TACLOBAN CITY – The tail-end of the frontal system may trigger flooding in major rivers in the Eastern Visayas region, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has warned.
Several areas in the region have been experiencing rain showers since Tuesday morning.
In an advisory, PAGASA identified several rivers in six provinces that would likely be affected by the downpour -- Sangputan, Palo, Solano, Daguitan, Marabong, Cadacan, Bongquirogon, Salug, Pagbanagaran, Pagsangahan, and Binahaan in Leyte; and Catarman, Bugko, Pambujan, Catubig, Palapag, Mano, and Gamay in Northern Samar.
Other rivers include Oras, Dolores, Ulot, Taft, Borongan, Suribao, Llorente, Balangiga, and Sulat in Eastern Samar; Basey, Silaga, Calbiga, and Jibatan in Samar; Bisay, Himbangan, and Pandan in Southern Leyte; and all river systems in Biliran.
People living in low-lying areas near these river systems have been advised to stay alert for possible flash floods.
Those residing near mountain slopes have been told to watch out for signs of landslides.
PAGASA said the weather system affects the Visayas and the northern section of Mindanao and may cause scattered light to occasionally moderate rains and thunderstorms.
The tail-end of the frontal system, also called “shear line,” is the convergence of northeasterly and easterly winds that forms rain clouds.
Another weather advisory is expected to be issued on Wednesday.
