Important Weather Notice
Weather conditions, rainfall forecasts and river levels can change quickly. NepalFloodNews.com does not replace official weather warnings.
Always check the latest Department of Hydrology and Meteorology information before making travel or safety decisions.
Nepal Weather Situation
Nepal's geography makes weather conditions very different between the Himalayan region, hills and southern plains.
During the monsoon season, heavy rainfall can raise river levels and increase the risk of flash floods, landslides, road closures and local inundation.
Flood-affected areas can remain vulnerable even after rainfall temporarily stops because damaged slopes, blocked rivers and unstable debris can create additional hazards.

View DHM →Understanding Nepal Flood Warning Levels
DHM flood monitoring tracks river conditions and indicates whether monitored water levels are below warning level, above warning level or above danger level.
Below Warning Level
The monitored river is below the official warning threshold. Conditions can still change if rainfall increases.
Warning Level
Increased attention is required. People near rivers should monitor official instructions closely.
Danger Level
A serious flood risk may exist. Follow evacuation or safety instructions issued by authorities.
Why Weather Matters After a Major Flood
Rainfall after a major flood can create additional problems even when the original floodwater has gone down.
Additional rainfall can:
- Increase river levels.
- Trigger new landslides.
- Weaken already damaged slopes.
- Move debris downstream.
- Damage temporary roads or bridges.
- Delay rescue and relief operations.
Heavy Rainfall & Flash Flood Risk
Flash floods can develop quickly, particularly in steep valleys and mountain catchments.
Heavy rainfall upstream can create dangerous conditions downstream even if little rain is falling at your own location.
This is why river-monitoring and upstream weather information can be as important as the weather directly overhead.
Weather & Landslide Risk
Heavy or prolonged rainfall can saturate steep slopes and increase the chance of landslides.
People travelling through mountain districts should be especially careful around:
- Fresh cracks in roads or slopes.
- Falling rocks.
- Mud or water flowing across roads.
- Damaged retaining walls.
- Previously flooded slopes.
Weather Risks by Region
| Region | Main Weather Concern | What to Monitor |
|---|---|---|
| Himalayan Region | Flash floods, ice/rock hazards and landslides | Rainfall, river conditions and official alerts |
| Hill Region | Landslides and road disruption | Heavy rainfall and slope conditions |
| Terai Region | River flooding and inundation | River levels and rainfall forecasts |
| Flood-Affected Areas | Renewed flooding and damaged slopes | Local alerts and upstream river conditions |

What to Do During a Weather or Flood Alert
Use DHM and local-authority information instead of relying only on social media posts.
Never attempt to walk or drive through fast-moving water.
Follow evacuation instructions if flooding threatens your location.
Stay away from areas showing signs of landslide or rockfall activity.
Flooding and landslides can close roads with little warning.
Keep safe water, essential medication, lighting and important documents ready.
How Nepal Flood News Handles Weather Updates
Weather forecasts become outdated quickly. For that reason, NepalFloodNews.com does not permanently publish a forecast as if it remains current.
Our weather pages explain risks and link users to official real-time sources. When we publish a specific warning or forecast, we show the date of the information and update or remove it when conditions change.
Primary Weather Source
Our primary source for Nepal weather and river information is the Government of Nepal's Department of Hydrology and Meteorology.
Official DHM resources include weather forecasts, hydrological forecasts, flood monitoring and flood warning information.
