Avalanche warning for region Tromsø Sunday 26.01.2020

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Few steep slopes SE, S, SW, W above 400 masl • LB ved lett klapping. Ikke glatt bruddflate @10cm. Den fjellside er sterkt preget av vinden og det er kun noen meget begrensete lommer med nedføyket nysnø. I fjellsider som var mer beskyttet fra gårdagens vind vil jeg anta at dette skredproblemet er mer utbredt og kanskje også at størrelse på skredet kan være middels. Ref observerte eldre naturlig utløste skred.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Many steep slopes SE, S, SW, W above 300 masl

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 • 3 - Large • Many steep slopes N, NE above 400 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Many steep slopes N, NE, E, SE, NW above 300 masl • Har stort sett gått i lo/kryssladet terreng idag. Mulig str. 2 mer utbredt i le.

• 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. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, NW above unknown masl • Antar vi legger på "lett til vanskelig" og "str 2 til 3" idag. Det ligger stedvis mye snø som ikke er hardt vindpåvirket, tenker derfor at evt skred vil kunne gi en del medrivning nedover.

• 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 • Some steep slopes N, NE, E, W, NW above 300 masl
