Tens of thousands evacuate as super typhoon Rai slams into Philippines

Thousands of people in the Philippines have fled their homes and beachfront resorts as super typhoon Rai slammed into the country, with a charity warning the storm could hit coastal communities "like a freight train".

Rai was packing maximum sustained winds of 195 kilometres an hour as it made landfall on the southern island of Siargao at 0530 GMT on Thursday, the state weather forecaster said.

It is the strongest storm to hit the disaster-prone country this year.

"This monster storm is frightening and threatens to hit coastal communities like a freight train," said Alberto Bocanegra, head of the International Federation of Red Cross and Red Crescent Societies in the Philippines.

"We are very concerned that climate change is making typhoons more ferocious and unpredictable," he added.

More than 90,000 people sought emergency shelter as the storm charged across the Pacific Ocean, disaster agencies said.

Evacuations were still under way in areas in the typhoon's path. 

Among the evacuees were domestic tourists visiting the country's famed beaches and dive spots ahead of Christmas.

In the town of Dapa, families slept on the floor of a sports complex turned into a temporary evacuation centre.

'Brace for strong winds'

Scores of flights have been cancelled and dozens of ports temporarily closed as the weather bureau warned several metre-high storm surges could cause "life-threatening flooding" in low-lying coastal areas.

Weather forecaster Christopher Perez said the winds could "topple electric posts and trees" and damage houses made of light materials.

"Brace for heavy rains, brace for strong winds too," Perez told a briefing.

The weather bureau warned "very destructive" winds could cause "heavy to very heavy damage to structures and vegetation", along with widespread flooding and rain-induced landslides.

Typhoon season in Philippines

Rai, locally named "Odette", is hitting the Philippines late in the typhoon season, with most cyclones developing between July and October.

It is the second super typhoon to threaten the country since September when Chanthu grazed the northeastern tip of the main island of Luzon.

Scientists have long warned that typhoons are becoming more powerful, and strengthening more rapidly, as the world becomes warmer because of man-made climate change. 

A super typhoon is also known as a category five hurricane in the United States.

The Earth tends to experience around five storms of that power a year.

The Philippines – ranked as one of the world's most vulnerable countries to the impacts of climate change – is hit by an average of 20 storms and typhoons every year, which typically wipe out harvests, homes and infrastructure in already impoverished areas.
