Avalanche Danger Assessment

2 Moderate Nedføyket overflaterim (SH) utgjør et skredproblem i enkeltsider i høyfjellet. Mindre skred kan potensielt trigge et kantkornproblem lenger ned i snøen, som ellers vil være svært vanskelig for en skiløper å påvirke. Da vil skredene også kunne bli større. Overflaterim, nedføyket overflaterim og kantkorn kan gi vedvarende skredproblem dersom temperaturene holder seg lave. Forecast correct

Danger Sign

No signs observed

Weather

No precipitation -11.3 °C 10 m/s from S ↑ Skyfritt. Kraftig vind på toppen (15 m/s) men betydelig roligere lenger ned, rundt gravepunkt.

Snow Cover

Surface hoar on a hard surface Dry Kraftig vind (15 m/s) i høyden ga snøfokk, til tross for lite snø tilgjengelig for vindtransport. Ellers ingen fokk. Snødekket består i hovedsak av skare med kantkorn under og ulike stadier av overflaterim oppå.

Tests

ECTPV@10cmQ2 Poor Bryter ved frigjøring i nedføyket kantkorn.
