Avalanche Problems

Dry slab avalanche Poor bonding between layers in wind deposited snow Within half a meter Difficult to trigger Unlikely 2 - Medium Not given N, NE, E, SE, S, SW, W, NW between 1500 masl and 1300 masl Generelt flere skiktdelinger i denne høyden, hvor nedbør skifter mellom tørt og vått.

Wet slab avalanche Buried weak layer of faceted snow beneath a crust Within a meter Very difficult to trigger Unlikely 3 - Large Widespread steep slopes N, NE, E, SE, S, SW, W, NW above 1200 masl Neppe skiløperpåvirkbart

Weather

No precipitation 0 °C 17 m/s from SW ↗ 100% clouds Vindkuler øverst på grensen til farlige.

Tests

ECTX Good Alt kompakt over gammel isskare/ Kantkorn under omvandling som kommer Q3 på 90cm med stump vold.

CTH20@15cmQ1 Medium P/K smelt frys under og over. Smelteomvandlet, men ikke umulig at det har vært et rimlag. 1400 m Ø

Avalanche Danger Assessment

2 Moderate Snøen i de fleste høyder er vanskelig å påvirke som skiløper. 13-1500 m skiller seg ut med mer skiktdeling. Kantkornlag omvandles sakte men sikkert. Forecast correct

Snow Cover

370 cm in total No snowdrift Snow line at 350 masl. Layered snow begins at 1000 masl Moist Kompakt vårsnø til over 1000 m. Etterhvert skarelag og noen ganske tydelige lagdelinger rundt 13-1400 m særlig skikt 15 cm nede mellom to smelt/frys lag (CTH). Gamle Kantkornlag under isskare er i denne høyden godt igang med smelteomvandling. Høyere oppe på 1650 er det halvtørr snø under skarelag øverst, og noen veldig sterke smelt/frys soner 20-40 cm. All snø over gammel isskare/kantkornlag (90 cm) oppfører seg som kompakt blokk. Kantkorn er i begynnende omvandling og krever svært stor tilleggslast (utenfor ET-skala). Minimal temperaturgradient (-1 til -2). Kun observert 1 skred som begynte som flakskred (1100 m). Ellers noen få våte løssnøskred synlig.
