By January 4, 2026, Indonesian authorities reported at least 1,177 deaths and 165 missing, with more than 3.3 million residents affected and around 1.1 million displaced across 52 cities and regencies. Economic losses exceeded 68.7 trillion rupiah ($4.13 billion), with 166,743 houses damaged along with hundreds of bridges, health facilities and schools. The same storm systems killed roughly 200 more people in southern Thailand and Malaysia, turning a regional weather anomaly into Southeast Asia's deadliest climate disaster of the year.
