More than 300 kilometres of coastline will be directly affected, including Da Nang, Hue, Quang Tri and Quang Binh.
The information was given out in an online conference held by the National Center for Hydrometeorological Forecasting on Monday.
A total of 230,000 people were being evacuated from high-risk areas in central Vietnam. Operators of fishing, transport and tourist boats and vessels were requested to take shelter or move out of the typhoon's path, and banned vessels from sailing to the sea - the government reported on its website. Food, accommodation and emergency rescues were ordered to be ready to respond to requests.
