Latest Weather and Haze Situation
It was dry over the northern and central parts of Sumatra and the southern parts of Peninsular Malaysia today, while showers were observed elsewhere in the ASEAN region. Isolated hotspots were detected in Sumatra, whereas few hotspots were detected in Kalimantan and Viet Nam. A slight localised smoke plume was observed emanating from a hotspot detected in the central parts of Sumatra.
Weather and Haze Outlook
In the coming days, drier conditions are expected over the Peninsular Malaysia, the northern and central parts of Sumatra, Java and the Lesser Sunda Islands, while wet weather is forecast over the rest of the ASEAN region. Under prolonged dry conditions, isolated hotspots and localised smoke plumes may increase especially over fire-prone areas. The prevailing winds over north of the Equator are likely to blow from the south to west, whereas the prevailing winds south of the Equator are expected 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.
