Avalanche warning for region Trollheimen Friday 14.05.2021
Danger level 2 - Moderate avalanche danger
Published:
Be careful on steep slopes with soft and wet snow, a skier can trigger avalanches here, or they can release when the temperature increases. Persistent weak layers buried in the old snowpack can cause natural released avalanches. Keep good distance to avalanche terrain and run out zones for wet avalanches.
Avalanche problems
Wet snow (loose snow avalanches)
on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).
Persistent weak layer (slab avalanches)
on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.
Glide avalanches
on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).
Advice
Snow cover (in Norwegian)
Høye temperaturer og mangel på nattefrost har fuktet fokksnøen i høyfjellet, men lagdeling kan fortsatt å være intakt. Mot sør og i lavereliggende terreng er hele snødekket smelteomdannet. Snøgrensen kryper oppover og ligger nå på rundt 300-700 moh. Lavest i nordvendt terreng.
I det gamle snødekket ligger noen steder vedvarende svake lag som nå gradvis kan bli aktive når varme og vann trenger ned i snødekket.
Det er observert mange små våte løssnøskred i alle himmelretninger.
