By Ellalyn de Vera-Ruiz The effect of the tail-end of cold front has already weakened however the surge of northeast monsoon or “amihan” may continue to bring light rains over Cagayan Valley, Cordillera Administrative Region, Ilocos Norte, and Ilocos Sur. (PAGASA/ MANILA BULLETIN) Cagayan and other parts of Northern Luzon has been hit by massive flooding due to monsoon rains intensified by the passage of typhoon “Tisoy” (international name “Kammuri”) this week. The tail-end of cold front, a weather system where warm and cold air meets, may no longer affect the country this Sunday. However, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the “amihan” may bring light rains over Batanes, Cagayan, Isabela, Nueva Vizcaya, Quirino, Abra, Benguet, Ifugao, Kalinga, Mountain Province, Apayao, Ilocos Norte, and Ilocos Sur this Sunday. Likewise, Metro Manila and the rest of Luzon, except Palawan will have partly cloudy to cloudy skies with isolated light rains from the “amihan.” PAGASA weather forecaster Aldczar Aurelio said the whole Luzon may also feel colder weather, especially in the early morning, due to the surge of “amihan.” Palawan, Visayas, and Mindanao may experience partly cloudy to cloudy skies with isolated rain showers due to localized thunderstorms. Aurelio said the tail-end of cold front will likely re-intensify by Monday and may bring rains and thunderstorms over Bicol Region and Eastern Visayas. Meanwhile, a gale warning is still in effect as sea travel remains risky for small sea crafts over the coasts of Batanes, Cagayan, Babuyan Islands, Isabela, Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Zambales, Aurora, Bataan, Polilio Islands, Camarines Norte, northern and eastern Camarines Sur, Palawan, and Catanduanes.
