Il Nuovo Postiglione - Philippines warns of 'potentially catastrophic' Super Typhoon Man-yi

More than 650,000 people have fled their homes ahead of Super Typhoon Man-yi, which is expected to make landfall later Saturday or early Sunday, becoming the sixth major storm to pummel the archipelago nation in the past month.

With wind gusts of up to 240 kilometres per hour (about 149 miles per hour), Man-yi was on track to slam into the sparsely populated island province of Catanduanes as a super typhoon or "near peak intensity", the weather service warned.

"Potentially catastrophic and life-threatening situation looms for northeastern Bicol region as Super Typhoon 'Pepito' further intensifies," the forecaster said in its latest update, using the local name for the storm and referring to the southern part of the main island of Luzon.

Up to 14-metre (46-feet) high seas were expected around Catanduanes, while more than 7.6 million people were at risk from storm surges of one to three metres, the forecaster said.

At least 163 people died in the five storms that pounded the Philippines in recent weeks that also left thousands homeless and wiped out crops and livestock.

The government urged people Saturday to heed warnings to flee to safety.

"If preemptive evacuation is required, let us do so and not wait for the hour of peril before evacuating or seeking help, because if we did that we will be putting in danger not only our lives but also those of our rescuers," Interior Undersecretary Marlo Iringan said.

In Albay province, Legazpi City grocer Myrna Perea was sheltering with her fruit vendor husband and their three children in a school classroom with nine other families after they were ordered to leave their shanty.

Conditions were hot and cramped -- the family spent Friday night sleeping together on a mat under the classroom's single ceiling fan -- but Perea said it was better to be safe.

"I think our house will be wrecked when we get back because it's made of light materials -- just two gusts are required to knock it down," Perea, 44, told AFP.

"That's why we evacuated. Even if the house is destroyed, the important thing is we do not lose a family member."

Scientists have warned climate change is increasing the intensity of storms, leading to heavier rains, flash floods and stronger gusts.

About 20 big storms and typhoons hit the Southeast Asian nation or its surrounding waters each year, killing scores of people, but it is rare for multiple such weather events to take place in a small window.

- Forced evacuations, curfew -

Evacuation centres were filling up on Catanduanes island in the typhoon-prone Bicol region, with the weather forecaster warning of "widespread incidents of severe flooding and landslides".

More than 400 people were squeezed into the provincial government building in the capital Virac, with new arrivals being sent to a gymnasium, provincial disaster officer Roberto Monterola told AFP.

Monterola said he had dispatched soldiers to force about 100 households in two coastal villages near Virac to move inland due to fears storm surges could swamp their homes.

"Regardless of the exact landfall point, heavy rainfall, severe winds, and storm surges may occur in areas outside the predicted landfall zone," the forecaster said.

The mayor of Naga city in Camarines Sur province imposed a curfew from midday on Saturday in a bid to force residents indoors.

- Back 'to square one' -

In Northern Samar province, disaster officer Rei Josiah Echano lamented that damage caused by typhoons was the root cause of poverty in the region.

"Whenever there's a typhoon like this, it brings us back to the mediaeval era, we go (back) to square one," Echano told AFP, as the province prepared for the onslaught of Man-yi.

All vessels -- from fishing boats to oil tankers -- have been ordered to stay in port or return to shore.

Nearly 4,000 people were stranded after the coast guard shut 55 ports.

The volcanology agency also warned heavy rain dumped by Man-yi could trigger flows of volcanic sediment, or lahars, from three volcanos, including Taal, south of Manila.

Man-yi will hit the Philippines late in the typhoon season -- most cyclones develop between July and October.

Earlier this month, four storms were clustered simultaneously in the Pacific basin, which the Japan Meteorological Agency told AFP on Saturday was the first time such an occurrence had been observed in November since its records began in 1951.
