MANILA, Philippines — The state-run weather agency said on Tuesday that it has been closely monitoring the movement of a low pressure area (LPA) off Northern Luzon which may either dissipate or develop into a tropical cyclone.

Weather specialist Robert Badrina of the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said the trough or extension of the LPA has been affecting Cagayan Valley, Central Luzon, Ifugao, and Benguet where cloudy skies with scattered rains and thunderstorms would prevail.

Meanwhile, the southwest monsoon or "habagat" will bring similar weather patterns over Metro Manila, Calabarzon (Cavite, Laguna, Batangas, Rizal and Quezon), Mimaropa (Mindoro, Marinduque, Romblon and Palawan), Western Visayas, Camarines Norte, and Camarines Sur.

The same weather system, Badrina said, would be experienced over Zamboanga Peninsula, Northern Mindanao, Caraga Region and the rest of Visayas where partly cloudy to overcast skies with isolated rain showers or thunderstorms would be likely, the national weather bureau said.

The rest of the country will also have the same weather conditions over the next 24 hours but due to the localized thunderstorms, the Pagasa forecaster said.
