Latest Weather and Haze Situation
Dry conditions prevailed over most parts of the ASEAN region today, except over Sumatra and the Lesser Sunda Islands where showers were observed. Scattered hotspots were detected in Myanmar, while few to isolated hotspots were detected elsewhere in the Mekong sub-region, Kalimantan, Peninsular Malaysia and Sumatra. Moderate smoke plumes were observed to emanate from clusters of hotspots in the central parts of Myanmar, while slight localised smoke plumes were also seen to emanate from a few hotspots in the northern and southern parts of Lao PDR. Slight smoke haze was also observed over the eastern parts of Thailand and the northern parts of Cambodia. Due to cloud extensive cloud cover, the full extent of the hotspot and smoke haze situation over eastern parts of Thailand and Cambodia cannot be determined.
Weather and Haze Outlook
Over the next few days, dry weather are expected to persist over the Mekong sub-region and Borneo, while showers are forecast over other parts of the ASEAN region. Isolated hotspots and localised smoke plumes may continue to occur in fire-prone areas experiencing pro-longed periods of dry weather. The prevailing winds over the northern ASEAN region are forecast to blow mainly from the northeast, while prevailing winds over the southern ASEAN region are expected 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.
