NEA advises the public to use the 24-hour PSI forecast when planning outdoor activities and check the latest 1-hour PM2.5 readings for immediate activities.

Based on Sunday's PSI forecast, all members of the public can continue with their usual outdoor activities.

When 1-hour PM2.5 concentrations are in the elevated band, healthy individuals should reduce strenuous outdoor activities for the next hour.

Vulnerable groups, including children, elderly people, pregnant women and those with chronic heart or lung conditions, should avoid strenuous outdoor activities during that period.
