The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued flood bulletins on Thursday, July 3, for the Pasig-Marikina-Laguna de Bay and Tullahan River basins due to light to moderate rains brought by the southwest monsoon or “habagat.”
The bulletins, in effect from 6 a.m. to 6 p.m., warn of potential increases in water levels across several rivers and tributaries that could lead to flooding in adjacent communities.
Areas at risk are:
* Upper Marikina River: Rodriguez, Antipolo, and San Mateo (Rizal); Quezon City; and Marikina City
* Lower Marikina River: Pasig City, Mandaluyong City
* Pasig River: Pasig City, Makati City, Mandaluyong City, Manila City
* San Juan River: Quezon City, San Juan City, Manila City
* Mango River: Rodriguez, Rizal
* Nangka River: Marikina City; San Mateo and Antipolo (Rizal)
* Cainta River: Cainta, Rizal
* Taytay River: Taytay, Rizal
* Buli Creek: Pasig City, Cainta
* Tullahan Rover: Quezon City, Caloocan City, Malabon City, Navotas City, Valenzuela City
PAGASA said light to moderate rains are expected to continue in these areas over the next 12 hours.
Residents living near riverbanks, mountain slopes, and low-lying areas are urged to remain vigilant for possible flash floods.
Local disaster risk reduction and management councils have also been advised to stay on alert.
“Road and street flooding is possible in several areas due to impounding water, poor or clogged drainage systems, and higher tide levels, which could render some roads not passable,” PAGASA added.
