Avalanche forecast for Indre Troms Saturday 2019-03-16

2
Moderate
Published:

Be careful in terrain where you find fresh wind deposited snow. Weak layers beneath the new snow can be triggered by a skier.

New snow (slab avalanches)

Buried weak layer of new snow

Be careful in steep slopes and around terrain traps 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.
2 - Medium
Low additional load
Specific steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow above a crust

Keep distance to each other when traveling in avelanche terrain. NB, remote triggering is possible. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience. Danger signs are whoumpf-sounds and cracking which means that you influence weak layers and should avoid avalanche terrain. However, absence of signs does not mean it is safe.
