Avalanche warning for region Helgeland Friday 07.04.2023

Danger level 2 - Moderate avalanche danger

Published:
Wet avalanches may release naturally in lower terrain. At higher elevations there can be fresh wind slabs in northeast facing terrian when the wind picks up towards the evening. Persistent weak layers are present deeper in the snowpack, but is in general hard to trigger.

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).

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)

Thursday 6. April 2023

Det har vært milde temperaturer hele denne uken. I lavlandet var det natt til torsdag plussgrader gjennom hele døgnet og snøen er våt. Høyere opp i terrenget er snøoverflaten fuktig i sørvendte brattheng når solen står på, men fryser til skare når det ikke er solinnstråling. I mer nordvent sider eller flatere terreng som er mindre utsatt for solinnstråling er det fortsatt tørr snø.

Dypt i snødekket finnes det svake lag av kantkorn rundt et skarelag. Dette er godt beskyttet av overliggende snødekke og regnes som svært vanskelig å påvirke.

Det meldes om godt skiføre, men at timing er viktig når solen påvirker snøoverflaten.

Mountain weather

Thursday 6. April 2023

Little to no precipitation. Strong breeze from southeast. -7 °C to 0 °C at 1100 m a.s.l. Partly cloudy.

Friday 7. April 2023

2-6 mm precipitation. Rain up to 500 m a.s.l during the afternoon. Fresh breeze from southeast, changing to strong breeze from the southwest during the evening. -6 °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

Mildvær og noe regn gjør at det fortsatt kan løsne våte skred i lavlandet under ca 600 moh. Det ventes hovedsakelig løssnøskred, men enkelte flakskred kan ikke utelukkes.

Kraftig vind gir vindtransport inn i nordøstlig terreng. Det kan være lett å løse ut skred i den ferske fokksnøen.

Det finnes svake lag med kantkorn dypt i snødekket, men det skal generelt svært stor tilleggsbelastning til for å trigge skred på dette laget.
