Avalanche warning for region Tromsø Friday 15.03.2024

Danger level 2 - Moderate avalanche danger

Published:
A little fresh snow with some wind gives unstable windslabs. Mostly small but bigger where the most snow comes. Be careful in lee aereas where the snow may rest on facets on the surface. Avalanches could be very easy to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Thursday 14. March 2024

Opp til ca 3-400 moh er snødekket for det meste smelteomvandlet. I fjellet er det hovedsakelig hard fokksnø, sastrugi eller skare på overflaten, men mykere snø kan finnes i enkelte formasjoner som er skjermet for vind.

Det finnes vedvarende svakt lag av kantkorn rundt et skarelag som ble dannet i slutten av januar. Mildvær og regn gikk da opp til ca 1000 moh.
Kantkornene har nå blitt mer avrundet etter en periode med mildt vær, så det antas at det nå er lite sannsynlig å løse ut store skred.

Mountain weather

Thursday 14. March 2024

Little to no precipitation. Fresh breeze from southeast, changing to breeze from the northwest during the afternoon. -11 °C to -3 °C at 700 m a.s.l. Cloudy.

Friday 15. March 2024

3 mm precipitation, up to 8 mm in the most exposed areas. Precipitation as snow. Strong breeze from north, changing to fresh breeze from the southwest during the afternoon. -16 °C to -4 °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

Litt nedbør og en del vind danner nysnøflak. Flakene blir stort sett små men der det legger seg mest kan det bli størrelse 2. Enkelte steder finnes kantkorn og rim i overflaten. Dersom dette snør ned kan det bli ekstra lett å løse ut skred. Mest utsatt er formasjoner der snøen er bundet i myke flak.
