Landslides may be expected. Exposed railways and roads may be closed. Risk of slushflows is especially high in areas with more than 50 cm snow. The snow may in some places be fully water-saturated. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows. Heavy snowmelt is expected. Heavy rain is expected.
Area
Applies to Nordland og deler av Troms.
Instructions
Keep water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides.
Consequences
Landslides may be expected. Exposed railways and roads may be closed.
Water discharge is expected to increase because of rain and snowmelt. This may cause local inundation where river channels are filled with ice and because of frozen ground. It also may cause ice drift in streams, with subsequent local inundation. Local flooding and erosion damage. Large amounts of rain are expected in the warning area.
Area
Applies to Nordland og deler av Troms.
Instructions
Stay informed on the situation. Secure and/or move assets away from vulnerable areas (car, caravan along rivers/streams, basements). Cleaning of drainage paths and culverts is recommended. Keep away from rivers and streams with high flow.
Consequences
Local flooding and/or erosional damage in streams and small rivers. Stormwater in urban areas.
From Sunday afternoon increasing southwest severe gale force 9 to occasionally storm force 10, with local strong gust 30-40 m/s. Strongest wind expected Sunday evening and early Monday morning. Decreasing wind early Monday morning.
Area
Applies to Saltfjellet, Salten, Lofoten, Ofoten and Vesteraalen and Troms.
Instructions
Secure all loose objects. Avoid exposed places. Allow a lot of extra time for transportation and driving. Consider whether the journey is necessary. Follow advice and check status from transport operators. Check road reports (175.no). Be careful in coastal areas. In advance consider measures to limit damage.
Consequences
Larger loose items may be taken by the wind. Risk of damage to buildings and infrastructure. Cancelled departures for ferry, plane, or other transport expected. Bridges may be closed. Many journeys may have longer travel times. Blowing snow at higher altitudes causes reduced visibility and possibly convoys and/or closed roads. High waves may cause damage to infrastructure and buildings in the coastal zone. The strong wind may cause locally high waves in fjords and lakes.
Timeline
- Sunday, 23 January 15:00 - wind increases

On Monday we expect high avalanche danger for region Salten. Avalanche problem is wind drifted snow (slab avalanches) and wet snow (slab avalanches).
