Highlights

Windslabs will gradually stabilize, but are possible to release.

Cornices can crack and release fresh wind slabs underneath. Weak layers of faceted crystals buried under the slabs might be found locally. The weak layers can cause slightly bigger and more reactive wind slabs to trigger.

In steep sun- facing sides, small wet avalanches can occur.

    • Above 200 m

Avalanche Activity

Windslabs will gradually stabilize, but are possible to release. Cornices can crack and release fresh wind slabs underneath. Weak layers of faceted crystals buried under the slabs might be found locally. The weak layers can cause slightly bigger and more reactive wind slabs to trigger. In steep sun- facing sides, small wet avalanches can occur.

Fokksnøflak er for det meste harde etter vinden og vil gradvis stabiliseres.

Toppskavlar er godt utvikla og kan løyse ut skred i terreng under dersom dei knekk.

Enkelte stader kan det være nyare kantkorndanning høgt i snødekket som kan forsterke fokksnøproblemet. Det vil si at flaket både er lettare å løyse ut og at det aukar storleiken.

I bratte solsider kan det lausne små våte skred dersom sola får tak.

Snowpack Structure

Snøoverflata er harde fokksnøflak i leområder for sterk vind. Før siste snøfall var snøoverflata påvirka av mildvêr som gav mykje smeltedanning i den eldre snøen. Etter vêrforhold er det grunn til å tru at det er enkelte lommer av nyere kantkorn høgt i snødekket, under fersk fokksnø.

Tendency

A change in wind direction means that avalanches may release in SW–NE facing slopes that previously were not particularly exposed. The avalanche danger is greatest in areas where faceted crystals exist beneath wind-drifted snow, and in these areas the slab will be easier to trigger. Since the faceted crystals beneath the crust are not highly developed and lie high in the snowpack, the extent of the avalanche problem is limited.

Cornices are well-developed and may trigger avalanches if they break.

In steep, sun-exposed slopes, small wet avalanches may occur.
