Avalanche warning for region Sør-Troms Friday 24.02.2023

Danger level 2 - Moderate avalanche danger

Published:
New unstable wind slabs will form because of wind and snowfall. Avoid steep slopes with newly formed wind slabs. Old persistent weak layers can be triggered where the snowpack is thin.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new 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)

Thursday 23. February 2023

Forrige uke fuktet et kraftig mildvær snødekket høyt til fjells. Dette frøs senere til og dannet et hardt skarelag. Over dette kan det etter kraftig vind og litt nysnø på torsdag ligge en del fokksnø i leområder. På vindutsatte steder er det avblåst ned til skarelag eller bakken.

I naboregionene er det observert rimkrystaller og kantkorn nært overflaten. Kaldt og klart vær mandag til onsdag gjør at det ikke kan utelukes at disse lagene finnes også i Sør-Troms.

Mountain weather

Thursday 23. February 2023

10 mm precipitation, up to 22 mm in the most exposed areas. Rain up to 200 m a.s.l during the afternoon. Moderate gale from south, changing to breeze from the southwest during the afternoon. -6 °C to -1 °C at 700 m a.s.l. Cloudy.

Friday 24. February 2023

8 mm precipitation, up to 15 mm in the most exposed areas. Precipitation as snow. Breeze from west. -9 °C to -3 °C at 700 m a.s.l. Partly 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

Vind og nysnø vil danne ferske flak med ustabil fokksnø i leområder. Vær oppmerksom på at fokksnøen enkelte steder kan ha lagt seg over svake lag med rimkystaller eller kantkorn. Det er usikkert om dette har skjedd, men hvis det er tilfelle vil flakene være mer ustabile enn ellers.
