DAVAO CITY, Philippines — Residents across Northern Mindanao, Caraga, and the Davao Region should prepare for cloudy skies, scattered rain showers, and thunderstorms over the next 24 hours as the Intertropical Convergence Zone (ITCZ) continues to affect the northern and eastern sections of Mindanao, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its Regional Weather Forecast issued at 5:00 a.m. on June 27, PAGASA said the ITCZ will bring moderate to at times heavy rainfall, raising the risk of flash floods and landslides, particularly in low-lying communities, mountainous areas, and locations with saturated soil.
The weather advisory remains valid until 5:00 a.m. on June 28.

Meanwhile, the rest of Mindanao—including Zamboanga Peninsula, SOCCSKSARGEN, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM)—will generally experience partly cloudy to cloudy skies with isolated rain showers or localized thunderstorms.
Although rainfall is expected to be less widespread in these areas, PAGASA cautioned that severe localized thunderstorms could still trigger flash floods and landslides, particularly in flood-prone and mountainous communities.

Light to Moderate Winds, Calm to Moderate Seas
Across Mindanao, winds are expected to remain light to moderate, blowing from the southwest to west.
Coastal waters throughout the island are forecast to be slight to moderate, with wave heights ranging from 0.6 to 1.5 meters, making sea travel generally manageable. However, PAGASA advised fishermen and operators of small sea vessels to remain cautious, particularly when thunderstorms develop over coastal waters.
Temperatures Across Mindanao
Forecast temperatures remain relatively warm despite the rainy conditions.
Among the warmest areas are:
- Surigao del Norte: 27°C to 35°C
- Zamboanga City: up to 35°C
- Camiguin: up to 33°C
- Metro Davao: up to 33°C
Cooler temperatures are expected in higher elevation areas such as Bukidnon, where temperatures may range between 21°C and 29°C, while most provinces across Mindanao will experience daytime highs between 29°C and 32°C.
Public Advised to Stay Alert
PAGASA urged the public to continue monitoring official weather advisories, particularly residents living in flood-prone communities, near rivers, and in landslide-susceptible areas.
Motorists are advised to exercise caution on slippery roads during heavy downpours, while local disaster risk reduction and management offices are encouraged to remain vigilant and ready for any weather-related emergencies as the ITCZ continues to influence weather conditions over much of Mindanao.
