SINGAPORE — No major hotspots have been detected in the region and the current likelihood of a return of transboundary haze "is low", the National Environment Agency (NEA) said as the skies over Singapore turned hazy for a brief spell on Friday (April 21).

The hazy conditions, particularly over southern and eastern Singapore early on Friday morning, was due to "accumulation of particulate matter under light wind conditions", NEA added. The skies cleared up after heavy and widespread rain fell over Singapore in the morning. 

"Based on the latest satellite images, there were no significant hotspots or smoke haze detected in the nearby region," said NEA in a statement. "The likelihood of transboundary haze affecting Singapore is low."

Some residents woke up to the unwelcome sight of hazy skies on Friday morning, as the 24-hour Pollutant Standards Index (PSI) readings edged towards to the unhealthy range.

The overall 24-hour PSI readings for Singapore at 7am was between 62 and 93. The southern and eastern parts of Singapore registered the highest readings, at 93 and and 87 respectively.

The readings have since fallen. At 3pm, the overall 24-hour PSI readings for Singapore were between 59 to 87, which is in the moderate range.

The air quality is considered to be in the unhealthy range when the 24-hour PSI readings are above 101, according to the NEA.
