HAZE SITUATION UPDATE (21 OCTOBER)

 

Singapore, 21 October 2014 –There were thundery showers in Singapore in the late morning and afternoon today. At 7pm, the 24-hr PSI was 68-80, in the Moderate range.

 

2           The total number of hotspots detected in Sumatra and Kalimantan today was two and 58 respectively. The low hotspot counts are due to cloud cover over both Sumatra and Kalimantan. Smoke haze was visible in southern Kalimantan.

 

3            For tomorrow, the prevailing winds are forecast to be light and variable in direction. Thundery showers are expected for Singapore in the late morning and early afternoon. There may be occasional slight haze. The 24-hr PSI for Singapore is expected to be in the high-end of the Moderate range but may enter the low-end of the Unhealthy 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. Given the air quality forecast for the next 24 hours, healthy persons should reduce prolonged or strenuous outdoor physical exertion. The elderly, pregnant women and children should minimise prolonged or strenuous outdoor physical exertion, while those with chronic lung or heart disease should avoid prolonged or strenuous outdoor physical exertion. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
