Avalanche warning for region Helgeland Tuesday 19.12.2023

Danger level 3 - Considerable avalanche danger

Published:
Strong winds and snowfall at higher elevations. Naturally triggered avalanches likely. Avoid all avalanche 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.

Buried weak layer of surface hoar

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

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 18. December 2023

Snødekket er generelt tynt i lavereliggende områder etter mye regn de siste dagen.

I høyere områder kom nedbøren som snø. Mest i indre deler der det kom 40-80 cm lørdag til mandag. Det har dannet seg tykke fokksnøflak i leformasjoner grunnet kraftig vind fra hovedsakelig vestlige retninger. Vi antar at svake lag av kantkorn og rim fremdeles er intakte. Det finnes svake lag både ved bakken og høyere opp i snødekket.

Mountain weather

Monday 18. December 2023

30 mm precipitation, up to 45 mm in the most exposed areas. Rain up to 700 m a.s.l during renoon. Moderate gale from west. -4 °C to 0 °C at 1100 m a.s.l. Cloudy.

Tuesday 19. December 2023

20 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 400 m a.s.l Tuesday night. Strong gale from west, changing to fresh breeze from the west during the evening. -8 °C to -3 °C at 1100 m a.s.l.

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

Det har vært mye snø og kraftig vind i høyden siden lørdag og været fortsetter på sammen måte. Det ventes naturlig utløste skred i høyden, der flakene ligger på et ustabilt snødekke. Man må forvente muligheten for å kunne utløse snøskred i bratt terreng.

I lavereliggende område er faren for spontant utløste våte skred avtagende, men fortsatt til stedet.
