Latest Weather and Haze Situation

Wet weather conditions prevailed over most parts of the ASEAN region today except for Java and the Lesser Sunda Islands. Widespread showers fell over the Mekong sub-region due to the influence of a low pressure system. Isolated hotspots were detected in Sumatra and Kalimantan. No significant smoke haze was observed.

Weather and Haze Outlook

Over the next few days, wet weather is expected to prevail over most parts of the ASEAN region. The low pressure system over the Mekong sub-region is forecast track northwestward and continue to bring extensive rainfall over the area. The overall hotspot activity is likely to remain subdued. However, hotspots with localised smoke plumes can still be expected over areas that experience drier conditions. The prevailing winds are forecast to be generally light and variable in direction over the northern ASEAN region. In the southern ASEAN region, the prevailing winds are forecast to blow mainly from the northeast or 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.
