- Alert Level 2 | Activation of Alert Level 2 for the Mekong sub-region
- With the activation of Alert Level 2 for the Mekong sub-region, the regional haze situation is updated three times a day at 0200 UTC, 0500 UTC and 0900 UTC from 7 Jan 2020.
Regional Haze Situation
Latest Weather and Haze Situation
Dry weather persisted in the Mekong sub-region today. Scattered hotspots were detected in many parts of the sub-region. In particular, hazy conditions persisted in northern Thailand, where Unhealthy air quality was reported by some stations. Smoke haze from hotspots was also observed in parts of Myanmar and Cambodia. Localised smoke haze was detected in parts of Lao PDR, and southern Viet Nam. A monsoon surge had brought moderate to strong north-easterly winds over the South China Sea. In the southern ASEAN region, there were scattered showers.
Weather and Haze Outlook
Over the next few days, dry weather can be expected to persist in the Mekong sub-region. Under the prolonged dry weather, hotspot activities and hazy conditions in the sub-region may continue. In the southern ASEAN region, scattered showers are forecast. The prevailing winds in the ASEAN region are forecast to blow from the north-east or east over areas north of the equator, but shift to blow from the north-west or west over areas south of the equator.
- 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.
