HAZE SITUATION UPDATE
(30 MARCH 2016)

Summary
The air quality for the next 24 hours is expected to be in the Moderate range. Given the air quality forecast for the next 24 hours, everyone can continue with normal activities. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention. 

Singapore, 30 March 2016 – A burning smell was detected in some parts of Singapore yesterday (29 Mar). As at 10am today the 24-hr PSI reading is 68 - 82, in the Moderate range, and the 1-hr PM2.5 is 17-32 ug/m3. For the rest of today, fair and warm conditions are forecast with prevailing winds blowing from the northeast. The air quality for the next 24 hours is expected to be in the Moderate range.

2      In recent days, the weather conditions in Singapore and the region have been generally dry with little rainfall. While hotspot activities in our surrounding nearby region have been low, there has been a rise in the number of hotspots in the northern ASEAN region which is currently experiencing its traditional dry season. This could result in an increased concentration of particulate matter such as dust particles in the atmosphere over the region. In addition, there were some local vegetation fires reported yesterday, and some wind convergence over Singapore in the late afternoon. These factors could have contributed to the burning smell and slight deterioration in our air quality in some parts of the island last night and early this morning. NEA is monitoring the situation closely and will provide further updates when necessary.

3      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, everyone can continue with normal activities. Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
