MANILA, Philippines - Weather bureau PAGASA continues to keep a close watch on an active low pressure area (LPA) that was last spotted around 890 kilometers east of Borongan, Eastern Samar on Monday afternoon.
The weather system may gain strength and become a storm, PAGASA warned.
The LPA may also pull and enhance the southwest monsoon, which is mostly affecting the western section of the country.
Northern and southern Luzon will be partly cloudy to cloudy with isolated rainshowers or thunderstorms, while central and southern Luzon will have mostly cloudy skies with scattered rainshowers and thunderstorms, becoming cloudy with widespread rains over the Bicol region.
Moderate to strong winds blowing from the southwest will prevail over northern and central Luzon, and coastal waters along these areas will be moderate to rough, PAGASA said.
Meanwhile, Metro Manila is expected to continue to have thick cloud cover and has an 80% chance of getting light to moderate showers up to around 9 p.m. Monday.
The rest of the country, particularly Cebu, Bacolod, and Boracay, as well as the rest of the central islands will stay cloudy with a 90% chance for rains Monday night.
Mindanao will be cloudy with scattered rainshowers. - ANC
