SINGAPORE – The air quality on Friday is expected to be in the moderate range, the National Environment Agency (NEA) has said in its haze update on Thursday (Oct 29) evening.

Thundery showers are forecast between midnight and pre-dawn hours, NEA said.

The 24-hour Pollutant Standards Index (PSI) remained in the moderate (51-100) range on Thursday. At 5pm, the 24-hour PSI was 56 to 67, in the moderate range. The three-hour PSI, which is not tied to health advisories, was 58.
 
There has been a significant reduction in the extent of the haze in Sumatra and Kalimantan due to showers in the region, NEA said. However, haze was still observed in parts of  Sumatra.

On Friday, the prevailing winds are expected to be weak and to blow from the northeast or east. Haze usually drifts to Singapore when the winds blow from the south.
 
NEA advised that 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.
