Singapore's 24-hour Pollutant Standard Index (PSI) is expected to remain within the high moderate to low unhealthy range, the National Environment Agency (NEA) said in its daily update on Saturday (Sept 5).
The agency began providing daily updates from Friday, after 24-hour PSI entered into the unhealthy range for the first time since Oct 8, 2023, with the central region recording a reading of 103 that morning.
In its second forecast on Saturday evening, NEA noted that most parts of the surrounding region remained dry.
Its satellite picture at 2.42pm indicated that moderate to dense smoke plumes over the southern and central parts of Sumatra and various parts of Kalimantan are continuing to drift towards Singapore.
This, coupled with expected dry conditions over Singapore and the region in the coming days, and the prevailing south-easterly or southerly winds, means the city state may continue to be affected by transboundary haze should the fires remain active, the agency stated.
It also forecast the 24-hour PSI for Singapore to be in the higher end of the moderate to the lower end of the unhealthy range.
Checks on the NEA haze microsite at 6pm indicated that the 24-hour PSI reading of 104 for the central region remains in the unhealthy range.
Across the north, east, south and west regions, PSI remains in the moderate range, with the west region recording a reading of 92 — bordering on unhealthy range.
NEA said that the health impact of haze is dependent on one's health status, the PSI level, and the length and intensity of outdoor activity.
It advised those who are planning to conduct or participate in outdoor activities now to check the 1-hour PM2.5 concentration readings and vulnerable persons guide.
Meanwhile, those who are planning outdoor activities for the next day should use the 24-hour PSI forecast and the corresponding health advisories for planning.
新加坡国家环境局 (NEA) 在周六（9 月 5 日）的每日更新中表示，新加坡 24 小时污染物标准指数 (PSI) 预计将保持在高、中、低不健康范围内。
该机构从周五开始提供每日更新，此前 24 小时 PSI 指数自 2023 年 10 月 8 日以来首次进入不健康范围，当天上午中部地区的读数为 103。
新加坡国家环境局（NEA）在周六晚间发布的第二份天气预报中指出，周边地区大部分地区仍然干燥。
下午 2 点 42 分的卫星图像显示，苏门答腊岛南部和中部以及加里曼丹岛部分地区的中等至浓烟正继续向新加坡飘去。
该机构表示，鉴于未来几天新加坡及周边地区预计将出现干燥天气，且盛行东南风或南风，如果火势持续蔓延，新加坡可能会继续受到跨境烟霾的影响。
该机构还预测，新加坡的 24 小时 PSI 指数将处于中等偏高水平至不健康水平的较低水平。
下午 6 点对国家环境局雾霾微网站的检查显示，中部地区的 24 小时 PSI 读数为 104，仍处于不健康范围内。
在北部、东部、南部和西部地区，PSI 指数仍处于中等水平，其中西部地区的读数为 92，接近不健康水平。
新加坡国家环境局表示，雾霾对健康的影响取决于个人的健康状况、空气污染指数（PSI）以及户外活动的持续时间和强度。
它建议计划进行或参与户外活动的人们查看 1 小时 PM2.5 浓度读数和弱势群体指南。
同时，计划第二天进行户外活动的人们应该参考 24 小时 PSI 预报和相应的健康建议进行规划。
