Update on Hotspot and Haze Situation
2 Moderate to dense smoke haze originating from fires in Kalimantan continued to drift towards Singapore. Smoke haze was also observed from fires detected in southern Sumatra.
3 Dry conditions are expected to persist over southern Sumatra and parts of Kalimantan. While showers are forecast over Singapore and the parts of the surrounding regions tomorrow, there remains a risk of smoke haze affecting Singapore under the easterly or southeasterly prevailing winds. The 24-hr PSI for Singapore is forecast to be in the High Moderate to Mid 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.
