Avalanche forecast for Sør-Troms Wednesday 2019-02-27

2
Moderate
Published:

Be careful in areas with fresh wind deposited snow in the alpine. The snow is soaked at lower elevations and can lead to small wet avalanches.

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.
2 - Medium
Spontaneous release
Specific steep slopes
Possible

Wind drifted snow (slab avalanches)

Buried weak layer of new 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.

Low additional load
