When the same valleys keep flooding, that is a policy fact, not a weather fact.
Sourced analysis of Nepal's disasters: what happened, what it cost, what failed, and how long recovery actually takes. Every figure carries the outlet that published it and the hour it was true.
Bhote Koshi flood, 26 August 2026
Rock and glacier ice broke off Langtang Lirung, inside a Nepali national park, and fell into the Lhende Khola on the China border. The surge hit Rasuwagadhi before any warning went out. 1,410 confirmed dead in Nepal, 6,145 missing, 748 MW of hydropower damaged, and a warning from thirteen months earlier that was never acted on.

Disasters in Nepal
Why does Nepal flood so badly, so often?+
Nepal receives about 80% of its annual rainfall in the June-September monsoon, across some of the steepest river gradients on earth. Add glacial lake outburst floods from a warming Himalaya, landslide-dammed rivers that burst, and settlement patterns that put markets, roads and hydropower on the valley floor, and the same corridors are hit repeatedly.
What is a GLOF?+
A glacial lake outburst flood: meltwater ponded behind an unstable moraine or ice dam releases suddenly, sending a debris-laden surge down the valley. Nepal has 21 identified potentially dangerous glacial lakes. A related and increasingly common variant is a rock or ice avalanche falling into a river, damming it, and bursting the dam it just built, which is what happened on the Bhote Koshi in August 2026.
Where can I find live official disaster data for Nepal?+
The NDRRMA's BIPAD portal (bipadportal.gov.np) is the official incident database, and the Department of Hydrology and Meteorology publishes flood forecasts and river-level telemetry. Amarnepal is a static site and publishes analysis with timestamped figures, not live feeds, so for a moving event go to those sources and to the Kathmandu Post, Setopati and Onlinekhabar.
