SINGAPORE-Hazy conditions and reduced visibility are expected to persist on Tuesday, the National Environment Agency (NEA) said in an update at 6pm on Monday.

Thundery showers are forecast in the afternoon, but may only bring a temporary respite to the grey skies.

As at 9pm on Monday, the 24-hour PSI was 138-170, in the unhealthy range.

With prevailing winds expected to blow from the east or southeast, air quality for the next 24 hours is expected to be within the mid to high sections of the Unhealthy range.

Lower hotspot counts of 11 and 84 were detected in Sumatra and Kalimantan respectively, compared to three and 212 on Sunday. This is due to to partial satellite pass and cloud cover over parts of Sumatra and Kalimantan. However, moderate to dense haze is still persisting in parts of central and southern Sumatra and Kalimantan. Some haze from Kalimantan continues to spread to our surrounding sea areas.

Given the air quality forecast for the next 24 hours, healthy persons should 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.
