Avalanche warning for region Indre Troms Monday 23.01.2023

Danger level 3 - Considerable avalanche danger

Published:
Difficult conditions with a lot of wind and precipitation. Natural released avalanches can occur, bothwhere the snow is wet, and in the alpine. Avoid avalanche release and run out areas. There is also a weak layer deep in the snow pack that is generally hard to trigger, but can cause large avalanches if it collapses.

Avalanche problems

Wet snow (slab avalanches)

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

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously 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)

Sunday 22. January 2023

Søndag har mildværet sannsynligvis fuktet snødekket høyt til fjells. Over skoggrensa var det før siste snøfall mye hardt og avblåst. Under skoggrensen var det stort sett løs snø. Rundt skoggrensa var det dannet mykere flak.

Det finnes observasjoner av et kantkornlag rundt et skarelag høyt i snødekket, men utbredelsen og hvor lett det er å påvirke er uviss.
Fra desember/november finnes det vedvarende svake kantkornlag ved bakken og dypt i snødekket.

Mountain weather

Sunday 22. January 2023

5 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 900 m a.s.l Sunday night. Strong breeze from south. -6 °C to 1 °C at 1100 m a.s.l. Cloudy.

Monday 23. January 2023

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 500 m a.s.l Monday night. Moderate gale from southwest, changing to gale from the southwest during the afternoon. -8 °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

Mandag blir det mye vind og en god del bygenedbør. Under mildværsgrensa vil det fortsatt kunne gå naturlig utløste våte skred, men timingen på en slik skredsyklus er høyst usikker. Dersom nedbør og mildvær er nok til å svekke vedvarende svake lag ved bakken eller dypt i snødekket, kan enkelte skred bli store. Men mandagens nedbør og mildvær er sannsynligvis ikke nok til å trigge dette.

Over mildværsgrensa vil det sannsynligvis være såpass stor pålagring av snø i den kraftige vinden at naturlig utløste middels store skred i fersk fokksnø kan forekomme.
