Latest Weather and Haze Situation
Showers and cloudy conditions were observed over many parts of the southern ASEAN region this morning. Clusters of scattered hotspots were detected in the central and southern parts of Sumatra from overnight satellite imagery, as well as in parts of West and Central Kalimantan. Moderate to dense smoke plumes were observed to emanate from hotspots in the southern parts of Sumatra and Kalimantan. A few air quality stations in West and Central Kalimantan are reporting Hazardous levels, while stations in southern Sumatra, Sarawak and southern Peninsular Malaysia are reporting Unhealthy levels. The hotspot and haze situation could not be fully determined due to extensive cloud cover over the southern ASEAN region. Wet weather was also observed over most parts of the northern ASEAN region this morning. Hotspot counts remained low and no significant smoke plumes were observed.
Weather and Haze Outlook
Dry conditions are expected to continue over the southern and central parts of Borneo, as well as over the southern parts of Sumatra and parts of Java, Sulawesi and the Lesser Sunda Islands. Showers over other parts of the southern ASEAN region may provide some relief to the current hotspot and smoke haze situation, however there may still be a risk of transboundary haze occurring, especially over areas facing prolonged drier conditions. The prevailing winds over this region are forecast to blow from the southeast or south. Meanwhile, extensive wet weather is expected over the northern ASEAN region. The hotspot and haze situation over this region is expected to remain subdued. The prevailing winds over the Mekong sub-region are forecast to blow from the northeast while winds over the Philippines are forecast 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.
