Latest Weather and Haze Situation
Dry and cloudy conditions prevailed over most parts of the northern ASEAN region except for isolated showers over some parts of the northern and eastern Mekong sub-region. Scattered hotspots were detected in Cambodia, Thailand and Lao PDR while isolated hotspots were detected elsewhere in the Mekong sub- region. Widespread moderate to dense transboundary smoke plumes were observed emanating from clusters of hotspots in parts of northern Thailand drifting towards the northeast into northern Lao PDR, from northern Lao PDR into northern Viet Nam, as well as from northwestern Cambodia into eastern Thailand. Moderate smoke plumes were also observed to emanate from clusters of hotspots in parts of central Myanmar, as well as central and southern Cambodia. Moderate smoke haze was also observed over parts of southern Lao PDR and central Viet Nam. Extensive cloud cover over northern and eastern parts of the Mekong sub-region made it hard to discern the full extent of the hotspot and smoke haze situation there. Many air quality stations in the northern and eastern Mekong sub-region reported air quality at Unhealthy levels to Very Unhealthy levels.
Elsewhere in the ASEAN region, showers were observed except over parts of central Sumatra and northeastern Peninsular Malaysia where it was relatively dry. Few hotspots were detected in Kalimantan and Peninsular Malaysia with slight localised smoke plumes observed to emanate from a few hotspots in eastern Peninsular Malaysia.

Weather and Haze Outlook
In the coming days, dry conditions are expected to persist over the central and western parts of the Mekong sub-region while increased showers are forecast over the rest of the sub-region. Some improvement to the hotspot and haze situation may be expected with the increased rainfall although transboundary smoke haze and elevated hotspot activities are expected to continue, especially in the northwestern and central parts of the sub-region. The prevailing winds north of the Equator are forecast mostly to blow from the east or south with the exception of the Mekong sub-region where the winds are expected to be light and variable in direction.
Meanwhile, shower activities are expected over the southern ASEAN region in the coming days. The hotspot activity in the region is expected to remain subdued, however isolated hotspots and localised smoke plumes may still occur in the dry areas. The winds south of the Equator are forecast to be light and variable in direction.
