Update for today: The 3-hour PSI reached 401 around lunch time. In plain English, it's potentially lethal for the ill and elderly if they were outside during this time. A lot of residential and commercial buildings are now also smelling smoke inside as well, so about the only way to avoid it now would be getting out of the country. I would also imagine the airport to be a little bit hazy as well. Visibility was well below 1km for most of the morning.
N95 masks and air purifiers continue to be out of stock in the vast majority of places. Any places offering sales of such products are completely swamped. A groupon-like site finished an allocation of N95 masks in hours. Retail freight forwarders are also offering free upgrade to express shipping for this type of products being shipped from the US.
On the bright side, there are less than half the hotspots in Sumatra from the peaks earlier this week, and over the past 5 hours, the PSI has returned to levels that are much more acceptable and generally non-life-threatening for the vast majority of the population.

For those hanging out in SIN, the 3-hour gives the most up-to-date data regarding the haze conditions.
For those who aren't in the country, but want to keep an eye on the situation, scroll down to the 24-hour readings, which would be more useful as a summary.
