A MONSOON TROUGH will bring mostly cloudy to cloudy (overcast) skies with isolated to scattered rain showers and thunderstorms across BICOL REGION AND EASTERN VISAYAS. Meanwhile, TROPICAL DISTURBANCE (LPA) 97W had entered the Philippine Area of Responsibility (PAR) and is currently embedded within the active Monsoon Trough and is likely to develop into a weak Tropical Cyclone within the next 24 to 48 hours. As of 2:00 PM today, the center of LPA 97W was located over the eastern portion of the Philippine Sea or about 1,028 km East of Virac, Catanduanes (13.6°N Lat 133.7°E Lon). It is currently quasi-stationary, with maximum sustained winds of 35 kph. The potential of becoming a significant Tropical Cyclone within the next 24 hours is now MEDIUM (35-65% chance).
SOUTHWESTERLIES (Southwesterly Surface Windflow/Weak Habagat) will bring partly cloudy to cloudy skies with breezy conditions and isolated to scattered rain showers or thunderstorms across THE WESTERN SECTION OF NORTHERN LUZON including BATANES AND BABUYAN ISLAND GROUP, MIMAROPA, KALAYAAN ISLAND GROUP, SULU ARCHIPELAGO, WESTERN VISAYAS, AND ZAMBOANGA PENINSULA.
THE REST OF THE COUNTRY will be partly cloudy to cloudy skies with chances of isolated to scattered rain showers and thunderstorms in some areas especially in the afternoon or evening.
**Residents are advised to be on alert for possible flashfloods, landslides or lightning strikes during the occurrence of Severe Thunderstorms.
Important note: In the infrared (IR) satellite image shown above: BLUE areas indicate Clear Skies with a Few Clouds; GREEN = Partly to Mostly Cloudy Skies; YELLOW = Mostly Cloudy to Hazy Skies with Possible Slight-to-Moderate Rainfall; and RED = Thunderstorms with Moderate to Heavy to sometimes Extreme Rainfall.
