Bhutan Glacial Lake Outburst Flood Prompts Flood Warning in West Bengal and Assam

A glacial lake outburst flood (GLOF) originating in the Himalayan kingdom of Bhutan has triggered official flood warnings for the Indian states of West Bengal and Assam. Meteorological and disaster management agencies in the two states have alerted residents to the heightened risk of rising water levels in rivers that flow from Bhutan into Indian territory.

The warning comes as authorities monitor river flows in the Brahmaputra basin, which receives meltwater from Bhutanese glaciers. Local administrations have advised communities in low‑lying areas to stay vigilant, keep emergency kits ready, and follow instructions from disaster response teams.

While no immediate damage has been reported, the precautionary alert underscores the vulnerability of the region to transboundary glacial melt events. Officials continue to track the situation closely and will update the public if conditions change.

The incident highlights the growing need for coordinated monitoring of glacial lakes in the Himalayas, given the potential for rapid water release to affect downstream populations across national borders.

Residents are urged to stay informed through official channels and to cooperate with any evacuation or safety measures that may be announced.
