MANILA, Philippines – July 17, 2025. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued its latest 5 PM advisory on Tropical Cyclone Crising, warning of widespread heavy rainfall over several parts of the country from today until Sunday, July 20. The effects of Crising are further intensified by the southwest monsoon (habagat), which is expected to bring torrential rains across Luzon, Visayas, and parts of Mindanao.
Heavy Rainfall Outlook: July 17 to 18
From today until tomorrow afternoon, areas expected to receive over 200 mm of rainfall include Cagayan, Isabela, and Catanduanes. Rainfall ranging from 100-200 mm is forecast in Apayao, Kalinga, Quirino, Aurora, Quezon, Camarines Norte, and Camarines Sur. Meanwhile, 50-100 mm of rain is likely to affect Ilocos Norte, La Union, Pangasinan, and several Bicol and Eastern Visayas provinces.
Rainfall Forecast: July 18 to 19
By tomorrow afternoon until Saturday, the heaviest rains exceeding 200 mm are projected in Apayao and Ilocos Norte. Moderate to heavy rainfall of 100-200 mm will hit Cagayan, Kalinga, Abra, Benguet, and nearby provinces, while Ifugao, Isabela, and Nueva Vizcaya will likely experience 50-100 mm of rain.
Rainfall Forecast: July 19 to 20
From Saturday afternoon to Sunday afternoon, Ilocos Norte and Ilocos Sur will continue to receive 50-100 mm of rain.
Southwest Monsoon Impact
PAGASA also notes significant monsoon rains affecting western sections of the country. From today to July 18, Palawan, Occidental Mindoro, Iloilo, Guimaras, Antique, and Negros Occidental may receive 100-200 mm of rainfall. Metro Manila and surrounding provinces could see 50-100 mm, prompting possible localized flooding.
By July 19, Zambales, Bataan, and Batangas will be under increased risk due to sustained monsoon rains. The downpour continues into July 20, especially in Zambales, Bataan, and Occidental Mindoro, with 100-200 mm expected.
Flood Advisories and Precautionary Measures
PAGASA has issued General Flood Advisories (GFAs) for 14 regions, including the Cordillera Administrative Region (CAR), Ilocos Region, Cagayan Valley, Central Luzon, CALABARZON, MIMAROPA, Bicol Region, Western and Central Visayas, and parts of Mindanao, including BARMM and Northern Mindanao.
Residents are strongly urged to remain alert for Heavy Rainfall Warnings, which are precise, short-term advisories based on Doppler radar data and localized within municipalities. These differ from broader Weather Advisories, which provide 24-hour guidance but are less specific.
