Heavy Rain Warning
Subscribers will receive an SMS alert from the Meteorological Service Singapore (National Environment Agency) whenever heavy rain is expected to affect Singapore. The SMS alert will contain information which includes where heavy rain will be expected, and tidal change data should high tide coincide with heavy rainfall. Another SMS will be sent to subscribers if heavy rain is no longer expected or has ceased. Click here to view the Tide Times.
The Heavy Rain Warning information is also available on the NEA website.
To unsubscribe, you have to reply “U” to the SMS alert that you received.
High Water Level Alert
As part of its comprehensive drainage management and control, PUB has installed 208 sensors in key canals and drains to track the water levels.
Subscribers will receive progressive SMS alerts if the water level in the selected canal rises above 50%, 75%, 90% and 100% of the canal's depth. Separate SMS alerts will be sent to subscribers to inform them when the water level recedes gradually to below 50%.
