Latest Weather and Haze Situation
Dry conditions were observed to prevail over many parts of the Mekong sub-region today. Widespread hotspots were detected in many parts of Cambodia and scattered hotspots were detected mainly in the central parts of Myanmar. A few to isolated hotspots were detected elsewhere in the northern ASEAN region. Moderate to dense smoke plumes were observed to emanate from hotspots in Cambodia and the southern parts of Lao PDR. Smoke plumes from the southern parts of Lao PDR were observed to drift southwards into the northeastern parts of Cambodia. Smoke plumes from the western parts of Cambodia were observed to drift westwards into the central parts of Thailand. Moderate smoke haze was also observed in the central and northern parts of Myanmar. The full extent of the hotspot and smoke haze situation could not be fully determined due to cloud cover over the central and eastern parts of the Mekong sub-region.
Isolated showers were observed over the southern ASEAN region today except for relatively drier conditions observed over parts of Peninsular Malaysia and Sumatra. A few hotspots were detected mainly in the western parts of Peninsular Malaysia as well as the northern and central parts of Sumatra. A few slight to moderate localised smoke plumes were observed to emanate from hotspots in the central parts of Sumatra. A localised smoke plumes was also observed in the western parts of Kalimantan and southern and central parts of Peninsular Malaysia.
Weather and Haze Outlook
In the coming days, dry conditions are forecast to persist over most parts of the Mekong sub-region with the exception of showers forecast over parts of Viet Nam. Wet weather is forecast to continue over parts of the Philippines. The hotspot and smoke haze situation can remain escalated in areas of the Mekong sub-region facing prolonged drier conditions with a risk of transboundary haze occurrence. The prevailing winds over the northern ASEAN region are expected to weaken and blow mainly from the northeast to east while winds over Myanmar are forecast to blow from the south.
For the southern ASEAN region, dry conditions are forecast over parts of Peninsular Malaysia, the central parts of Sumatra as well as the western pars of Borneo. Showers are expected to continue over the rest of the southern ASEAN region. Isolated hotspots and localised smoke plumes can emerge in areas facing relatively drier conditions. The prevailing winds in the southern ASEAN region are forecast to blow from the northwest to north while winds over parts of Peninsular Malaysia and the northern parts of Borneo are expected to blow from the northeast.
- 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.
