Avalanche warning for region Romsdal Monday 09.01.2023

Avalanche Problems

• 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 • 2 - Medium • Few steep slopes N, NE, W, NW above 400 masl • Der fokksnøen var P hard og over 15 cm tykk klarte jeg ikke tråkke ut noe som helst eller påvirke lagene under. Der fokksnø flakene var tynnere gikk de lettere: 10-15 cm gikk med stor, under 10 cm gikk med middels . Sprekking bare rundt skia eller 30-40 cm . Fant ikke skarelag overalt, men noen steder løsnet det i nyttårssnøen som rakk å bli kantete nok.

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. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW between 800 masl and 500 masl • Problemet kan nok finnes i alle himmelretninger. Vær mest oppmerksom i skoggrensen og overgang tynne til tykkere flak.

• 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. The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes N, NE, SW, W, NW above 500 masl • Problemet er nok størst i skoggrensen. Kan nok være lett å løse ut små flak og vanskelig å løse ut str 2.

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 1 - Small • Few steep slopes N between unknown masl and unknown masl
