Latest Weather and Haze Situation
Wet weather and cloudy conditions were observed over most of the ASEAN region today, apart from the Lesser Sunda Islands and Java where it was drier. Few hotspots were detected in Kalimantan, Viet Nam and Thailand, but no significant smoke plumes were observed from satellite imagery due to extensive cloud cover.
Weather and Haze Outlook
In the coming days, wet weather is expected over most of the ASEAN region, except over parts of Java, Thailand and Viet Nam where it is forecast to be drier. Isolated hotspots and localised smoke plumes may still occur over areas experiencing prolonged dry conditions. The prevailing winds over the northern ASEAN region are likely to blow mainly from the southwest, except over the Philippines where the winds are expected to blow from the northwest to north. The prevailing winds over the southern ASEAN region are forecast to blow from the southeast to southwest.
- 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.
