MANILA, Philippines—Hours of heavy rain spawned by a low pressure area (LPA) off Batangas triggered floods in Metro Manila and provinces in Southern and Central Luzon, prompting the suspension of classes and work in several government offices, cancellation of domestic flights, heavy traffic in major roads and two major dams reaching critical levels.
The rain began pouring after midnight Monday and continuous to be felt until late Tuesday noon.
“Its circulation is wide, that’s why it affected a large area. It has a wide band of clouds. It’s a mini storm without the winds,” weather forecaster Jori Loiz said in an interview before noon Tuesday.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration recorded light to moderate to heavy to intense rainfall in Tanay, Rizal; Sangley, Cavite, and Science Garden in Quezon City, becoming torrential at the Port Area in Manila.
Some 43.4 millimeters of rainfall (torrential) was recorded at the Port Area, 22.9 mm in Science Garden, and 22.4 mm in Sangley (both intense), all at around 3 a.m. Tuesday.
“It will continue to bring moderate to heavy rain over Central and Southern Luzon, including Metro Manila, and even Western Visayas, but the rain will be isolated. By Thursday, we will have improving weather,’’ Loiz said.
The LPA, located 50 kilometers west southwest of Manila at 8 a.m., could develop into a depression while swirling away from the archipelago toward the West Philippine Sea, he said.
Ipo dam gates opened
Reaching critical level, Ipon Dam opened its gates early Tuesday to release water.
Pagasa hydrologist Sonia Serrano said in a phone interview with INQUIRER.net that as of 8 a.m. Tuesday, Ipo dam has opened 2 gates at .30 meters each.
The current water level at Ipo dam was 100.5 meters, down from 101.5 meters at 7am. Ipo dam’s high water level was at 100.8 meters.
Water levels in several riverways were nearing critical spill levels according to the National Disaster Risk Reduction and Management Council (NDRRMC) report Tuesday.
The Rosario Junction riverway had four flood gates open as of 6am, the NDRRMC said. Its currrent water level was 12.45 meters, just a few meters below the critical spill level of 13.8 meters.
The San Juan River’s water level was at 12.85, almost 1 meter above its critical spill level of 12 meters, it said.
All other riverways such as Sto. Nino, Pandacan, Angono, Montalban, and Nangka, were just below one meter of their respective spilling levels, the NDRRMC said.
Red alert on at La Mesa Dam
La Mesa Dam in Quezon City went on red alert Tuesday as water level reached 79.52 meters as of 11a.m., according to Manila Water Co. Inc., which monitors the water level in the dam.
The red alert was declared at 11:45 a.m., Manila Water communications manager Jeric Sevilla said via text message.
The water level at the reservoir increased by 4 centimeters per hour during the previous three hours with the height reaching 79.52 meters at 11 a.m., Sevilla said.
La Mesa is a spill dam, much like a giant infinity pool. The level at which water starts to overflow is 80.15 meters.
The excess water flows into the Tullahan River, which flows through the northern part of Quezon City, including the Fairview area, as well as the cities of Malabon, Valenzuela, and Caloocan. The river drains into Manila Bay.
As such, local government units or LGUs downstream of Tullahan River monitor the water levels in case households have to be evacuated due to expected flooding when La Mesa spills over amid heavy rains.
Domestic flights cancelled
Seven domestic flights from Caticlan bound for Manila and vice versa were cancelled. These were flight nos. 5J 902, 5J 911, 5J 912, 5J 905, 5J 906, 5J 915, 5J 916, NDRRMC said.
According to the media affairs division of the Manila International Airport Authority, as of 10 a.m. Tuesday, four Cebu Pacific flights to and from Naga and Busuanga were called off.
Also cancelled were two Airphil flights to and from Naga.
Work suspended
The Supreme Court, the Office of the Ombudsman and the Senate were among the first government offices to declare work suspension due to bad weather.
Acting Information Chief Atty. Gleo Guerra said work at the Court of Appeals, Sandiganbayan, Court of Tax Appeals and all lower courts in Metro Manila has suspended work at 1p.m.
The Supreme Court suspends work at 3 p.m., Guerra said.
She added that as per existing circular, provinces affected by the bad weather, work suspension will be upon the discretion of their Executive Judges.
Acting Media Information Bureau Director Edgardo Diansuy said the Ombudsman has already suspended work as per orders of Ombudsman Conchita Carpio-Morales.
Senate President Juan Ponce Enrile declared cancellation of work at Senate as early as 10 a.m.
House Secretary General Marilyn Barua-Yap at 2 p.m. Tuesday, also announced work suspension in Congress.
