On August 26, 2026, a catastrophic flash flood swept down from the Bhote Koshi River near the Nepal-Tibet border, tearing through Rasuwa, Nuwakot, and Dhading districts in Nepal and destroying entire villages within minutes, leaving thousands missing and hundreds dead. This account is by Dikshya Subedi, a local in Kathmandu who has spent the past seven years working in climate advocacy across the Himalayan region. She is the country lead at SHE Changes Climate and founder of the youth-led organization Youth Action For Sustainable and Eco Nepal (YASEN), and writes here as someone whose own family was directly affected by the disaster. That Wednesday morning started like any other. At around 9:30 AM, I saw the first news of a massive flood in Rasuwa, the beautiful mountainous district on the Tibet border. Lined with brightly coloured houses and where the Bhote Koshi River enters Nepal, Rasuwa is located a few hours from Kathmandu. Feeling confused and unsettled, I scrolled on, the way we sometimes do when something feels too big to look at directly. A few minutes later, my eyes landed on Facebook again, and this time the news was impossible to scroll past. The flash flood had hit Devighat, Nuwakot, a quiet riverside town further downstream where my husband was born and grew up in, the place that held his entire childhood. I called my aunt, who lives in Nuwakot. Her voice on the phone was shaking, terrified. ‘Nothing is left,’ she told me. ‘Everything is destroyed.’ Somehow, my uncle, aunt, and brother Manzil Rimal managed to evacuate from that flooded area just before the massive flood. But that phone call broke something in me. The place where we used to visit my husband’s hometown for festivals, where we gathered as a family, where his memories live, turned into mud in ten minutes.

I’ve explained flood risks to government officials, helped authorities understand the danger maps for glacial lakes, and used the phrase ‘climate crisis’ more times than I can count. But watching the impacts of the climate crisis arrive at your own doorstep, was beyond anything I could have imagined. I have spent years telling other people this could happen to them. I never imagined I would be the one making the phone call, listening to my aunt’s voice break on the other end. There is a saying in Nepal: disaster won’t come by making noise. On that Wednesday, the people of Rasuwa, Nuwakot, and Dhading learned exactly how true that is. And so did I, not as an advocate this time, but as a daughter-in-law of that soil. What happened A sudden, catastrophic flash flood surged in from the Bhote Koshi River near the Nepal-China border on the morning of August 26. It tore downstream through Timure, Syaphrubeshi, and Betrawati in Rasuwa district, sweeping away entire villages within an hour. The floodwaters continued down the Trishuli River corridor, devastating communities further downstream in the districts of Nuwakot and Dhading. Devighat, my husband’s village, was severely affected. Floodwaters caused severe devastation in Devighat. Photo: Dikshya Subedi While the exact cause is still being investigated, scientists have traced the flood back to an over 2,000-foot-wide (approx. 600 meters) chunk of glacier that sheared off high in the Himalayas and plunged 7,000 feet (over 2 kms) into the Lhende Khola a tributary of the Bhote Koshi River, sending a flood wave downstream at speeds of up to 193 km/h. This is exactly the kind of event climate change triggers. Warming shrinks glaciers and makes them more likely to break apart. The death toll from the devastating Bhote Koshi flood in Rasuwa has reached 939, while 3,925 people remain out of contact, according to the latest update from National Disaster Risk Reduction and Management Authority (NDRRMA). The highest number of bodies, 279, was recovered in Chitwan, followed by 216 in Nawalparasi Purba, 169 in Nawalparasi Paschim, 95 in Nuwakot, 65 in Gorkha, 55 in Dhading, 38 in Tanahun, and 23 in Rasuwa. Search and rescue teams, along with relief and medical response units, are still working around the clock. The government has set up dedicated teams for rescue, relief, health, communications, and infrastructure restoration, but the scale of destruction will take a long time to fully understand, let alone recover from. The floodwaters along with mud and debris completely destroy homes, reaching levels above the rooftops. Photo: Dikshya Subedi This is personal For me, this is not something I am following from a distance through headlines. My husband’s home is in Devighat, Nuwakot, one of the places hit hardest. My uncle, aunt, and brother were there and saw the destruction with their own eyes: houses swept away, communities losing almost everything in a matter of minutes. Thankfully, my close relatives are safe. We have not lost anyone in our own family. But we have lost our house and factory, which is the main source of income that my parents and Uncle Aunt took many years to built on is swept away in seconds. The place where we held countless family gatherings, where all of my husband’s childhood memories live, no longer exists.

A village once known for its bustling market and Jalpa Devi temple one of the very popular temple is buried under mud so complete that only the upper floors of houses still break the surface – uprooted trees flung onto rooftops, electric pylons snapped like twigs. Search teams there are still pulling bodies from collapsed homes, working through mud so thick that sometimes all that’s visible of a victim is a foot. Survivors who’ve come back describe standing in the wreckage of houses they spent their whole lives building, with nothing left to salvage but the clothes on their backs, unsure whether the land is even safe to rebuild on. Watching what has happened to our neighbors, to the village that shaped my husband’s childhood, is heartbreaking in a way I don’t fully have words for. The destruction left in Devighat in the aftermath of the flood. Photo: Dikshya Subedi This is the part that people rarely talk about when they discuss climate advocacy: the work is never as abstract as it looks from the outside. I have spent years building the language – resilience, adaptation, loss and damage – that is supposed to help policymakers understand disasters like this one. Advocacy taught me the facts. This flood taught me what the facts actually cost. Houses in Devighat left destroyed as mud and debris reach rooftops. Photo: Dikshya Subedi It’s not climate change anymore; it’s a climate emergency This disaster is a brutal reminder that climate change is not something we can keep filing away as a threat for later. We are already living its consequences here in the Himalayas. Global heating is melting the permafrost, the ‘glue’ that holds our mountains together, and that’s raising the risk of glacier collapse more and more likely. A survey published within a day of this flood has now mapped over 3,600 glacial lakes across our river basins, 47 of them classified as potentially dangerous, and this one wasn’t even on the list, because the lake that burst didn’t exist the morning before. That’s how fast this hazard is moving. Climate change makes flashfloods like the one above in Nuwakot more likely due to glacier collapse triggered by global heating. Photo: Dikshya Subedi What makes this especially unjust is the imbalanced cruelty of who pays: Nepal is responsible for roughly 0.1% of global greenhouse gas emissions, yet it ranks among the 10 countries most affected by climate change on the Global Climate Risk Index. Nepal’s finance minister, Swarnim Wagle, has put the initial rebuilding cost at US$4–5 billion, nearly a tenth of the country’s entire economy. But that estimate assumes this is a one-time cost. It isn’t. With the region’s glaciers and permafrost continuing to destabilize, a disaster like this one is not a low-probability outlier, it is the shape of what is coming again. There is still room for hope In the middle of all this grief, something has genuinely moved me: the response of young people.Within a day, young volunteers across Nepal had organized themselves into the Rasuwa Relief Group, tracking who was missing, making sure support reached those who needed it, even volunteering for risky ground operations. Locals and volunteers provide support and rescue in Devighat after the flood. Photo: Dikshya Subedi I’ve sat in plenty of meetings where ‘youth engagement’ was just a line on someone’s agenda, a box to check before the real decisions happened elsewhere. Watching this unfold in real time, I don’t need convincing anymore. No one assigned these young people this responsibility: they simply took it on, faster than any ministry could move, because these were their families too. It doesn’t erase my grief. But it has given me hope.It’s proof that the years I spent showing up to advocate for the climate as it affects young people,did build something – a generation that doesn’t wait to be asked. Things need to change now The flood that took my husband’s hometown moved at 193 kilometers an hour. We need to move faster. And for that, we need three things: Disaster preparedness and management: Climate response and preparedness cannot be the thing we get to eventually. It has to come first, before the next village disappears. We need early-warning systems, climate-resilient infrastructure, and locally led preparedness for the mountain communities already living with this risk. Locally led adaptation: Youth and affected communities must be given real, resourced roles in local adaptation and early-warning planning, not token invitations after the mourning has begun. Real climate finance: Wealthy nations, most responsible for the climate crisis, need to stop treating funding as a favor delivered on their own timeline. Nepal needs that money now, not at the next summit. It needs to come as genuine compensation, not charity, and paid out as grants rather than loans that burden our country. It must reach impacted families directly and fast. This isn’t a wish list; it’s the difference between a village saved in time and one that isn’t. My husband’s hometown is already gone. What we do next decides how many more we can save. Dikshya in Devighat.

But the people of Rasuwa, Nuwakot, and Dhading are still here, still fighting, still helping each other. Let’s unite to rebuild together.
