Latest Weather and Haze Situation
Wet weather and cloudy conditions were observed over most parts of the ASEAN region today, except for the western parts of the Mekong sub-region where it was fair weather conditions. Based on the latest satellite surveillance, isolated hotspots are mostly detected in the central parts of Myanmar but no significant smoke plumes were observed.
Weather and Haze Outlook
In the coming days, widespread showers are forecast over most parts of the southern ASEAN region and the Philippines. In the Mekong sub-region, showers are expected over the northern and eastern parts of the sub-region while drier conditions are forecast in the rest of the sub-region. Hotspot activity is generally suppressed under the overall wet conditions in the ASEAN region but isolated hotspot with localised smoke plumes could develop in the fire-prone areas of the Mekong sub-region experiencing drier conditions. The prevailing winds over the northern ASEAN region are forecast to blow mostly from the northeast or east, while the prevailing winds over the southern ASEAN region are expected to blow from the northwest or southwest.
- 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.
