Latest Weather and Haze Situation
Dry conditions were observed over the Mekong sub-region this morning. Widespread hotspots were detected in the northern and western parts of Thailand, in the northwestern parts of Lao PDR and in many parts of Myanmar. Clusters of scattered hotspots were detected elsewhere in the Mekong sub-region. Moderate to dense smoke haze was observed in many parts of Myanmar and also in the northern parts of Thailand and Lao PDR.
A few showers were observed over the southern ASEAN region this morning. A few hotspots were detected in Peninsular Malaysia, Borneo and the central parts of Sumatra, though no significant smoke plumes could be observed from recent satellite imagery.
Weather and Haze Outlook
In the coming days, dry conditions are forecast to prevail over the northern ASEAN region except for some showers forecast over the northern parts of Myanmar and Viet Nam. Prolonged dry conditions over areas of the Mekong sub-region can lead to persistent and extensive hotspot and smoke haze activities, with an elevated risk of transboundary haze occurrence. The prevailing winds over the Mekong sub-region are forecast to blow from the southwest to west while winds over the Philippines are forecast to blow mainly from the east.
In the coming days, scattered are forecast over most parts of the southern ASEAN region, except for relatively drier conditions forecast over the western parts of Borneo and the northern parts of Peninsular Malaysia. Hotspots and localised smoke plumes can occur in areas experiencing drier conditions. The prevailing winds over the southern ASEAN region 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.
