Latest Weather and Haze Situation

Rainy and cloudy conditions prevailed over most of the ASEAN region, except over Java, the Lesser Sunda Islands and parts of Lao PDR and Viet Nam where it was relatively drier. Isolated hotspots were detected mainly in Thailand and Sulawesi while few hotspots were detected in Java, Sumatra, East Kalimantan and Viet Nam, but no significant smoke plumes were observed from satellite imagery. Due to extensive cloud cover, the full extent of the hotspot and smoke haze situation in the region could not be determined.

Weather and Haze Outlook

In the coming days, showers are expected over most parts of the ASEAN region except for Java, the Lesser Sunda Islands and South Kalimantan. The overall hotspot and smoke haze situation is likely to remain subdued, though localized hotspots and smoke plume may occur in drier areas. The prevailing winds south of the Equator are forecast to blow mainly from the southeast to south. The prevailing winds over areas north of the Equator are forecast to remain light and variable in direction.

  • 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.
