Avalanche warning for region Nord-Troms Monday 23.01.2023

Danger level 3 - Considerable avalanche danger

Published:
The danger increases due to strong winds and snow. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies. Near the ground there are a weak layer of faceted snow. This is in general hard to trigger, but avalanches can get big.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

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 beneath a crust

Wet snow (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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 22. January 2023

Søndagens mildvær har sannsyligvis fuktet snødekket høyt til fjells. Før dette besto snødekket over tregrensa stort sett av hardpakket fokksnø med flekker av mykere fokksnø. I skogen var snøen stort sett ubunden.

Det finnes vedvarende svake lag av kantkorn nær bakken fra november, men etter kraftig vind den siste tiden så ligger de stort sett under hard fokksnø.

Det er også registrert begynnende kantkorn høyere i snødekket, men det virker ikke veldig potent, og utbredelse er usikker.

Mountain weather

Sunday 22. January 2023

2-6 mm precipitation. Rain up to 1000 m a.s.l Sunday night. Moderate gale from south. -6 °C to 1 °C at 1100 m a.s.l. Cloudy.

Monday 23. January 2023

8-10 mm precipitation. Rain up to 300 m a.s.l Monday night. Moderate gale from south, changing to gale from the southwest during the afternoon. -9 °C to -2 °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

Mandag vil synkende temperaturer, nedbør og kraftig vind føre til dannelse av ferske fokksnøflak, og noen skred kan løsne naturlig. Der kantkornet ved bakken ikke takler den økte belastningen kan skred bli store, men dette er høyst usikkert, da kantkornet tidligere har vært vanskelig å påvirke.

I lavlandet under mildværsgrensa kan det gå enkelte våte løssnøskred.
