Avalanche warning for region Jotunheimen Tuesday 19.05.2020

Avalanche Problems

• Dry slab avalanche • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • SW, W above 0 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE above 1400 masl • Ligger også over skarelag. Jevnt over er snøoverflaten hard og skal nok vanskelig å påvirke laget. Mulig lett å løse ut få steder? Skredene i de heng med mest innblåst snø kan nok bli str 3. Kan også finnes i andre himmelretninger men da blir skredene trolig mindre og skal trolig enda mer til.

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Few steep slopes SE, S, SW below 2400 masl • Pga sol trolig varmer solen til topps i bratte solsider. Men ikke så veldig varmt så du må ha svært bratt terreng evt lavt nok nede på høyde før det gjelder.

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 • Few steep slopes NE, E, SE above 1600 masl • Skred i leheng og typiske boller som samler snø fra flere kanter.

Avalanche Problems

• 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. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 1300 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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, W, NW above 1600 masl

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes S, SW, W below 1400 masl • Nysnøen som påvirkes av sola. Mange snøballer og noen små laussnøskred.
