SINGAPORE, Sept 15 — The current hazy condition persists in Singapore, with the air quality continuing to stay at an unhealthy level.

The National Environment Agency (NEA) said today, the prevailing winds are forecast to blow from the southwest, and the current hazy conditions are expected to persist.

As of 8am today, the 24-hour pollutant standard index (PSI) stood at 122 - 150, and the three-hour PSI at 114.

A 24-hour PSI reading of above 100 indicates unhealthy air quality.

The haze situation could further deteriorate should the current unfavourable winds blow in denser haze from Sumatra.

Thundery showers are forecast for Singapore in early morning hours, but this may only bring a brief temporary respite to the hazy conditions. — Bernama
