Cold and rainy weather due to the northeast monsoon or “amihan” may prevail over Cordillera Administrative Region, Ilocos Region, and parts of Central Luzon and Cagayan Valley on Wednesday.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Abra, Apayao, Benguet Ifugao, Kalinga, Mountain Province, Batanes, Cagayan, Isabela, Tarlac, Pampanga, Zambales, and Bataan will be cloudy and rainy caused by the northeast monsoon.
Partly cloudy to cloudy skies with isolated light rains may also be felt in Ilocos Norte, Ilocos Sur, La Union, and Pangasinan.
The tail-end of frontal system, which is the convergence of cold air coming from the amihan and warm air coming from the easterlies, may also bring cloudy skies with scattered rain showers and thunderstorms over Nueva Vizcaya, Quirino, Aurora, Nueva Ecija, Bulacan, Rizal, and Quezon.
PAGASA warned those in areas affected by the tail-end of frontal system to stay vigilant against possible flash floods or landslides due to the occurrence of moderate to at times heavy rains.
Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers caused by localized thunderstorms.
PAGASA also advised the public against possible floods or landslides during a severe thunderstorm activity.
The weather bureau has not issued a gale warning on Monday as sea conditions over Northern Luzon and the eastern section of Central Luzon will be moderate to rough, while it will be slight to moderate over the rest of the country
