Latest Weather and Haze Situation
Dry conditions were observed over many parts of the southern ASEAN region today except for showers observed over parts of Peninsular Malaysia and the northern parts of Sumatra. Clusters of scattered hotspots were detected in West Kalimantan while a few to isolated hotspots were detected elsewhere in Borneo. Isolated hotspots were detected mainly in the southern parts of Sumatra and a few hotspots were detected in Java and Sulawesi. Moderate to dense smoke plumes were observed in many parts of Kalimantan, and were observed to drift northwards from West Kalimantan into the western parts of Sarawak. Slight to moderate smoke plumes were also observed in the southern parts of Sumatra and the eastern parts of Java.
Wet weather was observed over the northern ASEAN region and the hotspot situation remained subdued today. No significant smoke plumes were observed.
Weather and Haze Outlook
Dry weather is forecast to continue over most parts of the southern ASEAN region in the coming days except for the northern parts of Peninsular Malaysia and Sumatra where some showers may occur. The hotspot and smoke haze situation may remain escalated in areas facing prolonged dry conditions, with increased chances of transboundary haze occurrences. The prevailing winds over the southern ASEAN region are forecast to blow from the southeast or south.
Meanwhile, over the northern ASEAN region, widespread wet weather is expected except for relatively drier conditions over the central parts of Viet Nam. The hotspot and haze situation is expected to remain suppressed in the coming days. The prevailing winds over the northern ASEAN region is expected to blow from the 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 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.
