Everything you need to know about PSI hitting 471 in the west yesterday

The haze struck back suddenly with no warning at 10pm last night with the west and south of Singapore taking a huge brunt of the attack. The 1-hour PM2.5 level in the west of Singapore was 442 and 299 in the south.

It was said that if the PSI level in the west remains that high for 23 more hours, it will be viewed as “Hazardous”, which most likely means the closure of schools in the west.

To the disappointment of school kids and teachers alike, I’m sure, the PSI level fell by more than half by the time the clock struck 12, with 1-hour PM2.5 level 262 and 105 in the west and south respectively despite rising to 471 and 301 at 11pm.

The haze has never came in at a more inopportune time, especially with experts saying that the hazy season might extend all the way till next year, depending on when Indonesia will experience heavy rainfall.

Apparently, the situation in Indonesia has spiraled out of control, even after Indonesia has finally accepted the help of both the Malaysian and Singaporean Governments who had sent in aircrafts for cloud seeding and water bombing operations and teams of firefighters.

Dr Vivian Balakrishnan posted on his Facebook on 19 Oct 2015, saying that he had breakfast with Luhut Pandjaitan, Indonesia’s Coordinating Minister for Political, Legal and Security Affairs. He mentioned that among the many things he had discussed with Pak Luhut, one of the things mentioned was the ongoing haze situation, namely the list of names of errant companies which has contributed to the haze. He said that they were still waiting on the list of names and hoped to receive it soon to take legal actions against these companies.

So, last thing to say before I end off, does anyone else find the 3-hour psi redundant? It’s an average over 3 hours of psi level, which we understand will be able to give a more accurate view of the situation; but knowing that and seeing 96 reported as the 3-hour psi while looking at a scene that looks right at home high up in the mountains in Genting really makes one mad, no matter if we understand the reasoning behind the calculations or not, doesn’t it?

Here’s why a 4-day workweek might finally really be possible in Singapore soon:
