PSI at 290 in Tekong

Oh my god the Pollution Standard Index (PSI) is 290!! How did it jump from 190 to 290 in an hour!? Anyway the haze here in Tekong is crazy.. Everyone in my bunk is celebrating because outdoor training was cancelled and the 12km Route March tomorrow would probably be cancelled too.. Wow this is like a dream come true.  And everyone here is hoping for early bookout.. Okay gotta go to sleep now.. Hopefully the PSI remains this high tomorrow!!
