Published:

The danger is considerable with high winds and heavy precipitation. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies.

Snow cover (in Norwegian)

Det har kommet endel snø den siste uken, i kombinasjon med vind. Over skoggrensen har det dannet seg fokksnøflak av varierende hardhet, mens det i skjermede formasjoner kan finnes ubunden snø. Tirsdag er det mildt, så snøen ventes å være fuktig opp til skoggrensen.

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

Søndag kveld og mandag morgen er det automatisk detektert flere skred i både Lavangsdalen og fra Pollfjellet.

Tirsdag er det mildvær og par plussgrader i Lyngen
