Tropical storm Doksuri has entered the East Vietnam Sea, making it the tenth typhoon in the area this year, the local meteorological center said late Tuesday.
A tropical depression developed into typhoon Doksuri after passing through the central Philippines.
The storm was positioned about 850 kilometers southeast of the Hoang Sa (Paracel) Archipelago by around 4:00 pm on Tuesday, packing winds of between 60 and 75km per hour and squalls of up to 117km an hour, according to the National Center for Hydro-meteorological Forecasting.
Doksuri was forecast to travel northwestward at a velocity of 15 to 20km per hour while picking up in strength.
It is expected to be 460 kilometers southeast of the Hoang Sa Archipelago by 4:00 pm on Wednesday, producing winds of 75 to 100km per hour and squalls reaching 149km an hour.
The typhoon will continue northwestwards at 15km per hour in the next 24 to 48 hours.
As of 4:00 pm on Thursday, it is anticipated to reach north of Hoang Sa, with winds of between 115 and 135km per hour and squalls of up to 183km an hour.
Under the influence of the storm, rough seas will occur in the northern and central parts of the East Vietnam Sea.
According to Le Thanh Hai, deputy director of the National Center for Hydro-meteorological Forecasting, the development of Storm Doksuri is complicated and requires close attention as it is expected to interact with Typhoon Talim in the Pacific Ocean.
