Update on Hotspot and Haze Situation

2    Dry conditions continue to prevail over many parts of the surrounding region. 126 hotspots were detected mostly in the southern and central parts of Sumatra today, a slight decrease from the 174 hotspots detected yesterday. Moderate to dense smoke haze was observed over parts of southern and central Sumatra from satellite imagery, drifting in a northwesterly direction.

3    Over the weekend, dry conditions over Singapore and the surrounding region are expected to persist, and the prevailing winds are forecast to strengthen and blow mostly from the south, and southwest at times. There is a chance of slight haze affecting Singapore if the fires escalate. For the next 24 hours, the 24-hr PSI for Singapore is forecast to be in the Moderate range.

Activity Guidelines

4    The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity. For immediate outdoor activities, please check the 1-hr PM2.5 concentration readings and personal guide. Use the 24-hr PSI forecast and corresponding health advisories for planning next day outdoor activities.
