Avalanche forecast for Salten Tuesday 2019-03-26

3
Considerable
Published:

The snowpack is unstable. Avoid areas with wind-deposited snow. It is also possible that wind slab avalanches trigger avalanches in a persistant weak layer in the old snow!

Wind drifted snow (slab avalanches)

Buried weak layer of new snow

Avoid steep (more than 30 degrees) areas with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.
3 - Large
Low additional load
Specific steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow above 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.

Avalanche Activity

25. Mar. During the day Dry slab avalanche One (1). Spontaneous release NE. Between 500 masl and 200 masl Vanskelig å si om skredet har gått ila av det siste døgnet pga avstanden. Var ikke langt nok inne på fjellet til å kunne se hvor det hadde stanset men tror det nederste eg kunne se var ca på 250moh

Weather

No precipitation -3 °C 4 m/s from SE ↖ 90% clouds Mye løs ubunden snø i fjellet. På toooen av Harlifjellet lå det 15cm nysnø på toopen av gammel isskare. I skogen var det opptil 40 cm løssnø.
