Latest Weather and Haze Situation
Dry conditions were observed over many parts of the Mekong sub-region today with the exception of a few showers over the northern and central parts of Myanmar. Widespread hotspots were detected in the northern and central parts of Lao PDR while clusters of scattered hotspots were detected in the southern parts of Viet Nam and the central parts of Myanmar. Isolated hotspots were detected elsewhere in the northern ASEAN region. Moderate to dense smoke plumes from the central parts of Thailand were observed to drift in the northeast direction towards the northern parts of Lao PDR. Moderate to dense smoke plumes from the northern and central parts of Lao PDR were observed to drift eastwards to the northern and central parts of Viet Nam respectively. Moderate smoke plumes from the northeastern parts of Cambodia were observed to drift eastwards into the central parts of Viet Nam. Meanwhile, moderate smoke plumes from the southern parts of Viet Nam were observed to drift north into the southern parts of Cambodia. Moderate smoke haze was observed over the central and southern parts of Myanmar, with the latter drifting eastwards into the central parts of Thailand.
Scattered showers were observed in the southern ASEAN region today. A few hotspots were detected in Borneo, Peninsular Malaysia and Sumatra. A localised smoke plume was observed in the northwestern parts of Kalimantan.
Weather and Haze Outlook
Over the next few days, dry conditions are forecast to prevail over many parts of the northern ASEAN region except for parts of Myanmar and the southern parts of the Philippines where some showers are forecast. The heightened hotspot and haze situation over the Mekong sub-region could persist leading to continued risks of severe transboundary haze occurrences. The prevailing winds over the Mekong sub- region are forecast to blow from the south to southwest while the prevailing winds over the Philippines are forecast to blow mainly from the northeast or east.
Scattered showers are expected over most parts of the southern ASEAN region except for relatively drier conditions over the northeastern parts of Peninsular Malaysia and over parts of Sabah and Sarawak. Isolated hotspots and localised smoke plumes can emerge in areas facing drier conditions. The prevailing winds over the southern ASEAN region 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.
