Vietnam was bracing for Tropical Storm Doksuri which killed at least four people and left another six missing in the Philippines.

Doksuri, which swept through the Philippines Tuesday as Tropical Depression Maring, has strengthened to a severe tropical storm with wind speed of up to 115 kilometers per hour (71 mph) and is expected to upgrade to a typhoon Friday before making landfall in central Vietnam, according to Vietnam weather forecast center.

The weather forecasters warned of heavy rains, floods and landslides in some northern and central parts of the country.

Speaking at an emergency meeting Thursday, Deputy Premier Trinh Dinh Dung ordered the evacuation of people in high-risk areas.
