Avalanche forecast for Nord-Troms Monday 2019-04-22

2
Moderate
Published:

Lokalt ustabile forhold pga fokksnø høyt til fjells. Om kvelden vil stigende temperatur og regn gi økende fare og mulighet for naturlig utløst skred.

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
Low additional load
Isolated steep slopes
Possible

Wet snow (loose snow avalanches)

Loose snow

Be careful in avalanche release and runout areas. Avoid skiing in terrain traps. Timing is important. Stability decreases when the snow surface gets wet and soft. Wet snow avalanches tend to release spontaneously.
1 - Small
Low additional load
Specific steep slopes
Possible

Wet snow (slab avalanches)

Buried weak layer of faceted snow above a crust

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
High additional load
Isolated steep slopes
Unlikely
