SINGAPORE - The air on Monday (Sept 26) is expected to be clear, with the 24-hour Pollutant Standards Index (PSI) forecast to be in the Moderate range.

This is because the prevailing winds are likely to blow from the west-southwest or west, and thundery showers are expected in the morning for Singapore.

The 1-hr PM2.5 concentration over the next 24 hours is expected to remain in Band I (Normal), the National Environment Agency said in its haze advisory on Sunday (Sept 25).

For the next few days, the prevailing winds are forecast to blow from the west-southwest or west-northwest. Showers are expected over parts of central and southern Sumatra.

The likelihood of Singapore being affected by transboundary haze is low, the agency added.

On Sunday, there were thundery showers over many parts of Singapore in the early morning and fair weather conditions are expected for the rest of the day.

As at 5pm, the 24-hour PSI was 53-59, in the Moderate range, and the 1-hr PM2.5 concentration readings were 10-20 µg/m3, in Band I (Normal).

A total of nine hot spots were detected in Sumatra on Sunday, the NEA said. There were no visible smoke plumes or haze observed.

Given the air quality forecast for the next 24 hours, people can continue with normal activities, the agency added. Those who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
