Avalanche warning for region Lyngen Friday 31.03.2023

Danger level 4 - High avalanche danger

Published:
Large natural avalanches are expected. Avoid travel in or near avalanche terrain. Avalanches might impact infrastructure such as roads. Large amounts of snow and wind will overload a weak snowpack. It is uncertain where the weather will be most severe.

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on many steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4). 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)

Friday 31. March 2023

Det har vært svekkelse av snøoverflaten i det klare, kalde været i det siste. I sør forventes det kantkorndanning i forbindelse tynn solskare.

Rundt mildværsskare fra begynnelsen av mars finnes det lag med kantkorn. Generelt viser tester at det har begrenset evne til bruddforplantning, og det er ikke observert faretegn eller skredaktivitet i tilknytning til dette laget i det siste.

Natt til torsdag begynte snøværet, og det har frem til torsdag morgen kommet 5-10cm nysnø i regionen. Liten til stiv kuling fra nord har allerede begynt å flytte inn snø i leformasjoner.

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

Nedbør og vind fortsetter å gi stor pålagring på et svakt snødekke. Store til svært store skred ventes å løsne naturlig. Disse kan nå langt ut i flatere terreng og påvirke infrastruktur og bebyggelse. Snøen kommer på en uvanlig vindretning, og skred kan løsne i sjeldne eller helt nye skredbaner.

Det er usikkert nøyaktig hvor nedbøren treffer, og dersom det kommer mindre nedbør er skredfaren lavere.
