Avalanche forecast for Salten Wednesday 2019-02-13

3
Considerable
Published:

Demanding conditions, avoid areas with fresh wind deposited snow. It is also possible to trigger a persistant weak layer in the old snow.

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
Spontaneous release
Some 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
Some steep slopes
Possible

Dangersign

Whumpf sound

Område: På dette stedet. Beskrivelse: Svak lyd, men person 30 meter fra utløse punkt følte setningen. Det var tykt snødekke med mye fersk vindtransportert snø hvor drønnet ble utløst. På samme sted ble det fremprovosere skytende sprekker i skavl/leformasjon, men antar at drønnet kom fra lag dypere i snødekket det var lite tegn til propagering i fokksnø og heller ikke sprekkdannelse da drønnet ble utløst. Antatt lag er angitt i profil.
