Avalanche forecast for Sunnmøre Wednesday 2019-05-15

Highest danger level per day:
2
Moderate
Published:

When the sun comes out, the danger will rise in areas where the snow becomes wet and soft. Be aware when crossing run out zones below steep mountain sides. Size 2 natural released avalanches are possible.

Illustrasjon av ferdselsråd 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.
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.
