MANILA, Philippines (AP) — Tropical Storm Trami blew away from the northwestern Philippines on Friday, leaving at least 65 people dead in landslides and extensive flooding that forced authorities to scramble for more rescue boats to save thousands of terrified people, who were trapped, some on their roofs.

But the onslaught may not be over: State forecasters raised the rare possibility that the storm — the 11th and one of the deadliest to hit the Philippines this year — could make a U-turn next week as it is pushed back by high-pressure winds in the South China Sea.

A Philippine provincial police chief said Friday that 33 people were killed mostly in landslides set off by Trami in Batangas province south of Manila. That brought the overall death toll from the storm to at least 65.

Eleven other villagers remain missing in Batangas, Col. Jacinto Malinao Jr. told The Associated Press by telephone from the lakeside town of Talisay, where he stood beside a villager whose wife and child were buried in the deep mound of mud, boulders and trees.

With the use of a backhoe and shovels, police scrambled to search into 10 feet (3 meters) of mud, rocks and debris and found a part of a head and foot that apparently were those of the missing woman and child.

“He’s simply devastated,” Malinao said of the villager, a fisherman, whose wife and child were buried in the landslide that happened Thursday afternoon amid torrential rains while he was away tending to fish cages in a lake.

“He’s in shock and couldn’t speak and we’re only asking him to point to where their bedroom was located so we can dig in that part,” Malinao said.

The storm was last tracked at dawn blowing 125 kilometers (78 miles) west of the coastal town of Bacnotan in northern La Union province with sustained winds of up to 95 kilometers (59 miles) per hour and gusts of up to 115 kph (78 mph). It was moving northwest at 25 kph (15 mph) toward Vietnam, which was forecast to be lashed by Trami starting on Sunday if it stays on course.

The Philippine weather agency, however, said it's possible that high-pressure winds and other weather factors in the South China Sea could force the storm to turn back toward the Philippines.

President Ferdinand Marcos, sounding exasperated, inquired about that prospect in an emergency meeting with Cabinet members and disaster-response officials Friday about the response to the widespread devastation.

"What is the forecast for that? Is it possible it would return?” Marcos asked.

A government forecaster told him Trami could turn toward the western Philippines early next week, but its more likely to blow away from the Philippines again without making landfall.

"It doesn’t have to make landfall for the damage to occur,” Marcos said, citing the continuing downpours set off by Trami in the Philippines.

Marcos also cited another brewing storm in the Pacific Ocean that could again threaten the country.

"Oh God, it is what it is. We just have to deal with it,” Marcos said.

State forecaster Jofren Habaluyas told the AP that Trami's possible U-turn has drawn interest among government weather experts in Asia, including those from Japan, which has been providing information to the Philippines to help track the storm.

The 65 storm deaths included 26 villagers who died in floodwaters and landslides in hard-hit Bicol, an agricultural region and tourism destination southeast of Manila that is popular for Mayon, one of the country’s 24 most active volcanoes that has a near-perfect cone.

Although Trami did not strengthen into a typhoon, it dumped unusually heavy rains in some regions, including some that saw one to two months’ worth of rainfall in just 24 hours, inundating communities with flash floods.

Officials in Naga city, where 11 people died by drowning, and the outlying provinces of Camarines Sur and Albay pleaded for more rescue boats at the height of the onslaught to reach people trapped on the upper floors of their homes or on their roofs as floodwaters rose.

In the foothills of Mayon volcano in Albay province, mud and other debris cascaded toward nearby towns as the storm hit, engulfing houses and cars in black-colored mudflows.

More than 2.6 million people were affected by the deluge, with nearly 320,000 people fleeing into evacuation centers or relatives' homes, disaster-mitigation officials said.

The government shut down schools and government offices on the main northern island of Luzon. Inter-island ferry services were also suspended, stranding thousands.

In Vietnam, state forecasters warned of heavy rains in the central region. Prime Minister Pham Minh Chinh ordered coastal provinces to stay vigilant, closely monitor Trami’s course and brace for contingencies.

Last month, Typhoon Yagi battered Vietnam, killing 323 people and causing extensive damage valued at $3.3 billion, according to a Vietnamese government report.

Each year, about 20 storms and typhoons batter the Philippines, a Southeast Asian archipelago which lies between the Pacific Ocean and the South China Sea. In 2013, Typhoon Haiyan, one of the strongest recorded tropical cyclones, left more than 7,300 people dead or missing and flattened entire villages.
