Regional Haze Situation
Latest Weather and Haze Situation
The weather over most of the northern ASEAN region remained dry and isolated hotspots were detected in Cambodia, Lao PDR, Myanmar, Thailand and Viet Nam. In the southern ASEAN region, shower activities helped subdue the overall hotspot activity with a few hotspots detected in parts of Sumatra and Peninsular Malaysia.
Weather and Haze Outlook
In the coming days, dry conditions are forecast to persist over much of the Mekong sub-region and an increase in hotspots with localised smoke haze can be expected over areas that experience prolonged dry weather. Elsewhere, showers are forecast over parts of eastern Viet Nam and the Philippines. The prevailing winds in the northern ASEAN region are forecast to remain strong and blow from the northeast or east. For the southern ASEAN region, wet weather is forecast to continue and the overall hotspot activity is likely to remain subdued. The prevailing winds are forecast to blow mainly from the northwest or 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 thrice daily at 0200 UTC, 0500 UTC and 0900 UTC upon activation of Alert Level 2 or Alert Level 3. Updates at 0200 and 0500 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.
