Timeline
- Tuesday, 18 January 07:00 - ongoing danger
- Wednesday, 19 January 13:00 - danger is over
Landslides may be expected. Exposed railways and roads may be closed. Heavy rain is expected. Relatively high temperatures and windy conditions causes significant snowmelting. The expected rain will increase the danger of landslides, especially where groundwater and soil moisture are already high. Risk of slushflows is especially high in areas with more than 50 cm snow. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows.
Area
Applies to deler av Trøndelag, Nordland og 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.
On Wednesday we expect considerable avalanche danger for region Sør-Troms. Avalanche problem is wet snow (slab avalanches) and wind drifted snow (slab avalanches).
Area
Applies to Sør-Troms.
Instructions
Travelling in avalanche terrain requires advanced knowledge, experience in route finding and ability to identify the avalanche problem. Generally, it is recommended to avoid avalanche terrain. Avalanches may hit some avalanche-exposed roads and occasionally settlements.
