Tropical depression moves slowly northwestward, dumps more rain in Da Nang
Due to the influence of the slowdown of the newly-developed tropical depression that lies in the west of Hoang Sa (Paracel) Islands in combination with the Intertropical convergence zone and easterly wave disturbances, the parts from Quang Binh to Quang Ngai, including Da Nang, will brace for further heavy rainfall from Thursday into Friday. The Da Nang government is urging authorities at local level and relevant units to continue to take steps to cope with heavy rains brought by the tropical depression.

The radius of strong winds at level 6 and the gusts as high as level 8 is about 80km from the tropical depression’s centre.
The depression will continue to move toward the northwest with velocity at 5-10km per hour over the next 24 hours, and it is expected to grow even stronger.

A tornado and strong wind watch has been issued for these areas by the national forecasters.
The south of the Gulf of Tonkin, the offshore areas stretching from Quang Tri to Ca Mau, Ca Mau to Kien Giang, the Gulf of Thailand, and the East Sea (including the waters of the Hoang Sa and Truong Sa islands) are expected to experience showers and severe thunderstorms with possible strong damaging winds and tornadoes.
From Thursday into Friday, the parts from from Quang Binh to Quang Ngai, including Da Nang, will brace for heavy to very heavy rain with a common rainfall of 150-300mm, and even more than 400mm in some places.
