El Salvador City, Misamis Oriental – August 28, 2025 — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned Mindanao residents to brace for unsettled weather today as the southwest monsoon continues to bring scattered rains and thunderstorms, particularly over Zamboanga Peninsula, Northern Mindanao, and Caraga Region.
At 3:00 a.m., a Low Pressure Area (LPA) was spotted 435 kilometers west of Sangley Point, Cavite City. While the LPA remains outside the Philippine Area of Responsibility (PAR), its presence enhances the southwest monsoon or habagat, pulling more moisture into the southern and western parts of the country.
Rain-affected provinces
According to PAGASA’s Mindanao regional forecast, provinces in Zamboanga Peninsula—including Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, and Isabela City—will experience cloudy skies with rainshowers and thunderstorms throughout the day and night. Coastal waters across the region are expected to remain slight to moderate, with sea heights ranging from 0.6 to 1.5 meters.
Similar weather conditions are expected across Northern Mindanao, including Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, and Misamis Oriental. Rain showers and thunderstorms may be intense at times, raising the possibility of flash floods and landslides, especially in low-lying and mountainous areas.
In Caraga, the provinces of Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands will also see persistent rains and thunderstorms. Surigao provinces in particular are forecasted to experience daytime temperatures peaking at 31–33°C, which may intensify thunderstorm activity in the afternoon.
Fairer skies in other regions
Meanwhile, relatively calmer weather is expected in the Davao Region, SOCCSKSARGEN, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM). Metro Davao, North Cotabato, South Cotabato, Sultan Kudarat, Sarangani, and Cotabato City are forecast to have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Temperatures will hover between 23°C to 32°C, with light to moderate winds coming mostly from the southwest to west.
In the island provinces of Basilan, Sulu, and Tawi-Tawi, as well as in Lanao del Sur, Maguindanao del Norte, and Maguindanao del Sur, fair weather is expected for most of the day, but residents are cautioned against sudden downpours and thunderstorms in the late afternoon or evening.
Public advisory
PAGASA urged the public to remain vigilant as moderate to heavy rains brought by the southwest monsoon could trigger flooding in low-lying areas and landslides in upland communities. Fisherfolk and small seacraft are advised to take caution as sea conditions, although generally slight to moderate, may worsen during thunderstorms.
The agency also reminded residents to monitor updates from local disaster risk reduction offices and continue tracking advisories from PAGASA through its official website and hotlines.
