Avalanche warning for region Hallingdal Tuesday 27.02.2018

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

Avalanche problems

Wind drifted snow (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).

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)

Monday 26. February 2018

Over skoggrensa er det meste av snøoverflaten preget av vind fra ulike retninger. Utsatte terrengformasjoner som rygger er avblåst eller har hard snøoverflate, skjermede områder kan fremdeles ha områder med løs snø. Fra skoggrensa og ned er snøen i hovedsak ubundet. Sola har begynt å påvirke snøen i bratte sørsider.

Det finnes lag av kantkorn/begerkrystaller nede i snødekket.

Ingen skredaktivitet observert siste tre døgn.

Fredag ble det observert ferske sprekker i snøen i Ål.

Mountain weather

Monday 26. February 2018

Little to no precipitation. Breeze from northeast, changing to strong breeze from the east during the evening. -20 °C to -8 °C at 1400 m a.s.l. Partly cloudy.

Tuesday 27. February 2018

No precipitation. Moderate gale from east. -25 °C to -17 °C at 1400 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

Kuling fra øst vil føre til transport av fersk fokksnø til vestvendte leområder. Vedvarende svake lag kan påvirkes på tynt snødekke og ved stor tilleggsbelastning.
