Avalanche warning for region Indre Troms Monday 12.02.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • A big and identifiable crystal in the weak layer. • Easy to trigger • Unlikely • 2 - Medium • Few steep slopes N between 600 masl and 500 masl • Wery local, smaller steep hills.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • Unlikely • 2 - Medium • Few steep slopes N between 500 masl and 0 masl • Fant ett nedføyket nysnølag mellom to lag med avrundet korn, dette laget har røket tidligere (over en uke siden) I samme heng. Det løsnet lett men propagerte ikke på ect. Flakene er meget lokale og generelt små.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, NW between 500 masl and 400 masl

Avalanche Problems

• Dry slab avalanche • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Unlikely • 1 - Small • Few steep slopes W above 0 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • Unlikely • 1 - Small • Few steep slopes N, NE, E, SE, S, SW, W, NW between 1500 masl and 400 masl • Skredproblemet her er begynnende omvandling av fokksnø til kantkorn under et skarelag. Dette ligger høyt i snødekket. Men det er ikke utviklet nok til å kollapse eller forplante brudd.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • Unlikely • 1 - Small • Few steep slopes N, NE, NW between 1500 masl and 400 masl • I enkelte leheng har det samlet seg fokksnø som kan ha dårlig binding. En bør være spesielt obs på større dyner med løsere fokksnø i konvekse partier.

Avalanche Problems

• Poor bonding between crust and overlying snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • NE between unknown masl and 0 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). A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 1 - Small • N, NE, NW between unknown masl and 0 masl • Få isolerte heng grunnet svært ihjelblåst snødekke i fjellet

• Dry slab avalanche • Buried weak layer of faceted snow near surface • 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 • Possible • 2 - Medium • Few steep slopes N, NW between unknown masl and 0 masl • Svært tynt lag med ca 1 mm krystaller (påbegynt oppbygging) mellom to lag med smelteformer!

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Unlikely • 1 - Small • Few steep slopes N, W, NW above 400 masl • Det kom 2-4 cm snø på tirsdag denne uka og det blåste kuling fra SØ på torsdag. Dette har ført til at dette skredproblemet er å finne i enkelte spesielt utsatte heng.
