Latest Weather and Haze Situation

Tropical Storm Saudel continues to track westwards towards northern Viet Nam. Meanwhile, Tropical Storm Molave to the east of Philippines brought widespread shower activities over the archipelago. Rainy conditions were also observed over most parts of the ASEAN region. Isolated hotspots were detected over the Mekong Sub-region and the Lesser Sunda Islands, though no smoke haze was observed.

Weather and Haze Outlook

For the next few days, rainy conditions are forecast to continue over most parts of the ASEAN region. Tropical Storm Saudel is expected to weaken and dissipate over the northern ASEAN region. Meanwhile, Tropical Storm Molave is forecast to continue tracking westwards over the northern South China Sea and enhance shower activities over the Philippines. The prevailing winds are forecast to remain variable over the northern ASEAN region and to blow mainly from the southeast or southwest over the southern ASEAN region.

  • 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.
  • The regional haze situation is updated thrice daily at 0200 UTC, 0500 UTC and 0900 UTC upon activation of Alert Level 2. Updates at 0200 and 0500 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.
