Catastrophic floods and landslides across Southeast Asia – set off by overlapping storm systems, including Cyclone Senyar and Cyclone Ditwah – have pushed the regional death toll past 1,600, with hundreds still missing as rescue crews struggle to reach isolated communities.
Indonesia has reported the most severe losses. In Aceh and in North and West Sumatra, officials have confirmed more than 830 deaths, while more than 500 people remain missing. Thousands have been injured or displaced, and entire villages have been swept away. Authorities estimate that more than half a million residents have been forced from their homes.
Sri Lanka has also suffered major destruction from Cyclone Ditwah. At least 618 people have been confirmed dead, and the toll may rise as crews attempt to access remote, flood-stricken regions where landslide risks remain high. Heavy rainfall continues to complicate rescue efforts.
In Thailand, southern provinces saw widespread flooding and storm damage. At least 185 fatalities have been reported, though local officials warn the real number could be higher. Those additional figures have not been independently verified.
Across the region, millions have been affected by destroyed homes, collapsed roads and bridges, power outages, and disruptions to food, water, and medical services. Relief teams face significant obstacles, including damaged infrastructure and limited access to mountainous or rural areas. Public health concerns are growing as stagnant water increases the risk of disease.
Climate experts say climate change likely intensified rainfall and flooding, while environmental degradation – including deforestation – may have reduced natural protections against water runoff and landslides. However, publicly confirmed data linking specific deforestation levels to this disaster is not yet available.
