Nepal Flash Floods Kill Seven, Nearly 400 Missing as Glacial Outburst Devastates Rasuwa

The Bhote Koshi River, which flows from Tibet through Nepal's Rasuwa district, turned violent without warning on Wednesday morning. At around 9 am local time, a sudden surge of water tore through the main market area of Rasuwa and the settlement of Syaprubesi, destroying homes, shops, and infrastructure along its path. There had been no rain in the region. The sun was shining. Yet the water came anyway—a wall of it, moving fast enough to sweep away everything in its way.

Narendra Pariyar, the Chief District Officer of Rasuwa, spoke to reporters in the hours after the flood hit. He described the damage as extensive but said precise details were still arriving. "It has not rained here," he said. "The sun is shining here. It is not clear whether the glacier burst upstream or what happened. The flood was sudden." The cause remained unclear, though officials suspected a glacial outburst on the Tibetan side of the border—a phenomenon where a sudden release of meltwater or a glacier collapse sends a torrent downstream with little or no warning.

The human toll mounted quickly. By Wednesday afternoon, at least seven people were confirmed dead. The Nepal Tourism Board reported that 384 travelers had gone missing in the disaster: 291 foreigners and 93 Nepalese nationals. Among the missing were Indian nationals and non-resident Indians. Four personnel from an Armed Police Force border outpost in northern Rasuwa were also unaccounted for. Against this, rescue teams had managed to pull 25 people to safety by midday.

The flood did not stop at Rasuwa. It surged downstream through Dhading district and into Nuwakot, southwest of Kathmandu, affecting multiple communities along the river's path. At least a dozen hydropower projects sustained damage, disrupting power generation across the region. The scale of the disaster forced authorities to issue evacuation orders for residents living along riverbanks in five districts, including Chitwan, as water levels remained dangerously elevated.

The response mobilized Nepal's security apparatus. The Nepali Army, the Armed Police Force, and local police were deployed for search-and-rescue operations. Fourteen helicopters were put into service to reach remote areas and transport rescued people to medical facilities. The military and police worked through Wednesday afternoon and into the evening, racing against time to locate missing travelers and residents before nightfall made rescue efforts more difficult.

The disaster exposed the vulnerability of communities and travelers in border regions where glacial hazards can strike with little warning. Rasuwa district, which sits on the Nepal-Tibet border, is a transit point for trekkers and traders moving between the two countries. The market area that was hit on Wednesday morning is a commercial hub for the region. The sudden flood transformed it into a scene of wreckage within minutes. As rescue operations continued, the full scope of the missing remained uncertain—some may have been swept downstream, others may have taken shelter in higher ground. The search would take days.
