Avalanche forecast for Vest-Finnmark Monday 2019-02-11

2
Moderate
Published:

Strong wind during sunday may have built up some storm slabs. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. There may be some areas with a weak layer of facets.

Wind drifted snow (slab avalanches)

Poor bonding between layers in wind deposited 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.
