Avalanche warning for region Finnmarkskysten Friday 19.03.2021

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with wind deposited snow at high elevations. Increasing temperature will weaken the snow cover temporarily.
There is also weak snow layer deep in the snow in inner parts of the region. It is unlikely for a skier to trigger these layers, but if it happens avalanches will be large.

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

Wet snow (slab avalanches)

on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Water pooling in/above snow layers

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Thursday 18. March 2021

Det er kommet en god del nysnø de siste dagene kombinert med vind fra vest og nord. Mange steder er snøen dermed vindpåvirket, eller det er avblåst til eldre skarelag. Ute ved kysten var det generelt lite snø i terrenget før siste snøfall.

Det finnes vedvarende svake lag av kantkorn i forbindelse med skarelag, og begerkrystaller langs bakken. Dette er trolig mest utbredt i indre strøk. Under ca. 200 moh. er det gamle snødekket gjennomfuktet etter mildværet i slutten av februar.

Mountain weather

Thursday 18. March 2021

1-5 mm precipitation. Strong breeze from northeast, changing to breeze from the southeast during the afternoon. -14 °C to -9 °C at 700 m a.s.l. Partly cloudy.

Friday 19. March 2021

2-4 mm precipitation. Moderate gale from south, changing to strong gale from the south during renoon. -15 °C to -2 °C at 700 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

Kraftig vind fra ny retning fører til at det dannes ferske fokksnøflak i nye leheng. På de stedene som får størst pålagring kan middels store skred løsne naturlig, særlig om kvelden når det forbigående blir mildvær.

Vedvarende svake lag er mest utbredt i indre strøk hvor det er mulig å løse ut store skred på disse hvis terrenget tillater det. De svake lagene ligger dypt i snødekket. Det gjør at de er vanskelige å påvirke, men vær forsiktig i overgangen mellom tynt og tykt snødekke.
