Flash floods in Nepal have killed at least five people and destroyed villages in the central Gorkha district after a pre-dawn landslide blocked the Budhi Gandaki River on 11 October. The disaster triggered severe downstream flooding, affecting hundreds and stranding trekkers.
Cause of the Nepal Flash Floods
A landslide early on 11 October created a natural dam on the Budhi Gandaki River. When the dam breached, water surged downstream, causing flash floods that caught residents off guard. River levels rose from 2 metres to nearly 8.5 metres within hours, according to the national disaster risk reduction and management authority.
Impact on Villages and Infrastructure
Two villages in the worst-affected Chumanubri rural municipality were reportedly destroyed. Homes, roads, and bridges were washed away, and part of a hydropower station was damaged. The floods affected over 650 people and damaged 204 homes. More than 100 foreign trekkers were stranded in the popular hiking region, though rescue efforts are ongoing.

Weather Bomb in Iceland: A Separate Event
Meanwhile, an exceptionally deep low-pressure system, known as a weather bomb, barrelled towards Iceland this week. Central pressure dropped to 931mb on 14 October, plummeting 49mb in 24 hours—meeting the threshold for explosive cyclogenesis. The system brought sustained winds of 55–60mph to southern shores before moving towards Norway. Fortunately, Iceland was spared the strongest winds.
