Avalanche forecast for Finnmarkskysten Saturday 2021-01-16

Highest danger level per day:
2
Moderate
Published:

Avoid avalanche terrain with newly deposited wind slabs. The wind slabs are overlying a persistent weak layer, and avalanches can therefor be easier to trigger and get bigger than if persistent weak layers were absent.

Illustrasjon av ferdselsråd Avoid terrain steeper than 30 degrees and runout zones where the avalanche problem is present. Remote triggering is possible.
Illustrasjon av ferdselsråd NB: Identifying the avalanche problem is very difficult.
Illustrasjon av ferdselsråd Avoid terrain traps.

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow beneath a crust

Avalanche Danger Assessment

Det er meldt mildvær fra fredag, men det er usikkert om det påvirker kantkornlaget fra 3-400m og oppover

Snow Cover

No snowdrift Storm slab (soft slab) Dry 20cm fokksnø i forsenkninger og bak rygger. 5cm på plasser hvor det er flatt. Ellers avblåst ned til bakken, spesielt i sydlig eksposisjon. Det observeres ett tydelig kantkornlag under skare, generelt i fjellet over 300moh. Krystallene har fasetter, men klarte ikke å observere stepp eller 120 grader. Laget var heller ikke så luftig, men svært sprøtt
