Avalanche warning for region Hallingdal Tuesday 11.04.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. Use caution in areas with recently formed storm slabs. Its time to switch to spring mode and remember to use slightly different approaches on wet and dry snow.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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)

Monday 10. April 2023

Mandag kom det 10-20 mm nedbør i regionen og kraftig vind om ettermiddagen. I høyden har det dannet seg ferske fokksnøflak i leformasjoner.
Under 600-800 moh er snøen nå fuktig etter regnværet.

Det er flere kantkornlag i snødekket. Disse ligger stort sett under hard skare og er vanskelig å påvirke.

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

Det fortsetter med nedbør også tirsdag. I fjellet der nedbøren kommer som snø kan det raskt legge seg opp fokksnøflak som vil være lette å løse ut. Større flak ventes i nord- og vestvendt terreng, men mindre flak kan også løses ut i andre himmelretninger.

I lavlandet vil alle himmelretninger bli utsatt for våte løssnøskred der det regner. Det er likevel ventet at heng der snøen ikke er smelteomdannet av sola tidligere, vil være mest ustabile.
