Avalanche warning for region Indre Troms Sunday 15.05.2022

Danger level 2 - Moderate avalanche danger

Published:

Wet avalanches can release in steep terrain where dry snow becomes wet and loose. At higher elevations, where it is colder, the snowpack is more dry and some small wind slabs can occur and old persistent weak layer can still be present.

Avalanche problems

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

New snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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.

Snow cover (in Norwegian)

Regn og stigende temperaturer den siste uka har gjort snøoverflaten våt og fuktig oppover i fjellet. I fjellet kan det ligge tørrere flak av fokksnø etter perioder med snø og vind de siste dagene. Snødekket virker å være isotermt opp til ca 800 moh.

Rundt skare fra 23. april har det vært temperaturgradient og utviklet seg kantkorn. Det har kommet mye snø de siste ukene, og laget ligger mange steder dypt. Laget er derfor generelt vanskelig å påvirke. I snøprofiler ved Altevann søndag var kantkorn fuktig og nedbrutt på ca. 600 moh, men fortsatt tørt og inntakt på snøprofil på ca. 1000 moh.
