Latest Weather and Haze Situation
Dry weather persisted over the southern ASEAN region today, except for some showers over parts of northern and central Sumatra, southern Peninsular Malaysia as well as northern and eastern Borneo. Widespread hotspots were detected in Kalimantan and Sumatra, while few hotspots were detected elsewhere in the southern ASEAN region. Moderate to dense transboundary smoke haze was observed over parts of Sumatra, Peninsular Malaysia, Singapore, Kalimantan and the western parts of Sarawak. Moderate to dense smoke haze was also observed over Papua and Sulawesi. Air quality stations in Kalimantan, Peninsular Malaysia, Singapore, Sumatra and the western parts of Sarawak reported Unhealthy to Hazardous levels. The full extent of the hotspot and smoke haze situation over the southern ASEAN region could not be determined due to cloud cover. Showers continued over the northern ASEAN region, apart from the northern parts of the Mekong sub-region where relatively drier conditions were observed. Hotspot activity over the northern ASEAN region stayed low.
Weather and Haze Outlook
Over the next few days, dry conditions are likely to persist over the southern ASEAN region, apart from Peninsular Malaysia, the northern parts of Sumatra and the northern parts of Borneo where isolated showers are expected. The hotspot and smoke haze situation may improve over areas experiencing showers, but remain elevated over areas experiencing prolonged dry conditions, with a continued risk of transboundary haze occurrence. The prevailing winds over the southern ASEAN region are forecast to blow mainly from the southeast to south. Showers are likely to continue over the northern ASEAN region, except over the northeastern parts of the Mekong sub-region where relatively drier conditions are expected. The hotspot and smoke haze situation is forecast to remain subdued. The prevailing winds over the northern ASEAN region are likely to blow from the northeast to southeast, except over the northern and eastern parts of the Mekong sub-region where the winds are expected 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.
