Latest Weather and Haze Situation

Scattered showers fell over many parts of the Mekong sub-region today and cloudy conditions were observed over Myanmar and the northern parts of Thailand, Lao PDR and Viet Nam. While some isolated hotspots were detected in parts of the sub-region, no significant smoke haze was observed due to heavy cloud cover and shower activities since this morning. Elsewhere in the northern ASEAN region, Typhoon Surigae continued to gain strength and tracked west-northwest towards the Philippines.

In the southern ASEAN region, wet weather prevailed as shower activities were observed over many areas in the region. On the whole, the hotspot activities and smoke haze situation remained subdued.

Weather and Haze Outlook

Shower activities are forecast for many parts of the Mekong sub-region over the next one to two days, and the showers may help subdue the overall hotspot and smoke haze situation in the sub-region. However, drier conditions are forecast to return thereafter. The prevailing winds are forecast to blow mainly from the southeast or southwest. To the east of the Philippines, Typhoon Surigae is forecast to continue strengthening and track west-northwestward.

In the southern ASEAN region, wet weather conditions can be expected to prevail in coming days. Hotspot activities and smoke haze situation are likely to remain generally subdued. The prevailing winds are forecast to blow from the southeast or 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.
  • 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.
