Avalanche forecast for Nord-Troms Tuesday 2019-02-26

Highest danger level per day:
2
Moderate
Published:

Locally unstable conditions due to wind slabs in lee areas. At higher elevations, persistent weak layers may also be triggered where the snow cover is thin.

Illustrasjon av ferdselsråd 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.
Illustrasjon av ferdselsråd Avoid staying for a longer period in 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.

Wind drifted snow (slab avalanches)
