Avalanche warning for region Heiane Thursday 30.04.2020

Danger level 2 - Moderate avalanche danger

Published:
Keep distance to areas with glide cracks at lower elevations. Wind slabs are a problem at high elevations.

Avalanche problems

Glide avalanches

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

Wet snow/melting near the ground

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Buried weak layer of new snow

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)

Wednesday 29. April 2020

Det er generelt fremdeles store snømengder i fjellet og store skavler på topprygger. Det solrike været de siste ukene har smelta om det gamle snødekket fra finkorna til grovkorna i solvendte sider. I skyggevendte sider i høyden er det gamle snødekket fremdeles delvis finkorna og lagdelt. Sigesprekker er synlige i enkelte områder. Det er etter hvert stor forskjell på snøgrensa i regionen, med lavere snøgrense i indre og skyggevendte områder.

Det er ikke observert vedvarende svake lag av betydning.

Onsdag formiddag er det på Blåsjø målestasjon (1105 moh) -2 grader og 8 m/s fra Ø.

Thursday 30. April 2020

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 sørøst og nysnø vil danne fokksnøflak i leområder i høyfjellet.
Det gamle snødekket, altså der snøoverflaten er hard, vurderes som stabilt.
Sigesprekker i snødekket er et tydelig forvarsel på glideskred.
