Latest Weather and Haze Situation
Cloudy conditions with isolated showers were observed over most parts of the northern ASEAN region, except for the southern and central parts of the Philippines and the northwestern and eastern parts of the Mekong sub-region where partly cloudy conditions were observed. From the overnight satellite surveillance, isolated hotspots were mostly detected in Thailand, Myanmar and Viet Nam. Based on recent satellite imageries, slight smoke haze was observed over parts of Myanmar. The full extent of the hotspot and smoke haze situation over the Mekong sub-region could not be determined due to extensive cloud cover. The air quality over the Mekong sub-region has improved further recently, with most stations measuring Good to Moderate levels.
Scattered showers were observed over Sumatra, Borneo and the northern parts of Peninsular Malaysia. It was partly cloudy elsewhere in the southern ASEAN region. The hotspot activity in the region remained low, with a few hotspots mostly detected in Borneo. No significant smoke plumes were observed.
Weather and Haze Outlook
In the coming days, while drier conditions are forecast over the northwestern and eastern parts of the Mekong sub-region, wet weather is expected over the rest of the northern ASEAN region. The overall wet weather conditions can help to suppress the hotspot and smoke haze situation over most of the Mekong sub-region. However, over the drier areas in the northwestern and eastern parts of the sub-region, the situation may remain elevated. While the prevailing winds over the Philippines are forecast to blow from the east, the prevailing winds over the Mekong sub-region are forecast to be light and variable in direction.
Showers are expected over most parts of the southern ASEAN region except for the Lesser Sunda Islands and the eastern parts of Java where conditions are drier. While the overall hotspot activity is expected to remain low under the prevailing weather conditions, isolated hotspots with localised smoke plumes can still occur over drier areas. The prevailing winds over areas near the Equator are expected to be light and variable in direction, but the prevailing winds over areas south of the Equator are forecast to blow from the east or southeast.
- 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.
