SINGAPORE: Raging wildfires in Indonesia have shrouded much of Southeast Asia in hazardous haze, prompting the Association of Southeast Asian Nations’ climate monitoring body to escalate to its most severe warning level.
“Activation of Alert Level 3 for the Southern ASEAN region,” announced the ASEAN Specialized Meteorological Center (ASMC) on its official platform on Saturday.
The ASMC, located near Singapore’s Changi Airport, operates a four-tiered alert system ranging from Level 0 to Level 3. The highest tier is activated when there is a “high risk of severe transboundary haze,” characterized by sustained hotspot activity, persistent smoke coverage, prolonged dry conditions, and wind patterns directing haze toward neighboring countries.
This current alert follows two previous activations this year, occurring on August 26 and March 27. The extended haze conditions have severely impacted daily life across the region, forcing school closures and resulting in a marked increase in respiratory health issues.
In a related development, Singapore authorities announced on Friday that they have identified seven Indonesian companies potentially linked to the fires and will be issuing formal warnings. Officials cautioned that the situation may deteriorate further before showing signs of improvement.
