Avalanche warning for region Nord-Trøndelag Tuesday 18.01.2022

Danger level 4 - High avalanche danger

Published:
Very dangerous avalanche conditions. Travel in avalanche terrain not recommended. We expect intense wet slab activity around and below treeline. Wind slabs can be easily triggered in the alpine.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on many steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Mountain weather

Tuesday 18. January 2022

25 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 1200 m a.s.l during the afternoon. Strong breeze from southwest, changing to gale from the southwest during renoon. -7 °C to 1 °C at 1100 m a.s.l. Cloudy.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Skredfaren ventes å øke i takt med stigende temperaturer og nedbør som regn utover dagen. Når regnet trenger ned til sjiktovergang i fokksnø og svake lag dypere i snødekket vil det går store naturlige utløste skred. Hold god avstand fra alt skredterreng.

Før mildværet kommer, vil skiftende vindretning gi stor pålagring av fokksnø i leområder fra skoggrensen og oppover. Dette gir økt fare for naturlig utløste tørre flakskred.

Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun i forbindelse med faregrad 4 og 5.
