- Alert Level 1 | Start of Dry Season for the Southern ASEAN Region
- The activation of Alert Level 1 indicates the start of dry season for the southern ASEAN region. The regional haze situation will be updated daily at 0900 UTC.
Regional Haze Situation
Latest Weather and Haze Situation
Rainy weather prevailed over most parts of the ASEAN region today, except over Java, the Lesser Sunda Islands, and Sulawesi where the weather was relatively drier. Overall in the region, hotspot activity remained subdued under widespread shower activities. Few hotspots were detected in Thailand, Viet Nam, Kalimantan, Sarawak, and Sumatra, but no smoke plumes were observed.
Weather and Haze Outlook
Showers are forecast for many parts of the ASEAN region in the coming days. However, brief periods of drier conditions are forecast for some parts of central and southern Sumatra, as well as southern Borneo. Isolated hotspots, occasionally with localised smoke plumes, may develop if dry weather persists over the fire-prone areas there. The prevailing winds are forecast to blow mainly from the southwest over areas north of the Equator, except the Philippines where variable winds are forecast due to the influence of Tropical Storm Guchol over the Philippine Sea. For areas south of the Equator, southeasterly winds are forecast.
- 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.
