Singapore, 16 September 2014 – Showers affected the northern parts of Singapore in the late afternoon today.  As at 7pm today, the 24-hr PSI is 63-71, in the Moderate range. The lower PSI readings compared to yesterday are due to a change in the wind direction, with prevailing winds over Singapore blowing from the southeast.

2          The total number of hotspots detected in Sumatra today was seven. The low hotspot count was due to partial satellite coverage and cloud cover. Widespread smoke haze was observed over southern and central Sumatra.

3          For tomorrow, the prevailing winds are forecast to blow from the southeast. Showers in the afternoon are expected for Singapore. The overall air quality 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.
