Latest Weather and Haze Situation

Dry conditions persisted over the southern ASEAN region today, except over parts of Peninsular Malaysia and the northern parts of Sumatra and Borneo where there were some showers. Widespread hotspots were detected in Kalimantan and Sumatra, while few hotspots were detected elsewhere in the southern ASEAN region. Moderate transboundary smoke haze was observed to cover parts of Peninsular Malaysia and the southern and central parts of Sumatra. Moderate to dense smoke haze was also observed over parts of Kalimantan. Air quality stations in Kalimantan as well as the southern parts of Sumatra and Peninsular Malaysia reported Unhealthy to Hazardous levels. The overall hotspot and smoke haze situation over the southern ASEAN region could not be fully determined due to cloud cover.

Weather and Haze Outlook

Over the next few days, dry weather is forecast to persist over the southern parts of Sumatra and Borneo. Showers are expected elsewhere in the southern ASEAN region. While showers may bring some respite to the hotspot and smoke haze situation, there remains a risk of transboundary haze occurrence especially over areas experiencing prolonged dry conditions. The prevailing winds over the southern ASEAN region are likely to blow from the southeast to southwest. Showers are forecast to prevail over the northern ASEAN region, which should keep the hotspot and smoke haze situation subdued. The prevailing winds over the northern ASEAN region are expected to be variable in direction, except over the central and eastern parts of the Mekong sub-region where the winds are likely to blow from the northeast.
