Singapore may experience slight haze in the mornings: NEA

SINGAPORE - Some people in Singapore may have experienced hazy conditions recently. This can be attributed to the accumulation of particulate matter under stable atmospheric conditions, the National Environment Agency (NEA) said in a statement yesterday night.

Although the 3-hour PSI in northern Singapore was slightly elevated yesterday morning, the 24-hour PSI remained in the "Good" band throughout the day. At 10pm yesterday night, the 24-hour PSI was between 29 to 39.

As of 10am today, the 24-hour PSI stood at 27 to 43. The 10am 3-hour PSI was 35 and PM2.5 concentration between 16 to 24 micrograms per cubic metre.

"The number of hotspots detected in Sumatra these last few days has been low due to cloudy conditions and partial satellite coverage," NEA said, adding that only seven hotspots were detected yesterday, mainly in northern Sumatra. However, NEA noted that smoke haze was visible over Riau province in central Sumatra.

"For the next few days, the prevailing northeasterly winds will keep the haze from Sumatra as well as volcanic ash from the Mount Sinabung and Mount Kelud eruptions away from Singapore.

"The likelihood of transboundary haze or volcanic ash affecting Singapore thus remains low. However, we may experience occasional slight haze due to the accumulation of particulate matter under stable atmospheric conditions, particularly in the morning.

"Localised showers are expected in the late afternoon in the next few days," NEA said.

NEA said it will continue to monitor the situation and provide updates as necessary.
