Rainy weather is likely to be experienced and elevate the risk for flooding and landslides in Region V (Bicol) and the Visayas this weekend.

“Communities in those areas must be alert to such dangers,” Philippine Atmospheric, Geophysical and Astronomical Services Administration hydrologist Aileen Abelardo said.

Heavy or prolonged rainfall can set off flash floods and landslides, particularly in areas that are either susceptible to these hazards or already saturated due to previous rain there, she noted.

Surface runoff and swelling of river channels can cause flooding in areas that have not experienced such rainfall, Pagasa also said.

In Western Visayas, Pagasa said waterways of particular concern are Malogo, Sicaba, Grande, Himogaan, Danao, Upper Tabanan, Sipalay, and Lower Ilog in Negros Occidental; Panay, Mambusao, Panay Malinao, Alingon and Balantian in Capiz;

Sibalom, Ipayo, Cagaranan, Palawan, Cairauan, Dalanas and Tibiao in Antique, Pinantan, Barotac, Akalaygan, Jalaud, Jalano, Jagdong, Jalaur, Lamunan, Jaro-Aganan, Sibalom, and Guimbal in Iloilo province, Ibajay, Aklan and Jalo in Aklan, and all waterways in Guimaras.

Pagasa weather forecaster Ana Clauren said the intertropical convergence zone (ITCZ) that brought rain to Bicol and the Visayas this week already moved away from these areas.

However, rain is still possible in those areas this weekend due to the tail-end of a frontal system (TEFS), she noted.

“Light to moderate with at times heavy rainfall may occur there then,” she said.

She, however, clarified that “such LPA is less likely to become a tropical cyclone”. In Bacolod City, the Disaster Risk Reduction and Management Office reported flooding in at least three puroks in barangays Mandalagan and Bata, and several streets because of clogged waterways and overflow of flood waters from the creek, due to intermittent heavy rainfall, as of 2 p.m. yesterday.*PNA
