Singapore is set to experience another spell of prolonged rainfall from January 17 to January 19, 2024, as a new monsoon surge sweeps through the region. This weather event, marked by heavy downpours, high tides, and cooler temperatures, poses challenges such as flash floods in coastal areas. In this article, we delve into the details of the upcoming monsoon surge, its potential impacts, and how to stay prepared during this wet season.
Understanding the Monsoon Surge
A monsoon surge occurs when strong winds over the South China Sea form extensive rain clouds, bringing heavy rainfall, strong winds, and cooler weather. This phenomenon is common during Singapore’s wet northeast monsoon phase, typically from December to January.
Key Highlights of the Upcoming Surge:
- Rainfall: Prolonged, islandwide downpours are forecasted from January 17 to 19.
- High Tides: Tides are expected to peak at 3.2m on January 17 and 3.1m on January 18, increasing the risk of coastal flooding.
- Temperatures: Cooler conditions with daily lows of 22°C and highs of 34°C are expected.
Impacts of Prolonged Rainfall and High Tides
The combination of heavy rainfall and high tides could lead to flash floods, particularly in low-lying coastal areas. Recent monsoon surges have caused similar disruptions, including:
- Flooding: Flash floods in areas like Jalan Seaview during previous high tides.
- Transportation Delays: Flight diversions and delays due to adverse weather.
- Damage to Infrastructure: Fallen trees, potholes, and overwhelmed drainage systems.
Staying Prepared During the Monsoon Season
The national water agency PUB and the Meteorological Service Singapore (MSS) have issued safety recommendations for residents and businesses:
- Monitor Weather Updates: Use the myENV app or subscribe to PUB Flood Alerts on Telegram for real-time updates.
- Flood Defenses: Install protection devices like flood barriers in flood-prone areas.
- Emergency Plans: Keep emergency kits ready and plan alternative routes for commuting.
PUB’s Quick Response Teams are on standby to assist in managing any flooding incidents and supporting affected communities.
Long-Term Climate Considerations
The intensity and frequency of monsoon surges are expected to increase due to climate change. Rising sea levels and more frequent extreme weather events could exacerbate flooding risks in Singapore.
Key Findings from Climate Studies:
- Sea-Level Rise: Projections show sea levels could rise by up to 1.15m by 2100 in the worst-case scenario.
- Increased Rainfall: The northeast monsoon season could become wetter by up to 58%.
To combat these challenges, Singapore is investing in advanced flood models to simulate and prepare for inland and coastal flooding scenarios.
Conclusion
As the monsoon surge approaches, it’s crucial for residents and businesses in Singapore to stay vigilant and prepared. By taking proactive measures and staying informed, we can mitigate the impacts of prolonged rainfall and high tides during this wet season.
