Latest Weather and Haze Situation

Dry conditions were observed over most of the southern ASEAN region today while cloudy and rainy conditions were observed over the northern ASEAN region under the influence of Tropical Storm Chaba, located over the northern South China Sea. While the hotspot situation over the northern ASEAN region was subdued, isolated hotspots were detected in Sumatra, and a few hotspots were detected in Sarawak. Isolated smoke plumes were also observed to emanate from some hotspots detected in central Sumatra.

Weather and Haze Outlook

Dry weather is expected to continue over Peninsular Malaysia, Singapore and Sumatra in the coming days as well as parts of northern Borneo. Showers are forecast elsewhere in ASEAN region and Tropical Storm Chaba is forecast to track northwest, making landfall north of the ASEAN region in the next few days. Isolated to scattered hotspots and localised smoke plumes may occur, particularly over fire-prone areas in Borneo and Sumatra, if dry weather is prolonged. Under the influence of Tropical Storm Chaba, the winds over the entire ASEAN region are forecast to be strong and blow from the southeast or southwest.

  • 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.
