Latest Weather and Haze Situation
Dry and cloudy conditions were observed over Thailand, the central and southern parts of Viet Nam, the southern parts of Sumatra, the western parts of Kalimantan, and the Lesser Sunda Islands, while showers were observed elsewhere in the ASEAN region. Few to isolated hotspots were detected in Viet Nam, Thailand, Cambodia, the southern parts of Sumatra and the western parts of Kalimantan. However, no significant smoke plumes were observed from recent satellite imagery due to cloud cover.
Weather and Haze Outlook
Over the coming days, drier weather is forecast over Peninsular Malaysia, Java, the lesser Sunda Islands, the southern parts of Sumatra, and the western and southern parts of Borneo, while showers can be expected over the rest of the ASEAN region. Isolated hotspots and localised smoke plumes can occur in areas experiencing drier conditions. The prevailing winds over the northern ASEAN region are forecast to blow from the south to west, while the prevailing winds over the southern ASEAN region are forecast to blow from the southeast to south, except over Kalimantan, where winds are mainly 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.
- The 2500 ft winds (depicted by arrows) are model analysis winds.
