Singapore, 18 December 2013 – Singapore has been experiencing Northeast Monsoon conditions since the onset of the Northeast Monsoon season in the region in late-November 2013. In the past weeks, short-duration thundery showers affected Singapore mostly in the afternoon and early evening. As of 17 December, the wettest areas were in the northeast with rainfall of around 85 to 98% of the long-term monthly average. The driest parts of the island were in the south and west where 30 to 40% of the long-term monthly average rainfall was recorded. Overall rainfall for December 2013 is expected to be around 10 – 30% above average.

2According to the Meteorological Service Singapore (MSS), a steady strengthening of winds over the South China Sea known as a monsoon surge, is expected to affect the region over the next few days. The surge is likely to bring intermittent rain, heavy at times, with occasional windy conditions to Singapore on one to two days between 19 and 22 December 2013. High tides of 3.1m are expected during this period.

3Heavy rain coinciding with high tides could lead to localised flash floods especially in the low-lying areas. The public are advised to exercise caution during the monsoon season when flash floods may occur in the event of heavy rainfall.
