Air quality in parts of Singapore in unhealthy range

In its Tuesday evening advisory, the National Environment Agency (NEA) said that scattered hotspots were detected in Kalimantan and Sumatra, while a few hotspots were detected elsewhere in southern Southeast Asia.

Moderate to dense smoke plumes from southern Sumatra and West Kalimantan were observed drifting towards Singapore, NEA said.

With dry weather forecast to persist over Kalimantan and southern and central Sumatra, as well as prevailing east-southeasterly to southeasterly winds, smoke haze is likely to continue drifting to Singapore.

The 24-hour PSI in Singapore is forecast to be in the high moderate to mid unhealthy range, NEA said.

When planning outdoor activities for the next 24 hours, the public is advised to use the 24-hour PSI forecast and health advisories.

When 1-hour PM2.5 levels are elevated, healthy people are advised to reduce strenuous outdoor activity for the next hour, while the elderly, pregnant women, children and people with chronic heart or lung conditions should avoid such activity.
