Avalanche forecast for Svartisen Friday 2019-03-22

3
Considerable
Published:

Demanding conditions. A persistent weak layer is buried in the snowpack. The avalanche danger increases when the rain sets in. Avoid potential release areas and runout areas for avalanches. At higher altitudes avoid areas with wind-deposited snow, typically behind ridges, ribs and in gullies.

Wet snow (slab avalanches)

Buried weak layer of faceted snow above a crust

Avoid 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.
3 - Large
Spontaneous release
Specific steep slopes
Possible

New snow (slab avalanches)

Buried weak layer of new snow

Avoid terrain traps and steep slopes until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
3 - Large
Low additional load
Specific steep slopes
Possible
