Avalanche forecast for Romsdal Monday 2019-02-11

3
Considerable
Published:

The wind increases to NW moderate gale. The wind comes together with 12-25 mm precipitation as snow showers. There are weak persistent weak layers of faceted crystals in the snow cover. The avalanche hazard increases and the likelihood of natural released avalanches is highest during or right after the storm.

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
Spontaneous release
Some steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow near surface

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.
3 - Large
Low additional load
Isolated steep slopes
Possible
