INDONESIA STRUCK by FLOODS — 600+ Houses Inundated, Residents Evacuate (Latest Updates)

Northern Sumatra is facing renewed heavy rain warnings after floods affected thousands of residents during Indonesia’s dry season. On October 30, 2026, Aceh and North Sumatra were the only provinces placed under the country’s highest rainfall alert, warning of possible floods, flash floods and landslides. Twenty-one other provinces remained under a lower-level watch as the threat spread across the archipelago. The flooding began in North Sumatra, where Asahan, Langkat and Mandailing Natal reported inundated homes, damaged roads and evacuations. South Aceh also saw rivers overflow into villages, forcing 46 residents to seek shelter. Although some floodwater has receded, officials are preparing for another round of heavy rain. In this video, we examine the latest flooding in Sumatra, repeated thunderstorms across Indonesia, and the wildfire smoke affecting Borneo. We also explain how El Niño, the positive Indian Ocean Dipole, the Madden-Julian Oscillation and Kelvin waves are influencing the region's weather. A weak low-pressure system is also developing in the Andaman Sea, north of Sumatra. Forecasters expect it to strengthen slowly, while heavy rain and strong wind warnings continue into early November. For communities already affected by flooding, the next several days could bring another serious test. Global Weather covers natural disasters and extreme weather events as they develop, using sourced reporting and avoiding unsupported speculation.
