Latest Weather and Haze Situation
Wet weather conditions were observed over most parts of the ASEAN region today, with Typhoon Fung-Wong bringing heavier rainfall over the Philippines. Drier conditions were observed over parts of the Mekong sub region, central Sumatra and north-eastern parts of Borneo. Few hotspots were detected mainly in Viet Nam and the central parts of Sumatra while isolated hotspots were detected in the central and western parts of Kalimantan. However, no significant smoke plumes were observed from satellite imagery due to cloud cover.
Weather and Haze Outlook
In the coming days, wet weather is expected to prevail over many parts of the ASEAN region, with heavier rainfall persisting over the Philippines due to Typhoon Fung-Wong. Drier conditions are expected over the central and eastern parts of the Mekong sub-region, the central parts of Sumatra and the northeastern parts of Borneo. Hotspots and isolated smoke plumes may still develop over fire-prone regions during periods of dry weather. The prevailing winds in the northern ASEAN region are forecast to be light and variable in direction, except over the Philippines where strong winds are expected under the influence of Typhoon Fung-Wong. Winds in the southern ASEAN region are forecast to blow from the south to 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.
