Latest Weather and Haze Situation

Shower activities and cloudy conditions prevailed over much of the ASEAN region today. Relatively drier weather was observed over southern Sumatra and Kalimantan, where isolated hotspots were detected. However, no significant smoke haze was observed.

Weather and Haze Outlook

In the next few days, rainy weather is forecast over most parts of the ASEAN region. While the showers are expected to help subdue the overall smoke haze situation, some isolated hotspots and smoke plumes can still be expected in areas that experience dry conditions. Under the influence of Tropical Storm Lupit to the northwest of the Philippines, moderate to strong southwesterly winds are forecast over areas north of the equator. For areas south of the equator, the prevailing winds are forecast to blow mainly from the 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 thrice daily at 0200 UTC, 0500 UTC and 0900 UTC upon activation of Alert Level 2 or Alert Level 3. Updates at 0200 and 0500 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.
