Avalanche warning for region Nordenskiöld Land Thursday 27.01.2022

Avalanche Problems

• Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • 2 - Medium • Few steep slopes N, NE, E, SE, S above 0 masl • Blåst fra vestlig retning til dels NV derfor er S også med da vinden har blitt styrt til N-lig i de N-S vendte dalene.

• 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 • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Samme skredproblem som tidligere

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes E, SE, S • Terrenget har som vanlig kanalisert vinden. Men hovedretningen var fra NV

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW • Kantkorn i snødekket som er utbredt i alle himmelretninger.

Avalanche Problems

• Dry slab avalanche • Over one meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 2 - Medium • Some steep slopes NW above 0 masl

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). • E, SE

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • Unknown • below 100 masl • Appears to be decomposing facet snow.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 1 - Small • Some steep slopes N, W, NW below 100 masl

Avalanche Problems

• Loose snow • N below 100 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW • På observasjonsstedet var ikke kantkornlaget potent, men antar at det kan være mer likt andre områder rundt Longyearbyen der hvor det ligger noe mer snø enn på observasjonsstedet.

A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Flere kantkornlag nedover i søylen og velutviklet i bunn. De gunstige forhold for oppbygging vi har hatt i vinter gjør at der er kantkorn å finne i søylen og bunnen alle plasser hvor der har vært snø over lengere tid.
