Avalanche warning for region Tromsø Thursday 03.02.2022

Danger level 2 - Moderate avalanche danger

Published:
It is possible to trigger avalanches in wind slabs since stabilizing takes time in the cold weather. It is also favorable conditions to develop facet crystals around crust high in the snowpack, which can become an avalanche problem. Deeper persistent layers exist, but are very hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger 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)

Wednesday 2. February 2022

Laurdag var det sterk vind frå søraust som påverka snøen som kom i veka. Snøoverflata vekslar mellom ubunden snø, fokksnø av varierande hardheit og skare, alt etter kvar vinden har tatt.

Det er gunstige tilhøve for oppbyggande forvandling av snøkrystallar høgt i snødekket. Kantkorn har stadvis starta å utvikle seg rundt mildvêrskara, danna for ca. ei veke sidan. Det finnast også eldre kantkornlag djupare i snødekket, men desse er godt beskytta og vanskelege å påverke.

Tysdag var det observert eit skred under skavlen på Gråtind.

Mountain weather

Thursday 3. February 2022

No precipitation. Fresh breeze from southeast, changing to strong breeze from the southeast during the evening. -22 °C to -8 °C at 700 m a.s.l. Partly 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

Enkelte stadar kan det vere mogleg å løyse ut skred i fersk fokksnø, særleg om kvelden når vinden blir sterkare .Det er også gunstige tilhøve for danning av kantkornlag rundt skare, like under fokksnøflaka, som kan bli eit nytt skredproblem. Det finnast vedvarande svake lag djupare i snødekket, men dei fleste stadane er desse godt beskytta av hard overliggande snø, og svært vanskelege å påverke.
