The Philippine Atmospheric, Geophysical, and Astronomical Services Administration issued this afternoon a form stating the commencement of flood precaution period for four river basins in Luzon due to a low-pressure area east of the country.


The Flood Warning Operation (FWO) Form No. 1, which was signed by PAGASA Hydrometeorology Division chief Roy Badilla, informs that the bureau has commenced the Flood Precaution Period of the Dam Discharge Warning Operation for the Angat, Magat, Pantabangan, and San Roque River basins because of an active low-pressure area.

PAGASA issued the FWO to the concerned flood operation managers, Provincial Disaster Risk Reduction and Management Councils, and chief meteorological officers.

“We request your organization to acknowledge the commencement of the Flood Precaution Period of the Dam Discharge Warning Operation immediately and to be ready to receive further information,” PAGASA said.

As of 3 p.m., PAGASA estimated the location of the LPA at 265 kilometers east of Infanta, Quezon.

PAGASA said the LPA may bring cloudy skies with scattered rain showers and thunderstorms over Aurora, Quirino, and Isabela.

The public is advised to take precautionary measures against possible flash floods or landslides due to the anticipated moderate to at times heavy rains.
Meanwhile, the northeast monsoon or “amihan” may continue to bring cloudy skies with light rains over Kalinga, Apayao, Mountain Province, Ifugao, Batanes, Cagayan, and Nueva Vizcaya.

Partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the warm and humid easterly winds may also affect Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, Masbate, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Visayas, and Mindanao.

The amihan may also bring partly cloudy to cloudy skies with isolated light rains over Metro Manila and the rest of Luzon.

A gale warning remains in effect on Thursday afternoon due to the surge of northeast monsoon.

PAGASA said strong to gale force winds are expected to affect the northern and eastern seaboards of Northern Luzon, eastern seaboards of Central and Southern Luzon, and western seaboard of Northern Luzon.

As rough to very rough seas may prevail over these coasts, PAGASA advised fishing boats and other small boats not to venture out into the sea while larger sea vessels were asked to remain alert against big waves.
