Torrential rain following Typhoon Bualoi has triggered more flooding and landslides in Vietnam, where at least 19 people have been killed and more are missing.
More than 30cm of rain hit parts of the country within 24 hours, with forecasters on Tuesday warning heavy downpours would continue.
The prolonged rain caused flash floods and landslides that cut off roads and isolated communities from the northern mountains of Son La and Lao Cai provinces to central Nghe An province.
Rivers swollen by downpours and dam discharges have caused widespread flooding and landslides in the north.
The Thao River in Yen Bai rose well above emergency levels overnight, with water up to a metre deep gushing into homes and forcing evacuations.
Many streets in the capital, Hanoi, were flooded and authorities warned that people close to the Red River, which passes through the city, should take precautions.
State media said authorities were still searching for 13 missing people, including eight fishermen.
Typhoon Bualoi had already caused at least 20 deaths in the Philippines since Friday.
