Latest Weather and Haze Situation

Showers were observed over Sumatra, Peninsular Malaysia and parts of Borneo, while dry conditions were observed elsewhere in the southern ASEAN region. Scattered hotspots were detected in Kalimantan, while few hotspots were detected in Sumatra. Moderate to dense smoke haze was observed over the southern parts of Kalimantan and Papua, as well as the central parts of Sulawesi. The full extent of the hotspot and smoke haze situation over the southern ASEAN region could not be determined due to extensive cloud cover. Wet weather continued over the northern ASEAN region, apart from the southeastern parts of the Mekong sub-region and the northern parts of the Philippines where it was relatively drier. Few to isolated hotspots were detected in the Mekong sub-region, but no significant smoke plumes were observed from satellite imagery.

Weather and Haze Outlook

In the coming days, showers are expected over parts of Peninsular Malaysia, Sumatra, Java and Borneo, while dry conditions are forecast elsewhere in the southern ASEAN region. The hotspot and smoke haze situation is likely to improve with the showers, with a reduced risk of transboundary haze occurrence. The prevailing winds over the southern ASEAN region are forecast to blow mainly from the east to southeast, except over the areas near the Equator where the winds are likely to be light and variable in direction. Wet weather is expected over the northern ASEAN region, apart from parts of northern Myanmar and the Philippines where relatively drier conditions are forecast. Isolated hotspots and smoke plumes may develop over areas experiencing prolonged dry conditions. The prevailing winds over the northern ASEAN region are likely to blow from the northeast to east, apart from the northwestern parts of the Mekong sub-region where the winds are expected to be light and variable in direction.
