Reports now say the flooding in Bhutan caused no injuries, while flood fears in Assam and West Bengal eased. NDTV India reported vulnerable areas in Assam were safe, and The Times of India Kolkata reported the Sankosh was receding and Bengal had been spared the impact. Bhutan's Punakha Dzong has closed until further notice as a public safety measure, according to World News CNA.

How it started

A glacial lake outburst occurred at Shintaphu Lake in Bhutan on Thursday evening, October 29, according to Mint. The lake lies at the source of the Mo Chhu River in the high-altitude Gasa district.

The reported outburst prompted concern downstream in India. India Today reported that districts in Assam and West Bengal had been placed on flood alert.

How it unfolded

On October 29, Bengal forest minister Manoj Oraon warned residents near the Sankosh River following the lake outburst, Times of India reported. People in the Kumargram area were advised to remain alert.

Coverage that day also described a wider watch across low-lying districts of Assam and West Bengal. Times now reported that authorities were monitoring rivers carrying large volumes of water.

By October 30, Times of India Top Stories described north Bengal as being on red alert as the flood threat continued.

The response also included evacuation warnings. The Hindu reported on October 30 that West Bengal authorities had issued high-alert and evacuation warnings for residents along the Sankosh River.

Where it stands

The latest coverage places riverside communities in West Bengal under warning, with Assam also facing flood alerts. The most specific guidance reported concerns residents along the Sankosh River, according to The Hindu.

The supplied reports do not establish how many people have evacuated or provide confirmed figures for casualties or damage. They describe a flood threat and an active warning response, rather than a measured account of the downstream impact.

What to watch

The immediate questions are how river conditions develop and whether evacuation warnings lead to confirmed movements of residents. Times now reported river monitoring, while The Hindu reported evacuation warnings along the Sankosh. Further official updates are needed to establish the extent of flooding downstream.
