MANILA – Luzon residents face mounting flood risks Wednesday as the southwest monsoon, locally known as the habagat, maintains its assault on the region with sustained heavy rains. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) had issued a tiered alert system by late morning, with multiple municipalities placed under color-coded rainfall warnings reflecting escalating danger levels. Areas designated under red warnings face the most severe flooding threat, while those under orange and yellow warnings remain vulnerable to significant water accumulation and runoff. The southwest monsoon has persisted across the archipelago, channeling moisture-laden winds that have saturated atmospheric conditions over Luzon. Residents in affected zones have been urged to remain vigilant and prepared for potential evacuation, with local disaster management units coordinating response operations ahead of any major inundation events. Weather officials advised the public to monitor updates regularly and heed all warnings issued by PAGASA and local authorities.
