 UTC in Thanh Hoa city. Four persons were killed, five were injured due to the impact of Mangkhut.[1]

Total damage in Vietnam reached 1.3 trillion dong (US$56.1 million).[13][14]
