MINDANAO — Most parts of Mindanao are expected to experience partly cloudy to cloudy skies with isolated rain showers or localized thunderstorms over the next 24 hours, according to the regional weather forecast issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Mindanao Regional Services Division (MINPRSD).
The forecast, issued at 5:00 a.m. on August 24, 2026, is valid until 5:00 a.m. on August 25. PAGASA identified localized thunderstorms affecting Mindanao as the prevailing weather condition across the region.
While generally partly cloudy conditions are expected, thunderstorms may develop in various areas and could bring sudden heavy rainfall. PAGASA warned that flash floods and landslides are possible, particularly in areas affected by severe thunderstorms.
Residents in flood-prone communities, landslide-susceptible areas and locations near rivers and waterways are advised to remain alert for rapidly changing weather conditions, particularly when thunderstorms intensify.
Light to moderate winds, manageable seas
Winds across Mindanao are expected to remain light to moderate, generally coming from the south to southwest.
Coastal waters are forecast to be slight to moderate, with wave heights ranging from approximately 0.6 to 2.1 meters.
The conditions may still affect small fishing boats and other small sea vessels, particularly during thunderstorms when winds and waves can suddenly become stronger than prevailing conditions.
Weather outlook across Mindanao
In the Zamboanga Peninsula, Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay and Isabela City are expected to experience partly cloudy to at times cloudy skies with rain showers or thunderstorms.
Temperatures in the area are generally expected to range from 24°C to 34°C, depending on the province and forecast period.
Across Northern Mindanao, Bukidnon is expected to have temperatures between 20°C and 31°C, while Camiguin may reach 33°C. Lanao del Norte is forecast to be cooler, with temperatures ranging from 21°C to 30°C, while Misamis Occidental may reach 32°C. Misamis Oriental could see temperatures rise to as high as 35°C during the daytime period.
The Davao Region will likewise remain under the possibility of isolated rain showers or thunderstorms. Metro Davao is forecast to experience temperatures of 26°C to 33°C, while Davao del Norte could reach 34°C. Davao del Sur may see temperatures between 23°C and 34°C, Davao Oriental between 22°C and 32°C, Davao de Oro between 23°C and 33°C, and Davao Occidental between 26°C and 32°C.
In SOCCSKSARGEN, North Cotabato is expected to range from 24°C to 33°C, South Cotabato from 23°C to 32°C, Sultan Kudarat from 22°C to 33°C, and Sarangani from 25°C to 33°C.
The Caraga Region will also remain prone to rain showers and thunderstorms. Agusan del Norte is forecast to reach 35°C, while Agusan del Sur may reach 34°C. Surigao del Norte is expected to range from 25°C to 35°C, Surigao del Sur from 25°C to 36°C, and Dinagat Islands from 27°C to 35°C.
BARMM also under thunderstorm watch
Areas across the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) are likewise expected to experience similar conditions.
Cotabato City may see temperatures between 23°C and 34°C, while Basilan is forecast to range from 24°C to 33°C.
Lanao del Sur is expected to have temperatures of 23°C to 31°C, while Sulu and Tawi-Tawi may reach 33°C.
Maguindanao del Norte is forecast to reach as high as 35°C, while Maguindanao del Sur could also reach 35°C during the daytime period.
Despite the relatively warm temperatures in many areas, the development of thunderstorms could result in sudden changes in local weather, including intense rainfall and gusty winds.
Three tropical cyclones outside the Philippine Area of Responsibility
PAGASA also reported three tropical cyclone systems outside the Philippine Area of Responsibility (PAR) in its latest regional forecast.
Typhoon Saudel (2618) was located approximately 1,950 kilometers east of extreme Northern Luzon, near 22.0°N, 140.7°E. It had maximum sustained winds of 165 kilometers per hour near the center, with gustiness reaching 205 kilometers per hour, and was moving northwestward at 30 kilometers per hour.
A tropical depression was located approximately 1,265 kilometers east of southeastern Luzon, near 13.4°N, 135.9°E. It had maximum sustained winds of 55 kilometers per hour, gustiness of up to 70 kilometers per hour, and was moving east-northeastward at 15 kilometers per hour.
Meanwhile, Tropical Depression Gaenari (2620), formerly known as “Neneng,” was located around 520 kilometers north of Itbayat, Batanes, near 25.4°N, 120.9°E. It was packing maximum sustained winds of 55 kilometers per hour, with gustiness reaching 70 kilometers per hour, and was moving southwestward at 25 kilometers per hour.
These systems were reported outside the PAR in the regional forecast. The prevailing weather over Mindanao, however, is attributed to localized thunderstorms.
PAGASA urges vigilance
With thunderstorms capable of producing sudden heavy rain, residents are urged to monitor official weather advisories and remain prepared for rapidly changing conditions.
Communities located near rivers, creeks, steep slopes and other hazard-prone areas should exercise caution when thunderstorms occur, as intense rainfall over a short period can trigger flash floods or landslides.
Motorists are also advised to exercise extra caution during heavy downpours because reduced visibility, slippery roads and sudden flooding may create hazardous travel conditions.
For the latest weather information and advisories, PAGASA urged the public to monitor official updates and weather bulletins.
