SOUTHWEST MONSOON (HABAGAT) will continue to be enhanced by the newly-formed TROPICAL DEPRESSION NIMFA and WEAK LPA 99W. It will continue to bring mostly cloudy to cloudy skies with scattered to occasional light to moderate to at times rain showers and thunderstorms across MIMAROPA, BICOL REGION, NORTHERN AND WESTERN VISAYAS, KALAYAAN ISLAND GROUP, AND SULU ARCHIPELAGO. Winds of 30-50 kph will be expected along this monsoon with 2 to 4 meters of waves, making the seas rough and dangerous to small and medium-sized sea vessels.
NORTHEASTERLIES will bring cooler breeze with isolated to scattered rain showers and possible thunderstorms across EXTREME NORTHERN LUZON.
Meanwhile, TROUGH of TROPICAL DEPRESSION NIMFA + WEAK LPA 99W will bring mostly cloudy to cloudy skies with isolated to scattered rain showers and thunderstorms across NORTHERN AND CENTRAL LUZON including METRO MANILA AND CALABARZON. At 12:00 PM today, TD NIMFA has remained almost stationary over the North Philippine Sea and was located about 731 km E of Basco, Batanes (21.7N 128.9E), with maximum sustained winds of 55 kph near the center. On the other hand, WEAK LPA 99W remains overland, currently in the vicinity of Talugtug, Nueva Ecija (15.7N 120.8E). This LPA is expected to dissipate and be absorbed into the western trough of TD Nimfa today.
