Typhoon Son-Tinh has been downgraded to a tropical depression, but is continuing to batter parts of China with strong winds and heavy rainfall.
Already two people have been killed in Vietnam, where the storm made landfall in the north of the country and forced the evacuation of around 100,000 people.
Thousands of homes were damaged with winds of up to 140 kilometres per hour and torrential rains.
"Right now the damage reports are still pretty sketchy," Huy Pham, Save the Children's Vietnam country director told Radio Australia's program.
"This is the eighth storm to impact Vietnam this year, and by far the largest."
The charity was preparing to send hygiene kits and household kits to some of the worst-affected areas.
Before hitting Vietnam, typhoon Son-Tinh killed at least 27 people and left nine others missing as it swept through the Philippines.
Southern China is currently been affected by the weather system and the Guang-xi region recorded 140.5 millimetres of rainfall in an hour.
By Monday morning the official Xinhua news agency had confirmed one person dead and five missing in the southern province of Hainan.
