Nepal floods: Whistles, shouts warned Trishuli folks as river rose 30ft in 30 mins

Whispers and shouts were the final warning for those living along the Trishuli and Bhote Koshi rivers in Nepal on Wednesday, as a flood originating from Nepal-Tibet swept downstream with disastrous consequences. At one monitoring point, the water level surged nearly 30 feet in just 30 minutes, leaving little time for residents to react.

The ICIMOD reported that the Trishuli river at Galchhi rose by up to nine meters within the same timeframe, and the Malekhu station recorded a seven-meter increase. Several monitoring stations were either damaged or washed away as the flood moved downstream. Despite the Nepal's early warning system sending out SMS alerts to riverbank communities in Rasuwa, Nuwakot, Dhading, and Chitwan, the upper-basin network was unable to provide timely advance notice.

Binod Parajuli, the senior divisional hydrologist at Flood Forecasting Division, revealed that automatic stations in the upper Bhote Koshi stopped transmitting before they could alert officials. While the warnings helped many people downstream, some areas still had to rely on their own observations and auditory cues. Parajuli admitted the uneven results, stating that Nepal failed to provide warnings in Rasuwa, but managed to send alerts to Nuwakot and downstream regions, potentially saving several hundred lives.

He emphasized the need for denser real-time monitoring and improved cross-border information sharing for sudden Himalayan hazards, suggesting that installing sensors extensively in the mountains and receiving notifications as soon as an event occurs could give people downstream enough time to seek safety. The Chinese Embassy rejected allegations that they failed to issue timely warnings about the devastating flood in the Rasuwagadhi-Kerung border area, dismissing the claims as "fake news" and "misleading".

They disputed two allegations that Nepal suffered heavy casualties due to the lack of an early warning from China, and that a geological disaster dam on the Chinese side collapsed, causing widespread destruction downstream in Nepal. The embassy clarified that a landslide triggered by an earthquake or a tremor similar in nature occurred on the Nepali side early on August 26, 2026, and maintained that the blame was unproductive, and cooperation was crucial for saving lives.
