Latest Weather and Haze Situation

Cloudy and dry conditions were observed over most parts of the Mekong sub-region and the Philippines today. Scattered hotspots were detected mainly in Cambodia with moderate smoke plumes also observed to emanate from clusters of hotspot in the northern and eastern parts of the country. Isolated hotspots were detected elsewhere in the sub-region with moderate smoke plumes observed to emanate from some of the hotspots in southern Viet Nam and northern Thailand. Slight localised smoke plume were also seen emitting from a hotspot in southern Myanmar. The full extent of the hotspot and smoke haze situation in the sub-region could not be determined due to cloud cover.

Wet weather continue to prevail over the southern ASEAN region and the hotspot activity remain subdued.

Weather and Haze Outlook

Over the next few days, dry conditions are expected to persist over most parts of the Mekong sub-region except over the southern and eastern parts of the sub-region. Hotspot and smoke haze activities may escalate in the fire- prone areas of the Mekong sub-region experiencing prolonged dry conditions. Meanwhile, wet weather is forecast to continue over the southern ASEAN region in the coming days and the hotspot activity in the region is expected to remain low. The prevailing winds north of the Equator are forecast mostly to be northeasterlies or easterlies while the winds south of the Equator are expected to be variable in direction.
