Regional Haze Situation








Latest Weather and Haze Situation
Showers prevailed over most of the ASEAN region today, apart from parts of Sumatra and the Lesser Sunda Islands where it was relatively drier. Few hotspots were detected in Sumatra, Thailand and Myanmar, but no significant smoke plumes were observed from satellite imagery. The full extent of the hotspot and smoke haze situation over the ASEAN region could not be determined due to cloud cover.
Weather and Haze Outlook
Over the next few days, wet weather is likely to continue over the ASEAN region, except over the Lesser Sunda Islands where drier conditions are expected. Isolated hotspots and smoke plumes may still develop over drier areas in the region. The prevailing winds over areas south of the Equator are forecast to blow mainly from the east to southeast. The prevailing winds over areas north of the Equator are likely to blow from the southwest to west, except over the Mekong sub-region and the equatorial region where light and variable winds are expected.
- 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.
- The 2500 ft winds (depicted by arrows) are model analysis winds.
