Typhoon Megi is gathering strength and heading towards southern China, meteorologists said, after leaving 200,000 Filipinos homeless.
The severe storm left a trail of destruction in its wake after hitting the northern Philippines on Monday.
Officials there said at least 200,000 people remained homeless with the cost to infrastructure still unknown.
The storm is described as the worst in many years, but predictions vary about where it will make next landfall.
People in the Chinese province of Guangdong and Hong Kong are stockpiling food ahead of the storm, which has been gathering strength over the South China Sea.
Ships and fishing boats have been told to stay in harbour, as Hong Kong's weather officials predicted winds of up to more than 185 km/hour(115mph).
