The southwest monsoon will remain the dominant weather system over parts of the country through Wednesday, bringing periods of rain and raising the risk of flooding and landslides in several areas, PAGASA said.
Zambales, Bataan, Batangas and Occidental Mindoro face the heaviest monsoon rains Monday, with the weather bureau projecting 50 to 100 millimeters of rainfall over a 24-hour period.
Communities in low-lying and highly urbanized locations were advised to watch for localized flooding, while residents of landslide-prone areas should remain alert as prolonged rainfall could increase hazards.
Metro Manila will also remain under unsettled weather, along with the Ilocos Region, Abra, Benguet, much of Central Luzon, Calabarzon and Mimaropa. These areas may experience scattered showers and thunderstorms under cloudy skies.
In the Visayas, Antique will have similar monsoon-driven conditions. Elsewhere in the Visayas and across Mindanao, thunderstorms may produce isolated rain showers during the day.
Tropical Storm Pilandok, internationally called Krovanh, continues to reinforce the southwest monsoon from outside the Philippine area of responsibility. Pagasa said the cyclone was unlikely to cross back into PAR.
Despite the persistent rains, PAGASA had not issued a gale warning for any Philippine seaboard. Temperatures in Metro Manila were forecast between 25°C and 31°C, while Baguio could range from 17°C to 20°C.
The monsoon is expected to continue influencing Philippine weather until Wednesday, extending the wet spell particularly across western sections of Luzon even without a direct impact from Pilandok.
