Avalanche warning for region Helgeland Thursday 02.01.2020

Danger level 4 - High avalanche danger

Published:
There will be windslabs and high avalanche danger in the alpine areas. Natural releas of avalanches are expected. In the lower areas the avalanche danger is decreasing.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

Poor bonding between layers in wind deposited snow

Wet snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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.

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

Varselet er basert på eit enklare datagrunnlag enn i ordinære varslingsregionar.

I høgfjellet vil store nedbørsmengder i form av snø kombinert med vind føre til at det vert svært stor pålagring av fokksnø i leområder. Skred kan løysne av seg sjølv. Under nysnøgrensa vil regnvær gjere at det framleis kan gå naturleg utløyste skred der det regnar på snøen, men skredaktiviteten forventast å avta her.
