Latest Weather and Haze Situation

Wet weather was observed over most parts of the ASEAN region except for the Lesser Sunda Islands where it was partly cloudy. Scattered hotspots were detected in Viet Nam while isolated hotspots were detected in Cambodia and central Sumatra. No smoke plume was observed.

Weather and Haze Outlook

Over the next few days, isolated to scattered shower activities are forecast to persist over the region except for the central parts of the Mekong sub-region, northern Sumatra and the Lesser Sunda Islands where drier conditions are forecast. While the overall hotspot and haze situation is expected to remain subdued, some hotspot and smoke haze development may still occur in drier areas. The prevailing winds over the northern ASEAN region are expected to blow mostly from the southwest or west while the prevailing winds over the southern ASEAN region are expected to blow from the southeast or south.


  • 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.
