Latest Weather and Haze Situation
Dry conditions were observed over most parts of the southern ASEAN region today except for showers over the northern parts of Borneo and Sumatra as well over parts of Peninsular Malaysia. Clusters of scattered hotspots were detected in parts of Kalimantan and the southern parts of Sumatra. A few to isolated hotspots were detected in Java, Sulawesi, Sarawak, Sabah as well as the southern parts of Sumatra. Moderate to dense transboundary smoke haze was also observed to cover southern and central Sumatra, Kalimantan, Sarawak, Peninsular Malaysia, Singapore as well as the southern parts of Viet Nam. Moderate smoke plumes were observed in Sulawesi. Air quality stations in areas affected by transboundary haze are also reporting Moderate to Unhealthy levels. Some air quality stations in Kalimantan and Sumatra are reporting Unhealthy to hazardous levels. Meanwhile, wet weather was observed over most parts of the northern ASEAN region. The hotspot count remained low and there was no significant smoke haze observed apart from Viet Nam.
Weather and Haze Outlook
In the coming days, dry conditions are forecast to persist over many parts of the southern ASEAN region, except for the northern parts of Sumatra, Peninsular Malaysia and Borneo where some showers are forecast. The hotspot and haze situation in the region is expected to remain escalated with a continued risk of transboundary smoke haze. The prevailing winds over the southern ASEAN region are forecast to blow mainly from the east-southeast or southeast except for parts of Borneo where winds are forecast to be light and variable in direction. Over the northern ASEAN region, wet weather as well as subdued hotspot and smoke haze activities are forecast to continue in the coming days. The prevailing winds over the Mekong sub-region are forecast to be light and variable in direction while the prevailing winds over the Philippines are forecast to blow from the northwest or 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.
