SINGAPORE — Slightly hazy conditions could hit Singapore sporadically over the next two weeks due to prevailing wind conditions and periods of consecutive dry days that are usually seen during the current South-west Monsoon season.

Winds are expected to continue to blow from the south-southeast or the south-west — where Sumatra lies — the regular fortnightly weather outlook the National Environment Agency (NEA) posted on its website yesterday showed.

In its daily haze advisory, the NEA said seven hot spots were detected in Sumatra yesterday, down from the 80 spotted on Monday when the Pollutant Standards Index (PSI) crept into the low end of the unhealthy range.

Nevertheless, widespread smoke haze was observed over the southern and central areas of Sumatra, it noted.

Readings for the 24-hour PSI fluctuated yesterday, but remained in the moderate range.

The western part of the island continued to log higher PSI levels than the rest of Singapore, peaking at 94 at around 1am.

The NEA cited a change in wind direction to be the reason for the lower PSI readings yesterday, compared with Monday.

The overall air quality for today is expected to be in the moderate range, with prevailing winds blowing from the south-east and expected showers in the afternoon. “Given the air quality forecast for the next 24 hours, everyone can continue with normal activities,” said the NEA. TAN SHI WEI
