Tens of thousands of people were also displaced by the onslaught in eastern areas of the Philippines.

Tropical Storm Aere hit on May 8 with winds of 85km (53 miles) per hour.

More than 50 domestic and international flights were cancelled or delayed, power was cut and ships told to stay inside coastal shelters.

The 11 people killed include nine in the provinces of Camarines Sur, Albay, Catanduanes, Leyte and Northern Samar. Another man was electrocuted, while one died in a truck accident.

Thousands were helped to move away from their farms around Mayon volcano in Albay, where landslides were threatening and heavy rains had caused rivers to flood.

The storm, known locally as Bebeng, is now surging across the country towards Luzon.

"We're advising residents in high-risk areas to pre-emptively evacuate before the storm hits," said Chito Castro, spokesman for the government's disaster-response agency.

The storm is expected to move on to Taiwan later in the week.
