According to reports, a low-pressure area (LPA) spotted over Polillo Island in Quezon province on Wednesday afternoon (10 September) is expected to bring light to moderate rainfall and thunderstorms across a large portion of Luzon overnight, as per the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

• PAGASA last recorded the LPA’s location in the vicinity of Polillo Island, Quezon, at 1500 hours.
• The LPA is unlikely to develop into a tropical depression and may dissipate within the next 24 hours.
• However, it will continue to bring rain showers over Metro Manila, Cagayan Valley, Central Luzon, Calabarzon, Mimaropa, and Bicol Region until early Thursday (11 Septtember).
• After the LPA dissipates, scattered rain showers and thunderstorms may persist in these areas due to the easterlies, or warm winds from the Pacific Ocean.
• The easterlies may also bring partly cloudy to cloudy skies with isolated rain showers or thunderstorms over the rest of the country.
• As per its two-week tropical cyclone threat potential forecast, PAGASA is also monitoring two more LPAs forming east of the country. The first potential LPA may enter the Philippine Area of Responsibility (PAR) on Friday (12 September). It may move across the Philippine Sea, passing east of the Visayas and Mindanao, and approach Eastern Visayas by Sunday (14 September).
• From Sunday to Tuesday (14-16 September), it may cross portions of Southern Luzon and Visayas, and emerge over the West Philippine Sea. If it develops into a tropical depression, it will be named “Mirasol.”
