Avalanche warning for region Jotunheimen Wednesday 15.03.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Kantkorn under creme brulee snerk er tilstede i alle himmelretninger, men det er kun der det er flak av fokksnø over hvor dette er et skredproblem.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S above 900 masl • Det er der det er myke flak hvor det er lett å løse ut. Vær ekstra obs i litt lunere terreng som i tregrensen og lunere terrengformasjoner til fjells.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • Easy to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW • Drønn bekrefter at det er mulig å få bruddforplanting. Samtidig oppsøkte vi mye terreng der det ikke var noe respons, så det virker ikke som det er mange steder i dette terrenget der det er så lett å løse ut/potent/sprekt/hissig.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Very easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW • Svært myke flak, kun bruddforplanting noen få meter men det er til stede der den ferske, kalde snøen har føyket inn. Eldre fokksnøflak kan fortsatt også løses ut, men da må man jobbe litt for det.

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. • Easy to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Brudd i kantkorn under skarelag. Stadvis veldig responsiv kollaps

• 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 • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Vindpåvirka snø i dei fleste heng med pågående vestavind

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. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW, W above unknown masl

Avalanche Problems

• Dry slab avalanche • Within a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. • Very easy to trigger • 2 - Medium • between 1500 masl and 0 masl • Mye tørr nysnø på skare. Meget lett å løse ut

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Dreiende vind kan bidra til at fersk fokksnø legger seg i flere himmelretninger.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half 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 • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Også fokksnø eller nysnø problem der det er komt mer snø

Vet ikke hvor lavt ned dette skredproblemet går. Til havnivå? Til skogen? Uvant å være i innlandsregion!
