Haze Situation Update (October 12)

Singapore, October 12, 2014 - The hazy conditions that persisted overnight gradually improved this morning due to a change in the prevailing wind direction. There were showers over parts of Singapore in the late afternoon.

At 7pm, the 1-hr concentrations of PM2.5 were 28 - 42 ug/m3, and the 24-hr PSI was 86 - 99, in the Moderate range.

The total number of hotspots detected in Sumatra and Kalimantan today was 41 and 312 respectively.

The low hotspot count in Sumatra was due to partial satellite coverage and cloud cover over parts of the island. Widespread smoke haze is visible in central and southern Sumatra.

Smoke haze from central Sumatra is blown by the prevailing winds across the Strait of Malacca towards the western part of Peninsular Malaysia. Widespread smoke haze is also visible in southern Kalimantan.

For tonight and tomorrow, the prevailing winds are forecast to be light and variable in direction. As there is smoke haze from the region still around us, we can expect hazy conditions from time to time.

Thundery showers are also expected tomorrow in the afternoon. The overall 24-hr PSI for Singapore is expected to be in the high-end of the Moderate range and the low-end of the Unhealthy range.

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.
