Avalanche warning for region Helgeland Tuesday 30.04.2024

Danger level 2 - Moderate avalanche danger

Published:
Rising temperature increases the risk of wet avalanches in all aspects. Loose avlanches are most likely, but a few slab avalanches may occur. Stay away from cornices and glide cracks.

In the alpine there may be unstable wind deposited snow in north facing terrain. The slabs may rest on facets near the surface.

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).

Loose snow

Wind drifted 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)

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.

Snow cover (in Norwegian)

Monday 29. April 2024

I sørvendt terreng har snøoverflaten over flere dager blitt varmet opp av sola og fryst til om natta. I lavlandet under ca 600-700 meter over havet er snødekket smelteomvandlet og uten lagdeling av betydning.

I nordvendt terreng er det mer vinterlige forhold med tørr snø. I naboregionen Svartisen er det observert fasettering i overflaten.

Stedvis finnes det vedvarende svakt lag ved bakken i høyfjellet, men det ligger godt beskyttet under bærende skarelag.

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

Stigende temperatur kan gi våte skred i alle himmelretninger. Det ventes flest løssnøskred, men enkelte flakskred kan ikke utelukkes. Sannsynligheten for skavlbrudd og glideskred øker også med mildværet.

I nordvendt terreng kan fokksnø hvile på svakt lag av kantkorn. Her kan det være lett å løse ut små skred, særlig hvis mildværet myker opp overliggende flak.
