Latest Weather and Haze Situation
Dry conditions were observed over parts of the southern ASEAN region today, except over parts of Borneo, Peninsular Malaysia and central Sumatra where there were some showers. Few hotspots were detected Kalimantan and Sumatra. Moderate smoke haze was observed over the southern parts of Papua and the central parts of Sulawesi. The full extent of the hotspot and smoke haze situation over the southern ASEAN region could not be determined due to extensive cloud cover. Showers were observed over parts of the northern ASEAN region, except for relatively drier conditions over the northern and central parts of the Mekong sub-region. Hotspot activity remained low.
Weather and Haze Outlook
Over the next few days, parts of the southern ASEAN region are forecast to remain dry, except over Peninsular Malaysia, Sumatra, as well as parts of Java and Borneo where there are likely to be showers. The hotspot and smoke haze situation may improve over areas with showers, with a reduced risk of transboundary haze occurrence. However, hotspot with smoke plumes can still occur over areas experiencing prolonged dry weather. The prevailing winds over the southern ASEAN region are expected to blow mainly from the east to southeast. Showers are forecast over the northern ASEAN region, except for relatively drier conditions over parts of northern and eastern Mekong sub-region. Isolated hotspots and smoke plumes may develop over areas experiencing prolonged dry conditions. The prevailing winds over the northern ASEAN region are likely to blow from the northeast to east, apart from the northern and western parts of Mekong sub-region where the winds are expected to be light and variable in direction.
- 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.
