Update on Hotspot and Haze Situation
4 It was dry over Singapore today. As at 6pm, the 1-hr PM2.5 concentration readings were 19 – 37µg/m3, in (Band 1, Normal), and the 24-hr PSI was 62 – 76, in the Moderate range. Smoke haze was observed over Kalimantan and Sumatra.
5 For tomorrow, the winds are forecast to blow from the east-northeast. Showers are expected over Kalimantan, Sumatra and Singapore and surrounding region which could continue to help with the haze situation.
6 The winds are expected to blow from the east-southeast or south-southeast on Thursday and Friday. While this could transport smoke haze from southern Sumatra, showers are forecast over the region which should help to lower the risk of haze.
Activity Guidelines
7 The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity.
