A significant glacial lake outburst at Sintaphu Lake in Bhutan's Mochu sub-basin has raised alarms in the neighboring Indian states of West Bengal and Assam, prompting authorities to issue flash flood warnings. The outburst, which occurred recently, is estimated to have released around 7.4 million cubic metres of water, a volume substantial enough to pose serious risks to downstream areas.

Sintaphu Lake, located at the source of the Mo Chhu River, is classified as one of Bhutan's 17 potentially dangerous glacial lakes. The potential for such outbursts is a growing concern in the region, especially given the impacts of climate change on glacial stability and water levels. Local officials are closely monitoring the situation to mitigate any possible flooding effects on communities in West Bengal and Assam.S2S3

The warnings come as part of a broader effort to prepare for and respond to the increasing frequency of glacial lake outburst floods (GLOFs) in the Himalayas, which have been exacerbated by rising temperatures. As the situation develops, residents in the affected areas are urged to stay vigilant and heed any evacuation orders or safety advisories issued by local authorities.S1S3
