Latest Weather and Haze Situation
Wet weather was observed over many parts of the northern ASEAN region today, although drier conditions were observed over the Philippines. Isolated hotspots were detected mainly in the northern parts of Lao PDR while a few hotspots were detected elsewhere in the Mekong sub- region. Slight to moderate smoke plumes were observed to emanate from hotspots in the northern parts of Lao PDR and drift eastwards into the northern parts of Viet Nam. Localised smoke plumes were also observed in the western parts of Myanmar. A few air quality stations in the northern parts of the Mekong sub-region are reporting Unhealthy levels. The full extent of the hotspot and haze situation could not be fully determined due to extensive cloud cover over many parts of the Mekong sub-region.
For the southern ASEAN region, scattered showers were observed with the exception of drier conditions observed over parts of Sumatra and Kalimantan. A few hotspots were detected in Sumatra and Sarawak. A localised smoke plume was observed to emanate from a hotspot in Sarawak.
Weather and Haze Outlook
In the coming days, increased rainfall is expected over many parts of the northern ASEAN region. The hotspot and haze situation is expected to improve in most parts of the sub-region experiencing wet weather, with a reduced risk of transboundary haze. The prevailing winds over the Mekong sub-region are forecast to blow from the south to west, except for the northeastern parts where winds are forecast to blow from the northeast. The prevailing winds over the Philippines are forecast to blow from the southeast.
For the southern ASEAN region, showers are forecast to continue. The hotspot and smoke haze situation is expected to remain subdued over the region. The prevailing winds over the southern ASEAN region are forecast to be light and variable in direction.
- 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.
