The water level at La Mesa Dam in Quezon City breached the critical level on Sunday amid heavy rains caused by the Southwest Monsoon (Habagat).

The dam's critical level is 79.50 meters while its spilling level is at 80.15 meters.

Should water be released or spill from the dam, low-lying areas and barangays along the Tullahan River, from Quezon City, Valenzuela City, Caloocan City, Malabon City, and Navotas may be affected.
