Latest Weather and Haze Situation
Scattered showers were observed over the southern ASEAN region today while drier conditions were observed over the Mekong sub-region. Complete hotspot observation is not available today over Mekong sub-region, Peninsular Malaysia, Sumatra and Java due to technical maintenance at the source data provider. Slight localised smoke haze was observed in the northern and central parts of Myanmar, the southern parts of Viet Nam, and the central parts of Sumatra. Localised smoke plumes were also observed in the northern parts of Lao PDR as well as the northern and central parts of Thailand.
Weather and Haze Outlook
In the coming days, wet weather is expected to prevail over the ASEAN region with the exception of drier conditions over the Mekong sub-region and the northern parts of Peninsular Malaysia. Heavier showers are also expected over parts of Viet Nam under the influence of Typhoon Koto. Isolated hotspots and localised smoke plumes can emerge in areas facing prolonged drier conditions. The prevailing winds over the northern ASEAN region are expected to blow from the northeast. The prevailing winds over the southern ASEAN region are forecast 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.
- The 2500 ft winds (depicted by arrows) are model analysis winds.
