Avalanche warning for region Trollheimen Thursday 07.02.2019

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, E, W, NW above 500 masl • Skredproblemet kan finnes i alle himmelretninger pga lokale vindretningsvariasjoner, mer er mest fremtredende i angitt sektor.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Few steep slopes SW not between 1000 masl and 600 masl • Flanke mot SV på heng som i hovedsak vender Sør, noe ubunden snø og myk fokksnø mot SV, avtagende dybde og økende hardhet mot sør. Mye avblåst terreng i området, kun enkeltheng med innblåst snø.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Difficult to trigger • N, NE, S, SW, W, NW • Flere skarelag ned mot bakken med kantkorn under det øvre skarelaget mot fokksnøen og tidvis observert kantkorn mot bakken også i sørlig sektor i enkelte heng med tynt snødekke.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • Many steep slopes N, NE, E between unknown masl and 800 masl

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Some steep slopes NW between unknown masl and 1000 masl
