PSI remains in moderate range on Tuesday evening

SINGAPORE - The Pollutant Standards Index (PSI) reading at 7pm this evening remains in the moderate to unhealthy range of 88-104, the National Environment Agency (NEA) said in a haze update on its website.

NEA said that a change in the prevailing wind direction, which is blowing from the southeast, attributed to the improvement in the hazy conditions which affected Singapore yesterday.

The total number of hotspots detected in Sumatra and Kalimantan today was 121 and 72 respectively, with smoke haze visible in some parts of Sumatra and Kalimantan. The haze from central Sumatra is blown by the prevailing winds across the Strait of Malacca towards western parts of Peninsular Malaysia.

NEA added that Singapore can expect showers in the late morning and early afternoon tomorrow, and that prevailing winds are forecast to blow from the southeast or south.

The overall air quality for the next 24 hours is also expected to remain in the moderate to unhealthy range, depending on wind conditions.

NEA advises the public, especially the elderly, pregnant women, children, and those with chronic heart and lung conditions, to avoid prolonged or strenuous outdoor physical activities.
