Is the haze episode over?

Singapore has been blanketed by haze starting from 14 June 2013. It's The island worst haze episode since the year 1997. The haze PSI hit a record high of 401 on 21 June.

However, the blue sky returns after 1 pm on 22 June without any warning. No rain, no strong wind. I came out of the kitchen, and was greeted by the pale blue sky when I looked up through the hall's bay window. Astonishing!

In the midst of people queuing frantically for N95 musks, the haze cleared off without leaving any trace or smell Amazing nature...
