Latest Weather and Haze Situation

Showers were observed over most parts of the ASEAN region today, except over southern Sumatra, Java and the Lesser Sunda Islands, where conditions were drier. In the northern ASEAN region, few hotspots were detected in Thailand, while in the southern ASEAN region, few to isolated hotspots were detected in southern Sumatra and Kalimantan. No significant smoke plumes were observed from the satellite imagery.

Weather and Haze Outlook

Wet weather is forecast to persist for most of the ASEAN region over the next few days, except for Peninsula Malaysia, Sumatra, Java, and the Lesser Sunda Islands, where drier conditions are expected. Isolated hotspots with localised smoke plumes may develop in parts of the region which remain dry. The prevailing winds are forecast to blow from the south to southwest for areas north of the Equator and from the east to southeast for areas south of the Equator.

  • 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.
