NORTHEAST MONSOON (AMIHAN) still continues to prevail bringing partly to mostly cloudy skies and cool weather conditions with occasionally light to at times moderate rain showers and possible thunderstorms across EXTREME NORTHERN LUZON, NORTHERN & EASTERN LUZON. Moderate to fresh breeze (20-45 kph) will blow, making the seas moderate to rough (1.0 to 4.0 meters) and dangerous to small or medium-sized sea vessels to navigate on.
Meantime, a SURFACE TROUGH also extends across NORTHERN tip of BICOL REGION bringing some light to moderate rain showers of thunderstorms, while over PALAWAN, WESTERN & SOUTHERN MINDANAO, the combined effect of a TROUGH of WEAK LPA and the WESTERLIES (WESTERLY WINDFLOW) will bring some passing light to at times moderate rain showers or thunderstorms..
The REST OF THE PHILIPPINES will have mostly cloudy skies with possible isolated rain showers or thunderstorms developing later.
**Residents are advised to be on alert for POSSIBLE FLASHFLOODS, LANDSLIDES OR LIGHTNING STRIKES during the occurrence of Severe Thunderstorms.
