The La Mesa Dam continues to overflow as of Monday morning due to the ongoing heavy rains brought by the southwest monsoon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported.

The water level at the dam has reached 80.17 meters, exceeding its spilling level of 80.15 meters. This is expected to affect low-lying areas and barangays along the Tullahan River in Quezon City, Valenzuela, Caloocan, Malabon, and Navotas.

Residents in these and nearby areas, especially those living near riverbanks, are advised to take precautionary measures.
