Downgrade to Alert Level 2 for Mekong sub-region
Shower activities over the Mekong sub-region have increased in recent days under the inter-monsoon conditions. The increased rainfall has contributed to a reduction in hotspot counts and some improvement to the smoke haze situation in the sub-region. Nevertheless, elevated hotspot activity and transboundary haze may still be observed over parts of the Mekong sub-region where drier conditions are expected.
A total of 585 and 178 hotspots were detected in the Mekong sub-region on 22 April 2026 and 23 April 2026 respectively from the NOAA-20 satellite. The overall hotspot and smoke haze situation in the sub-region is anticipated to improve further as increased rainfall is forecast across the area in the weeks ahead.
