Avalanche warning for region Lyngen Saturday 01.04.2023

Danger level 4 - High avalanche danger

Published:
Large avalanches are very easy to trigger, even remotely from flatter terrain. Avoid travel in or near avalanche terrain with fresh snow from the last few days. The snowpack just got a heavy load, and needs time to adjust. The sun might also release a few natural avalanches in steep, south facing terrain.

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches 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)

Saturday 1. April 2023

Før været kom inn har det vært svekkelse av snøoverflaten i det klare, kalde været. 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.

Fredag morgen har det kommet 20-40cm nysnø i regionen, og det har blåst stiv kuling til storm i fjellet.

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 avtar, og i takt med det avtar også risikoen for naturlig utløste skred. Det vil være svært lett å løse ut skred i den ferske snøen fra de siste dagene, og skred kan bli store til svært store. Fjernutløsing forventes, unngå ferdsel og opphold i eller nært skredterreng der det ligger fersk snø.

Dersom sola tar kan enkelte store skred løsne naturlig i lun, sørvendt terreng. Mindre naturlig utløste løssnøskred kan også løse ut store flakskred i den ferske snøen.
