Weekend/Special Farm Weather Outlook

Today (17 July): Partly cloudy to cloudy skies with isolated rainshowers or thunderstorms will prevail over Ilocos Norte, Ilocos Sur, Abra, Batanes, and Babuyan Islands due to the Southwest Monsoon (Habagat); and over the rest of the country due to localized thunderstorms.
By tomorrow to Sunday (18–19 July), the Habagat will bring cloudy skies with scattered rains and thunderstorms over Ilocos Region, Zambales, and Bataan; while the rest of the country will have fair weather conditions except for a few isolated rainshowers or thunderstorms.
By Monday (20 July), the effect of the Habagat will shift towards the western sections of Southern Luzon, Visayas, and Mindanao, thus bringing scattered rains and thunderstorms over Pangasinan, Zambales, Bataan, Cavite, Batangas, Occidental Mindoro, Palawan, Western Visayas, Negros Island Region, Zamboanga Peninsula, and BARMM. Meanwhile, the rest of the country will be partly cloudy to cloudy apart from isolated rainshowers or thunderstorms.
