AsiaOne 16 Oct 16;

SINGAPORE - Singapore may experience slightly hazy conditions on Saturday (Oct 15) night and on Sunday, the National Environment Agency (NEA) said.

"Smoke plumes and slight haze from hotspots in central Sumatra were observed to be blown by the prevailing west-southwest winds towards the Strait of Malacca," NEA said in an advisory issued on Saturday evening.

A total of 20 hotspots were detected in Sumatra, the agency said.

On Sunday, the air quality is expected to worsen, but it is not likely to reach unhealthy levels.

The Pollution Standards Index (PSI) is forecast to be in the high end of the moderate range.

The one-hour PM2.5 concentration is expected to fluctuate between 'Normal' and the low end of 'Elevated'.

Thundery showers are forecast for Singapore in the early morning of Sunday.

Given the air quality forecast for the next 24 hours, everyone can continue with normal activities, NEA said.
