Avalanche warning for region Nordenskiöld Land Sunday 04.04.2021

Danger level 3 - Considerable avalanche danger

Published:
The danger is increasing. Strong winds and heavy snowdrift could overload the already weak snowpack. Large avalanches are likely, even some very large avalanches. Cornices are likely to collapse and could trigger avalanches on underlying slopes. Avoid all avalanche terrain and run-out zones.

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near surface

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near the ground

Wind drifted snow (slab avalanches)

on some 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)

Saturday 3. April 2021

Snøoverflaten er generelt vindpreget og det er stor variasjon i snømengde. På vindutsatte områder er det avblåst ned til gammel skare eller til bakken.

Det ligger flere aktive vedvarende svake lag av kantkorn i snødekket, også høyt i snødekket under siste ukes fokksnø.

Ved bakken finnes begerkrystaller.

Observasjoner på tydelige drønn og flere store skred siste uken viser at vedvarende svake lag har meget god forplantningsevne.

Onsdag ettermiddag er skredaktivitet ifb med skavlbrekk.

Siste uken har det vært betydelig skredaktivitet i forbindelse med de vedvarende svake lag. Skredene har for det meste vært av str. 3.

Det er skavledannelse langs toppene ned mot Longyearbyen.

Mountain weather

Saturday 3. April 2021

No precipitation. Partly cloudy.

Sunday 4. April 2021

No precipitation. 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

Skredfaren ventes å øke i takt med at vinden tar seg opp.

Det vil trolig bli kraftig pålagring på et allerede ustabilt snødekke. Store naturlige skred ventes, kanskje svært store skred i enkelte heng.

Skavler kan knekke og løse skred i underliggende heng.
