Avalanche warning for region Jotunheimen Wednesday 18.12.2019

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 overlying slab is soft. • Very easy to trigger • 1 - Small • Few steep slopes NE, E, SE, S above 1000 masl • Små flak løsner svært lett i enkelte heng som pålagres mest. Samtidig er det ikke veldig mye løs snø tilgjengelig for transport i fjellet vest for Tyin - derfor blir både skredproblemutbredelsen og den potensielle stølrrelsen begrenset. Har IKKE vurdert andre himmelretninger enn østvendt ved Tyin.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE above 2500 masl • Ingen drønn på dette laget i dag, Is/ skarelag over som trolig gjør laget vanskkelig å påvirke der det er tykkere snødekke. Generelt begrensede flak fremdeles som vil kunne begrense skredstørrelsen. Mye løsere kant over også, så laget virker ikke spesielt potent.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, SW, W, NW above unknown masl
