- Description: The Trishuli River at Galchchi station rose nine metres in thirty minutes. At Malekhu, seven metres in the same window. Those numbers, recorded by hydrological sensors along Nepal's Rasuwa district on 26 August 2026, describe a valley floor remade in a single event.

TLDR

Flash floods tore through Nepal's Rasuwa district into Tibet, killing roughly 469 people and leaving at least 39 Australians unaccounted for. A debris blockage on the Nepal, China border has formed a new glacial lake, and authorities warn a second surge is imminent. Australia's Foreign Affairs Minister Penny Wong has deployed a Crisis Response Team to Kathmandu.

KEY TAKEAWAYS

01At least 39 Australians are missing, up from 35 listed by Nepal's Ministry of Foreign Affairs the previous day.

02359 bodies had been recovered from Rasuwa district river areas by 27 August 2026.

03Water on the Trishuli River at Galchchi rose nine metres within thirty minutes of the initial flood event.

04A debris blockage near the Nepal, China border has formed a new glacial lake, with evacuation orders issued for Jilong port.

05Families in Australia can call the Consular Emergency Centre on 1300 555 135 for assistance.

## A valley swallowed in thirty minutes

The Trishuli River at Galchchi station rose nine metres in thirty minutes.[\[1\]](https://www.icimod.org/press-release/major-flash-flood-sweeps-through-nepals-rasuwa-district-raising-fears-of-further-downstream-flooding/?ref=bushletter.com) At Malekhu, seven metres in the same window. Those numbers, recorded by hydrological sensors along Nepal's Rasuwa district on 26 August 2026, describe a valley floor remade in a single event.

359 bodies had been recovered from the river areas of Rasuwa district by 27 August 2026, with the overall death toll across Nepal and Tibet approaching 469.[\[2\]](https://www.mofa.gov.np/content/1863/latest-updates-on-flash-floods-27-august-2026/?ref=bushletter.com) Hundreds more remain unaccounted for. The flood hit during the peak Himalayan trekking season, when pilgrims and adventure travellers fill the border corridors en route to Mount Kailash and Lake Manasarovar.

## Ice, rock and an avalanche trigger

Scientists at the International Centre for Integrated Mountain Development (ICIMOD) are analysing satellite and seismic data to understand how an ice-rock avalanche in the Lhende Khola set off the cascade.[\[1\]](https://www.icimod.org/press-release/major-flash-flood-sweeps-through-nepals-rasuwa-district-raising-fears-of-further-downstream-flooding/?ref=bushletter.com) Nepal's monsoon, which runs June to August, swells rivers and accelerates glacial melt across the Hindu Kush Himalaya, compressing the margin between a stable glacial lake and an outburst flood.

Copernicus Sentinel-2 satellite imagery, comparing scenes from 12 August and 27 August, shows the river channel near Betrawati and Gerkhu had widened markedly, with extensive sediment deposits blanketing the valley floor.[\[3\]](https://eu-space.europa.eu/components/earth-observation-copernicus/image-of-the-day/aftermath-nepal-flash-flood?ref=bushletter.com) The visual record confirms what the hydrological data suggested: a single event reshaped the terrain.

## A second flood is imminent

A debris blockage lodged on the Nepal, China border has formed a new glacial lake upstream, and authorities have issued evacuation orders for Jilong port in anticipation of a second surge. Qianggong Zhang, Head of Climate and Environmental Risks at ICIMOD, said the blockage still lodged upstream means a second flood is imminent, with evacuation orders now in place for Jilong port.[\[1\]](https://www.icimod.org/press-release/major-flash-flood-sweeps-through-nepals-rasuwa-district-raising-fears-of-further-downstream-flooding/?ref=bushletter.com)

ICIMOD Director General Pema Gyamtsho said the organisation stands in solidarity with the people and Government of Nepal, with thoughts for the victims, their families and all those affected, and is committed to providing support wherever possible.[\[1\]](https://www.icimod.org/press-release/major-flash-flood-sweeps-through-nepals-rasuwa-district-raising-fears-of-further-downstream-flooding/?ref=bushletter.com) Temporary landslide dams in narrow Himalayan valleys can release without notice once water pressure or seismic activity destabilises the debris barrier, giving downstream communities very little warning time.

## 39 Australians unaccounted for

Nepal's Ministry of Foreign Affairs listed 35 Australians among the foreign nationals still missing in the Bhote Koshi River flood as of 27 August.[\[2\]](https://www.mofa.gov.np/content/1863/latest-updates-on-flash-floods-27-august-2026/?ref=bushletter.com) The Department of Foreign Affairs and Trade revised that figure upward the following day. As of 28 August, DFAT confirmed at least 39 Australians are among those reported missing in the Nepal, China floods.[\[4\]](https://www.foreignminister.gov.au/minister/penny-wong/media-release/australias-response-nepal-china-floods?ref=bushletter.com)

Foreign Affairs Minister Penny Wong said Australian officials are working urgently to confirm the welfare of those affected and provide assistance.[\[4\]](https://www.foreignminister.gov.au/minister/penny-wong/media-release/australias-response-nepal-china-floods?ref=bushletter.com) DFAT is deploying a Crisis Response Team member and a Regional Consular Officer to Kathmandu to support affected Australians and their families.[\[4\]](https://www.foreignminister.gov.au/minister/penny-wong/media-release/australias-response-nepal-china-floods?ref=bushletter.com)

Families in Australia seeking information can call the Consular Emergency Centre on 1300 555 135, or +61 2 6261 3305 from overseas. The Australian Embassy in Kathmandu can be reached directly on +977 1 437 1678.[\[5\]](https://www.smartraveller.gov.au/destinations/asia/nepal?ref=bushletter.com) The Smartraveller advisory for Nepal remains active, and travellers and their families are advised to check it for updated guidance.

FREQUENTLY ASKED QUESTIONS

How many Australians are missing in the Nepal floods?

As of 28 August 2026, DFAT confirmed at least 39 Australians are among those reported missing following the Rasuwa district flash floods on the Nepal, China border.

What caused the flash floods in Nepal's Rasuwa district?

ICIMOD scientists are investigating an ice-rock avalanche in the Lhende Khola as the likely trigger. The avalanche sent a surge down the Bhote Koshi River system, raising the Trishuli River at Galchchi by nine metres in thirty minutes.

Is there a risk of further flooding?

Yes. A debris blockage near the Nepal, China border has formed a new glacial lake. Authorities have issued evacuation orders for Jilong port and ICIMOD warns a second flood surge is imminent.

How can families in Australia get help?

The Consular Emergency Centre can be reached on 1300 555 135 within Australia or +61 2 6261 3305 from overseas. The Australian Embassy in Kathmandu is on +977 1 437 1678.
