Mindanao residents can expect another warm yet potentially stormy day as the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecasts partly cloudy to cloudy skies across the region, with isolated rainshowers or thunderstorms triggered by the prevailing Easterlies. The weather bureau issued the advisory early Thursday morning, warning communities to stay alert for possible flash floods or landslides, especially during severe thunderstorms.
Throughout Mindanao, light to moderate winds blowing from the northeast will prevail, resulting in slight to moderate coastal seas ranging from 0.6 to 2.1 meters. Afternoon and evening thunderstorms remain a common threat, a pattern observed for the past several days due to warm and moist air from the east.
ZAMBOANGA PENINSULA: Warm Conditions With Periodic Storm Clouds
Zamboanga City and the provinces of Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, and Isabela City are forecast to experience partly cloudy to at times cloudy skies, with intermittent rainshowers and thunderstorms.
Temperatures are expected to range between 23°C and 33°C, depending on the location and time of day.
Coastal waters will remain slight to moderate, favorable for small fishing boats, although PAGASA urges caution during thunderstorms.
NORTHERN MINDANAO: Slight Cooling at Night, Possible Heavy Rains
Provincial areas including Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, and Misamis Oriental will see similar conditions, with partly cloudy weather in the morning giving way to cloud buildup and isolated thunderstorms later in the day.
Bukidnon will record cooler temperatures at night, dropping to 19°C, while coastal areas in the region maintain slightly warmer conditions at 24–31°C.
DAVAO REGION: Consistent Thunderstorm Pattern
Metro Davao, Davao del Norte, Davao del Sur, Davao Oriental, Davao de Oro, and Davao Occidental are all expected to experience periodic thunderstorms, particularly in the afternoon and evening.
Davao Oriental may record the highest daytime temperature at 34°C, while most of the region will range from 24°C to 33°C.
Northeasterly winds will keep seas slight to moderate, suitable for sea travel but with precautions during storm occurrences.
SOCCSKSARGEN: Warm but Unstable Weather
In North Cotabato, South Cotabato, Sultan Kudarat, and Sarangani, skies will be partly cloudy with anticipated brief but potentially intense rainshowers.
Daytime temperatures are forecast between 22°C and 33°C, with cooling evening conditions.
Coastal waters remain manageable, but PAGASA continues to remind coastal communities to stay updated on thunderstorm advisories.
CARAGA REGION: Cloudy Skies and Afternoon Downpours
Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands residents may experience cloudy skies with isolated thunderstorms, especially during the late afternoon.
Temperatures will range from 24°C to 32°C, while sea conditions stay at slight to moderate levels.
BARMM: Persistent Easterlies Bring Heat and Humidity
Across the Bangsamoro region—including Cotabato City, Basilan, Lanao del Sur, Sulu, Tawi-Tawi, Maguindanao del Norte, and Maguindanao del Sur—PAGASA reports similar weather patterns with isolated thunderstorms possible throughout the day.
Coastal provinces such as Sulu and Tawi-Tawi may experience slightly higher temperatures of 26°C to 32°C, while upland areas in Lanao del Sur may cool down to 21°C overnight.
PUBLIC REMINDERS
PAGASA emphasizes vigilance among communities living near rivers, steep slopes, and low-lying areas due to the increased threat of flash floods and landslides during severe thunderstorms.
Fisherfolk and small vessels are advised to monitor local updates as sea conditions may quickly worsen during sudden downpours. Meanwhile, the public is urged to stay hydrated and avoid prolonged sun exposure during midday when temperatures peak.
