Avalanche warning for region Sør-Troms Monday 11.12.2017

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • Difficult to trigger • Possible • 2 - Medium • Some steep slopes above 500 masl • Mye av snøen er blåst bort! Er ikke og finne. Andre steder er det tykt vindpakket snø! Typisk er ved rygger/kuler at man kan klare og påvirke det svake laget, det glir lett når det løsner, sjekker problemet videre ila uken, og hvor høyt det er og finne!

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 • Possible • 2 - Medium • Some steep slopes NE, E, SE above 400 masl • Finnes i noen le-heng der vinden har deponert snø over nysnø

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl • Fant dette ved bakken hele veien, utbredelsen er nok stor.
