The easterlies will become a dominant weather system in several areas, while weather in extreme northern Luzon and southern Mindanao will be affected by the northeast monsoon and the intertropical convergence zone (ITCZ). Batanes may also experience cloudy and rainy weather because of the northeast monsoon.
