ASEAN raises alert to highest level as Indonesian fires blanket region with haze
The ASEAN climate and fire monitor has activated Alert Level 3 for the southern ASEAN region due to persistent Indonesian fires and severe transboundary haze.
The Singapore ASEAN Specialised Meteorological Centre announced the activation of Alert Level 3, the highest tier in its four-level system, for the southern ASEAN region. The alert reflects ongoing fires in Indonesia that have generated persistent, moderate-to-dense smoke haze over at least two consecutive days, combined with dry weather and wind patterns that carry the haze toward neighboring nations. This marks the third issuance of a Level 3 alert this year, following similar warnings on March 27 and August 26.
Authorities note that the prolonged haze has disrupted daily life, prompting school closures and a surge in respiratory complaints across large parts of Southeast Asia. Singapore also indicated it would warn seven Indonesian firms identified as responsible for the fires, while cautioning that conditions could worsen. The situation underscores the transboundary nature of the pollution and the challenges of regional fire management.
Why it matters
Severe haze threatens public health and daily activities across multiple Southeast Asian nations.
