The surge of NORTHEAST MONSOON (AMIHAN) will continue to bring cooler conditions, mostly cloudy to cloudy skies with occasionally light to at times moderate rain showers or possible thunderstorms EXTREME NORTHERN-NORTHERN-EASTERN LUZON, becoming more frequent along BICOL REGION AND THE VISAYAS. Fresh to strong breeze (30-50 kph) will blow, making the seas moderate to rough (2 to 4 meters) and risky to small and medium-sized sea vessels.
