Avalanche forecast for Lofoten og Vesterålen Saturday 2019-03-16

2
Moderate
Published:

Locally unstable conditions. A persistent weak layer of facets is lingering above the February 23 crust layer. Avoid recently loaded areas with wind slabs as these areas can be easy to trigger.

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow above a crust

Keep distance to each other when traveling in avelanche terrain. NB, remote triggering is possible. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience. Danger signs are whoumpf-sounds and cracking which means that you influence weak layers and should avoid avalanche terrain. However, absence of signs does not mean it is safe.
3 - Large
Low additional load
Isolated steep slopes

ECTX Good

Avalanche Danger Assessment

1 Low Snødekket har stabilisert seg ytterligere. Stabilitetstest ga ingen utslag, og testheng viste ingen forplantningsevne. Fortsatt ikke kantkorn observert.Snøen som falt i natt og på formiddagen bidrar ikke i særlig grad til å endre dette. Mildere vær vil kunne påvirke snødekket i leformasjoner og sørvendte heng. Forecast too high Varslet faregrad er for høy i Vesterålen.

Avalanche Activity
