SINGAPORE : The haze is back in Singapore, with the southwesterly winds blowing in the smoke from the fires in Sumatra.

The National Environment Agency (NEA) said the 3—hour PSI reading on Tuesday climbed from 78 at 6pm to 84 at 8pm before dropping to 61 at 11pm. Though the readings are still in the moderate range, the condition has worsened from the 24—hour reading of 56 at 4pm.

The 24—hour PSI is a measure of the air quality over a period of 24 hours. It is updated at 4pm daily. The 3—hour PSI reading is a measure of the air quality over a period three hours. It is updated on the hour.

A PSI reading of above 100 is considered unhealthy.

The NEA said the latest satellite pass detected 202 hotspots in Sumatra, mainly in the provinces of South Sumatra, Jambi and Riau.

The winds are expected to remain southwesterly to westerly from the evening to Wednesday, and showers with thunder are expected in the late morning and afternoon on Wednesday.

NEA said the showers should help to mitigate some of the smoke haze, but there is still a possibility that some slight haziness may remain over the next few days.

The agency is monitoring the smoke haze situation closely and will provide updates should the air quality deteriorate.

Members of the public may also call the NEA Call Centre at 1800—CALL NEA (1800—2255—632) or access www.nea.gov.sg for any feedback or update on the situation.
