New Delhi, Oct. 30 -- A glacial lake outburst flood (GLOF) reported in northwestern Bhutan has triggered emergency flash-flood warnings across the border in the Indian states of West Bengal and Assam.

According to an NDTV report, prompt evacuations prevented casualties, but disaster management agencies are on high alert along the transboundary Himalayan river systems.

Here's all you need to know about it:

As the Mo Chhu flows southward out of Bhutan, it joins the Pho Chhu to form the Punatsangchhu, which eventually enters India as the Sankosh River before emptying into the Brahmaputra.

Bhutan immediately alerted Indian authorities about the approaching surge, prompting high alerts in districts bordering the Himalayan nation.
