Singapore haze situation improved in the weekend thanks to winds

After horrific levels of PSI in Singapore, this weekend brought us some relatively fresh air. Is haze over? Unfortunately the answer is no. The reason we had low PSI was winds pushing heavy smoke away from Singapore rather than a decrease in the forest fires:

There has been an improvement in air quality since last night, and this improvement has been sustained this morning. As at 12 noon today, the 24-hour PSI is 88-98 and the 24-hr PM2.5 is 81-102 ug per meter cube.

The improvement in the air quality is due to a change in the direction of the low level winds over Singapore from south-westerly to southerly, since last night.

The 2-hour PSI for the rest of today is revised to be in the unhealthy band (101-200).
