Since this morning, conditions have been visibly hazy and a strong burning smell detected across many parts of Singapore.
Drier weather conditions in the region have led to an escalation in hotspot activities mainly over central Sumatra. 101 and 138 hotspots were detected over Sumatra on 15 and 16 June 2013 respectively.
The smoke haze from the fires in Sumatra was brought over by prevailing winds blowing from the southwest or west, and has affected Singapore since 13 June 2013. The hazy conditions are expected to persist for the next few days.
