Latest Weather and Haze Situation
Wet weather and cloudy conditions persisted over most areas of the ASEAN region today with relatively drier conditions over the central parts of the Mekong sub- region. Isolated hotspots with slight smoke plumes were observed in parts of Cambodia. Few hotspots were also detected in other parts of the Mekong sub- region and eastern Kalimantan.
Weather and Haze Outlook
In the coming days, showers are expected to develop over most areas of the ASEAN region, while the central Mekong sub-region including eastern parts of Thailand, Lao PDR and Cambodia are forecast to face relatively drier conditions. The overall hotspot situation in the ASEAN region is likely to remain subdued, however isolated hotspots with localized smoke plumes may still develop in areas of the sub-region experiencing drier conditions. The prevailing winds over the northern ASEAN region are generally northeast, except over the Mekong sub-region where light and variable winds are expected. The prevailing winds over the southern ASEAN region are likely to be northeast to westerly 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.
