Thick cloud cover and scattered rains will continue to affect several parts of the country on Saturday, January 10, due to the combined effects of multiple weather systems, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.

PAGASA weather specialist Daniel James E. Villamil said the shear line, northeast monsoon or “amihan,” and easterlies will continue to influence weather conditions across the country.

He explained that the shear line is affecting the eastern section of Southern Luzon, bringing cloudy skies with scattered rains and isolated thunderstorms. The “amihan” continues to influence most of Luzon, while easterlies prevail over the rest of the country.

“Patuloy po tayong handa at alerto sa mga banta ng flooding at landslides, lalong lalo na kung tuloy ang pag-ulan na ating mararanasan (Let us remain prepared and alert against the threats of flooding and landslides, especially if the rainfall continues),” he added.

PAGASA warned of possible flash floods and landslides, particularly in areas experiencing moderate to, at times, heavy rainfall.

In its forecast, PAGASA noted that cloudy skies with scattered rains and isolated thunderstorms are expected over Cagayan, Isabela, Quirino, Aurora, Quezon, and Rizal due to the shear line, with possible flooding or landslides.

The Bicol Region, Eastern Visayas, Dinagat Islands, and Surigao del Norte will also experience cloudy skies with scattered rains and thunderstorms caused by easterlies, which may likewise trigger flash floods or landslides.

Meanwhile, the Cordillera Administrative Region, the rest of Cagayan Valley, Nueva Ecija, and Bulacan will have cloudy skies with light rains due to the northeast monsoon, with no significant impacts expected.

Metro Manila, the Ilocos Region, and the rest of Central Luzon will experience partly cloudy to cloudy skies with isolated light rains, also due to “amihan.”

For the rest of the country, partly cloudy to cloudy skies with isolated rainshowers or thunderstorms are forecast due to easterlies, with possible flash floods or landslides during severe thunderstorms.

Villamil urged the public to remain alert and prepared, especially in flood- and landslide-prone areas, as continuous rainfall may still pose hazards.

Villamil explained that while no low-pressure area (LPA) or tropical cyclone is currently being monitored, PAGASA expects the possible formation of an LPA next week within or near the Philippine Area of Responsibility (PAR).

“As of now, wala pa naman tayong mino-monitor na LPA o anumang sama ng panahon, pero by next week, inaasahan natin na may mamuong LPA sa vicinity ng ating PAR (As of now, we are not monitoring any low-pressure area or weather disturbance; however, by next week, we expect that an LPA may develop within the vicinity of the PAR),” he explained.

“Inaasahan natin na for next week ay posibleng may mamuong low-pressure area sa ating monitoring domain within the Philippine Area of Responsibility, na maaaring mabuo at posibleng lumapit sa ating kalupaan (We expect that by next week, a possible LPA may develop within our monitoring domain inside the PAR),” Villamil said.

“Posible rin itong magdulot ng kaulapan at pag-ulan sa silangang bahagi ng Mindanao (This weather disturbance could move closer to land and may bring cloudiness and rainfall over the eastern part of Mindanao),” he added.
