Latest Weather and Haze Situation
The Mekong sub-region continued to experience dry and cloudy conditions today while wet weather prevailed over much of the southern ASEAN region. Clusters of scattered hotspots were detected in Cambodia whereas few to isolated hotspots were detected elsewhere in the Mekong sub-region and also in West Kalimantan. Moderate smoke plumes were observed to emanate from clusters of hotspots in the northern and eastern parts of Cambodia, the eastern parts of Thailand as well as the central parts of Myanmar while slight localised smoke plumes were also seen emitting from hotspots detected in the northern parts of Lao PDR. Due to cloud cover, the full extent of the hotspot and smoke haze situation in the Mekong sub-region could not be determined.
Weather and Haze Outlook
Over the next few days, dry weather is expected to persist over most parts of the Mekong sub-region as well as over the western parts of Borneo while showers are forecast over rest of the ASEAN region. The hotspot and haze situation may continue to be elevated over the fire-prone areas in the Mekong sub-region experiencing prolonged dry weather. The prevailing winds north of the Equator are expected to blow from the northeast to east, while the prevailing winds south of the Equator are forecast to blow from the west or northwest.
- 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.
- The 2500 ft winds (depicted by arrows) are model analysis winds.
