Upgrade of Alert Level 2 to Alert Level 3 for Kalimantan

The prevailing dry weather in Kalimantan has led to a further escalation of hotspot activities there in recent weeks. Persistent hotspot clusters with widespread moderate to dense haze have been detected mainly in the western, southern and central parts of Kalimantan. Based on surveillance by the NOAA-18 satellite, 401 and 333 hotspots were detected in Kalimantan on 4 September and 5 September respectively. Although the hotspot counts have since decreased, widespread haze continue to persist in large parts of Kalimantan. Some haze from Kalimantan has spread to the western parts of Sarawak and affected the air quality there.

In the coming days, the current dry weather conditions over Kalimantan are expected to persist. Under the prevailing wind conditions, transboundary smoke haze could continue to spread to Sarawak and other parts of the region.

Upgrade of Alert Level 2 to Alert Level 3 for Sumatra

In the past week, the prevailing dry weather has led to a further escalation of hotspot activities over Sumatra. Increasing hotspot clusters and widespread moderate to dense smoke haze have been detected in southern and central Sumatra. Based on surveillance by the NOAA-18 satellite, 222 and 380 hotspots were detected in Sumatra on 31 August and 1 September respectively. In recent days, the smoke haze from Sumatra has spread to some parts of the region including western Peninsular Malaysia and affected the air quality there.

In the coming days, the current dry weather conditions over southern and central Sumatra are expected to persist. Under the prevailing southeasterly to southerly wind conditions, transboundary smoke haze could continue to spread to some parts of the region.
