QUEZON CITY — La Mesa Dam continues to operate at Alert Level 3 as southwestern monsoon rains deliver sustained precipitation across the metro, according to Quezon City government officials. The dam's water level has experienced a modest increase over the past 24 hours, reflecting the impact of the ongoing habagat system affecting the region.

The Alert Level 3 classification indicates elevated water conditions requiring heightened monitoring and readiness protocols. Local government units in Quezon City have maintained close surveillance of the dam's status to ensure public safety in downstream communities that depend on the facility for water supply and flood management.

The southwest monsoon, which typically brings heavier rainfall to western portions of the Philippines during this season, has prompted water resource authorities throughout the National Capital Region to increase their monitoring operations. Residents in low-lying and flood-prone areas near the dam have been advised to remain vigilant and prepare for potential flooding.

Official updates on the dam's status are expected to continue as weather conditions persist. Authorities remind the public to heed warnings from local officials and to avoid crossing swollen waterways or venturing into hazardous areas during this period of elevated water levels.
