Over 200,000 people in the Philippines were ordered to evacuate their homes on Saturday as the most powerful typhoon of the year so far approaches the country, news agency Agence France-Presse said.

"Typhoon Goni is expected to graze the southeastern tip of the main island of Luzon early Sunday before making landfall in the afternoon with wind speeds of up to 205 kilometres (127 miles) per hour", the state weather forecaster said. 

It comes a week after Typhoon Molave slammed into the same region, killing 22 people and flooding low-lying villages and farmland, before sweeping across the South China Sea to Vietnam. 

"It looks like we will have really strong winds, increasing the chances of widespread flooding and landslides," Mark Timbal, spokesman for the National Disaster Risk Reduction and Management Council, told local broadcaster ABS-CBN.

"Storm surges are imminent on our east coast. We are monitoring Mayon and Taal volcanos for possible volcanic mud flows."

Authorities on Saturday ramped up preparations in the Bicol region southeast of Manila, marshalling rescue vehicles, emergency response teams and relief goods ahead of the typhoon.

The weather service has warned of a "moderate to high risk" of storm surges up to three metres (10 feet) high along the east coast over the next two days.  

"Violent winds and intense rainfall" are expected that could trigger flooding and landslides in a region of more than 20 million people, it said. 

The Philippines is hit by an average of 20 storms and typhoons every year, which typically wipe out harvests, homes and infrastructure, keeping millions of people perennially poor, the report said.

Its deadliest on record was Super Typhoon Haiyan, which unleashed giant waves on the central city of Tacloban and left more than 7,300 people dead or missing in 2013, the report added.
