Rescue teams searched for more signs of life after a series of deadly landslides in central Vietnam caused by heavy rains from Typhoon Molave, as yet another powerful storm barrelled towards the southeast Asia region.

Helicopters, soldiers and search dogs have been deployed to look for dozens of people feared dead in Vietnam in at least five mudslides in a central region battered by weeks of intense weather and the worst floods in years.

Molave has killed close to 40 people since it arrived in Vietnam two days ago, although many people were rescued yesterday, including three fishermen found in the sea by a cargo vessel and 33 people pulled from a tiny village buried by earth.

Central Vietnam has had a tough year, grappling with typhoons that killed at least 160 people, left dozens missing, devastated towns, wiped out crops and forced hundreds of thousands into shelters.

Meanwhile, a another storm named Goni gathered strength as it edged slowly towards the Philippines, packing winds of up to 165km/h.

It could make landfall in the Philippines early Sunday, with winds of up to 185km/h, its weather agency said.

Molave killed 22 people in the Philippines.

Goni is on course to reach central Vietnam later next week and would be the country's ninth typhoon this year.
