What we know
- Khabarhub reported that water levels in several major rivers are predicted to rise significantly over a three-day period.
- According to the Flood Forecasting Division, a moderate threat of flash floods exists for small rivers and streams.
- The rising waters are expected to affect twenty-two districts across Nepal.
- The official warning highlights increased water volume specifically within the Koshi and Narayani river basins.
What this means if you are travelling
- Travellers planning treks near watercourses in the Koshi and Narayani basins must exercise extreme caution over the next three days.
- Hikers should avoid camping near small streams and low-lying riverbanks in the twenty-two affected districts.
- Those booked on rafting or riverside activities should contact their guides to confirm if their specific itineraries remain safe.
- Travellers staying in major urban areas or high-altitude ridges away from small streams are unlikely to experience direct disruptions.
Authorities in Nepal have issued an advisory regarding rising water levels in multiple major river systems across the country. According to reporting by Khabarhub, official hydrologists expect a notable surge in water volume over a three-day period starting today. This rise has prompted safety warnings for nearby communities and travellers who may be near these watercourses.
The Flood Forecasting Division has identified twenty-two districts that face a moderate threat of sudden overflows. Small streams and tributary rivers are highly susceptible to rapid changes in water volume during this period. Foreign visitors currently in Nepal need to monitor local weather alerts closely, especially when travelling through valleys or planning river-based excursions.
Affected River Basins and Regions
The primary areas of concern are concentrated around two major river systems. The Flood Forecasting Division highlighted that both the Koshi basin and the Narayani basin are experiencing significant increases in flow. These massive networks feed countless smaller streams across the eastern and central regions of Nepal.
Because the warning specifically targets small rivers and streams, even minor waterways that seem shallow can swell rapidly. Heavy rainfall in the upper hills can cause sudden surges downstream without warning. This makes riverside trails and low crossings particularly hazardous for the next few days.
What This Means for Trekking and Travel Plans
If you have an active trek or outdoor activity booked, you must take these hydrological changes into account. Trails that cross minor bridges or run parallel to stream beds require extra vigilance. It is highly recommended to consult with your trekking guides before setting out each morning.
We advise all travellers to review their planned routes to see if they cross any vulnerable waterways. If your itinerary involves river crossings in the twenty-two affected districts, consider adjusting your schedule. Always defer to the expertise of your local guides and the latest bulletins from the Flood Forecasting Division.
- Avoid setting up camp or resting near small streams and riverbanks.
- Check with your transport provider before traveling on roads that run alongside major river basins.
- Do not attempt to ford swollen streams on foot or in light vehicles.
- Maintain regular communication with your tour operator to receive real-time route updates.
Understanding the Duration and Severity
The current advisory spans a specific window of three days, during which the risk remains elevated. While the Flood Forecasting Division has categorized the risk of flash floods as moderate, the situation can change quickly depending on localized rainfall. It is essential to remain cautious even if the weather in your immediate vicinity appears clear.
This warning does not mean that all travel across Nepal must stop. Many high-altitude trails, ridge walks, and urban areas remain completely unaffected by rising river levels. By staying informed and making sensible adjustments, you can continue your journey safely.
