Why many places in Philippines experience flashfloods?

Many places in the Philippines experience flash floods due to a combination of heavy rainfall, tropical storms, and the country's topography. The archipelago's mountainous terrain causes water to flow rapidly into low-lying areas, overwhelming drainage systems. Deforestation and urbanization further exacerbate the situation by reducing natural water absorption and increasing runoff. Additionally, the Philippines' location in the Pacific typhoon belt makes it particularly vulnerable to intense weather events.
