HANOI — Hundreds of thousands of people in Vietnam’s Mekong Delta were removed from their homes as the region braced for the arrival of Typhoon Tembin after the storm left up to 230 people dead in the Philippines.
Weather forecasters expect the delta’s southern tip to be in Tembin’s path. They said heavy rain and strong winds, which started Monday night, could cause serious damage in the vulnerable region, where facilities are not built to cope with such severe weather.
National television station VTV reported that several hundred thousand people were taken from their houses, which are mostly made from tin sheets and wooden panels.
In Vung Tau city, thousands of fishing boats halted their monthslong fishing trips to return to shore.
Typhoons and storms rarely hit the Mekong Delta. But in 1997, Tropical Storm Linda swept through the region, killing 770 people and leaving more than 2,000 others missing.
Over the weekend, Tembin unleashed landslides and flash floods that killed more than 230 people, based on reports from provincial officials.
Romina Marasigan of the government’s main disaster-response agency said the official government death toll was 164 people, with 171 others missing.
Marasigan warned of possible double counting amid the confusion in the storm’s aftermath and said the higher estimates needed to be verified.
More than 97,000 people remained in 261 evacuation centers across the southern Philippines on Monday, while nearly 85,000 others were displaced and staying elsewhere, the National Disaster Risk Reduction and Management Council said.
The hardest-hit areas were Lanao del Norte and Lanao del Sur provinces and the Zamboanga Peninsula. Tembin hit the Philippines as a tropical storm but strengthened into a typhoon before blowing out of the country Sunday into the South China Sea toward Vietnam.
Philippine officials had warned villagers in accident-prone areas to leave early as Tembin approached and the government was trying to find out what caused the widespread storm deaths, Marasigan said. She added that it was difficult to move people from homes before Christmas.
‘‘We don’t want to be dragging people out of their homes days before Christmas, but it’s best to convince them to quietly understand the importance of why they are being evacuated,’’ Marasigan said at a news conference in Manila.
An interisland ferry sank off northeastern Quezon province Thursday after being lashed by fierce winds and big waves, leaving at least five people dead. More than 250 passengers and crewmen were rescued.
Earlier in the week, another tropical storm left more than 50 people dead and 31 others missing, mostly due to landslides, and damaged more than 10,000 houses in the central Philippines.
In a separate development, a passenger bus collided with a van carrying pilgrims to Christmas Mass at a church in the northern Philippines on Monday, leaving 20 people dead and more than two dozen injured, police said.
Police Chief Superintendent Romulo Sapitula said all those killed in the predawn collision in La Union province’s Agoo town were in the van, known as a jeepney.
Another 10 van passengers, along with the driver and 17 other occupants of the bus, were injured.
