Today, Feb. 28
closeSome landslides are expected. A few large slides may occur. 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. Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Heavy snowmelt is expected. The soil water content will increase due to snowmelt. This will increase the danger of (slushflows and) landslides and debris flows along rivers and streams, and in slopes where there is snowmelt.
Area
Applies to deler av Trøndelag, Nordland og sør i Troms og Finnmark.
Instructions
Keep away from steep slopes, as well as streams and rivers with high discharge. Keep water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides.
Consequences
Situation that requires vigilance and may cause local damages
On Sunday we expect high avalanche danger for region Helgeland. Avalanche problem is wet snow (slab avalanches) and wind drifted snow (slab avalanches).
Area
Applies to Helgeland.
Instructions
Travelling in avalanche terrain is not recommended. Avalanches may hit avalanche-exposed roads and settlements.
