EL SALVADOR CITY, Misamis Oriental — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has warned residents across large parts of Mindanao to brace for cloudy skies with scattered rain showers and thunderstorms throughout the day, October 31, 2025, due to the continued effect of the Intertropical Convergence Zone (ITCZ).
According to PAGASA’s Mindanao Regional Services Division (MINPRSD), the Zamboanga Peninsula, Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), SOCCSKSARGEN, Davao Region, and Lanao del Norte will experience cloudy skies with scattered rains and thunderstorms. These weather conditions may bring moderate to at times heavy rainfall, increasing the risk of flash floods and landslides, especially in low-lying and mountainous areas.
The rest of Mindanao will have partly cloudy to cloudy skies with isolated rain showers and thunderstorms, still due to the ITCZ. PAGASA cautioned that severe thunderstorms could also trigger localized flooding or landslides.

Weather Outlook and Safety Advisory
The ITCZ, often referred to as the “rain belt” of the tropics, continues to dominate the southern Philippines’ weather pattern. PAGASA advised the public, especially those living near rivers, streams, and mountain slopes, to stay vigilant and monitor official weather bulletins for updates. Fisherfolk and small seacraft operators are also advised to take caution due to possible rough sea conditions during thunderstorms.
Residents are encouraged to keep emergency kits ready and avoid crossing swollen rivers or flooded roads. Local Disaster Risk Reduction and Management Councils (DRRMCs) are urged to remain on standby for potential evacuation operations should conditions worsen.
