More than 100 people are dead or missing after Tropical Storm Trami devastated the Philippines, causing floods and landslides and forcing tens of thousands to evacuate their homes.

Philippine President Ferdinand Marcos Jr. In a Facebook post on Saturday, he said the aftermath of Trami, known as Kristine in the Philippines, was “terrible” and a time of “tremendous loss.”

Nearly 130 people are dead or missing in the northwestern Philippines, the Associated Press reported, adding that half a million people fled to emergency centers. The storm was the deadliest of the 11 storms to hit the Philippines this year.

According to local media reports, one or two months’ worth of rainfall (more than 19 inches) fell in 24 hours in some areas.

“There was so much water,” Marcos said, adding that many areas were flooded and access was difficult.

Authorities are mobilizing government resources to provide food, medical supplies and financial assistance to those affected by the floods and landslides, Marcos said, adding that the storm “inundated communities, displaced families and shattered livelihoods.”

Talisay, a town in Batangas province about 40 miles south of Manila, was one of several towns destroyed by Trami. The Philippine Civil Defense Agency said Sunday that a state of emergency was declared in Quezon City, northeast of Manila.

Bicol was among the worst-hit regions, with waters inundating many residential areas and agricultural lands. According to local media reports, floodwaters submerged most of Naga City.

“I make this promise to our people,” Marcos said on social media. “Help is on the way. It will come by land, air and even sea.”

During an emergency meeting, Marcos expressed concern that the storm, which reached central Vietnam on Sunday, could make a U-turn this week as it was pushed back by winds in the South China Sea, the AP reported.

On Saturday, Marcos visited those affected by the storm in Bula, Camarines Sur, including evacuation centers, his office said.

His office said in a statement on Saturday that it was crucial to find a “long-term solution” to the flooding, which officials attributed to climate change.

Rain, deadly floods and typhoons occur frequently in the Philippines, which consists of more than 7,000 islands. Floods throughout this year have raised concerns that climate change is driving extreme weather and will make such events more common.

According to The Washington Post, droughts and floods are closely linked to human-caused warming; This increases humidity and heat indices, making the world wetter and causing extreme precipitation to occur more frequently.
