  "account": "On September 9, the 24-hour Pollutant Standards Index (PSI) in central Singapore entered the unhealthy range, reaching 106 by 9am on September 10, according to the National Environment Agency (NEA). Other areas of Singapore, such as the north (75), south (78), east (83), and west (86), remained in the moderate range at the same time. The overall PSI in Singapore was thus categorized as moderate to unhealthy, ranging from 75 to 106 at 9am on September 10.\n\nThe 24-hour PSI represents air quality over the past 24 hours, and the NEA advises the public to use it for planning their outdoor activities the following day. For immediate outdoor activities, the NEA recommends checking the 1-hour PM2.5 concentration readings. As of 9am on September 10, the 1-hour PM2.5 concentration was still in the normal range.\n\nIn a Sep. 9 advisory, the NEA forecasted that the 24-hour PSI would likely be in the high moderate to low unhealthy range. The agency stated that dense smoke plumes from fires in southern and central Sumatra and Kalimantan continue to produce smoke haze drifting towards Singapore. The NEA also mentioned that while some showers are expected over central and northern Sumatra in the coming days, dry conditions are anticipated to persist over Kalimantan and southern Sumatra. Prevailing winds from the southeast or south indicate a continued risk of smoke haze affecting Singapore if the fires persist. The NEA has been issuing daily advisories via its website to help inform the public about the situation and plan their schedules accordingly.",
