Flash Flood Warnings Issued as Intense Showers and High Tides are Expected from 17 to 19 January

Singapore is preparing for a wet and cooler weekend from 17 to 19 January, as a second monsoon surge brings gusty winds and a drop in temperatures, according to the Meteorological Service Singapore (MSS).

The island will experience moderate to heavy thundery showers throughout the period, with temperatures potentially falling to as low as 22°C during the surge. Afterward, the temperature is expected to rise back to between 24°C and 34°C, MSS reported on 16 January.

This intense rainfall, combined with seasonal high tides, significantly raises the risk of flash floods, especially in low-lying areas such as East Coast Park. The national water agency, PUB, has warned that tides could reach up to 3.2m during the monsoon surge, resulting in elevated water levels in coastal canals.

Earlier this month, from 10 to 13 January, Singapore faced record rainfall. Pulau Tekong recorded 241.8mm of rain on 10 January, more than twice the daily average across the country’s 32 weather stations and surpassing the previous 2011 record of 238.2mm set on Pulau Ubin.

The heavy downpours caused flash floods, downed trees, potholes, and flight delays. For instance, Jalan Seaview in Mountbatten experienced flash floods when heavy rain coincided with a 2.8m high tide, overwhelming local drains and canals.

To mitigate the risk of flooding, PUB has introduced preventive measures, including the distribution of protective devices and barriers to flood-prone homes and businesses. Emergency teams have been put on standby to manage flood incidents and assist affected communities.

Residents are encouraged to stay informed through the myENV app, PUB’s Flood Alerts Telegram channel, and online flood safety resources.

As temperatures remain low, with Newton recording 21.6°C earlier this month, Singaporeans are urged to stay vigilant and prepared for further rain and strong winds, particularly in flood-prone areas.
