SINGAPORE - Skies remained grey on Monday (Oct 26) as the Pollutant Standards Index (PSI) stayed in the unhealthy range.
As of 5pm, the 24-hour PSI was 138 to 167 which is in the unhealthy range (101-200). The three-hour PSI, which is not linked to health advisories, was 155.
The National Environment Agency (NEA) said in its haze update on Sunday evening that hazy conditions and reduced visibility are expected on Monday.
With prevailing winds forecast to blow from the east or south-east, air pollution levels are expected to be in the mid to high sections of the unhealthy range.
The haze could deteriorate should denser smoke be blown in from Indonesia's Kalimantan region, NEA added.
Healthy persons are advised to reduce prolonged or strenuous outdoor physical exertion. The elderly, pregnant women and children should minimise prolonged or strenuous outdoor physical exertion, while those with chronic lung or heart disease should avoid prolonged or strenuous outdoor physical exertion.
Persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
