The warning comes after a glacier collapse in Tibet triggered devastating flash floods and mudslides along the China-Nepal border

A barrier lake formed near the confluence of the Chhochen Khola and Purepu Tsangpo rivers in Nepal faces a potentially high risk of breaching over the next three days, Chinese authorities have warned, raising concerns of further flooding in the region.

China’s Ministry of Water Resources said the lake had accumulated around 2 million cubic metres of water by Thursday morning and was already overflowing. Another 3 million cubic metres could flow into the lake over the next three days, according to state broadcaster CCTV.

Authorities are closely monitoring the lake and conducting flood simulations and risk assessments to prepare for a possible breach and support emergency rescue operations.

The warning comes after a glacier collapse in Tibet triggered devastating flash floods and mudslides along the China-Nepal border. At least 273 people have died and more than 1,300 remain missing, although figures differ between agencies.
