Be prepared for the rainy season.

According to National Environment Agency's (NEA), the north-east monsoon is expected to set in around mid-November.

Periods of moderate to heavy rain are expected to last till January.

During this time, high tides ranging from 3.0 to 3.2 metres could lead to localised flash floods in low-lying areas such as Lorong Buangkok, Jalan Seaview, Meyer Road, Lorong 101 to Lorong 106 Changi and Everitt North Road.

Motorists travelling along roads in these areas are advised to exercise caution if there are flash floods.
