Avalanche warning for region Jotunheimen Tuesday 27.03.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within 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. • Difficult to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Se snødekke for info

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Difficult to trigger • Possible • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Hard fokksnø oppå kant.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Easy to trigger • Possible • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Liten belastning der det er mykere snø / korte avstands ned til kanten.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Easy to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Et sted mellom liten og stor. Mange steder ligger det under harde fokksnø flak og skal mere til å trigge , enn der det ligger under myke.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 1200 masl • Laget var her overdekket Av et vindskarelag.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 3 - Large • Some steep slopes SE, S, SW • Skredproblemet gjelder for alle himmelretninger, men er mer eller mindre lett å påvirke. Møt øst er det mer fersk fokksnø og der er laget mye mer potent, med drønn og svake stabilitetstester og glatte brudd. Sørvendt i dag finnes de samme to kantkornlagene, men de er ikke like potente.

A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW • Gjekk fra 800 - 1400 moh. Stor tilleggsbelastning der flaket er hardt og liten ved mykere flak lavere i terrenget.

A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Easy to trigger • Possible • 2 - Medium • Some steep slopes NE, E, SE below 0 masl • Har ikke sjekket andre himmelretninger
