Haze forecast : Rain expected to keep Kalimantan, Sumatra smoke at bay till Nov 5

Showers over Singapore and the surrounding region are expected to keep the haze situation suppressed till at least Thursday (Nov 5).

In its daily haze situation update on Monday (Nov 2), the National Environment Agency (NEA) said winds are expected to blow mostly from the east or south-east.

While this could transport smoke haze to Singapore, the agency also pointed out that showers forecast over Sumatra, Kalimantan and the surrounding region are likely to help keep the haze situation suppressed.

The 24-hour Pollutant Standards Index (PSI) forecast is between 51 to 80 — in the moderate range.

At 7pm, hourly PM2.5 is in the normal band (0 - 55 µg/m3), with concentration readings between 21 and 25.

Meanwhile, PSI ranges from 63 in the eastern region to 81 in western Singapore.

In its fortnightly weather outlook for the first half of November issued on Oct 29 , the National Environment Agency said moderate to heavy thundery showers are expected over parts of the island on most days, with the showers extending into the evening on a few days.

预计新加坡及周边地区的阵雨将至少在周四（11月5日）之前抑制雾霾情况。

国家环境局（NEA）在周一（11月2日）发布的每日雾霾情况更新中表示，预计风向将主要从东或东南方向吹来。

虽然这可能会将烟雾带到新加坡，但该机构也指出，预计苏门答腊、加里曼丹及周边地区将有阵雨，这可能有助于抑制烟雾情况。

24 小时污染物标准指数 (PSI) 预测值在 51 到 80 之间——属于中等范围。

晚上 7 点，PM2.5 小时浓度处于正常范围内（0 - 55 µg/m3），浓度读数在 21 到 25 之间。

与此同时，新加坡东部地区的 PSI 指数为 63，西部地区的 PSI 指数为 81。

国家环境局在 10 月 29 日发布的 11 月上半月两周天气预报中表示，预计岛上大部分地区大部分时间将出现中到大雷阵雨，部分日子阵雨将持续到晚上。
