Moderate to heavy rains will likely persist over southern Luzon, Bicol region, Visayas, and Mindanao on Tuesday, Feb. 9, due to the prevalence of the trough or extension of a low pressure area (LPA) inside the country’s area of responsibility.

Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Chris Perez said the LPA was estimated at 175 kilometers east of Davao City, Davao del Sur around 3 p.m.

Perez said cloudy skies and scattered moderate to heavy rains and thunderstorms due to the trough of LPA may affect southern Quezon, Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, Masbate, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Visayas, and Mindanao.

Flooding, including flash floods, and rain-induced landslides may occur during heavy or prolonged periods of rainfall, especially in areas that are highly susceptible to these hazards, PAGASA warned.

Meanwhile, the northeast monsoon or “amihan” may bring light rains over Batanes, Cagayan, Isabela, Quirino, Nueva Vizcaya, Abra, Apayao, Benguet, Ifugao, Kalinga, and Mountain Province.

Isolated light amihan rains may also affect Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Bulacan, Pampanga, Tarlac, Bataan, Zambales, Nueva Ecija, and Aurora. 

The rest of the country, including Metro Manila, will have “fair” weather due to partly cloudy to cloudy skies and isolated rain showers caused by localized thunderstorms.

PAGASA warned the public against severe thunderstorms that could trigger flash floods in low-lying areas or landslides in mountainous communities. 

Perez said PAGASA has raised a gale warning on Monday afternoon, Feb. 8, due to strong gale force winds associated with the surge of amihan.

The northern and western seaboards of Northern Luzon, particularly Batanes, Calayan, Babuyan, Ilocos Norte, and northern coast of Cagayan, will be rough to very rough.

Fishing boats and other small sea vessels were advised to prevent from travelling out to sea, while larger sea vessels were asked to remain alert against big waves due to risky sea travel over these waters. 

Perez said slight to moderate seas are expected over the rest of the archipelago, unless severe offshore thunderstorms accompanied by strong winds occur that may cause big waves.
