Air quality in Singapore’s central region back in unhealthy range as PSI hits 102
NEA said air quality is forecast to be in the moderate and unhealthy range.
Singapore's air quality in the central region has once again reached the unhealthy range, according to a 24-hour Pollutant Standards Index (PSI) reading of 102 on Sept 14. The National Environment Agency (NEA) reported the PSI at 91 in the east and west, 82 in the south, and 79 in the north at 12pm. The unhealthy range, marked by PSI readings between 101 and 200, was first reached two weeks ago on Sept 4, with a PSI of 101 in central Singapore.
Since Sept 11, PSI readings across Singapore have returned to the moderate spectrum and have remained there. This marks the first time in over two years that the PSI in Singapore has reached unhealthy levels due to haze. The NEA warned of the risk of haze between June and October due to El Nino and the Indian Ocean Dipole. The agency forecast moderate to lower end of unhealthy air quality for the next 24 hours, with dense smoke plumes from fires in Kalimantan and southern Sumatra continuing to be observed.
Showers are expected over northern Sumatra and north-western Borneo, while dry weather is forecast over Kalimantan and central and southern Sumatra. The NEA advises the public to reduce outdoor activities when the PSI is in the unhealthy range.
