Avalanche warning for region Lyngen Sunday 17.02.2019

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 • Possible • 1 - Small • Few steep slopes N, NE, E above 0 masl • Der våt snø har rukket å fryse, og vindtransport har funnet sted.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • Possible • 1 - Small • N, NE, E between unknown masl and 500 masl • Der det er kommet mer nysnø, og vind enda ikke har tatt i.

• 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 • Possible • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 600 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Easy to trigger • Possible • 2 - Medium • N, NE, E, SE, S, SW, W, NW above 0 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 1 - Small • Some steep slopes N, NE, E above 600 masl • På høyfjellet der det er kommet tørrsnø og vind.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 500 masl • Stor sett nøytralisert av regn og mildvær opp til ca 500moh. Uvisst hvor høyt det går.

• Wet slab avalanche • Water pooling in/above snow layers • Within half a meter • The overlying slab is soft. • Easy to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S, SW, W, NW below 500 masl • Den mest akutte endringen er over, og vil nøytraliseres av drenering og nattefrost.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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. • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 600 masl • Ser ut til at mildværet har hatt effekt i hvertfall opp til 700 moh noen steder. Avhengig av hvor langt ned varmen har kommet i snødekket vil det terrenget under stabiliseres.
