Avalanche forecast for Salten Monday 2019-02-11

3
Considerable
Published:

Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. A persistent weak layer can be present underneath fresh wind deposited snow in isolated features.

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
Widespread steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow beneath a crust

Avoid skiing in avalanche terrain (steep terrain more than 30 degrees and in runout zones). NB, remote triggering is likely. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience. Danger signs are whoumpf-sounds, cracking and recent avalanches. However, absence of signs does not mean it is safe.
3 - Large
High additional load
Specific steep slopes
Possible
