Haze readings started to increase gradually from 5am onwards.
The Asean Specialised Meteorological Centre (ASMC) attributed the haze to smoke plumes from Sumatra being blown north-west by prevailing winds.
“Under the prolonged dry weather, elevated hotspot activity and widespread hazy conditions are expected to persist over the fire-prone areas in southern and central Sumatra and southern Kalimantan.
“The prevailing winds are forecasted to blow mainly from the south-east,” it stated.
