A barrier lake near the Chhochen Khola and Purepu Tsangpo rivers in Nepal has accumulated approximately 2 million cubic meters of water and is overflowing, with an additional 3 million cubic meters expected over three days. Chinese authorities are monitoring the site and conducting flood simulations following a glacier collapse that triggered flash floods and mudslides. Reports indicate at least 273 deaths and more than 1,300 people missing across China and Nepal.
