Latest Weather and Haze Situation

It was dry and cloudy over the southern ASEAN region today, apart from the northern and central parts of Sumatra, the northern parts of Borneo and parts of Peninsular Malaysia where there were some showers. Scattered to widespread hotspots were detected in the southwestern parts of Kalimantan and the southern and central parts of Sumatra, while few hotspots were detected elsewhere in the southern ASEAN region. Transboundary moderate to dense smoke haze was observed to cover over parts of Kalimantan and the southern parts of Sarawak. Moderate to dense smoke haze was also observed in the southern and central parts of Sumatra and the southern parts of Papua. Air quality stations in Kalimantan, the western parts of Sarawak and the central parts of Sumatra reported Unhealthy to Hazardous levels. The full extent of the hotspot situation over Kalimantan and Sumatra could not be determined due to obscuration by thick smoke haze and cloud cover, while the smoke haze situation over parts of the region could not be fully determined due to cloud cover. Dry conditions were observed over the Mekong sub-region, while showers were observed over the Philippines. Few to isolated hotspots were detected in the Mekong sub-region. Slight smoke plumes were observed over the central parts of Viet Nam.

Weather and Haze Outlook

Over the next few days, dry conditions are forecast over parts of the southern ASEAN region, except over parts of Peninsular Malaysia, Sumatra, Borneo and Java where showers are expected.

The prevailing winds over the southern ASEAN region are forecast to blow generally from the southeast to southwest, except over northern and eastern parts of Borneo where the winds are expected to blow from the north to northeast. Showers are forecast over the northern ASEAN region, except for relatively drier conditions over the northwestern and southeastern parts of the Mekong sub-region. Hotspot activity is likely to stay low. The prevailing winds over the northern ASEAN region are expected to blow from the northeast to east, apart from the northern parts of Mekong sub-region where the winds are forecast to be light and variable in direction.
