Update on Hotspot and Haze Situation
2 There were showers over several areas in the region today. 15 hotspots were detected mostly over the southern and central parts of Sumatra today. Moderate smoke haze was observed from satellite imagery over southern Sumatra, blowing towards the northwest by prevailing winds
3 More showers are forecast over Singapore and the surrounding region tomorrow, with light and variable winds. The wetter conditions should keep the regional fire and haze situation subdued, with a low likelihood of transboundary haze affecting Singapore. 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.
