Weather and Haze Outlook

In the coming days, isolated showers are forecast to continue over parts of the northern ASEAN with a possibility of persistent dry conditions in the western and southeastern parts of the Mekong sub-region and the northern parts of the Philippines. Escalated hotspot activity and smoke plumes may continue with a risk of transboundary haze occurrence, especially in areas of the sub- region still facing prolonged drier conditions. The prevailing winds over most parts of the Mekong sub-region are forecast to blow from the southwest while winds over the Philippines and Viet Nam are forecast to blow mainly from the east.

Meanwhile, over the southern ASEAN region, scattered showers are forecast with the exception of relatively drier conditions over the eastern parts of Borneo and the Lesser Sunda Islands. Hotspots and localised smoke plumes can occur in areas experiencing drier conditions. The prevailing winds over the southern ASEAN region are forecast to be light and variable in direction, except for the prevailing winds over Sulawesi, the Lesser Sunda Islands and Java where winds are forecast to blow from the southeast.
