Manila: The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Saturday warned low-lying areas in Metro Manila as the water level of the La Mesa Dam in Quezon City has breached overflow elevation.

According to Philippines News Agency, as of 2 p.m., the dam's water level has reached 80.22 meters, exceeding its 80.15-meter overflow elevation, PAGASA said. 'Excess floodwaters from La Mesa Dam will flow directly into the Tullahan River,' it stated.

PAGASA identified the affected areas as including Caloocan, Malabon, and Navotas cities; Fairview, Forest Hills Subdivision, Quirino Highway, Sta. Quiteria, and San Bartolome in Quezon City; as well as North Expressway and La Huerta Subdivision in Valenzuela City. Residents in these areas, particularly those living near riverbanks, have been advised to take appropriate actions to ensure their safety.

PAGASA also warned that continuous rainfall over the dam's watershed could further raise the river level. 'It should also be noted that aside from the outflow from the reservoir, continuous rainfall over the watershed may further increase the river water level,' it said.

PAGASA emphasized its commitment to continue monitoring the hydrological condition of La Mesa Dam and providing updates to concerned agencies and local government units to ensure prompt response and safety of the communities.
