Avalanche forecast for Salten Sunday 2019-03-10

2
Moderate
Published:

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

Wind drifted snow (slab avalanches)

Buried weak layer of new snow

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.
2 - Medium
Low additional load
Specific steep slopes
Possible

New snow (loose snow avalanches)

Loose snow

Be careful near terrain traps and in large steep slopes until the new snow has stabilized. Move gradually away from the fall line when skiing on large slopes to avoid to be caught by small sluffs you released while skiing. The avalanche problem is generally widely distributed on any steep slope with deep new snow.
1 - Small
Low additional load
Widespread steep slopes
Possible

Image Of Danger Sign
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.

Weather

Snow Cover

82 cm in total Elevation of new snow 0 masl. Snow line at 0 masl Much loose snow (10-30cm) Dry Under tregrensa er snøen ubunden, og flere steder kun løssnø som dekker bar bakke. I tregrensa og opp mot toppen på ca 470moh var underlaget under nysnøen flere steder merkbart påvirket av vinden de siste dagene. Og det hadde dannet seg fokksnø, samt små skavler i østvendte sider.

Tests

CTH27@28cmQ3 Testen ble tatt i 20 graders helling

Snow Profile

6 stratigraphy layers observed 1 Tests connected to snow profile Snøprofilen er tatt på en fjelltur i slakt terreng og er ikke representativ for hva vi finner ellers i fjellet der vinden har påvirket snødekket de siste dagene og dannet nysnøflak. I laget under ishinnen mener jeg at det var både kantkorn og begerkrystaller men arrester meg gjerne om det er feil (se vedlagte bilder) Tok en CT og fikk CTH27@28cm Q3, så ut som det var nedføyket nysnø, se eget bilde
