The PSI for Singapore as of 3pm today is at an unhealthy 127. Damn the haze! Besides providing hourly PSI updates, the National Environment Agency also provides the latest haze map. This map shows the area affected by haze over the region. Good for those who are planning an overseas trip during the long weekend. You may want to avoid places that are under the haze.
Update: Haze action plan to kick off when PSI hits 300. (Thanks P.K.)
