Avalanche forecast for Nord-Troms Tuesday 2021-05-11

Highest danger level per day:
2
Moderate
Published:

Be careful on steep slopes with soft and wet snow, a skier can trigger avalanches here, or they can release when the temperature increases. At high altitudes, a persistent layer of facets are buried in the snowpack in isolated areas.

Illustrasjon av ferdselsråd Wet surface: Move gradually away from the fall line when skiing on large slopes to avoid to be caught by small sluffs you or someone else in your group release while skiing.
Illustrasjon av ferdselsråd Dry surface: Avoid terrain steeper than 30 degrees and runout zones where the avalanche problem is present. Remote triggering is possible.
Illustrasjon av ferdselsråd Dry surface: NB: Identifying the avalanche problem is very difficult.
Illustrasjon av ferdselsråd Avoid terrain traps.

Danger Sign

No signs observed

Snow Cover

No snowdrift 5 cm new snow Some loose snow (1-10cm) Dry Vær nysnø opp til 800 m. Noe pålagring av Fokksnøflak i høyden medvind fra nord. Indre strøk av regionen fikk ikke mye snø 1. mai helgen og dermed ikke like utbredt kantkornproblematikk

Weather

No precipitation 1 °C from N ↓ 80% clouds

Avalanche Problems

Dry slab avalanche Buried weak layer of faceted snow above a crust Within half a meter The collapsing weak layer is thin < 3 cm. Difficult to trigger 3 - Large N, NE, E, SE, S, SW, W, NW

Dry slab avalanche Buried weak layer of new snow Within half a meter The collapsing weak layer is thin < 3 cm. The overlying slab is soft. Easy to trigger SE, S, SW above 800 masl

Avalanche Danger Assessment

2 Moderate Usikkerhet hvor stor utbredelse kantkornlaget har, og det ligger godt beskyttet under ei hard snøpakke. Fersk snø i høyden og litt pålagring i leområder for nordlig vind kan lett løses ut mindre skred i. Værprognoser tilsier ikke stor endring i skredfaren Forecast too high
