Flash Floods from Nepal’s Rasuwa District Surge into Bihar, Raising Cross‑Border Alarm

Heavy rain triggered flash floods in Nepal’s Rasuwa district, sending a surge of water down the Trishuli and other tributaries that feed into the Indian side of the border. The floodwaters entered Bihar’s river systems within hours, raising water levels in downstream districts that are already vulnerable to monsoon flooding. Local authorities in both countries have begun sharing real‑time data to track the flow and issue timely warnings to communities along the border. The incident highlights the trans‑boundary nature of river basins in the Himalayas, where extreme weather in one nation can quickly become a disaster risk for its neighbour. Officials are urging residents in affected Bihar districts to stay alert and follow evacuation instructions if river levels continue to rise.
