Avalanche warning for region Sør-Troms Friday 20.03.2020

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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Some steep slopes E, SE, S above 200 masl • Opplever skredproblem i skogen og oppover. I fleste leheng ligger det ferske fokkflak som er svært lett å løse ut. Forventer flere slvutløste skred størrelse 2.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within 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 • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl • Har kun sett dette opp til 450moh, men finner det under mildværskaren fra siste mildvær i alle aspekt

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW above 500 masl

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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Some steep slopes E, SE, S, SW, W above 400 masl • Lettbunden snø (F) over et svakt lag av nedføyket nysnø. Denne situasjonen endres kraftig fra kl 14:00 da vinden tiltok og vi opplevde moderat til kraftig snøfokk.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes E, SE, S, SW, W not between 500 masl and 300 masl • Finner dette laget i og rett over tregrensa, men IKKE oppe på 500 i dag - S leside. Vanskelig å løse ut der hvor vi var i dag, men her er det store variasjoner i regioneen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S above 600 masl
