SINGAPORE - After several days of hazy weather, Singaporeans were treated to the welcome sight of blue skies on Thursday (Oct 8).

With air quality improving over the last 24 hours, the 24-hour Pollutant Standards Index (PSI) is currently in the moderate (51-100) band.

As of 11pm, the 24-hour PSI was between 73 and 82. The three-hour PSI stood at 86.

The National Environment Agency's (NEA) last update at 6pm on Wednesday also painted a positive outlook for the next 24 hours, with current conditions forecast to hold out as the 24-hour PSI forecast stays in the moderate range.

Prevailing winds are expected to be weak and to blow from the east or southeast.

There was also good news from Indonesia, as Foreign Affairs Minister Vivian Balakrishnan revealed on Facebook on Wednesday evening that the country - which has struggled to combat forest fires over the past month - had accepted Singapore's offer of assistance.

Mr Balakrishnan's post came after Singapore sent a formal request to Indonesia, requesting the names of errant companies involved in the haze.

Earlier on Wednesday, supermarket chains such as NTUC FairPrice, Sheng Shiong and Prime Supermarket pulled all Asia Pulp and Paper (APP) items off their shelves.

The items included popular brands such as Paseo.

APP, a Singapore-listed firm, and four Indonesian firms are believed to be the main culprits behind the raging fires in Kalimantan and Sumatra.
