Avalanche warning for region Lofoten og Vesterålen Wednesday 16.01.2019

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • 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. • Easy to trigger • 1 - Small • Some steep slopes E, SE, S, SW above 0 masl • Fokksnøflak. 1F på toppen hvor dette problemet finnes. Begrenset skred str.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 1 - Small • Some steep slopes E, SE, S above 400 masl

• Loose dry avalanche • Loose snow • Difficult to trigger • Unlikely • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • The weak layer collapses easily and clean (easy propagation). • Likely • 2 - Medium • above 0 masl • Vinden i går har flytta veldig mye snø. Lesidene er godt lasta. Store varasjoner og varierende vindretninger

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). • 1 - Small • Few steep slopes above 600 masl • Ved observasjonssted (400 moh) var det god binding mellom fokksnøen og underliggende mildværsskare. Høyere opp (over 600) danner fokksnøen flak og slipper lett mot skaren.
