Tropical Storm Trami: More than 20 dead in Philippine floods

Rescuers were also searching for a missing fisherman after a boat sunk in the waters off Bulacan province, west of Manila, the local disaster agency told AFP news agency.

Rescue work has been difficult as the winds were causing a strong current, said Geraldine Martinez, a rescue officer in Bulacan’s Obando municipality.

At least a dozen flights across the country had been cancelled.

Even as it was on its way out of the Philippines, officials have continued to warn of heavy rainfall, flooding, landslides and storm surges.

Another low pressure area off Bicol could intensify into a tropical depression by the end of the week, Ms Claren said.

The Philippines is hit by an average of four typhoons annually, some of them deadly.

However, recent years have seen typhoons with stronger, more destructive winds and heavier rains.
