Typhoon Wipha has caused major flight disruptions in Hong Kong and at some nearby airports in China as it moved west along the southern coast.

Airports in Hong Kong, Shenzhen, Zhuhai and Macao cancelled or postponed all their daytime flights, their websites showed on Sunday. Some high-speed train services in the area were suspended.

The Hong Kong Observatory issued a hurricane signal No 10, its highest warning. The eye of the storm was passing just south of the city around midday with maximum sustained winds of 140km/h, the Observatory said.

The government said over 200 people had headed to public shelters and that it had received dozens of reports of fallen trees. Hong Kong Disneyland and other amusement parks were closed.

The storm, which reached typhoon strength overnight, was headed toward Macao and the neighbouring Chinese city of Zhuhai. It was forecast to make landfall late Sunday and continue moving west, reaching Vietnam later this week.

Wipha, which is a Thai name, passed over the Philippines at tropical storm strength and drenched parts of Taiwan on Saturday.

In the Philippines, the storm intensified seasonal monsoon rains, leaving at least one villager dead in floodwaters in northern Cagayan province.

More than 370,000 people were affected by days of stormy weather, including 43,000 who fled to government-run emergency shelters or homes of relatives due to flooding, landslides and fierce wind.

More than 400 houses were damaged in the onslaught, officials said.
