Avalanche warning for region Helgeland Monday 29.04.2024

Danger level 2 - Moderate avalanche danger

Published:
In the alpine there may be some areas with unstable wind deposited snow. The slabs may rest on facets near the surface. Lower in the terrain up to 800 metres above sea level, wet loose snow avalanches may release naturally.

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 can get large enough to bury or even kill you (size 2).

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)

Sunday 28. 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.

Mountain weather

Sunday 28. April 2024

Little to no precipitation. Breeze from southeast, changing to fresh breeze from the southeast during the evening. -5 °C to 0 °C at 1100 m a.s.l. Partly cloudy.

Monday 29. April 2024

8-12 mm precipitation. Rain up to 800 m a.s.l during the afternoon. Moderate gale from southeast. -4 °C to 0 °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

Kraftig vind opp til kuling styrke gir transport av snø inn i terreng mot nordvest. I naboregionen Svartisen er det tidligere observert kantkorn i overflaten. Det kan ikke utelukkes at det også finnes her. Dersom fokksnøen legger seg over kantkorn blir flakene ekstra ustabile. Unngå derfor steder med fersk fokksnø.

I lavlandet kan regn gi løssnøskred under mildværsgrensen på 600 moh.
