Avalanche forecast for Indre Sogn Friday 2019-01-18

3
Considerable
Published:

Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there.

New snow (slab avalanches)

Buried weak layer of new snow

Avoid terrain traps and steep slopes until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
2 - Medium
Low additional load
Many steep slopes
Possible

New snow (loose snow avalanches)

Loose snow

Avoid terrain traps and large steep slopes until the new snow has stabilized. Move gradually away from the fall line when skiing on large slopes to avoid to be caught by small sluffs you released while skiing. The avalanche problem is generally widely distributed on any steep slope with deep new snow.
1 - Small
Spontaneous release
Many steep slopes
Possible
