Avalanche warning for region Tromsø Thursday 30.12.2021

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, W, NW above 300 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl • Der overliggende snødekke er tynt er dette laget fult mulig å trigge. Det vil da kunne bli store skred. Der snødekket er tykt anser jeg dette som vanskelig å trigge. Men fortsatt mulig at det kan gå til brudd!!!!

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes S, SW, W above 300 masl • Fokksnøen etter jula virker stabil og vanskelig å påvirke der jeg har vært i dag. Fikk ingen faretegn fra snødekket.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Kantkornlaget under skare er absolutt til stede, men det virker nå svært vanskelig å påvirke dette. Både den overliggende fokksnøen og skarelaget i seg selv er mange steder svært kompakt. Men om man klarer det, kan det gå store skred.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, W, NW above 400 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Fortsatt potent kantkorn.
