DAVAO CITY, Philippines — A Shear Line continues to affect large portions of Mindanao, bringing cloudy skies, scattered rains, and isolated thunderstorms, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) in its Regional Weather Forecast for Mindanao (MINPRSD) issued at 5:00 a.m. on January 26, 2026.
PAGASA said the weather system is directly influencing the Caraga Region, Davao Region, Camiguin, and Misamis Oriental, where moderate to at times heavy rainfall is expected until 5:00 a.m. tomorrow. Authorities warned that these conditions could trigger flash floods and landslides, especially in low-lying areas, river basins, and mountainous communities.
Areas Under the Shear Line
Provinces in Caraga—including Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands—will experience cloudy skies with rainshowers and thunderstorms, accompanied by strong northeast to north winds. Coastal waters in these areas are expected to be rough, with wave heights reaching 2.8 to 4.0 meters, posing risks to small sea vessels.
In the Davao Region, including Metro Davao, Davao del Norte, Davao del Sur, Davao Oriental, Davao de Oro, and Davao Occidental, weather conditions are forecast to range from partly cloudy to cloudy, with frequent rainshowers and thunderstorms. Strong northeast winds will prevail, while coastal waters remain rough, prompting advisories for fisherfolk and operators of small boats.
Camiguin and Misamis Oriental will also see cloudy skies with persistent rainshowers and thunderstorms, with moderate to strong northeast winds and moderate to rough seas.
Rest of Mindanao: Localized Thunderstorms
Meanwhile, the rest of Mindanao, including Zamboanga Peninsula, Northern Mindanao provinces outside the shear line, SOCCSKSARGEN, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms due to localized thunderstorms.
Provinces such as Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, Isabela City, Bukidnon, Lanao del Norte, North Cotabato, South Cotabato, Sultan Kudarat, Sarangani, Basilan, Maguindanao del Norte, Maguindanao del Sur, Sulu, and Tawi-Tawi are expected to have moderate to strong northeast winds and moderate to rough coastal conditions, with temperatures ranging from 18°C to 35°C, depending on location.
Sea Travel and Public Safety Advisory
PAGASA emphasized that strong winds from the northeast to north will dominate the eastern sections of Mindanao, resulting in dangerous sea conditions, while the rest of the island will experience moderate to strong winds and moderate to rough seas.
The weather bureau advised:
- Fisherfolk and small vessel operators to avoid sailing in affected coastal waters
- Local disaster risk reduction offices to remain on alert for possible flooding and landslides
- Residents in mountainous and flood-prone areas to take precautionary measures
PAGASA forecasters CTA and EBZ said weather conditions may still change and urged the public to monitor official bulletins.
