Most are in Riau province. The other hotspots on the island are primarily further north, in Aceh and North Sumatra.
SINGAPORE – The number of hotspots in Sumatra as tracked by satellites has gone up sharply in the last two days to reach 159 yesterday, the National Environmental Agency (NEA) said.
Of these hotspots, 63 are detected in the Riau province in central Sumatra, which is about 280km from Singapore. Some localised smoke plumes are observed to emanate from the hotspots. The other hotspots on the island are primarily further north, in Aceh and North Sumatra.
Although the smoke haze is not being blown towards Singapore at this time due to wind direction, the air quality here might take a hit if winds start to blow from the west.
At the moment, the winds are blowing from the southeast or the east.
NEA said that some states in Peninsular Malaysia have been experiencing a deterioration in their air quality since late morning yesterday with the highest Air Pollutant Index (PSI) reading at 5am today being 98 in Bukit Rambai, Malacca.
Over the next two days, dry weather conditions are expected to persist in most parts of Sumatra.
NEA will provide further haze alerts to the public if these events become more likely.
