Avalanche warning for region Heiane Thursday 16.03.2023

Danger level 4 - High avalanche danger

Published:
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 from Thursday afternoon

Avalanche problems

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).

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 car or destroy a small house (size 3). 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.

Snow cover (in Norwegian)

Wednesday 15. March 2023

Det ligger nysnø på snøoverflaten etter snøfall mandag. I fjellet har det stedvis vært kraftig vind og det er vekslende avblåst og isete og fokksnøflak av varierende hardhet.

Det er observert kantkorn over skarelag som var lett å løse ut før mandagens mildvær kom inn. Det er uklart hvor mye som har blitt igjen av dette.

Det gikk flere skred over FV 450 Hunnedalsvegen mandag kveld.

Mountain weather

Wednesday 15. March 2023

3 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 200 m a.s.l during renoon. Breeze from north. -11 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Thursday 16. March 2023

21 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 300 m a.s.l during the afternoon. Strong breeze from southeast, changing to strong gale from the southeast during the afternoon. -16 °C to -5 °C at 1100 m a.s.l. 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

Svært kraftig vind og mye nysnø fra torsdag ettermiddag gir økende skredfare og krevende forhold i regionen.

Det vil samle seg mye fokksnø i leområder og store skred kan løsne av seg selv. Mest utsatt terreng er fjellsider mot nordvest, men vedvarende svakt lag kan fortsatt være aktivt og gi skred i alle himmelretninger.

Unngå alt skredterreng. Skred i kjente skredbaner kan få lange utløp.
