100 dead, 300,000 displaced in Luzon alone.

(CNN) — The death toll from flooding in the Philippines caused by Tropical Storm Ketsana climbed to at least 100 on Monday, disaster officials said.

Flood water began to subside after a weekend that saw the capital, Manila, hit with its heaviest rainfall in more than 40 years.

More than 80 percent of the capital was under water at one point Sunday. The deluge swallowed whole houses and buses.

Manila, in the island of Luzon, and the nearby province of Rizal bore the brunt of the storm. People huddled on rooftops Sunday waiting on army helicopters to pluck them to safety. Others used ropes to wade through waist-deep muddy waters.

Power and water supply failed in some areas. Roads were rendered impassable, making rescue efforts challenging.

“Right now the challenge is to find out how many people have actually died and how many people we have to take care of in terms of people who’ve been displaced,” said Richard Gordon, the chairman of the Philippines National Red Cross.

“We’re really talking about maybe hundreds of thousands of people,” with about 280,000 to 300,000 displaced in the island of Luzon alone, he said.

Though the Philippines is no stranger to floods, Saturday’s downpours approached a record, with a month’s worth of rain falling within six hours.

Officials worried that if the rains return, they could bring more floods if reservoirs burst.

“We’re hoping that there will be no more breaching of the dams,” Gordon said. “That’s one of the things that are very disconcerting to many people right now.”
