Avalanche warning for region Voss Tuesday 16.03.2021

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. • Difficult to trigger • 2 - Medium • N, NE, NW above 600 masl

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. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, W, NW above 600 masl • Tenker dette skredproblemet også er mulig å finne i flere sektorer

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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 • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl • Finnes i regionen men veldig varierende. Første dag i ny region så vanskelig å fastslå

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Some steep slopes N, W, NW above 600 masl • Vi var i dag så vidt over 1100 moh. Vi fant lite utviklet kantkorn mellom skare og over skare, men laget har ikke særlig ugunstige egenskaper. Vanskelig til svært vanskelig å påvirke. Mulig det er annerledes i høyden eller andre steder i regionen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger • 3 - Large • Few steep slopes N, W, NW above 800 masl • Ferskest i disse himmelretninger , men merk du finner fokksnø i alle himmelretninger. Der det er mest innblåst er det betydlig mengder innblåst snø og skredene kan bli store.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1200 masl • Tipper her men eldre kant finnes nok over enn 1200-1300moh. Trolig skal det noe til å løsne på den men fra tynnt snødekke mindre. Og det har også i nabo regioner funnet nyere kant over enn 1000moh. Det finner jeg ikke på Vikafjellet, eller du finner det feks på 1100moh på svært tynnt / skaren blåst frem snødekke, men graver jeg der det er flak over finner jeg det ikke.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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. • Easy to trigger • 3 - Large • Some steep slopes NW above 1100 masl
