Avalanche forecast for Vest-Finnmark Tuesday 2019-05-14

Highest danger level per day:
2
Moderate
Published:

Be aware of isolated wind slabs, otherwise stable conditions.

Illustrasjon av ferdselsråd Be careful and keep distance to each other in steep (above 30 degrees) terrain with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.

Avalanche Danger Assessment

2 Moderate Regnbyger i dag opp til 600 moh gir vått snødekke og det er mulig å løse ut små til middels store våte løssnøskred i bratt terreng. Høyt i fjellet kan ferske fokksnøflak lett løses ut, og gi skred str 1-2. Faregrad 2 Vind fra V vil flytte på noe snø på de høyeste toppene og platåene, og gi noen ferske fokksnøflak. Overskyet og regn natt til i morgen onsdag gir lite frysing av snødekket, og plussgrader opp til 600-700 moh gir mulighet for å løse ut våte løssnøskred. Forecast correct

Avalanche Activity

14. May. During the day No avalanche activity Observert fra E6 Alta - Langfjordbotn: Dårlig sikt på toppene. Ingen skredaktivitet fra i dag opp til 600 moh. Mulig 1-2 skred str 2 fra i går, men kan være gamle.
