Avalanche warning for region Helgeland Sunday 05.02.2023

Danger level 3 - Considerable avalanche danger

Published:
Generally unstable conditions. Natural avalanches can occur and you have to expect to trigger avalanches when venturing into steeper terrain.

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

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)

Saturday 4. February 2023

Det har vært rolig vær og ingen nedbør av betydning de siste dagene. Siste større snøfall kom i starten av uken. I høyden preges snøoverflaten av vind mange steder, med fokksnø av ulik hardhet. I formasjoner som er skjermet for vind ligger det en god del løs snø på overflaten.

Det har utviklet seg et lag av kantkorn høyt i snødekke. Det har også dannet seg rim på overflaten etter kaldt og klart vær.

Mountain weather

Saturday 4. February 2023

5 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 200 m a.s.l during the evening. Strong breeze from south, changing to moderate gale from the south during the evening. -22 °C to -8 °C at 1100 m a.s.l. Partly cloudy.

Sunday 5. February 2023

15 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 400 m a.s.l Sunday night. Strong breeze from south, changing to fresh breeze from the west during the afternoon. -8 °C to -3 °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

Faren for naturlig utløste skred ventes å øke. Kraftig vind i kombinasjon med opp mot 25 cm nysnø vil danne store flak i leformasjoner. Flakene legger seg på et allerede ustabilt snødekke og skredene kan bli store. En person må regne med å løse ut skred i bratt terreng.
