Haze expected to persist for rest of today: NEA

SINGAPORE — Yesterday’s (Nov 2) hazy conditions are expected to persist for the rest of today, owing to smoke haze from southern Sumatra, blown in by the prevailing southerly winds, the National Environment Agencey (NEA) said.

Yesterday, the three-hour Pollutant Standards Index breached the unhealthy mark at 3pm and readings edged up steadily to hit 127 by 9pm, before receding slightly to 126 at 10pm.

As of 7pm today, the 24-hour Pollutant Standards Index (PSI) stands in the 92-108 range. Any reading over 100 up to 200 is considered unhealthy.

The NEA said the 24-hr PSI for Singapore is expected to remain in the high-end of the Moderate range and the low-end of the Unhealthy range.

The NEA also advises that prolonged or strenuous outdoor physical exertion should be reduced for healthy persons, the elderly, pregnant women and children, as well as those with chronic lung or heart disease.
