    Considerable danger

Freezing level has reached mountain tops but is refrozen again. New wind slabs will form in SW-W winds on Monday and Tuesday but warming again on Wednesday. A Weak layer might form under the wind slab.

The avalanche bulletin is at a regional scale. It does not necessarily represent avalanche danger in urban areas.

Avalanche problems in the area

A wind slab that will form on Monday and Tuesday in SW-W winds might become unstable if facits will form on the boundary with the wet snow.

The wind slab which is forming in SW-W winds might become unstable in the thawing on Wednesday.

In higher elevations there might be wind slabs which have not had so much thawing. Weak layers below them might fail due to heavy loading.

Snow layers and snow cover

Last week we had windslabs from two snowstorms which got wet at lower elevations. On Sunday it became wet, even on highest mountains but only for few hours. Weak layer might form as it is freezing again with new windslab forming on top in SW-W winds Monday and Tuesday. That weak layer might develope until the thawing again on Wednesday.

Recent avalanches

Many slab avalanches last two weeks in Skagafjordur and Fnjóskadalur, few of them 13-15th of January.
