Avalanche warning for region Ofoten Tuesday 23.03.2021

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies. Wet avalanches are likely at lower altitudes in the morning.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

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 22. March 2021

I lavere områder er snødekket preget at skiftende vær den siste tiden.

I fjellet har til tider kraftig vind lagt opp fokksnøflak av varierende hardhet i leområder. For øvrig består snødekket over tregrensen av eldre fokksnøflak, skarelag og enkelte kantkornlag

I fjellet, særlig indre strøk finnes det vedvarende svake lag av kantkorn dypt i snødekket. De ligger generelt under harde lag av fokksnø og er vanskelig å påvirke. Enkelte steder i fjellet er det også observert begynnende kantkorn høyere i snødekket, men det virker ikke å være et utbredt og potent skredproblem per nå.

Mountain weather

Monday 22. March 2021

5 mm precipitation, up to 10 mm in the most exposed areas. Breeze from west, changing to strong breeze from the southwest during the evening. -11 °C to -2 °C at 1100 m a.s.l. Cloudy.

Tuesday 23. March 2021

12 mm precipitation, up to 25 mm in the most exposed areas. Moderate gale from southwest, changing to fresh breeze from the southwest during the evening. -5 °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

Tidlig på dagen vil det fremdeles være mulig at det løsner et og annet naturlig utløst vått skred, men ettersom temperaturen synker avtar sannsynligheten for våte skred (inntil temperaturen stiger brått mot midnatt).

Over mildværsgrensen vil svært kraftig vind og snø bygge opp ustabile fokksnøflak i leområder. I de delene av regionen der det kommer mest nedbør kan det være lett for en skikjører å løse ut middels store skred i fokksnøen.

Vedvarende svake lag av kantkorn er stort sett vanskelig å påvirke.
