The Quezon City local government unit reported that La Mesa Dam's water level breached its overflow threshold at 1:50 p.m. on Saturday, reaching 80.15 meters amid relentless downpours affecting the Metro Manila area.

The dam's overflow comes as the National Meteorological Agency maintains red rainfall warnings for several areas in the capital region, signaling the intensity and persistence of the weather system.

La Mesa Dam serves as a critical water supply facility for Metro Manila. Its overflow status typically prompts heightened alert levels among water agencies and local government units in downstream barangays, which may experience increased water flow and potential flooding.

Officials have urged residents in low-lying areas and communities near waterways to remain vigilant and prepared for potential flash floods. The Quezon City government continues to monitor the situation as rainfall continues across the region.
