Scattered rain showers may prevail across the western section of the country and extreme Northern Luzon due to the lingering southwest monsoon and frontal system over the country on Tuesday.
In its 5 a.m. weather bulletin, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said the southwest monsoon or "habagat" will bring cloudy skies and scattered rain showers and thunderstorms over Palawan, Occidental Mindoro, Aklan, Antique, Capiz, Guimaras, Iloilo, Negros Occidental, Sulu, Basilan, Zamboanga Sibugay, Zamboanga del Norte, and Zamboanga del Sur.
Scattered rain showers and thunderstorms may also affect Batanes and Babuyan Islands due to the frontal system or the boundary between warm and cold air masses.
Metro Manila and the rest of the country will remain partly cloudy to cloudy with a high chance of having isolated afternoon or evening rain showers or thunderstorms brought by the "habagat" and localized thunderstorm activity.
Due to the possibility of heavy rain showers during severe thunderstorms, PAGASA advised the public to take necessary precautionary measures in case of flooding or landslides.
Weather specialist Aldczar Aurelio said a tropical depression was monitored at 2,570 kilometers east of extreme Northern Luzon, but remains too far to affect the Philippines.
It also has a slim chance of entering the Philippine area of responsibility.
Meanwhile, PAGASA has not issued a gale warning on Tuesday as slight to moderate sea conditions will persist across the country's seaboards.
Fisherfolk and those using small boats are safe to sail but are still advised to take precaution when venturing out to sea.
