Air quality in Singapore is expected to be in the high end of the moderate range and may enter the low end of the unhealthy range tomorrow (Nov 6), the National Environment Agency (NEA).
This may mark the end of a 9-day reprieve for Singapore, as the nation has been experiencing moderate air quality since last Wednesday.
For tomorrow, the prevailing winds are forecast to be weak, blowing from the south or southwest. Slight haze and reduced visibility conditions can be expected if winds are unfavourable.
As of 7pm today, the 24-hr PSI was in the Moderate range at 76-88 and the 1-hr PM2.5 was 42 – 57µg/m3.
Some parts of southern Sumatra continue to be affected by moderate haze, according to the NEA, with 55 hotspots detected on the Indonesian island compared to six yesterday. Some haze has been observed to spread to the sea areas south of Singapore.
In Singapore, thundery showers are forecast in the late morning and early afternoon.
Given the air quality forecast for the next 24 hours, the NEA has advised healthy persons 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. Those who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical attention.
