Avalanche warning for region Jotunheimen Saturday 13.01.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Easy to trigger • Possible • 1 - Small • N, NE above 1900 masl

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 • Unlikely • 2 - Medium • Few steep slopes N, NE, E • Dette skredproblemet er nok ikke spesielt potent og trolig er det fokksnø flak som er hovedproblemet i regionen. Kan kanskje nevnes i teksten men ikke som et eget skredproblem. Vanskelig å si noe konkret om utbredelsen, men har funnet dette laget tidligere oppå 20.12 skaren. Tydelig kant nå, så det har utviklet seg. Får ikke noen faretegn på dette laget. Fokksnø var ikke skredproblem på runden min i dag, da den er svært hard og bærende over skogen i allehommelretninger i dette området. Den fokksnøen som var hadde stabilisert seg godt uten oppsprekking eller noen tegn på sjikt overganger e.l

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Unlikely • 2 - Medium • Few steep slopes • Løs ubundet snø under lite flak, mest sannsynlig i ferd med å stabilisere seg.

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 • Likely • 1 - Small • Few steep slopes S, SW between 1800 masl and 1400 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, NW above 1500 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, NW above 1500 masl

Avalanche Problems

• Loose snow • Unlikely

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 • 2 - Medium • Some steep slopes N, NE, E, NW above 1000 masl • Varierende overdekning.

Avalanche Problems

• Loose snow • Difficult to trigger
