Latest Weather and Haze Situation
Dry conditions were observed over many parts of the Mekong sub-region today with the exception of showers observed over the southern parts of Thailand and the Philippines. Scattered hotspots were detected in parts of Cambodia, the central parts of Myanmar and the southern parts of Lao PDR. Isolated hotspots were detected elsewhere in the Mekong sub-region. Moderate to dense smoke haze was observed in the northern, eastern and central parts of Myanmar. Moderate smoke haze was also observed to drift southeastwards from the eastern parts of Myanmar into the northern parts of Thailand. Slight to moderate smoke plumes were observed to emanate from hotspots in the southern parts of Lao PDR and the northern parts of Cambodia. Localised smoke plumes were observed elsewhere in the Mekong sub-region. A few air quality stations in the northern parts of the sub- region are reporting Very Unhealthy levels with many stations reporting Unhealthy levels. The hotspot and haze situation could not be fully determined due to extensive cloud cover over the northern and eastern parts of the Mekong sub- region.
In the southern ASEAN region, widespread showers were observed. The hotspot and haze situation remains subdued over the region.
Weather and Haze Outlook
In the coming days, dry conditions are forecast to prevail over the Mekong sub-region except for wet weather expected over the eastern parts of the Mekong sub-region as well as the Philippines. The hotspot and haze situation can intensify in areas of the Mekong sub-region facing prolonged drier conditions, with a continued risk of transboundary haze occurrence. The prevailing winds over the northern ASEAN region are forecast to remain strong and blow mainly from the northeast.
For the southern ASEAN region, showers are forecast to continue. The hotspot and haze situation is likely to remain subdued. The prevailing winds over the southern ASEAN region are forecast to blow from the west to northwest except for winds over Peninsular Malaysia and Singapore to blow mainly 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.
