Avalanche forecast for Salten Monday 2019-03-11

2
Moderate
Published:

Be careful in terrain with fresh wind-deposited snow. Also be careful in steep and sunexposed terrain.

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.
Illustrasjon av ferdselsråd Be careful in avalanche release and runout areas. Avoid skiing in terrain traps. Timing is important. Stability decreases when the snow surface gets wet and soft. Wet snow avalanches tend to release spontaneously.

Image 1 of 3 Of:  Danger Sign Copyright:  Lene Comment:  I det jeg kjørte over en liten kant som lå i le av dagens vindretning fra NØ sprakk det opp i snøen. Jeg dro ut nysnøflak med 4F/1F hardhet på 20 cm tykkelse. Dette lå på et tynt skarelag. Flere lag med smeltepakke og skarelag under når jeg graver med hendene. A Antar at det er dårlig binding til sksrelaget/nedføyket nysnø som gjør at det løsner.
