Avalanche warning for region Jotunheimen Saturday 29.04.2023

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). • Difficult to trigger • 2 - Medium • Det er flere svake lag høyt i snødekket, men laget over er mykt og har liten forplantningsevne. Vil trolig bli et større problem med været som er meldt inn. Ikke undersøkt nedre utbredelse og har hatt fokus på øst-vendte heng.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes E, SE, S, SW, W above 1500 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes E, SE between 1400 masl and 1100 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 1 - Small • Few steep slopes N, NE, NW above 900 masl • gikk bare I nordvendt i dag fra ca 1000moh. en del nysnø fra de siste dagene som var lett vindpåvirket. ganske jevnt fordelt som ga veldig god skiføre. der vinden fikk litt mer tak fant vi myke flak som var lett å påvirke. under flakene fant vi stort sett nedføyket nysnø som var litt kantete. delvis -også i profilen - fant vi ganske godt utviklet kantkorn men fikk ECTX. tenker at flaket er for myk eller for å forplante et brudd. tenker derfor vanskelig-få-str1 på den turen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, NW between 1500 masl and 1000 masl • Kan være mulig å løse ut i områder der snødekket er tynt.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, SE, S, SW, NW above 1000 masl • Funnet i nordvendte heng mellom 1000 og 1500 moh og sørvendte heng mellom 1600 og 2200 moh.
