Volkswacht Bodensee - Typhoon flooding kills 5, strands thousands in central Philippines

Entire towns on the island of Cebu have been inundated, while cars, trucks and even massive shipping containers could be seen swept along by muddy floodwaters in videos verified by AFP.

In the 24 hours before Kalmaegi's landfall, the area around provincial capital Cebu City was deluged with 183 millimetres (seven inches) of rain, well over its 131-millimetre monthly average, state weather specialist Charmagne Varilla told AFP.

"The situation in Cebu is really unprecedented," provincial governor Pamela Baricuatro said in a Tuesday Facebook post.

"We were expecting the winds to be the dangerous part, but... the water is what's truly putting our people at risk," she said. "The floodwaters are just devastating."

Local disaster official Ethel Minoza told AFP the bodies of two children had been recovered in Cebu City, where rescuers were still attempting to reach residents trapped by floodwaters.

At least three other deaths have been confirmed elsewhere, including an elderly resident who drowned in an upper floor of their home in Leyte province and a man struck by a falling tree in Bohol.

Don del Rosario, 28, was among those in Cebu City who sought refuge on an upper floor as the storm raged.

"The water rose so fast," he said. "By 4:00 am, it was already uncontrollable -- people couldn't get out (of their houses)."

"I've been here for 28 years, and this is by far the worst we've experienced."

Scientists warn that storms are becoming more powerful due to human-driven climate change. Warmer oceans allow typhoons to strengthen rapidly, and a warmer atmosphere holds more moisture, meaning heavier rainfall.

Hundreds still living in tent cities after a 6.9-magnitude quake rocked the island in late September were "forcibly evacuated for their own safety", Cebu information officer Rhon Ramos told AFP by phone.

In total, nearly 400,000 people were pre-emptively moved from the typhoon's path, Rafaelito Alejandro, deputy administrator at the Office of Civil Defense, said at a Tuesday press briefing.

- More storms expected -

As of 2:00 pm (0600 GMT), the typhoon was moving westwards through the Visayan island chain, with winds of 130 kilometres (81 miles) per hour and gusts of 180 kph toppling trees and downing power lines.

The Philippines is hit by an average of 20 storms and typhoons each year, routinely striking disaster-prone areas where millions live in poverty.

With Kalmaegi, the archipelagic country has already reached that average, weather specialist Varilla told AFP, adding at least "three to five more" storms could be expected by December's end.

Just before midnight in Dinagat Islands province, where Kalmaegi first made landfall, Miriam Vargas sat with her children in the dark, praying as the winds slammed against the walls of her home.

"The electricity went out about an hour ago, and we cannot see anything," the 34-year-old single mother told AFP.

The Philippines was hit by two major storms in September, including Super Typhoon Ragasa, which tore the roofs off buildings on its way to killing 14 people in nearby Taiwan.
