NEA explains improvement in hazy conditions this weekend

SINGAPORE - The improvement in the hazy conditions this weekend was due to a temporary area free of dense haze upwind of Singapore and transient changes in the local wind conditions, the National Environmental Agency (NEA) said.

The 3-hour PSI dropped to 73 yesterday at 5pm - the lowest levels in days. The 3-hour PSI at 9am today stood at 101, just barely within the "unhealthy" range of 101 to 200 PSI.

The 24-hour PSI at 9am was 108 to 121, and PM2.5 concentration 111 to 141 micrograms per cubic metre.

However, NEA said that the 24-hour Pollutant Standards Index (PSI) is still expected to fall within the "very unhealthy" range of 201 to 300 for today.
