Avalanche forecast for Salten Tuesday 2019-02-05

2
Moderate
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 here.

Wind drifted snow (slab avalanches)

Poor bonding between layers in wind deposited snow

Be careful and keep distance to each other in steep (above 30 degrees) terrain 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.
2 - Medium
High additional load
Specific steep slopes
Possible

New snow (slab avalanches)

Poor bonding between crust and overlying snow

Be careful in steep slopes and around terrain traps 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.

Avalanche Danger Assessment

2 Moderate Stabile forhold generelt på fjellet. Forecast correct Det har vært mye vind de siste dagene og endel vindtransport, men det virker som snødekket er stabilt. Vær likevel oppmerksom i le-heng der ny fokksnø enda trenger litt tid på å stabilisere.

Avalanche Problems

Dry slab avalanche Poor bonding between layers in wind deposited snow Difficult to trigger Possible Specific steep slopes N, W, NW above 400 masl

Avalanche Activity

4. Feb. During the day (+01:00) No avalanche activity

Tests

ECTP30@66cmQ3 Good Stabiliteten i den nye fokksnøen er god.

Snow Cover
