Latest Weather and Haze Situation
Dry conditions persisted over most of the southern ASEAN region overnight, apart from the northern parts of Sumatra, Peninsular Malaysia and Borneo where there were some showers. Widespread hotspots were detected over Kalimantan and Sumatra while few hotspots were detected in Sarawak. Moderate to dense smoke haze was observed over parts of Kalimantan, the southern parts of Sumatra and the western parts of Sarawak. Air quality stations in Kalimantan, the western parts of Sarawak and the southern parts of Sumatra reported Unhealthy to Hazardous levels. The overall hotspot and smoke haze situation over the southern ASEAN region could not be fully determined due to cloud cover. Over the northern ASEAN region, showers were observed and the hotspot and smoke haze situation remained subdued.
Weather and Haze Outlook
In the coming days, the southern ASEAN region is expected to remain dry, except for showers forecast over parts of Peninsular Malaysia, the northern and central parts of Sumatra and the northern parts of Borneo. While the showers may bring some relief to the hotspot and smoke haze situation, there is still a risk of transboundary haze occurrence especially over areas experiencing prolonged dry conditions. The prevailing winds over the southern ASEAN region are likely to blow from the southeast to south. Wet weather is expected over the northern ASEAN region, which should keep the hotspot activity low. The prevailing winds over the northern ASEAN region are forecast to turn generally light and variable in direction, apart from the Philippines where the winds are likely to blow from the 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.
