Avalanche forecast for Indre Sogn Thursday 2019-02-14

3
Considerable
Published:

Precipitation as rain leads to higher avalanche danger. A weak layer deep in the snow pack can now become more active. Avoid fresh stormslabs above the new snow line.

Wet snow (slab avalanches)

Water pooling in/above snow layers

Avoid avalanche release and run out areas. Wet snow avalanches tend to release spontaneously. Stability decreases when the snow surface gets wet and soft. Timing is important.
3 - Large
Spontaneous release
Many steep slopes
Possible

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.
3 - Large
Low additional load
Many steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow near surface

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
Low additional load
Some steep slopes
Possible

Snødekke er påvirket av mildvær / regn. Trolig har det hoppet seg opp vann over hardere lag i snødekke. Bekker har begynt å åpne seg, trolig har det samles seg mindre dammer på myrer, forskjekninger i terrenget. Se fesk bilder av Dalavatnet, 400moh.
