SINGAPORE - Air quality is likely to remain in the moderate range on Saturday (Sept 3), said the National Environment Agency (NEA).
The Pollutant Standards Index (PSI) for the next 24 hours is forecast to be moderate, NEA said in an advisory at 6pm on Friday.
The one-hour PM2.5 concentration is expected to be normal (Band I).
Given the air quality forecast, everyone can continue with normal activities.
People who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
As at 5pm on Friday, the 24-hour PSI was 45-57, in the good to moderate range.
A total of 13 hot spots were detected in Sumatra, mostly in southern Sumatra, and there was no visible haze observed there, NEA said.
Thundery showers are also expected in the late morning and early afternoon of Saturday in Singapore.
There is a possibility that Singapore could experience slightly hazy conditions this weekend.
"Over the weekend, the prevailing light winds may shift to blow from the south-west or west, and persist into next week. Dry weather conditions are expected for southern Sumatra," NEA said.
