SINGAPORE — Air quality over the next 24 hours is expected to be in the moderate range, said the National Environment Agency (NEA) in a haze update at about 5.45pm on Tuesday (Aug 30).

The 24-hour Pollutant Standards Index (PSI) reading is between 51 and 100 in the moderate range. The one-hour PM2.5 concentration over the next 24 hours is also expected to remain in Band I (Normal), which is between 0µg/m3 to 55µg/m3.

On Wednesday, prevailing winds are forecast to blow from the south-east or south and thundery showers expected in the late morning and afternoon.

On Tuesday, air quality remained in the good to moderate range. There were thundery showers over many parts of Singapore in the late morning and afternoon.

“Four hotspots were detected in Sumatra, and there was no visible haze there,” said the NEA.

Given the air quality forecast for the next 24 hours, the NEA said “everyone can continue with normal activities. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention”.
