Air quality in Singapore has returned to moderate levels after a period where levels in the central region reached unhealthy ranges. The National Environment Agency (NEA) reported this improvement on Saturday, but cautioned that the risk of smoke haze persists. Forecasts predict the 24-hour Pollutant Standards Index (PSI) will fluctuate between high-moderate and low-unhealthy levels. Residents should remain vigilant and monitor updates from the NEA. While conditions currently allow for a return to normalcy, the potential for worsening haze remains a concern. The NEA continues to monitor the situation and will provide further advisories as needed.
