Rain-bearing weather systems, including a possible low pressure area (LPA), may bring rainy condition over a huge portion of the country towards the weekend, according to a weather forecaster.

Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Benison Estareja said a cloud cluster was monitored outside the Philippine area of responsibility (PAR) or near the southern part of Guam on Tuesday afternoon.

He said it is possible that an LPA will form from this cloud cluster while off the east coast of Mindanao as early as Thursday or Friday. 

“It will move west-northwest towards northern Mindanao-southern Visayas area, then afterwards, it will move over the Sulu Sea until it reaches the West Philippine Sea by Sunday,” Estareja said.

The potential LPA is less likely to intensify into a tropical depression as of the moment, he added.

However, Estareja said it will likely be rainy in the coming days due to the LPA, as well as the combined effects of the tail-end of frontal system, northeast monsoon or “amihan,” and easterlies.

He advised those planning to go outside to bring an umbrella.

This Wednesday, PAGASA said the northeast monsoon may continue to bring cloudy skies with light rains over Batanes and Babuyan Islands, partly cloudy to cloudy skies with isolated light rains over Ilocos Norte, Ilocos Sur, La Union, and Pangasinan.

Metro Manila and the rest of the country, except Cordillera Administrative Region, Cagayan Valley, and Aurora, will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the easterlies, or the warm and humid winds coming from the Pacific Ocean.

PAGASA said the tail-end of frontal system, which is the boundary between cold amihan and warm easterlies, may bring scattered light to moderate to at times heavy rains during thunderstorms over Cagayan, Isabela, Quirino, Nueva Vizcaya, Abra, Apayao, Benguet, Ifugao, Kalinga, Mountain Province, and Aurora.

The weather bureau advised the public to take necessary precautions against possible flash floods or landslides that may occur in areas that may be affected by the tail-end of frontal system and easterlies.

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

PAGASA said strong to gale force winds are expected to affect the eastern, northern, and western seaboards 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. 

The rest of the country’s seas will have slight to moderate conditions.
