The low-pressure area (LPA) spotted near Palawan has a low chance of developing into a tropical cyclone, but rains will continue to affect several areas due to various weather systems, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Wednesday, Feb. 12.

PAGASA Weather Specialist Obet Badrina said the LPA, located 260 kilometers west-northwest of Pag-asa Island, Kalayaan, Palawan, is expected to remain outside the country’s area of responsibility.

The chance of the LPA developing into a tropical cyclone is low as it moves toward Vietnam.

However, Badrina said the LPA’s trough or extension is affecting the southern portion of Palawan, bringing scattered rains and thunderstorms.

He added that, due to the prevalence of other weather systems, there is still a high chance of rain over a large part of the country in the next 24 hours

Cloudy skies with scattered rains and isolated thunderstorms may affect Isabela, Aurora, and Quezon due to the shear line—a weather system formed by the collision of cold winds from the northeast monsoon (amihan) and warm breezes from the Pacific Ocean (easterlies).

Scattered rains and thunderstorms may also persist in Mindanao due to the easterlies.

The Cordillera Administrative Region and the rest of Cagayan Valley will experience cloudy skies and rains due to the amihan.

PAGASA warned residents affected by the four weather systems to remain vigilant for possible flash floods or landslides during moderate to heavy rainfall.

The Ilocos Region and the rest of Central Luzon will experience partly cloudy to cloudy skies with isolated light rains due to the amihan, while the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the easterlies.
