Due to elevated levels of the particle PM2.5 from 10pm last night to 7am this morning in the Western region of Singapore, the 24-hour PSI reading for that region has hit the “unhealthy” range.
According to the National Environment Agency (NEA), the area read 106 at 2pm today, while the other parts of Singapore fell between 80 and 86.
A PSI reading of 0-50 is considered “good”, 51-100 is still “moderate”, while 101-200 is classified as “unhealthy”.
NEA says the elevated levels of PM2.5 are most likely due to the hotspots in South Sumatra that have been detected over the past three to four days. Those the number of hotspots detected so far has been lower than previous days, the count is not considered complete due to partial satellite coverage. NEA warns that the hotspots are likely to persist and the 24-hour PSI for Singapore is expected to fluctuate between the high-end of the “moderate” range and the low-end of the “unhealthy” for the rest of the day.
