Avalanche warning for region Sunnmøre Tuesday 21.02.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S above 700 masl • Delvis funnet dette skredproblemet, men sterkt avtagende. Da bindingene innad i fokksnøen fra helgen har stabilisert seg. De mest eksponerte konveksene i høyden har sannsynligvis problemet enda.

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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E above 600 masl

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. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, W, NW above 800 masl • Hvis min teori om att det er fuktig snö som sen hatt en oppbyggande process så kan det vara sån at det bare har varit i en begrenset höjd intervall. Dvs snön kommit torrare högre opp och då inte samme fukt eller temp gradient när det blitt kaldere efter.. I varslet nysnö som svakt lag blir mer representativt .

• Loose wet avalanche • Spontaneous release • 3 - Large • E, SE, S, SW above 400 masl • Stor sol meldt imorra formiddag med mye ny lössnö.

• Wet slab avalanche • Spontaneous release • 3 - Large • Some steep slopes SE, S, SW above unknown masl • Sol instråling formiddag
