Avalanche warning for region Jotunheimen Monday 26.03.2018

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.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • 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 • Many steep slopes N, NE, E, SE, S, SW, W, NW • Gikk fra ca. 800 moh.

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.

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. 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

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 • Fokksnø på kant, trolig finnes i alle himmelretninger. ( selv om jeg ikke har vært i alle) Definerte le heng. Stor belastning der snøen er hard, eller det er et stykke ned til kantlaget. Liten på mykere snø og eller kortere avstand ned. Kan nok fjern utløse på dette, med det mindre sannsynlig.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Spontaneous release • Possible • 2 - Medium • Some steep slopes N, NE, E, NW above 900 masl • Fersk innblåst snø.
