What Are Flash Floods in Bali?
Flash floods are sudden, rapid floods caused by heavy rainfall, often in mountainous or coastal areas. In Bali, intense storms can overwhelm rivers and drainage systems within minutes, turning roads and villages into fast-moving water channels.
Common Causes and Risk Areas
Monsoon rains, deforestation, and clogged drainage increase flash flood risk. Low-lying river valleys, southern coastal areas, and steep rice terraces are especially vulnerable. Heavy rain combined with volcanic soil runoff can trigger dangerous surges in minutes.
Safety Tips and Preparedness
Monitor local weather alerts and avoid travel during extreme downpours. Do not attempt to cross flooded roads or bridges. Move to higher ground immediately if water rises quickly. For official updates and evacuation routes, visit BNPB.
