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.
Weather forecast
SW-W strong winds on Monday and Tuesday with snowfall but warming again on Wednesday with strong S winds.
