Avalanche warning for region Helgeland Tuesday 31.03.2020

Danger level 4 - High avalanche danger

Published:
It is a complex snowpack with several avalanche problems. Large avalanches can go naturally in wind slabs and in wet snow. Avalanches in persistent weak layer cannot be ruled out. Avoid avalanche terrain.

Avalanche problems

Wind drifted snow (slab avalanches)

on many 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)

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

Water pooling in/above snow layers

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.

Mountain weather

Tuesday 31. March 2020

25 mm precipitation, up to 45 mm in the most exposed areas. Moderate gale from southwest, changing to gale from the west during renoon. -6 °C to -2 °C at 1100 m a.s.l. 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

Store nedbørsmengder, sterk vind og mildare vær vil gi samansette forhold med fleire skredproblem. Over mildværsgrensa vil det danne seg fokksnøflak i leområder i mange himmelretningar grunna dreiande vind. Under mildværsgrensa kan det gå våte flak- og laussnøskred der det kjem regn på snødekket. Det er ukjent om det finnast vedvarande svake lag i snødekket i denne regionen, men det finnast i naboregionen Svartisen. Det kan difor ikkje utelukkast at det finnast også i denne regionen og at vekta av nysnø kan påverke eventuelle slike lag. Det forventast store naturleg utløyste skred. Varselet er basert på eit enklare datagrunnlag enn regionale varsel og utgis kun for faregrad 4 og 5.
