SINGAPORE — Slightly hazy conditions can still be expected tomorrow (Oct 10), with air quality possibly entering the unhealthy range.
The 24-hour Pollutant Standards Index (PSI) is expected to be in the high end of the moderate range and may enter the low end of the unhealthy range over the next 24 hours. It may reach the mid-section of the unhealthy range if winds are unfavourable, said the National Environment Agency (NEA) in an update this evening.
The NEA said that the slight deterioration in haze and visibility today was due to prevailing southeasterly winds blowing in the haze from the surrounding region. Conditions are expected to persist for the rest of the day. The haze has been in the moderate range and gradually improving since 10pm on Wednesday when the 24-hour PSI reading was 80-99.
As at 7pm today, the 24-hour PSI was in the moderate range at 83-95 while the 3-hour PSI stood at 84.
Thirteen hotspots were detected in Sumatra today, although NEA said the low count was due to cloud cover over parts of Sumatra. Yesterday, 19 hotspots were detected. In southern and central parts of Sumatra, widespread haze is still persisting while some haze was also observed to have spread to the surrounding sea areas south of Singapore, said the NEA.
Given the air quality forecast for the next 24 hours, healthy persons should reduce prolonged or strenuous outdoor physical exertion, said the NEA. 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.
