Avalanche forecast for Lofoten og Vesterålen Monday 2019-02-11

3
Considerable
Published:

The avalanche danger will increase in areas that gets great amount of new snow combined with strong winds. Avoid areas with fresh wind deposited snow. A weak layer of buried surface hoar can be present underneath fresh wind deposited snow. However, this is not confirmed.

New snow (slab avalanches)

Buried weak layer of new snow

Avoid terrain traps and steep slopes until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
3 - Large
Spontaneous release

Avalanche Danger Assessment

3 Considerable Heftig situasjon. Stor snøtransport. Snøen er fra tidligere tørr og lett, mye av den - så her går det unna. Faren for naturlig utløste skred er knyttet til vinden og vil avta om vinden roer seg.

Avalanche Problems

Dry slab avalanche Buried weak layer of new snow Within half a meter The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. Spontaneous release Likely 3 - Large Not given N, NE, E, SE, S, SW, W, NW Fokksnø pga kraftig vind.
