Avalanche forecast for Nord-Troms Saturday 2019-02-02

2
Moderate
Published:

Use caution on slopes recently loaded with wind slabs. Large avalanches is not very likely but can in some cases be triggered by high additional loads. 

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.

Avalanche Problems

Dry slab avalanche Poor bonding between layers in wind deposited snow Within half a meter The weak layer collapses easily and clean (easy propagation). Difficult to trigger 2 - Medium W, NW above 400 masl

Avalanche Danger Assessment

2 Moderate Generell stabile forhold. i Isolerte brattheng i le for siste dagers SØ vind kan det fortsatt være fokksnøflak som det kan løses ut skred i ved stor tilleggsbelastning. Skredfaren vurderes til en 2-moderat Værutsikter tilsier ingen endringer i skredfaren de kommende dagene

Snow Cover

100 cm in total No snowdrift Wind slab (hard slab) Dry Ikke løssnø tilgjengelig for vindtransport. Vindparker hardt over konveks og vindparker fokksnø dom sprekker opp rundt for i leområder. Gammel skarelag over rygger i høyden. Dannet seg små overflaterim i skogen, men ikke observert over tregrensa.
