‘Low’ odds of haze in Singapore over next few days: NEA

SINGAPORE — The likelihood of Singapore being affected by transboundary haze is low over the next few days, the National Environment Agency (NEA) said on Monday (Sept 5).

This is because prevailing light winds are expected to continue blowing from the south-west or west, while showers are forecast over parts of Sumatra and the surrounding region.

Just one hotspot was detected in Sumatra on Monday, and there was no visible smoke plume or haze observed, said the NEA. However, the low hotspot count was due to a partial satellite pass and cloud cover, the NEA added.

As of 5pm on Monday, the 24-hour Pollutant Standards Reading (PSI) reading was 63-78, in the moderate range, and the 1-hour PM2.5 concentration was 5-17µg/m3 in the normal band.

The PSI for the next 24 hours is forecast to be in the moderate range, said the NEA, with the 1-hour PM2.5 concentration expected to stay in the normal band over the same time period.
