Avalanche warning for region Svalbard øst Sunday 15.01.2023

Danger level 4 - High avalanche danger

Published:
Heavy snowfall and an increase in wind will lead to a large amount of wind transported snow. Avoid all avalanche terrain. Naturally triggered avalanches likely.
  • The danger is greatest until Sunday afternoon

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)

Avalanches may release spontaneously 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.

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.
Mye nysnø og svært kraftig vind vil danne store fokksnøflak i leheng som kan løsne naturlig når været står på.
I terreng over ca. 300 moh må vedvarende svake lag i snødekket tas med i betraktning. Skredløp forventes å bli uvanlig lange og det må legges inn ekstra stor sikkerhetsmargin til alt skredterreng.

Vind og nedbør ventes å minke fra søndag ettermiddag.
