ASEAN Weather Monitor Issues Highest Alert as Toxic Haze Grips Region
SCMP · 2 SOURCES1 day ago2 MIN

Summary
The Singapore ASEAN Specialised Meteorological Centre (ASMC) has activated its highest alert level for the southern ASEAN region as ongoing fires in Indonesia continue to blanket parts of Southeast Asia with toxic haze. The Alert Level 3 warning, issued on Friday, was triggered due to high risk of severe transboundary haze with significant and persistent hotspot activities and widespread moderate to dense smoke haze observed over consecutive days. Singapore authorities said they would issue warnings to seven companies in Indonesia identified as responsible for the fires, as four firefighters were killed battling blazes in East Java's Bromo Tengger Semeru National Park.
Key Points
- ASMC Alert Level 3 (highest tier) activated on Friday for the Southern ASEAN region, marking the third such alert this year after August 26 and March 27
- Singapore will issue warnings to seven companies operating in Indonesia that have been identified as responsible for the fires
- Four firefighters died while battling blazes in Bromo Tengger Semeru National Park in East Java on Thursday; two others suffered serious burns
- Hotspots surged to 615 across six priority provinces, according to the forestry department
- Haze has disrupted life across Southeast Asia, closing schools and causing a spike in respiratory complaints among residents
Why It Matters
The activation of the highest alert level underscores the severity of the transboundary haze crisis, which extends beyond national borders to affect millions across the ASEAN region. The deaths of four firefighters highlight the grave risks involved in firefighting operations, while the widespread school closures and health impacts on populations demonstrate the immediate human cost of this environmental disaster. Singapore's decision to warn companies with Indonesian operations signals potential legal and commercial consequences for entities linked to deforestation and land-clearing fires.
