MANILA, Philippines (AP) — Torrential rain set off by an approaching tropical storm swamped eastern Philippine cities and towns overnight in widespread flooding that trapped people, some on their roofs, and sparked frantic appeals for rescue boats and trucks, officials said Wednesday.

The government shut down public schools and government offices — except those urgently needed for disaster response — on the entire main island of Luzon to protect millions of people as Tropical Storm Trami blew closer from the Pacific.

At least person died after being hit by a fallen tree branch in central Masbate province while seven others were reported missing, including three men who sailed to fish in the high seas from Masbate but haven’t returned, officials said.

The storm was about 310 kilometers (193 miles) east of Baler town in the northeastern province of Aurora with sustained winds of 85 kilometers (53 miles) per hour and gusts to 105 kph (65 mph). Its wide rain band could dump up to 20 centimeters (8 inches) of rainwater in one day of intense downpours in the most vulnerable provinces on its path, according to state forecasters.

The storm was forecast to hit Aurora’s coast Wednesday night to early Thursday, then barrel across northern Luzon’s mountain range, valleys and plains before exiting to the South China Sea later in the week, they said.

Thousands of villagers have evacuated to emergency shelters in northeastern provinces, and storm warnings were raised in more than two dozen northern and central provinces, including in the densely populated capital of Manila, which was not in the storm’s direct path but could be lashed by its pounding rains.

President Ferdinand Marcos Jr. canceled all his appointments Wednesday and convened an emergency meeting in military headquarters to discuss disaster mitigation efforts, Communications Secretary Cesar Chavez said.

During the meeting, Defense Secretary Gilberto Teodoro said the military’s aircraft and ships would be used for evacuations and disaster response. He said additional airlift power could be provided by friendly countries, including Singapore, if needed.
