Avalanche warning for region Sør-Trøndelag Wednesday 19.01.2022

Danger level 4 - High avalanche danger

Published:
Big wet natural avalanches are expected as long as it's high temperatures. Avoid avalanche release and run out areas. The danger for dry avalanches are expected to increase throughout the day.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on many steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

Wind drifted snow (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).

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

Skredfaren går noe ned utover dagen med minkende vind, avtagende nedbør og synkende temperatur. Men tidlig på dagen kan det fortsatt løsne skred naturlig, både våte flakskred under mildværsgrensa og tørre skred høyere til fjells.

Over mildværsgrensa vil det ha bygget seg opp store, ustabile fokksnøflak i leheng. Disse vil det være lett for en skiløper å løse ut, særlig der flakene er myke og/eller tynne.
