Avalanche warning for region Tromsø Wednesday 13.01.2021

Danger level 1 - Low avalanche danger

Published:
Not much snow below 400 masl. Generally stable conditions, but be careful in areas with windslabs in the alpine. A weak layer of facets can be present below a thin crust. Keep in mind that even small avalanches can have consequences if you fall into rocky terrain.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1) Remote triggering is possible.

Buried weak layer of faceted snow beneath a crust

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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)

Tuesday 12. January 2021

Det er generelt lite snø og ikke skiføre under 300-400 moh. I starten av forrige uke var det plussgrader og litt regn opp til ca 700 moh, så her er overflaten is eller skare. Høyere til fjells finnes stedvis litt fokksnø over skaren.

Under skarelaget har det flere steder dannet seg et velutviklet lag av kantkorn, observasjoner fra helgen tyder på at det enkelte steder kan ha god forplantningsevne.

Søndag ble det observert et lite skred og skytende sprekker i fersk fokksnø, ca 700 moh på Ringvassøya.

Rapportert mer snø på Ringvassøya enn ved Tromsø.

Mountain weather

Tuesday 12. January 2021

No precipitation. Fresh breeze from southeast. -17 °C to -7 °C at 700 m a.s.l. Clear skies.

Wednesday 13. January 2021

No precipitation. Breeze from southeast. -17 °C to -6 °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

Generelt stabile forhold uten påfyll av mer snø. Men enkelte steder i høyden er det mulig å løse ut små fokksnøflak, særlig der denne ligger på et svakt lag av kantkorn.
