Avalanche warning for region Salten Sunday 31.03.2019

Danger level 3 - Considerable avalanche danger

Published:
Locally unstable conditions due to wind slabs in lee areas. Persistent weak layers may also be triggered where the snow cover is thin.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Saturday 30. March 2019

Torsdag denne uka kom det inn et skikkelig mildvær med mye regn (over 60 mm) opptil 1000 moh med dels kraftig vind fra vest.

Det er relativt lite snø ute ved kysten. Mer i østlige deler av regionen.

Mellom fokksnøen og skaren fra februar har det utviklet seg et svakt lag av kantkorn mange steder. Laget går lett til brudd og har god bruddforplantningsevne, men ligger stort sett under hard fokksnø nå.

På grunn av manglende observasjoner er det usikker i hvilken grad mildværet har påvirket det svake laget.

Mountain weather

Saturday 30. March 2019

12 mm precipitation, up to 20 mm in the most exposed areas. Moderate gale from west, changing to fresh breeze from the west during the afternoon. -9 °C to -4 °C at 1100 m a.s.l. Cloudy.

Sunday 31. March 2019

8 mm precipitation, up to 15 mm in the most exposed areas. Strong breeze from west. -11 °C to -4 °C at 1100 m a.s.l. Cloudy.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Fortsatt snøvær og kuling fra vest gjør at faregrad 3 - betydelig opprettholdes.

Nedbør som snø de siste dagene danner ustabile flak i østlig sektor og det vil fortsatt kunne gå naturlig utløste skred.

Stor pålagring eller skred i fersk fokksnø kan trigge kantkornlaget dypere i snødekket og dette kan medføre store skred.
