Manila  - More than 1,000 people were stranded Friday in various ports in the Philippines after sea vessels were barred from sailing due to rough seas brought about by an incoming typhoon.

Coastguard commandant Admiral Wilfredo Tamayo said 1,392 passengers were stuck in several provinces as Typhoon Mirinae forced the cancellation of sea travel.

He said the number of stranded passengers would increase as Mirinae makes landfall late Friday or early Saturday near Manila.

The weather bureau said Mirinae was packing maximum sustained winds of 150 kilometres per hour (kph) and gusts of up to 185 kph. It was moving west south-west at 22 kph.

Classes in elementary and high schools were suspended in metropolitan Manila and nearby provinces after the weather bureau raised storm warnings in the areas.

Philippine authorities have asked people to skip going to the cemeteries at the weekend amid Mirinae's threat.

Millions of Filipinos usually visit the graves of their dead relatives on or before November 1, the traditional day for honouring the dead.

The weather bureau warned residents in low-lying areas and on mountain slopes to be prepared for flashfloods and landslides.

Nearly 1,000 people were killed three weeks ago in back-to-back storms that pummelled Manila and the northern provinces. More than 8 million people were affected by two cyclones. (dpa)
