Latest Weather and Haze Situation
Scattered showers and cloudy conditions were observed over most parts of the ASEAN region today, except over the southern parts of Sumatra, the southern and eastern parts of Kalimantan, as well as Java and the Lesser Sunda Islands, where relatively drier conditions prevailed. Scattered hotspots were detected in Kalimantan while few to isolated hotspots were detected in Sumatra, Thailand, Viet Nam and Java. Smoke plumes were observed in central Kalimantan. The full extent of the hotspot and haze situation could not be determined due to extensive cloud cover.
Weather and Haze Outlook
In the coming days, wet weather conditions are forecast to continue over most of the ASEAN region, aside from over southern Sumatra, southern parts of Borneo, Java, and the Lesser Sunda Islands, where drier conditions are expected. While the overall hotspot and smoke haze situation is likely to remain subdued, localized smoke plumes may develop in regions experiencing prolonged periods of dry weather. The prevailing winds over the northern ASEAN region are forecast to blow from the south to west-southwest under the influence of Tropical Storm Noul, while the prevailing winds over the southern ASEAN region are expected to blow primarily from the east-southeast to the south-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.
