Singapore, 28 August 2015 –  The weather was fair in Singapore today. As at 7pm today, the 24-hr PSI is 64-70, in the Moderate range.

2          Two hotspots were detected in Sumatra today. The low hotspot count was due to partial satellite pass. Smoke plumes and haze were visible in in the southern half of Sumatra.

3           For  tomorrow the prevailing winds are forecast to blow from the southeast. There may be occasional slight haze from Sumatra in the afternoon if the winds shift briefly to blow from the south. Thundery showers are forecast for Singapore in the late morning and early 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.
