The state weather bureau has announced that Mindanao, with a specific focus on the Davao Region, will remain under the influence of easterlies throughout the week, bringing a mix of fair skies and sudden downpours.
Weather Outlook for Mindanao and Davao Region
According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), the prevailing weather system is characterized by warm and humid winds originating from the Pacific Ocean. In its 24-hour Daily Weather Bulletin issued on January 4, 2026, and valid until January 5, the agency forecasts partly cloudy to cloudy skies across most of Mindanao, punctuated by isolated rain showers or thunderstorms.
For the Davao Region, this means the provinces of Davao de Oro, Davao del Norte, Davao del Sur, Davao Occidental, and Davao Oriental, including Davao City, should prepare for brief but potentially intense weather activity. Pagasa indicated that while generally fair conditions may dominate daylight hours, localized convective activity is likely to trigger rain showers and thunderstorms, particularly during the afternoon or evening.
Potential Hazards and Public Advisories
Despite the absence of a major weather disturbance like a low-pressure area or typhoon, authorities have issued a crucial warning. The bureau cautioned that severe thunderstorms could lead to flash floods or landslides. Areas identified as highly susceptible are flood-prone communities and mountainous terrain.
"Pagasa advised residents to remain alert, noting that isolated thunderstorms may still bring short periods of heavy rainfall," the forecast emphasized. This call for vigilance extends to the entire island of Mindanao, where similar conditions are expected, and to the Caraga region, which is already experiencing cloudy skies with scattered rains due to the same easterlies.
Other Weather Systems Affecting the Philippines
Meanwhile, other parts of the archipelago are grappling with different weather patterns. The shear line is currently affecting the Visayas, Palawan, and several provinces in the Bicol Region. This system is bringing cloudy skies with scattered rains and isolated thunderstorms, with moderate to heavy rains posing risks of flash floods or landslides in these areas.
Pagasa's overarching message is for the public to closely monitor official weather updates and to heed all advisories and instructions released by local disaster risk reduction and management offices. Proactive preparation is key, especially for those living in areas historically vulnerable to flooding and landslides.
