Latest Weather and Haze Situation
Dry weather persisted over parts of the southern ASEAN region, except over the western parts of Borneo and parts of northern Sumatra and Peninsular Malaysia where there were showers. Scattered hotspots were detected in the southeastern parts of Kalimantan, while few to isolated hotspots were detected elsewhere in the southern ASEAN region. Moderate to dense smoke plumes were observed over the southern parts of Kalimantan and the central parts of Sumatra. Moderate smoke haze was observed over the southern parts of Papua and 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. The northern ASEAN was relatively dry overnight, except for some showers over the southern parts of the Mekong sub-region. Hotspot activity remained low.
Weather and Haze Outlook
Over the next few days, dry weather is forecast over parts of the southern ASEAN region, apart from parts of Peninsular Malaysia, Sumatra, Java and Borneo where showers are expected. While showers may bring some improvement, the hotspot and smoke haze situation is likely to remain elevated especially over areas experiencing prolonged dry weather, with a risk of transboundary haze occurrence. The prevailing winds over the southern ASEAN region are forecast to blow mainly from the southeast, except over the areas near the Equator where light and variable winds are expected. The northern ASEAN region is likely to stay wet, apart from the northern parts of Myanmar and the Philippines where it is forecast to be relatively drier. Isolated hotspots and smoke plumes may develop over areas experiencing prolonged dry conditions. The prevailing winds over the northern ASEAN region are expected to blow from the northeast to east, apart from the northwestern parts of the Mekong sub-region where the winds are likely to be light and variable in direction.
- All maps are to be used solely for displaying meteorological/geophysical information, and not for any other purpose. All maps are not to scale and for illustrative purpose only.
- The hotspots depicted on the map are derived from the NOAA satellite and they represent locations with possible fires. Hotspots may go undetected due to cloudy conditions or incomplete satellite pass.
- At Alert Level 0 and Alert Level 1, the regional haze situation is updated once a day at 0900 UTC. The regional haze situation is updated more frequently at 0300 UTC and 0900 UTC upon activation of Alert Level 2 or Alert Level 3. Updates at 0300 UTC display hotspot information from night-time passes of the NOAA-20 satellite. Fewer hotspots were typically detected at night as fire activities usually peak during the day.
- Reprocessed satellite data will be availed at a later timing. The hotspot information derived from satellite data reprocessed may differ slightly from that received near real-time but reprocessing is necessary for better quality data.
