Avalanche warning for region Svalbard øst Tuesday 03.01.2023

Danger level 4 - High avalanche danger

Published:
Continuous strong wind and snow will lead to an extreme amount of wind transported snow. Avoid all avalanche terrain. Very large naturally triggered avalanches likely.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4). Remote triggering is possible.

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.

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

NB! Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun for faregrad 4 og 5.
Kraftig vind og betydelige nedbørsmengder fortsetter og det ventes ytterligere pålagring av fokksnø i leområder. Det er fremdeles fare for at svært store skred kan løsne av seg selv.
I terreng over ca. 400 moh må vedvarende svake lag i snødekket tas med i betraktning da snøskred kan utløses på avstand.
Skredløp forventes å bli uvanlig lange og det må legges inn ekstra stor sikkerhetsmargin til alt skredterreng.
