Weather and Haze Outlook

Dry weather is expected to persist over the northern parts of the Mekong sub-region in the coming days, while isolated showers are forecast elsewhere in the Mekong sub-region and the Philippines. Although the expected showers may bring some improvement to the region, the hotspot and smoke haze situation is likely to continue over the drier areas especially over the northern parts of the Mekong sub-region, with some chance of transboundary haze occurrence. The prevailing winds over the northern ASEAN region are expected to blow from the south to southwest, except over the Philippines where winds are forecast to blow from the east.

Showers are likely to continue over the southern ASEAN region, which should keep the overall hotspot and smoke haze subdued. The prevailing winds over the southern ASEAN region are expected to be light and variable in direction.
