Avalanche warning for region Lyngen Saturday 20.03.2021

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 many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Persistent weak layer (slab avalanches)

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

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.

Snow cover (in Norwegian)

I slutten av februar var det relativt mildt og snøoverflaten ble fuktig opp til ca. 500 moh. Etter dette har det kommet påfyll med snø. Noen steder ligger denne ubunden i terrenget, mens over skoggrensen har det enkelte steder dannet seg fokksnøflak av varierende hardhet.

I høyden finnes er det observert begynnende kantkorndannelse i overgangen mellom gammel smelteomvandlet snø og nysnø. Under ca. 500 moh. er det gamle snødekket gjennomfuktet etter mildværet i slutten av februar, men over dette finnes det fortsatt enkelte kantkornlag i det gamle snødekket.

Fredag har det blitt automatisk detektert naturlig utløste skred i både i Holmbuktura og fra Pollfjellet
