Latest Weather and Haze Situation
Dry conditions were observed over some parts of central Sumatra, South Kalimantan, Java and the Lesser Sunda Islands, while wet weather prevailed over rest of the southern ASEAN region. Few hotspots were detected in the northern and central parts of Sumatra. The full extent of the hotspot and smoke haze situation could not be determined due to cloud cover.
Over the northern ASEAN region, wet weather prevailed with a few hotspots detected in Viet Nam. No significant smoke plumes were observed from recent satellite imagery.
Weather and Haze Outlook
Over the next few days, showers are expected over most parts of the southern ASEAN region, except over the northern parts of Sumatra where it is forecast to be relatively drier. Isolated hotspots and localised smoke plumes may occur in fire-prone areas experiencing brief periods of dry weather. The prevailing winds south of the Equator are forecast to blow mainly from the southeast to south.
Wet weather conditions are expected to continue over the northern ASEAN region. Hotspot and smoke haze activities are expected to remain subdued. The prevailing winds over north of the Equator are forecast to blow from the southeast to west.
- 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.
