Avalanche warning for region Lyngen Saturday 31.03.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 3 - Large • Most steep slopes N, NE, E, SE, S, SW, W, NW between 800 masl and 100 masl • Bryter lett, men ikke glatt. Noen steder går det til bunns, andre slipper det under gammelt skarelag.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Possible • 2 - Medium • Many steep slopes N, NE, E between 1000 masl and 400 masl • Fokksnøflakene varierer litt, men mye er nå pennhardt.

• 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. • Difficult to trigger • Unlikely • 2 - Medium • Some steep slopes N, NE, E between 500 masl and 200 masl • Der vinden ikke har tatt så hardt er overflaten myk, og ligger over ubunden løs snø.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • Likely • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW • Etter lang tid med skiftende vindretning og mye nedbør vil det fortsatt være vanskelig å ha full oversikt over utbredelsen på dette skredproblemet.

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. • Easy to trigger • Likely • 2 - Medium • Some steep slopes N, NE, E between 900 masl and 400 masl • Der fokksnøen begynner å hardne til. Mange lokale vindretninger, les kart og terrengformasjoner.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 3 - Large • Most steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 100 masl • Observert naturlige skred som går mot bakken fra parkeringsplss på Varto 100moh, videre opp i skogen. Dårlig sikt, men ihvertfall godt over tregrensa.
