Latest Weather and Haze Situation

Showers and cloudy conditions prevailed over most parts of the ASEAN region today whereas relatively drier conditions were observed over the western parts of Borneo. Few to isolated hotspots were detected in Kalimantan, Sarawak, Sumatra, Thailand, Cambodia and Viet Nam. Slight localised smoke plume was observed to emanate from a hotspot in southern Sumatra from satellite imagery.

Weather and Haze Outlook

Over the next few days, wet weather is expected to over most parts of the ASEAN region while drier conditions are forecast over some parts of northern Sumatra. Hotspots and isolated smoke plumes may occur more frequently in fire-prone areas experiencing pro-longed dry conditions. The prevailing winds north of the Equator are forecast mostly to blow from the southwest to west whereas the winds south of the Equator are expected to blow from the eats to 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 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.
