If you are living or working in the eastern, southern and western regions of Singapore, and have observed lowered visibility and a burning smell, that's because PM2.5 concentration levels have hit the high band in these areas.
At 1pm on Wednesday (Oct 14), PM2.5 ranged from 88 in northern Singapore to 195 in the western region.
Concentration readings in eastern (160), southern (173) and western (195) Singapore are in the high band.
Meanwhile, the 24-hour Pollutant Standards Index (PSI) remains in the unhealthy range across Singapore, with western Singapore recording the highest reading of 146, closely followed by the eastern (145) and western (146) regions.
When PM2.5 readings are in the high band, healthy persons should avoid strenuous outdoor activities for the next hour.
Those who are vulnerable or have lung and heart ailments are advised to avoid all outdoor activity for the next hour.
Weather, PSI forecast
According to the National Environment Agency's weather microsite, thundery showers are forecast mainly over northern, western and central Singapore in the afternoon.
But the agency also pointed out in its daily haze situation update on Tuesday evening that with dry conditions expected to persist over parts of southern Sumatra and Kalimantan, coupled with the prevailing winds, smoke haze may still drift towards Singapore.
The city state's 24-hour PSI forecast till this evening is expected to remain in the unhealthy range.
Members of the public should check the latest PM2.5 readings before participating in outdoor activities.
如果您居住或工作在新加坡的东部、南部和西部地区，并且观察到能见度降低和烧焦的气味，那是因为这些地区的 PM2.5 浓度水平已达到较高水平。
10 月 14 日星期三下午 1 点，PM2.5 浓度从新加坡北部的 88 到西部地区的 195 不等。
新加坡东部（160）、南部（173）和西部（195）的浓度读数处于高位。
与此同时，新加坡的 24 小时污染物标准指数 (PSI) 仍然处于不健康范围内，其中新加坡西部地区的读数最高，为 146，东部地区 (145) 和西部地区 (146) 紧随其后。
当 PM2.5 读数处于较高水平时，健康人群应在接下来的一个小时内避免剧烈的户外活动。
建议体弱者或患有肺部和心脏疾病的人在接下来的一个小时内避免所有户外活动。
天气、PSI预测
根据国家环境局的天气微网站预测，下午新加坡北部、西部和中部地区将主要出现雷阵雨。
但该机构在周二晚间的每日雾霾情况更新中也指出，由于预计苏门答腊南部和加里曼丹部分地区将持续干燥，再加上盛行风向，烟雾仍可能飘向新加坡。
预计该城市州未来24小时的空气污染指数（PSI）将持续到今晚，并处于不健康水平。
公众在参加户外活动前应查看最新的PM2.5读数。
