Avalanche warning for region Lyngen Sunday 13.12.2020

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 • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW between 800 masl and 400 masl • Ikke aktuelt før det evt snør ned.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • 1 - Small • Few steep slopes above 800 masl • Generelt stabilt snødekke, men var noen tynne fokksnøflak 5-10cm tykke, øverst i snøpakken, i bratthenget opp mot toppen som løsnet lett. Dårlig propagering og ganske små flak.

Avalanche Problems

• Tilgjengelig løssnø for vindtransport fra enkelte skål og renne formasjoner.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW between 500 masl and 100 masl • Ikke aktuelt enda, da bare et tynt skarelag i overflaten løsner.

• 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. The overlying slab is soft. • Difficult to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW between 500 masl and 100 masl • Kk over gammel skarepakke med 4F fokksnø over.

Avalanche Problems

• Poor bonding between layers in wind deposited snow • N, NE, E, SE, S, SW, W, NW above 700 masl • vanskelig p løse ut skred nå. Likevel, Vær obs for bratte formasjoner som har samlet fersk fokksnø, spesielt høyt til fjellet og i daler med kaldere temperaturer der det stabiliserer saktere
