PAGASA warns of possible flash floods, landslides amid thunderstorms
December 1, 2025 — Mindanao. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued a regional weather advisory at 5:00 a.m. today, warning of continued rains across Mindanao as the Intertropical Convergence Zone (ITCZ) affects large parts of the region.
According to PAGASA–Mindanao PRSD, the Caraga and Davao regions will experience cloudy skies with scattered rainshowers and thunderstorms throughout the day, with the likelihood of moderate to at times heavy rainfall. Residents, particularly those in low-lying and mountainous areas, are cautioned against possible flash floods and landslides.
Meanwhile, the rest of Mindanao—including provinces in Zamboanga Peninsula, Northern Mindanao, SOCCSKSARGEN, and the Bangsamoro Autonomous Region—will have partly cloudy to cloudy skies with isolated rainshowers and thunderstorms, also due to the ITCZ. PAGASA noted that thunderstorms may trigger localized intense rainfall, prompting similar hazards.
