Singapore, 27 August 2015 –  There was an improvement in the haze situation in Singapore today due to a slight shift in the direction of the prevailing winds. As at 7pm, the 24-hr PSI was 60-70, in the Moderate range.

2          13 hotspots were detected in Sumatra today. The low hotspot count was due to cloud cover. Smoke haze was observed in southern parts of Sumatra.

3           For  tomorrow the prevailing winds are forecast to continue blowing from the southeast. Occasional slightly hazy conditions may be expected in the afternoon if the winds blow from the south. Showers are forecast for Singapore in the afternoon. The 24-hr PSI for the next 24 hours is expected to be in the Moderate range.

4          The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity. Reducing outdoor activities and physical exertion can help limit the ill effects from haze exposure. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention. Given the air quality forecast for the next 24 hours, everyone can continue with normal activities.
