Latest Weather and Haze Situation
Dry and cloudy conditions were observed over the northern ASEAN region overnight, apart from the central parts of the Mekong sub-region and the northern parts of the Philippines where there were isolated showers. Few to isolated hotspots were detected in the Mekong sub-region. Slight to moderate smoke haze was observed over many parts of Myanmar. The full extent of the hotspot and haze situation over the Mekong sub-region could not be determined due to cloud cover.
Showers prevailed over the southern ASEAN region overnight, except over the northern parts of Peninsular Malaysia and the northern parts of Borneo where it was relatively drier. The hotspot activity remained low and no significant smoke plumes were observed from satellite imagery.
Weather and Haze Outlook
Over the next few days, dry weather is likely to persist over the northwestern parts of the Mekong sub-region while showers are forecast elsewhere in the northern ASEAN region. The showers are expected to improve the hotspot and smoke haze situation over the Mekong sub-region, with a lowered risk of transboundary haze occurrence. The prevailing winds over the northern ASEAN region are likely to be light and variable in direction, except over the Philippines where the winds are forecast to blow from the southeast.
Wet weather is expected to continue over the southern ASEAN region, which should keep the hotspot and smoke haze situation subdued. The prevailing winds over the southern ASEAN region are likely 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.
