The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued its weather forecast for February 9, 2026, warning of widespread rains and potential hazards due to the combined effects of the Shear Line and the Northeast Monsoon, locally known as “Amihan.” Several areas across Luzon and the Visayas are expected to experience unstable weather conditions, which may raise concerns about flooding and landslides.
According to PAGASA, the Shear Line is currently affecting Southern Luzon and parts of the Visayas. This weather system occurs when cold winds from the northeast collide with warm easterly winds, resulting in thick cloud formations and continuous rainfall. Western Visayas, Eastern Visayas, Catanduanes, Albay, Sorsogon, and Masbate are expected to experience cloudy skies with scattered rains and isolated thunderstorms. Residents in these areas are advised to remain alert as moderate to heavy rainfall may trigger flash floods and landslides, especially in low-lying and mountainous locations.
Meanwhile, the Northeast Monsoon continues to influence much of Luzon. Areas including Cagayan Valley, the rest of the Bicol Region, Nueva Ecija, Bulacan, Aurora, Rizal, Laguna, Quezon, Oriental Mindoro, Marinduque, and Romblon will likely experience cloudy skies with occasional rains. PAGASA warns that prolonged rainfall in these areas may lead to localized flooding and landslides. The Cordillera Administrative Region will also experience cloudy skies with light rains, but with no significant impact expected.
Metro Manila and the rest of Luzon are forecast to have partly cloudy to cloudy skies with isolated light rains. While no major hazards are anticipated in these areas, residents are still advised to stay informed about sudden weather changes. Meanwhile, the rest of the country may experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms caused by localized weather disturbances. Severe thunderstorms may still pose risks of flash floods or landslides.
PAGASA has also issued Heavy Rainfall Warning No. 3 for parts of the Visayas under the influence of the Shear Line. An Orange Warning is currently in effect over several municipalities in Samar and Eastern Samar, including Gandara, Calbayog City, Tarangnan, Jipapad, and Maslog. Under this warning level, flooding is considered threatening in low-lying areas, while landslides remain possible in mountainous locations.
A Yellow Warning has also been raised in parts of Negros Occidental, Iloilo, Capiz, Aklan, Samar, Eastern Samar, and Guimaras. Flooding remains possible in vulnerable communities, and residents are urged to monitor weather updates and follow safety advisories issued by authorities.
In terms of wind and coastal conditions, strong to gale-force winds are expected over Northern Luzon, Central Luzon, and the eastern sections of Southern Luzon and the Visayas. Coastal waters in these areas may become rough to very rough, with wave heights reaching up to 5.5 meters. Fisherfolk and small sea vessel operators are strongly advised to avoid sailing due to dangerous sea conditions. The rest of Luzon may experience moderate to strong winds with moderate to rough seas, while the rest of the country will have relatively calmer conditions.
PAGASA has also released General Flood Advisories covering several regions, including Central Luzon, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, Eastern Visayas, Northern Mindanao, and CARAGA. Residents in flood-prone areas are encouraged to remain vigilant, prepare emergency supplies, and coordinate with local disaster response units as necessary.
Authorities continue to monitor the evolving weather systems and urge the public to stay informed through official PAGASA bulletins and local government announcements to ensure safety and preparedness.
