SINGAPORE: The haze returned to Singapore on Sunday (Oct 19), as the three-hour Pollutant Standards Index (PSI) crossed over to the unhealthy range at 11am with a reading of 104. It climbed to a high of 113 at 3pm before dropping to 70 at 9pm.

The National Environment Agency (NEA) said the haze was likely due to smoke from Sumatra, blown in by prevailing winds. It said there were 14 hotspots detected on Sunday in Sumatra, and 126 in Kalimantan. It said the low hotspot count for Sumatra was due to partial satellite coverage and cloud cover.

NEA added that hazy conditions are expected to persist overnight. For Monday, light prevailing winds are expected and there may be occasional haze. Thundery showers are expected in the late morning and early afternoon.

The 24-hour PSI is likely to hover between the high end of the moderate range and the low end of the unhealthy range. The agency advised healthy people to reduce prolonged or strenuous outdoor physical exertion.

The elderly, pregnant women and children should minimise such activities, while those with chronic lung or heart disease should avoid such activities.

Those who are not feeling well, and those with chronic heart or lung conditions, should seek medical attention.

SINGAPORE — After a brief respite last night the haze has returned in force this morning (Oct 20), with the three-hour Pollutant Standards Index (PSI) reading hitting 113 as of 9am, a figure in the unhealthy range.

Any reading over 100 up to 200 is considered in the unhealthy range. The elderly, pregnant women and children are advised to minimise prolonged or strenuous outdoor physical exertion, while those with chronic lung or heart disease should avoid such exertion altogether.

3-hour PSI hits high of 113 at 3pm
Today Online 19 Oct 14;

SINGAPORE — Singapore’s three-hour Pollutant Standards Index (PSI) hit 113 today (Oct 19) as of 3pm, in the unhealthy range.

Air quality gradually deteriorated over last night and this morning, leading to the peak at 3pm. Since then, the number has eased to 75 as at 8pm.

The National Environment Agency’s (NEA) daily haze situation update as of noon today states that haziness is expected to persist in the high end of the moderate range and low end of the unhealthy range for the rest of the day, with conditions "likely due to smoke haze from Sumatra, blown in by the prevailing winds".

Thundery showers are forecast in the afternoon for Singapore, and this may provide some relief from the hazy conditions.

A PSI reading of 101 to 200 falls within the unhealthy range, while a 51 to 100 reading is considered moderate.

The health impact of haze is dependent on one’s health status, the PSI level, and the length and intensity of outdoor activity. Reducing outdoor activities and physical exertion can help limit the ill effects from haze exposure.

Given the air quality forecast for the next 24 hours, the NEA said 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.
