MANILA - Heavy rains since Sunday night flooded large parts of Metro Manila and other parts of central and southern Luzon.

The red alert warning of PAGASA was still up over Metro Manila as of posting, which means heavy rains in the next 2 hours and high risk of serious flooding.

A forced evacuation was being undertaken in parts of Marikina City as water level in Marikina River continued to rise.
PAGASA rainfall data recorded 222.6 mm of rainfall in the last 9 hours at Science Garden, Quezon City. During Ondoy, the rainfall recorded at Science Garden was 341 mm in 6 hours.

MANILA (Reuters) - Deadly torrential rains submerged much of the Philippine capital and surrounding areas on Tuesday, forcing nearly 270,000 people to flee their homes with more flooding expected in the north of the country as a tropical storm passes through the region, officials said.

Steady rains for the past 10 days, killing more than 50 people, are set to continue until Wednesday, the Philippines weather bureau said, fuelled by tropical storm "Haikui" in the Philippine Sea northeast of Taiwan. The storm is headed for China's Zhejiang province where more than 250,000 people have been evacuated ahead of expected landfall late on Wednesday.

"It's like Waterworld," said Benito Ramos, head of the Philippines national disaster agency, referring to a Hollywood movie about a flooded world.

Schools, financial markets, and public and private offices were ordered shut, including outsourcing firms whose corporate clients are mainly from the United States and Europe.

Disaster officials said over half of Manila was swamped by floods as high as three metres, worsened by a high tide and the release of water from dams in surrounding provinces.

President Benigno Aquino, in an emergency meeting briefly interrupted by a power failure at the main army base in Manila, ordered officials to exert maximum effort to aid residents in flooded areas. Officials have deployed army troops, police and emergency workers with rubber boats and amphibious trucks.

The monsoon rains, which dumped about 300 mm (12 inches) or three times the daily average of 80-100 mm from late Monday to Tuesday, were the heaviest in three years, the weather bureau said.

Typhoon Ketsana, which swamped 80 percent of the capital in 2009, aided a monsoon downpour of more than 450 mm (18 inches) in a 24-hour period.

MAJOR ROADS INUNDATED

Most major roads in Manila were inundated by knee- to waist-deep floodwaters. Some flights were delayed or cancelled. Power, water and communications in flooded areas were disrupted.

Some of the affected residents were marooned on the roofs of their houses.

"There are about 5,000 people here," said Ester Ronabio, a public school teacher and volunteer in one of the temporary shelter areas in low-lying Marikina City in the eastern part of Manila. "We can't control the flow of people."

In a sign of the difficult scramble to move people to safety, Aquino appealed to an anti-graft court to release dozens of rubber boats held as evidence in a case against senior police officials for use in evacuation efforts.

Residents of Manila expressed concern the rains were a repeat of Typhoon Ketsana which killed more than 700 people and destroyed $1 billion worth of private and public property.

"The floods are so deep where we live, we don't want a repeat of Typhoon Ketsana a few years ago," Melanio David, a father of four, told Reuters. "We got scared so we evacuated last night."

What's different in this rainfall and Ondoy


By Kim Arveen Patria | Yahoo! Southeast Asia Newsroom – Tue, Aug 7, 2012
(UPDATE) The rainfall caused by the southwest monsoon in Metro Manila is almost as devastating to the volume of rain in the 2009 typhoon Ondoy, an official on Tuesday said.

Accumulated rainfall from 4:45 p.m. on Aug. 6 to 3 p.m. of Aug. 7 reached 472 millimeters monitored from the Quezon City Polytechnic University, even higher than Ondoy's accumulated 455 millimeters in 24 hours, Mahar Lagmay, who leads the inter-agency National Operational Assessment of Hazards Project (Project NOAH), said in a phone interview.

Lagmay, however, noted that a comparison cannot accurately be made as other observation posts have recorded lower rainfall levels. He also noted that Ondoy's flood peaked earlier than this monsoon.

"We also have to point out the difference in time frame. Rain due to Ondoy peaked for six hours while the rain currently caused by the monsoon is over an extended period," Lagmay said.

The weather bureau as of its 9:30 p.m. update meanwhile kept Metro Manila under a "red warning signal," noting that heavy to intense (10-25 mm/hr) with occasional to frequent torrential (over 30 mm/hr) may be expected in the next three hours.

There is no tropical storm within the Philippine area of responsibility but tropical storm Haikui located 300 kilometers northeast of Taiwan worsens the effect of the southwest monsoon, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said.

In its weather advisory, Pagasa noted "occasional to frequent rains over Luzon becoming moderate to heavy rains" in Metro Manila and the provinces of Ilocos, La Union, Pangasinan, Tarlac, Zambales, Bataan, Pampanga, Bulacan, Rizal, Cavite, Laguna, Batangas up to Wednesday.

Gradual improvement may be expected by Thursday until the weekend.

"Expect landslides/flashfloods in mountainous areas and floods in low lying areas," Pagasa said.
