Avalanche warning for region Heiane Friday 03.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh windloaded snow. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

Wet snow (slab avalanches)

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

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 2. January 2020

Kraftig vind, mye nedbør og høye temperaturer de siste dagene preger snødekket. Vestlig vind har tidligere lagt opp mye snø i leområder mot Ø. Under 1000 moh har det vært stor snøsmelting og det er generelt lite snø i regionen, spesielt i vestlige deler.

Mountain weather

Thursday 2. January 2020

5 mm precipitation, up to 17 mm in the most exposed areas. Fresh breeze from west, changing to strong breeze from the southwest during the afternoon. -2 °C to 1 °C at 1100 m a.s.l. Partly cloudy.

Friday 3. January 2020

20 mm precipitation, up to 40 mm in the most exposed areas. Gale from west. -6 °C to 2 °C at 1100 m a.s.l. Partly 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 kraftig vind og mye nedbør med synkende snøgrense vil gi stor snøtransport over 6-800 moh.
I leheng over mildværsgrensen vil det legge seg fokksnøflak som kan være ustabile. Flak kan noen steder legge seg over hard skare som kan utgjøre et godt glilag.

I enkelte heng i høyden som får stor pålagring vil skred kunne løsne naturlig.

Under mildværsgrensen vil regn i snø kunne gi våte skred, spesielt mot hardt og glatt underlag.

Skredfaren er høyest i nordre og indre del av regionen som vil få mest nedbør som snø.
