Over the next 24 hours it will move west at a speed of 20 kph before changing direction and moving northwest.
By Sunday morning it is expected be reach the Vietnamese coast between Ha Tinh and Quang Nam provinces, where at least 235 have been killed or left missing missing by storms and floods since last month.
International weathering forecasting agencies predicted that Storm Vamco would make landfall over Ha Tinh and Quang Binh provinces on Monday.
Vamco is the third storm in November and 13th to hit Vietnam this year.
As a result, all sea and airports in the affected area of the storm will be closed when it makes landfall. Vessels sailing within the affected area should contact local authorities for assistance, when needed.
