DAVAO CITY — Tropical Storm “Ada” continues to influence weather conditions across large parts of Mindanao, triggering widespread rains, gusty winds, and rough seas, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its latest regional forecast issued at 5:00 a.m. on January 17, 2026.
PAGASA warned that the Dinagat Islands, Northern Mindanao, and the rest of the Caraga Region will bear the brunt of the storm’s effects, with moderate to at times heavy rains expected to persist until at least 5:00 a.m. tomorrow. The agency cautioned residents in these areas to be alert for possible flash floods and landslides, especially in low-lying and mountainous communities.
Dinagat Islands, Caraga Under Direct Impact
The Dinagat Islands are forecast to experience continuous rains with gusty winds due to Tropical Storm Ada. While the threat to life and property is considered minimal to minor, PAGASA stressed that strong winds and saturated ground conditions could still pose risks, particularly to coastal and upland villages.
Similarly, Agusan del Norte, Agusan del Sur, Surigao del Norte, and Surigao del Sur will have cloudy skies with scattered rains and thunderstorms, with wind speeds ranging from moderate to strong coming from the west to southwest. Coastal areas in these provinces will experience moderate to rough seas, making sea travel risky.
Northern Mindanao: Cloudy Skies, Thunderstorms Likely
In Northern Mindanao, including Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, and Misamis Oriental, residents can expect cloudy skies with rainshowers and thunderstorms. Winds will generally be light to moderate, but coastal areas—particularly in Camiguin—may experience moderate to rough sea conditions due to stronger winds.
PAGASA reiterated the possibility of flash floods and landslides in these provinces, especially during periods of heavy downpour.
Davao Region: Unsettled Weather, Isolated Thunderstorms
The Davao Region, including Metro Davao, Davao del Norte, Davao del Sur, Davao de Oro, Davao Oriental, and Davao Occidental, will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Winds are expected to be light to moderate from the west to southwest, while coastal waters will remain slight to moderate.
However, Davao Oriental’s eastern seaboard will be more exposed to stronger winds and higher waves, with moderate to rough seas forecast as TS Ada continues to enhance the southwest monsoon flow.
Zamboanga Peninsula: Mostly Fair but with Showers
Across the Zamboanga Peninsula, including Zamboanga City, Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, and Isabela City, weather conditions will be partly cloudy to at times cloudy with rainshowers or thunderstorms. Winds will be light to moderate from the northeast to northwest, and seas will be slight to moderate, generally favorable for small craft but still requiring caution.
SOCCSKSARGEN: Thunderstorms, Possible Flooding
In North Cotabato, South Cotabato, Sultan Kudarat, and Sarangani, PAGASA forecast partly cloudy to cloudy skies with rainshowers or thunderstorms. While winds will remain light to moderate, residents are advised to stay alert for localized flooding and landslides, particularly during severe thunderstorms.
BARMM: Generally Fair with Passing Rains
The Bangsamoro Autonomous Region in Muslim Mindanao (BARMM)—including Cotabato City, Basilan, Lanao del Sur, Maguindanao del Norte, Maguindanao del Sur, Sulu, and Tawi-Tawi—will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms. Winds will be light to moderate, and seas are expected to be slight to moderate.
Rough Seas, Strong Winds Along Eastern Mindanao
PAGASA emphasized that the eastern section of Mindanao will continue to experience moderate to strong winds from the west to southwest with moderate to rough seas ranging from 2.1 to 3.4 meters. Fisherfolk and operators of small seacraft are strongly advised not to venture out to sea during this period.
Meanwhile, the rest of Mindanao will have light to moderate winds from the northeast to northwest and slight to moderate seas measuring 0.6 to 2.5 meters.
Public Advised to Stay Alert
PAGASA urged local government units, disaster risk reduction offices, and the public to remain vigilant, especially in flood- and landslide-prone areas. Residents are advised to monitor official weather updates, prepare emergency kits, and avoid unnecessary travel during heavy rains.
