Public Advisory

PUB advises pedestrians, motorists and residents to exercise caution during the monsoon season when flash floods may suddenly and quickly occur in the event of heavy storms.

If you are outside during a flood:


  • Be alert and move immediately to higher ground. Do not wait for instructions to move. Stay put until the flood subsides.
  • Be aware of drains especially open drains and areas known to flood suddenly.
  • Do not walk through moving water. 15cm of moving water can make you fall. If you have to walk in water, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.


  • Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely. 30cm of water can stall your car. 60cm of water can carry away most vehicles including SUVs.

If you are at home or in your shop/office:

Residents / Business Owners

  • Do not touch electrical equipment if you are wet or standing in water.
  • If you live in low-rise housing, secure your home/shop/office. Move essential items to an upper floor.

Protect your belongings

Monsoon Preparation

The Northeast Monsoon is likely to set in around December 2015 and last until February 2016. Ahead of the monsoon season, PUB has distributed flood advisories to some 500 residential units and shop-houses in low-lying areas. Some of these areas are subject to tidal influence and could experience localised flash floods should heavy rain coincide with high tides. The advisory provides tide information and precautionary tips that can be taken to protect their belongings. Click here to download a copy of the advisory.
