Rains will be concentrated over Eastern Visayas and the Bicol Region where cloudy skies with light to moderate rain showers and thunderstorms are expected. These rains are brought by the diffused tail end of a cold front, a weather system that occurs when the cold air mass dominates the warm air mass during convergence. Meanwhile, the northeast monsoon or amihan continues to blow through Northern and Central Luzon.
Cagayan Valley, Cordillera, and the provinces of Aurora and Quezon will have cloudy skies with light rains, while the rest of Northern and Central Luzon will experience isolated light rains. Metro Manila and the rest of the country can look forward to generally fair weather with a chance of isolated rain showers or thunderstorms.
For sea travelers, gale warning is up over the seaboards of Northern and Southern Luzon, and the eastern seaboards of Central Luzon. These areas will experience rough to very rough sea conditions due to the surge of amihan. Coastal waters in the rest of the country will be moderate to rough.
Amihan peaks in January
Amihan, characterized as cold and dry air blowing from mainland China or Siberia, began to affect the Philippines last October 16, 2014. However, during the ber months, it’s still not completely felt all over the country. According to PAGASA Weather Forecaster Jori Loiz, this wind system will peak on January wherein the ocean has lower thermal capacity, which means it cannot absorb much heat. Minimum temperatures are usually recorded during this month.
