Avalanche forecast for Vest-Telemark Tuesday 2019-03-12

3
Considerable
Published:

Avoid terrain traps and big steep slopes. Wait until the fresh snow has stabilized.

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
Spontaneous release
Widespread steep slopes
Possible
