Avalanche warning for region Ofoten Tuesday 11.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies, especially where the wind deposited slabs are thin or soft. A slab avalanche is easier to trigger there.

Avalanche problems

Wind drifted snow (slab avalanches)

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

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)

Monday 10. February 2020

I høyden består snødekket i stor grad av vindpakket fokksnø av varierende hardhet og skavler. Noen steder er finnes avblåst gammel eller barmark.

Under mildværgrensen har lavere temperaturer medført at snøoverflaten har frosset til.

Gammelt snødekke består i stor grad av ulike skarelag og smelteomvandlet snø.

Forrige uke ble det observert tydelige kantkorn under fokksnøen, men dette viste i flere stabilitetstester ingen evne til bruddforplantning. I nærheten av gammelt skarelag er det også observert kantkorn.

Mandag er det skredaktivitet ved Rombaksrennene i Narvik. Det er snakk om løssnøskred

Mildværet fredag nådde i ytre strøk opp til rundt 1000 moh.

Avalanche risk assessment

Betydelige mengder nedbør og vind gir skredproblem med ferske fokksnøflak i leområder. Fokksnøflakene trenger tid tid stabilisering og det er mulig for skiløper å løse ut slike flak.
