Latest Weather and Haze Situation
Dry weather continued to prevail over the Mekong sub-region, where hazy conditions persisted over several areas. Dense haze continued to be observed over eastern Myanmar, parts of Thailand, and northern parts of Lao PDR and Viet Nam. In northern and northeastern Thailand, air quality remained in the Unhealthy to Very Unhealthy range. There have also been occurrences of transboundary haze over Myanmar, Thailand, Lao PDR and Viet Nam. The full extent of smoke haze in Cambodia and southern Lao PDR could not be determined due to cloud cover. In the southern ASEAN region, there were scattered showers.
Weather and Haze Outlook
The weather is expected to remain dry over the Mekong sub-region but some showers are expected in the eastern half of the sub-region. The prevailing winds are forecast to continue blowing from the southeast or southwest. In the southern ASEAN region, scattered showers with light and variable winds are expected.
- 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.
