Avalanche forecast for Vest-Finnmark Wednesday 2019-02-13

2
Moderate
Published:

Locally unstable avalanche conditions. Be cautious in steep terrain, storm slabs can be triggered. There may be some areas with a weak layer of facets.

Wind drifted snow (slab avalanches)

Buried weak layer of new snow

Be careful and keep distance to each other in steep (above 30 degrees) terrain with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.

Tur til tverrfjellet. Myk fokksnø ca F på solid vindskare de fleste plasser. Vinden har flyttet snøen fra noen ryggformasjoner, men det var ikke noe reaktiv flakdanning som vi kunde se.
