Downgrade to Alert Level 1 for Mekong sub-region
Wet weather has prevailed over many parts of the Mekong sub-region in recent days, further reducing hotspot and smoke haze activities. A total of 119 and 116 hotspots were detected in the Mekong sub-region on 5 May 2026 and 6 May 2026 respectively from the NOAA-20 satellite.
As wet weather is forecast to continue over most of the Mekong sub-region in the coming weeks, the risk of transboundary haze occurrence is reduced. However, some areas of the sub-region may still experience drier weather conditions, and isolated hotspots with localised smoke plumes can develop.
