Slightly hazy conditions recorded over Singapore as PSI rises
The Pollutant Standards Index (PSI) on Monday afternoon climbed to a three-hour average of 47 at 2pm as people around Singapore complained of hazy conditions and a burning smell in the air.
The three-hour average PSI at 1pm was 43, while that at noon was 39, indicating it was on the rise although still in the "good" range. The PSI is a measure of air quality.
The National Environment Agency's advisory for Monday said that Singapore may experience slightly hazy conditions in the morning due to the accumulation of particulate matter under light wind conditions.
Minister for Environment and Water Resources, Vivian Balakrishnan, said on his Faceboko page that the visible haze is due to south-west winds blowing from hotspots in Riau and local accumulation over Singapore. "Fortunately, the situation should improve as rain is forecasted over the next few days to douse the fires in Riau. The southerly wind will also be strengthening," he added.
