East and west Singapore join central region in recording unhealthy air quality amid haze
The 24-hour Pollutant Standards Index (PSI) hit 105 in the west and 102 in the east at 6am. The central region, which entered the unhealthy range a day earlier, recorded a reading of 123.
On Sunday, September 20, the air quality in Singapore's eastern and western regions dropped into the unhealthy range, joining the central region that had already reached that status. The 24-hour Pollutant Standards Index (PSI) measured 105 in the west and 102 in the east at 6am. The central region had earlier recorded a PSI of 123, indicating unhealthy air quality.
Over the past weeks, PSI readings have fluctuated between moderate and unhealthy ranges. On Tuesday, all five regions of Singapore recorded unhealthy air quality levels, marking the first occurrence since September 2019.
The National Environment Agency (NEA) issued a daily haze advisory on Saturday, predicting the 24-hour PSI to range from the high end of moderate to the middle of unhealthy. The agency warned of a potential risk of smoke haze affecting Singapore, with winds expected to blow from the east-southeast or southeast. Dry weather conditions in Kalimantan and southern Sumatra were also anticipated to persist, leading to smoke plumes from fires in those areas drifting towards Singapore.
