Officials have said that the floods inflicted extensive damage in Rasuwa.

The details of the damage caused by the floods, however, are yet to come.

National Disaster Risk Reduction and Management Authority spokesperson Suresh Sunar said that the initial report stated that 18 people are missing.

“Teams from all three security agencies have been mobilized to search the missing persons and rescue those trapped in the floods,” said Sunar.

“Miteri Bridge connecting Nepal and China in Rasuwagadhi has been washed away, and the Timure dry port and some hydropower plants have also been damaged,” he said.

According to Dhruba Prasad Adhikari, Assistant Chief District Officer of Rasuwa, the damage was caused by the flash flood triggered by incessant rainfall at around 3 am. Vehicles in the dry port were swept away. The drivers and assistant drivers of those vehicles were also caught in the flood.

Videos posted on social media also show vehicles being swept away in the floodwaters, people trapped in the floodwaters trying to escape by climbing trees, and Nepal Army helicopters rescuing them.

Kaisang Nurpu Tamang, Chairman of Gosainkunda Rural Municipality in Rasuwa, said that rescue and relief works have been affected as the floods and landslides obstructed roads in several places.

Police said that the landslides completely obstructed Syafrubeshi-Rasuwagadhi road section alson the Pasanglhamu Highway

Meanwhile, officials said that the damage caused by the floods in Rasuwa was not due to rain on Nepali territory.

Officials from the Disaster Management Authority and the Department of Hydrology and Meteorology have initially estimated that there may have been heavy rain in neighboring China or that the dam may have burst, leading to the flood.

Disaster Management Authority spokesperson Suresh Sunar said that since there was no information about heavy rain in Nepal, something might have occurred in China.

Pratibha Manandhar, a senior meteorologist at the Department of Hydrology and Meteorology Weather Forecasting Division, said that there has not been enough rain to cause major flooding in Nepal.

"It appears that less than 30 millimeters of rain has occurred in the area in the past 24 hours," she said. "This much rain will not cause that much flooding." According to her, only light to moderate rain has occurred in Rasuwa and its neighboring districts.

Employees of the Flood Forecasting Division have also speculated that heavy rain may have occurred on the Chinese side or that a dam may have burst and the Bhotekoshi River may have flooded.
