Avalanche warning for region Hallingdal Tuesday 10.12.2019

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Difficult to trigger • 1 - Small • Few steep slopes N, W, NW

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter • Some steep slopes N, SW, W, NW above 1000 masl

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 • 1 - Small • above 1000 masl • Ubunden løs snø i skog, fokksnø over tregrense, ca 1000 moh. Observert i SørVestvendt heng, ikke vært tilstede i andre eksposisjoner.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 1 - Small • above 1100 masl

Avalanche Problems

• Buried weak layer of new snow • Within half a meter

Avalanche Problems

• Dry slab avalanche • Difficult to trigger • 1 - Small • Few steep slopes NW • Nedbør som snø frå søraust

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 above 800 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes • Vi fant kantkorn langs bakken både over og under skare. En annen gruppe hørte et drønn i samme området, men vi klarte ikke å fremprovosere noe initiering eller propagering. Det lå mer enn 1 meter dypt der vi gravde, men gjennomsnittlig dybde er nok noe mindre. Snødybden varierer mye i terrenget som følge av vindtransportert snø.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes SE, S, SW, W above 1000 masl • Utbredelsen av skredproblemet er relativt stor da vinden har dreid en del siste døgn

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within 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 1000 masl
