Latest Weather and Haze Situation
Widespread showers were observed over most parts of the ASEAN region today with the exception of drier conditions over parts of Kalimantan and Java. Isolated hotspots were mainly detected in the southern and western parts of Sumatra but no significant smoke plumes were observed.
Weather and Haze Outlook
In the coming days, wet weather is expected to prevail over most parts of the ASEAN region with the exception of drier conditions forecast over the central parts of Sumatra. The hotspot and haze situation over the ASEAN region is expected to remain subdued, however isolated hotspots and localised smoke plumes may still emerge in areas facing drier conditions. The prevailing winds over north of the Equator is forecast to blow mainly from the southwest. The prevailing winds south of the Equator are forecast to blow east to southeast.
- 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.
