EL SALVADOR CITY, Misamis Oriental — Widespread localized thunderstorms are expected across Mindanao over the next 24 hours, with residents in several areas warned to remain alert for possible flash floods and landslides as severe thunderstorms develop.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Mindanao Regional Services Division (MINPRSD), in its 5:00 a.m. regional weather forecast on August 31, 2026, said Mindanao will generally experience partly cloudy to cloudy skies with isolated rainshowers or localized thunderstorms from Monday morning through Tuesday morning.
The forecast is valid from 5:00 a.m. August 31 until 5:00 a.m. September 1.
PAGASA said the potential for severe thunderstorms could trigger sudden flooding and landslides, particularly in areas that receive heavy rainfall within a short period.
Residents in flood-prone, landslide-prone and low-lying communities are therefore advised to closely monitor local weather conditions and heed warnings issued by local disaster risk reduction and management offices.
‘Pilandok’ remains far from Luzon
The weather agency also continued monitoring Tropical Depression “Pilandok,” which was located far east of the Philippines.
Based on PAGASA’s available data at 3:00 p.m. on August 30, the center of Pilandok was estimated at approximately 1,215 kilometers east of Extreme Northern Luzon, near 21.0°N, 133.6°E.
The tropical depression had maximum sustained winds of 45 kilometers per hour near the center, with gustiness of up to 55 kph.
Pilandok was reported to be moving slowly northwestward.
Despite the system’s considerable distance from the country, PAGASA’s Mindanao forecast remains focused on the prevailing weather conditions affecting the region, particularly the development of localized thunderstorms.
Rainshowers possible across virtually all of Mindanao
The regional forecast indicates that no major portion of Mindanao is expected to be completely free from the possibility of rainshowers or thunderstorms.
In the Zamboanga Peninsula, Zamboanga City is forecast to experience partly cloudy to at times cloudy skies with rainshowers or thunderstorms, with temperatures ranging from 25°C to 32°C during the first forecast period and reaching as high as 35°C in the succeeding period.
Zamboanga del Norte is expected to record 25°C to 32°C, increasing to as much as 34°C, while Zamboanga del Sur may see temperatures of 25°C to 31°C, rising to 33°C.
Zamboanga Sibugay and Isabela City are both forecast to have temperatures beginning at around 24°C to 25°C, with maximum temperatures reaching 32°C to 33°C.
Across Northern Mindanao, Bukidnon is expected to remain among the cooler areas, with temperatures of 18°C to 30°C initially and up to 31°C in the succeeding period.
Camiguin may experience temperatures between 25°C and 33°C, increasing to 35°C, while Lanao del Norte may range from 21°C to 30°C, with temperatures reaching 31°C.
Misamis Occidental is forecast at 24°C to 32°C, increasing to 34°C, while Misamis Oriental may reach 33°C initially and as high as 35°C during the following period.
Davao Region also under thunderstorm watch
The Davao Region will likewise experience partly cloudy to at times cloudy skies, with rainshowers or thunderstorms possible.
Metro Davao is forecast to have temperatures ranging from 26°C to 30°C, increasing to 32°C.
Davao del Norte may see 23°C to 30°C, with maximum temperatures reaching 32°C, while Davao del Sur is expected to range from 22°C to 30°C, increasing to 31°C.
Davao Oriental is forecast to experience temperatures between 22°C and 30°C, with highs reaching 32°C.
Davao de Oro is expected to record 23°C to 33°C, with temperatures potentially reaching 35°C, while Davao Occidental may experience 23°C to 31°C, rising to 32°C.
SOCCSKSARGEN and Caraga face similar conditions
Thunderstorm activity is also expected across SOCCSKSARGEN.
North Cotabato may record temperatures of 22°C to 32°C, increasing to 34°C. South Cotabato is forecast at 22°C to 30°C, rising to 32°C, while Sultan Kudarat may range from 22°C to 31°C, reaching up to 33°C.
Sarangani is expected to experience temperatures between 25°C and 30°C, increasing to 31°C.
In Caraga, Agusan del Norte may see temperatures of 26°C to 33°C, with highs reaching 35°C. Agusan del Sur is forecast at 24°C to 32°C, rising to 34°C.
Surigao del Norte could become one of the warmer areas, with temperatures reaching as high as 36°C, while Surigao del Sur may record up to 34°C.
The Dinagat Islands are also forecast to remain warm, with temperatures ranging from 28°C to 35°C and potentially reaching 36°C.
BARMM areas also expect rain and thunderstorms
The weather pattern extends to the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).
Cotabato City is forecast to experience temperatures of 24°C to 32°C, increasing to 34°C.
Basilan may range from 24°C to 32°C, with highs reaching 33°C, while Lanao del Sur is expected to record 23°C to 30°C, increasing to 32°C.
Sulu and Tawi-Tawi are both forecast to experience temperatures beginning at 26°C, with maximum temperatures reaching 32°C to 33°C.
Maguindanao del Norte may record 24°C to 32°C, increasing to 34°C, while Maguindanao del Sur is expected to range from 24°C to 32°C, also reaching up to 34°C.
Winds generally light to moderate
PAGASA said winds across Mindanao will generally be light to moderate and coming from the south to southwest.
For coastal areas, seas are expected to remain slight to moderate, with wave heights generally ranging from 0.6 to 2.1 meters.
While these conditions do not indicate generally rough seas across the region, fishermen, small boat operators and other maritime users are still advised to consider actual local weather and sea conditions before venturing offshore, particularly when thunderstorms are developing nearby.
Residents urged to remain vigilant
With thunderstorms expected in different parts of Mindanao, PAGASA’s warning about possible flash floods and landslides remains the most immediate concern for communities.
Localized thunderstorms can produce intense rainfall over a relatively short period, potentially causing rapid rises in waterways and flooding in low-lying areas. In mountainous and elevated locations, heavy rain may also destabilize already saturated slopes.
Residents are advised to avoid crossing swollen rivers and streams, stay away from landslide-prone slopes during periods of intense rainfall, and monitor official advisories from PAGASA and local authorities.
For the latest weather information, PAGASA advised the public to monitor its official bulletins and weather updates, particularly as thunderstorm conditions can change rapidly.
The regional forecast underscores that while Tropical Depression Pilandok remains far east of Extreme Northern Luzon and is moving slowly northwestward, Mindanao’s immediate weather concern is the continued development of localized thunderstorms capable of producing heavy rain, flash floods and landslides.
