Dry weather prevailed over most parts of the southern ASEAN region overnight, except over the northern parts of Sumatra and the eastern parts of Borneo where showers were observed. Scattered 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, Singapore, Kalimantan, Sarawak and the southern and central parts of Sumatra. Moderate to dense smoke plumes were also observed to emanate from hotspot clusters detected in large parts of Kalimantan, as well as the central and southern parts of Sumatra. Many air quality stations in Peninsular Malaysia, Singapore, Borneo and Sumatra are reporting Unhealthy to Hazardous levels. The full extent of the hotspot situation could not be determined due to obscuration by thick smoke haze and cloud cover. The smoke haze situation at some parts of the region could not be fully determined due to cloud cover. It was relatively dry over the northern ASEAN region overnight, except for showers observed over the southern and eastern parts of the Mekong sub-region. The hotspot and smoke haze situation in the region remained subdued. In the coming days, dry conditions are expected over most parts of the southern ASEAN region, except over the northern parts of Borneo, as well as parts of Sumatra and Peninsular Malaysia where showers are forecast. The hotspot and smoke haze situation may improve in areas experiencing showers but also continue to stay elevated in areas experiencing prolonged periods of dry weather, with a continued risk of transboundary haze occurrence. The prevailing winds over the southern ASEAN region are forecast to blow from the east to south. On the other hand, wet weather is expected to persist over the northern ASEAN region, which helps to keep the hotspot and smoke haze situation subdued. The prevailing winds over the northern ASEAN region are forecast to be variable in direction.
