Mindanao, Philippines — January 31, 2026
Large portions of Mindanao are expected to experience cloudy skies, scattered rains, and thunderstorms over the next 24 hours as a shearline continues to affect the region, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its latest regional weather forecast.
In its advisory issued at 5:00 a.m. on January 31, PAGASA-Mindanao (MINPRSD) reported that the Caraga Region, along with the provinces of Davao Oriental, Camiguin, and Misamis Oriental, will experience cloudy skies with scattered rains and isolated thunderstorms due to the shearline—a weather system formed by the convergence of cold and warm air masses.
Authorities warned that moderate to heavy rains in these areas may trigger flash floods and landslides, particularly in low-lying and mountainous communities.
Eastern Mindanao Faces Rough Seas
PAGASA further noted that moderate to strong winds coming from the Northeast to Northwest will prevail over the eastern sections of Mindanao, resulting in moderate to rough sea conditions with wave heights ranging from 1.8 to 3.4 meters. Fisherfolk and operators of small sea vessels were advised to exercise caution or avoid sailing, especially along the eastern seaboards of Caraga and Davao Oriental.
Elsewhere in Mindanao, light to moderate winds from the Northeast will dominate, with slight to moderate seas measuring 0.6 to 1.8 meters.
Localized Thunderstorms in Other Areas
The rest of Mindanao—including parts of Zamboanga Peninsula, Northern Mindanao, Davao Region, SOCCSKSARGEN, and BARMM—will generally experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms caused by localized thunderstorms. PAGASA cautioned that severe thunderstorms may still lead to sudden flooding or landslides, especially during periods of intense rainfall.
