Complete Guide
Heavy rain and flash floods in Singapore
Short intense rainfall can overwhelm drainage in certain places. Good planning focuses on verified flood alerts, safer travel routes and household-specific risks rather than copying an emergency plan from another country.
Use PUB alerts and myENV
PUB provides flood-related advice and alerts, and myENV includes weather, water level and flash-flood notifications. Review alerts ahead of commuting and reroute when authorities report dangerous water levels.
Home preparations that actually matter
Maintain drainage where responsible, identify higher storage for important items and understand your buildingโs flood barriers or safe movement procedures. Keep electricity-related safety central to any plan.
Travel when the weather deteriorates
Do not enter floodwater on foot or drive through a flooded road simply because another person passed. Visibility, current and hidden hazards can change quickly, and safer alternative routes are preferable.
Communicate and leave safely
Agree contact plans for family members, especially children or people needing assistance. Follow authorities when evacuating and move to safer higher ground only when the route itself is safe.
Recovery and insurance records
Wait until the site is safe before documenting losses or cleaning. Keep a private inventory for insurers and replace used readiness supplies; do not reconnect damaged electrical equipment without professional advice.
Frequently asked questions
Can I cross shallow floodwater to reach home?
Avoid walking into floodwater. It can hide open drains or sudden currents. Follow PUB and emergency responder advice.
What alerts should I enable?
PUB flood information and myENV heavy-rain, high-water-level and flash-flood alerts are useful starting points.
Should I touch an electrical switch during flooding?
No. Do not operate electrical switches or appliances if you are wet or standing in water. Follow professional and official safety instructions.
