Haze readings started to pick up gradually from 5am onwards.

The Asean Specialised Meteorological Centre (ASMC) said the haze was caused by smoke plumes over Sumatra 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 forecast to blow mainly from the south-east," it said.
