MANILA — The relentless rains from the trough of Typhoon Yagi (formerly severe tropical storm Enteng) and the southwest monsoon, locally known as “habagat,” continue to drench parts of Luzon, leading to the overflow of La Mesa Dam, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Thursday (05 SEPT 2024).

PAGASA’s 7 a.m. advisory reported that the dam’s water level had reached 80.17 meters, slightly exceeding its spilling level of 80.15 meters. While light to moderate rainfall is expected over the next 12 hours, PAGASA warned residents along the Tullahan River and low-lying areas to take precautionary measures against possible flooding.

The weather bureau also forecasted scattered rains and thunderstorms over the Cordillera Administrative Region, Ilocos Norte, and Ilocos Sur due to Typhoon Yagi’s trough. Meanwhile, the southwest monsoon will bring rains to several other regions, including Pangasinan, Zambales, Bataan, Occidental Mindoro, Metro Manila, and Central Luzon.

Scattered showers and thunderstorms are also expected in Marinduque and Romblon, while localized thunderstorms may bring isolated rain showers to the rest of the country. PAGASA further cautioned that the western section of Luzon will experience strong winds and rough seas, with moderate to strong winds expected in other parts of the island.
