  "account": "On September 5, the air quality in the west of Singapore reached an unhealthy level of 102 on the PSI, joining the Central region which had already been experiencing poor air quality. The 24-hour PSI for Central region reached 119, while the East dipped to 99 and West to 102. Air quality is considered unhealthy when the PSI falls between 101 and 200, and during this time, the National Environment Agency advises the public to reduce outdoor activities. The West crossed the 101 PSI threshold around midnight, according to The Straits Times. The East had already entered the unhealthy range at around 9pm on September 4 and remained there until the morning of September 5. This marks the Central region's first experience with unhealthy air quality in over a year, since October 2023. The last time Singapore faced unhealthy air due to haze was during this period. On September 4, the NEA issued an advisory that the haze could persist until September 5, with air quality expected to fluctuate between moderate and unhealthy levels. Smoke plumes emanating from fires in southern and central Sumatra and various regions of Kalimantan were observed drifting towards Singapore. With the forecast calling for dry conditions in the coming days, Singapore may continue to be affected by transboundary haze if wind direction remains unchanged as the fires persist.",
