At least 442 people have been confirmed dead, while more than 400 remain missing. Authorities warn that the toll is likely to rise as rescuers reach isolated communities.

The flooding began nearly a week ago when Cyclone Senyar swept across the Malacca Strait, unleashing heavy rains that inundated villages, destroyed homes and swept away infrastructure.

Entire neighbourhoods in Aceh, North Sumatra and West Sumatra were submerged, with thousands of buildings damaged or flattened.

Officials estimate that over 290,000 residents have been displaced, many forced to take shelter in temporary camps.

Rescue operations have been complicated by washed-out roads, collapsed bridges and downed communication lines. In some districts, aid has yet to arrive, leaving survivors desperate for food, clean water and medicine.

Reports from North Sumatra indicate that some residents have resorted to breaking into convenience stores to secure basic supplies. Social media footage shows people wading through waist-deep waters to salvage what they can.

International assistance is beginning to flow in. Relief agencies are coordinating with Indonesian authorities to deliver emergency supplies by air and sea.

Technology companies such as Starlink have stepped in, offering free satellite connectivity to restore communication in the hardest-hit areas. Despite these efforts, officials caution that the scale of devastation means recovery will take months, if not longer.

The floods in Indonesia are part of a broader regional crisis. Torrential rains linked to the same cyclone system have battered Thailand, Malaysia, the Philippines, and Sri Lanka, leaving more than 900 people dead across South Asia this month.

Climate experts note that such rare tropical storms in the Malacca Strait may become more frequent as global warming intensifies weather extremes.
