Update on Hotspot and Haze Situation
2 Moderate to dense smoke plumes continued to be observed in southern Sumatra and Kalimantan. Smoke haze from southern Kalimantan was observed drifting towards the vicinity of Singapore.
3 Dry conditions are expected to persist over the southern parts of Sumatra and Kalimantan. Although showers are forecast over Singapore and the surrounding region tomorrow, the prevailing southeasterly or southerly winds could transport smoke haze towards Singapore. The 24-hr PSI for Singapore is forecast to be in the Moderate to Low Unhealthy 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.
