Singapore not affected by transboundary haze despite surge in Sumatra hotspots: NEA
In response to queries from CNA, NEA said that this was due to favourable wind conditions.
"Based on satellite observations, smoke plumes were detected in the southern and central parts of Sumatra in recent days," the agency said.
"As the prevailing winds are mostly blowing from the southeast over Singapore and the vicinity, Singapore has not been affected by transboundary haze."
Dry conditions in the region are, however, expected to persist until the end of the week before wetter conditions return and possibly improve the regional hotspot and haze situation, NEA added.
The agency said that the ongoing dry season in the southern Association of Southeast Asian Nations (ASEAN) region is expected to last until October.
"During this period, dry conditions may occur over the region," said NEA.
"The hotspot and smoke haze situation may escalate at times, and depending on prevailing wind conditions, increase the risk of transboundary haze affecting Singapore."
If transboundary haze affects Singapore, NEA said that the government's inter-agency Haze Task Force – comprising 28 government ministries and agencies – will activate the necessary action plans to mitigate and manage the impact of the haze, should the 24-hour Pollutant Standards Index enter the unhealthy range.
"Tiered measures will be implemented depending on the intensity of the haze, along with advisories to the public," the agency added.
Sumatra reported a total of 1,292 hotspots on Monday, a jump from 94 on Jul 12.
Hotspots, which appear on satellite images, represent areas where there are high levels of heat – possibly as a result of forest or land fires.
Within the region, Riau province has been the worst hit by fires in forests and peatlands, with a total of 582 hotspots reported on Monday. This is up from 38 hotspots reported on Jul 12.
In an advisory on Jul 19 regarding transboundary haze, the Malaysian Meteorological Department, MetMalaysia, said that hotspots in Sumatra captured by satellite imagery last Friday and reported by the ASEAN Specialised Meteorological Centre could have contributed to haze carried by southwesterly winds.
It stated that the haze was affecting several states on the west coast of Peninsular Malaysia, with the agency not expecting any changes in weather or wind direction that could reduce its impact over the coming days.

SINGAPORE - Singapore has not been affected by transboundary haze despite smoke plumes being detected in Sumatra in recent days, as prevailing winds are mostly blowing from the south-east over Singapore and the vicinity, said the National Environment Agency (NEA) on July 22. The regional hot spot and haze situation should improve as wetter conditions are expected to return over the weekend, said NEA in response to queries from The Straits Times. Worsening fires in forest and peatlands in Sumatra have put Indonesia's western region on high alert. According to Indonesia's Meteorology, Climatology and Geophysics Agency, the number of hot spots – places with intense heat suggesting forest fires – in Sumatra has soared from 94 to more than 1,000 in 10 days in July. Two regencies in the West Sumatra province where more hot spots were reported - Solok and Lima Puluh Kota – declared a state of emergency on July 22. Haze pollution in the area has spread to Malaysia, which recorded unhealthy air pollution index readings in four locations on July 22. Forest fires are an annual problem in Indonesia that strains relations with neighbouring countries. Top stories Swipe. Select. Stay informed.

According to data from NEA, the 24-hour Pollutant Standards Index (PSI) readings ranged between 52 and 65 at 8pm on July 22. A PSI reading of 51 to 100 is in the moderate range. Under these circumstances, people can continue with their usual activities. Unhealthy air quality is registered when PSI levels are between 101 and 200. NEA said the dry season for the southern Asean region is expected to last till October. During this period, the region may experience dry conditions, and the hot spot and smoke haze situation may escalate at times. Depending on prevailing wind conditions, this might increase the risk of transboundary haze affecting Singapore, added NEA. NEA added that it closely monitors the regional weather and haze situation, and provides daily updates via the Metereological Service Singapore's website and the haze microsite
