Heavy rains are expected across northern and north-central provinces in Vietnam from Thursday as a new typhoon, Dianmu, is getting stronger.
Dianmu, the third typhoon to hit the country this year, is expected to make landfall on Friday afternoon, the National Center for Hydro-meteorological Forecasting said.
It is now moving west, causing rough seas and bringing winds of up to 100 kph.
Downpours of up to 500mm from August 18-20 may trigger flash floods and landslides across the region.
Rough seas with waves of four meters high are forecast for the coastline from the central province of Binh Thuan down to Ca Mau in the south due to strong winds, according to the meteorology center.
Early this month, Typhoon Nida hit northern region, leaving four deaths in its wake after triggering flash flooding in Lao Cai Province.
