Avalanche warning for region Sunnmøre Tuesday 25.02.2020

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. • Easy to trigger • 2 - Medium • Some steep slopes N, SW, W, NW above 600 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Few steep slopes NE, E, SE, S above 600 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 700 masl • Tynn skare som eg mistenker kan vere mildværskare frå helga ein gang. Svært usikkert problem, bør vere en del av varselet trur eg. Lite utvikla kant.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE above 1000 masl

• Loose dry avalanche • Loose snow • Easy to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl

Avalanche Problems

• Loose dry avalanche • Loose snow • Easy to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl • LBT viste utslag på ca 40 cm i PP/DF hardhet F

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • 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. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 600 masl • Tror at det på mer utsatte plasser kan være tett med skredstr. 3. Med all snøen som har kommet de siste dagene.

• 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. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes E, SE, S above 800 masl • Myke snø flak har gått naturlig. Stabiliserer seg raskt. Ikke et eget betydelig skredproblem.
