Nepal Flood Map | August 26, 2026 | Live Disaster Information
The Nepal flood map 2026 is rapidly changing as a catastrophic flash flood has struck northern Nepal, particularly Rasuwa District and the Bhotekoshi River corridor, following a sudden surge of water from the Tibet side of the Nepal–China border.
The disaster has destroyed or damaged homes, roads, bridges, businesses, hydropower infrastructure and border facilities. The flood has also affected the Tibet region of China, including the Gyirong area, making this a major cross-border Himalayan disaster. Reuters reports that at least 95 people have died in Nepal and hundreds remain missing, while AP reports at least 98 deaths across Nepal and China.
This page explains where the Nepal flood happened, which districts are affected, how the Bhotekoshi and Trishuli rivers are connected, where flood risks may extend, and how to interpret the Nepal flood map today.
LIVE UPDATE: This is a developing disaster. Flood-affected areas, river levels, road conditions, missing-person figures and evacuation requirements can change rapidly. Always verify current conditions with official authorities before travelling.
Nepal Flood Map Today: Where Is the Flood?
The most severely affected area currently reported is Rasuwa District in northern Nepal, close to the border with Tibet.
The sudden flood surged into the Bhotekoshi River and swept through areas including Timure and Syabrubesi, causing extensive damage.
The flood also affected the Rasuwagadhi border area, an important Nepal–China crossing and trade corridor.
Current reporting indicates that the flood originated from the Tibetan side before entering Nepal through the Bhotekoshi system.
Key locations to identify on the Nepal flood map
- Tibet Autonomous Region, China
- Gyirong / Kerung area
- Rasuwagadhi
- Timure
- Syabrubesi
- Rasuwa District
- Bhotekoshi River
- Lhende River
- Trishuli River
- downstream areas of Rasuwa
- Nuwakot
- Dhading
- other downstream river communities
Nepal Flood Map: Tibet to Rasuwa
The geography of this disaster is important because the flood did not begin as an ordinary rainfall event in central Nepal.
The reported sequence is broadly:
Tibet → Lhende River → Bhotekoshi River → Rasuwa → downstream river system → Trishuli
Reports indicate that a sudden high-volume surge entered the Bhotekoshi River from Tibet.
This explains why searches for both:
“Tibet flood”
and
“Nepal flood”
are rising simultaneously.
The two events are geographically connected.
Gyirong and Tibet Flood Map
The northernmost part of the affected area is in the Tibet Autonomous Region of China.
One of the important locations is Gyirong, near the Nepal–China border.
Reports indicate that severe flooding and debris affected the Gyirong Port area, damaging infrastructure and disrupting communications and power links.
This location is important when interpreting satellite images and online flood maps because the event crosses an international boundary.
A map showing only Nepal does not tell the full story.
The upstream source area is across the border in Tibet.
Rasuwa Flood Map
Rasuwa District is currently the main disaster zone on the Nepal side.
The district is located in the Himalayan region north of Kathmandu.
The most prominent locations affected by the flood include:
Timure
Timure is located along the Nepal–China border corridor and has suffered severe damage.
Rasuwagadhi
Rasuwagadhi is an important border crossing between Nepal and China.
Syabrubesi
Syabrubesi is one of the major settlements and transportation points in Rasuwa.
Bhotekoshi River corridor
The river corridor has experienced a sudden and destructive rise in water levels.
Kathmandu Post reporting confirms that the sudden Bhotekoshi surge damaged settlements and infrastructure in Timure and Syabrubesi and prompted warnings for communities downstream along the Trishuli River.
Bhotekoshi Flood Map
The Bhotekoshi River is at the centre of the current Nepal flood disaster.
The river originates in the high Himalaya and flows from Tibet into Nepal.
During the August 26 disaster, water levels increased extraordinarily quickly.
The sudden nature of the event is one of the most important characteristics of the flood.
This was not simply a slowly rising river that gave communities hours or days to prepare.
A sudden upstream release can produce a powerful flood wave capable of carrying:
- rocks;
- mud;
- trees;
- vehicles;
- buildings;
- bridge components;
- debris.
That combination makes a Himalayan flash flood particularly destructive.
Where Is Bhotekoshi River?
The Bhotekoshi flows through northern Nepal after entering from the Tibetan side.
For the current disaster, the most important section is the river corridor through Rasuwa District.
The river's connection to downstream waterways is also important because floodwater does not remain confined to the original location.
A major surge can move downstream and affect communities much farther from the initial disaster zone.
Trishuli Flood Map
The Trishuli River is one of the major downstream concerns following the Rasuwa flood.
Authorities have warned communities along the Trishuli River to take precautions as water levels may rise. Kathmandu Post reported warnings to people working or fishing in the river and to communities, hydropower facilities and infrastructure along its banks.
This means people searching:
“Trishuli flood”
or
“Trishuli flood today”
should not assume that the absence of flooding in Kathmandu means there is no downstream risk.
River conditions can change rapidly.
Which Districts Are at Risk?
Reports indicate that authorities have placed multiple downstream districts on alert.
Areas mentioned in current reporting include:
- Rasuwa
- Nuwakot
- Dhading
- Chitwan
- other communities along downstream river corridors
One report stated that the flood moved downstream toward the Trishuli River and that multiple districts were placed on alert.
However, an alert does not mean that every location within a district is flooded.
This distinction is important when reading online maps.
A district can be placed on high alert because of potential river flooding even when most settlements remain unaffected.
Nepal Flood Map: Affected Areas vs. Alert Areas
When looking at a Nepal flood map, it is useful to divide locations into three categories.
🔴 Category 1: Directly affected areas
These are locations where flooding and destruction have already been reported.
Examples include parts of:
- Timure
- Syabrubesi
- Rasuwagadhi
- Bhotekoshi river corridor
🟠 Category 2: Downstream risk areas
These are locations where authorities are monitoring potential floodwater movement.
These include parts of the:
- Trishuli corridor
- Nuwakot
- Dhading
- downstream settlements
🟡 Category 3: Wider warning areas
These are areas where authorities may advise residents to remain alert because river conditions could change.
A flood warning should not automatically be interpreted as confirmed flooding.
Nepal Flood Map and Kathmandu
A major question being searched online is:
“Is Kathmandu affected by the Nepal flood?”
The current disaster's primary impact is in northern Nepal, particularly Rasuwa and downstream river corridors.
Kathmandu itself is not the epicentre of the Rasuwa flood.
However, Kathmandu residents may still be concerned because:
- Rasuwa is geographically close to the Kathmandu Valley;
- major rivers connect northern mountain areas with downstream systems;
- road and transport routes can be disrupted;
- displaced people may move toward Kathmandu;
- emergency services may be mobilised from Kathmandu;
- weather and river conditions can change.
Therefore, people in Kathmandu should distinguish between direct flooding in the city and the wider national emergency.
Nepal Flood Map: Road and Transport Disruptions
A flood map should not only show water.
For travellers, the more useful question is:
Which roads and crossings are currently safe or operational?
The Rasuwa flood has severely affected the northern border corridor.
Damage has been reported to roads, bridges and other infrastructure. Reuters reported extensive destruction to infrastructure on both sides of the Nepal–Tibet border.
Travellers should therefore avoid relying on old Google Maps travel times.
A road shown as open on a conventional navigation application may be:
- damaged;
- blocked;
- inaccessible;
- unsafe;
- closed by authorities.
Nepal–China Border Flood Map
The current disaster is also a Nepal–China border emergency.
The affected area includes the important Nepal–China trade and travel corridor through:
Rasuwagadhi ↔ Gyirong
The flood has caused severe disruption around this border region.
This explains why search interest has expanded from:
Nepal flood
to:
China flood
and:
Tibet flood.
Reuters reports that the flood and associated debris affected the Gyirong border area and disrupted communications and power infrastructure.
Why the Nepal Flood Map Is Difficult to Update
A conventional flood map may not immediately show the full disaster.
There are several reasons.
1. Remote terrain
Much of northern Nepal is mountainous and difficult to access.
2. Communication failures
Flooding can damage telecommunications and electricity.
3. Rapidly changing river conditions
A location that was safe in the morning can become dangerous later.
4. Limited ground observations
Rescue teams cannot immediately inspect every settlement.
5. Satellite limitations
Cloud cover, image timing and image resolution can affect satellite-based flood mapping.
6. Administrative boundaries
A district-level map may show an entire district as “affected” even though only particular river corridors are experiencing flooding.
For this reason, a good Nepal flood map should combine:
satellite information + official alerts + ground reports + river monitoring + verified news reports.
What Caused the Nepal Flood?
The exact mechanism continues to be investigated, but current scientific and media reporting points toward a sudden high-mountain event in the Lhende River system.
Reuters reports that an earthquake-induced ice-rock avalanche caused the catastrophic flood, while other reporting has described an ice avalanche or glacial process as the suspected trigger.
The sequence may have involved:
earthquake or slope instability
↓
ice-rock avalanche
↓
temporary blockage / sudden water accumulation
↓
rapid release of water
↓
Lhende River surge
↓
Bhotekoshi flood
↓
destruction downstream
The precise sequence should continue to be treated as subject to scientific verification.
Was This a Glacial Lake Outburst Flood?
This is one of the most important questions surrounding the disaster.
A glacial lake outburst flood (GLOF) occurs when water stored behind or within a glacial system is suddenly released.
The current event has been described in some reports as an avalanche-connected glacial surge or possible glacial-lake-related event. AP reported that the flood was triggered by an avalanche-connected glacial surge.
However, it is important not to state prematurely that a conventional GLOF has been definitively established.
The exact hydrological and geological mechanism requires further investigation.
Nepal Flood Map and Climate Change
The disaster also raises questions about climate change and Himalayan flood risk.
The Himalaya is warming rapidly, affecting glaciers, snow, ice, permafrost and high-altitude hydrology.
But it is scientifically inappropriate to say:
“Climate change caused today's flood.”
The immediate trigger may instead have been an avalanche, landslide, earthquake-related instability or sudden glacial water release.
A more accurate statement is:
Climate change can alter the conditions that influence high-mountain hazards, while the immediate trigger of a particular flood must be established through geological and hydrological investigation.
The current event demonstrates why Himalayan countries need stronger:
- glacier monitoring;
- early-warning systems;
- river sensors;
- satellite observation;
- avalanche monitoring;
- seismic monitoring;
- community warning systems.
Nepal Flood Map: Hydropower Projects Affected
The Bhotekoshi and surrounding Himalayan valleys contain important hydropower infrastructure.
The current flood has damaged hydropower projects and related infrastructure.
This is significant because Nepal has invested heavily in hydropower development along mountain rivers.
Flood risk therefore affects not only communities but also:
- electricity generation;
- transmission infrastructure;
- access roads;
- bridges;
- construction projects;
- national energy security.
Current reporting confirms that hydropower projects in Rasuwa were damaged by the sudden flood.
Nepal Flood Map: Humanitarian Impact
The map of the disaster is ultimately a map of people, not just rivers.
Hundreds of people remain missing.
AP reports that 403 people were reported missing in Nepal, including 341 foreign nationals, while three people died in Tibet and 265 were reported missing there.
This includes travellers and pilgrims who were in the Himalayan border region.
As search-and-rescue teams reach isolated areas, the geographic picture of the disaster will continue to develop.
Nepal Flood Map for Tourists and Trekkers
If you are planning travel to northern Nepal, do not rely solely on a static online map.
The areas around:
- Rasuwa;
- Syabrubesi;
- Timure;
- Rasuwagadhi;
- Bhotekoshi;
- Langtang approaches;
- Tibet border routes
should be treated with extreme caution while the emergency response continues.
Check official travel advisories and local authorities before travelling.
A road that appears visually intact on an old map may have been damaged by a flood or landslide.
Nepal Flood Map: What Areas Should People Avoid?
During an active flood emergency, people should avoid:
- riverbanks;
- bridges over swollen rivers;
- recently flooded roads;
- unstable slopes;
- damaged buildings;
- hydropower facilities;
- restricted border areas;
- debris-flow channels;
- isolated mountain roads.
Do not attempt to travel into Rasuwa simply to observe or photograph the disaster.
Rescue teams need unobstructed access to affected locations.

Nepal Flood Map: How to Read Satellite Images
Satellite imagery can be extremely useful during disasters.
Before-and-after imagery can reveal:
- river widening;
- washed-out roads;
- destroyed bridges;
- sediment deposits;
- changes in river channels;
- damaged settlements;
- landslides;
- debris fields.
However, satellite imagery should not be interpreted without considering the image date.
A satellite image captured before August 26, 2026 cannot show today's flood damage.
Likewise, an image captured during cloud cover may not provide a reliable view.
For Recent Natural Disasters, every satellite image used should therefore include:
Image date + source + location + interpretation.
