Southwest Monsoon Triggers Intense Rainfall in Western Philippines, Warning Issued for Floods and Landslides

The southwest monsoon will bring intense rainfall over Zambales and Bataan, while heavy downpours are expected in six areas, posing a risk of numerous flooding events and landslides, especially in high-risk areas, according to the state weather bureau on Tuesday. These rainfall conditions are likely in the next 24 hours despite the absence of any tropical cyclone within the Philippine Area of Responsibility (PAR), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its 5:00 a.m. press briefing. The intense rainfall projected in Zambales and Bataan could bring 100 to 200 millimetres during this period. PAGASA warned of possible numerous flooding events, especially in urbanized, low-lying and near-river areas. Landslides are also likely in moderate to high-risk areas. Meanwhile, heavy downpours, translating to rainfall of 100 mm, are likely in Pangasinan, Tarlac, Pampanga, Cavite, Batangas and Occidental Mindoro in the next 24 hours. Under this rainfall intensity, localized flooding and landslides are likely, especially in the same high-risk areas. PAGASA has issued a heavy rainfall outlook until Thursday, with more areas likely said to be affected. — Edg Adrian A. Eva
