Avalanche forecast for Voss Tuesday 2019-03-26

3
Considerable
Published:

Above the new snow line the danger will increase in lee areas. Wet loose avalanches are the biggest problem below new snow line, the danger increases in the afternoon, when the rain sets in.

Wet snow (loose snow avalanches)

Loose snow

Avoid avalanche release and run out areas. Wet snow avalanches tend to release spontaneously. Timing is important. Stability decreases when the snow surface gets wet and soft.
2 - Medium
Spontaneous release
Widespread steep slopes
Possible

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.
2 - Medium
Low additional load
Specific steep slopes
Possible
