Avalanche warning for region Sør-Troms Tuesday 19.03.2019

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.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within 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. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 100 masl • I skoggrensa kan man si mange heng. Sett skred i alle himmelretninger. De aller fleste i og rett over skoggrensa. Vinden har tatt kraftig mange steder i høyden. Stedvis avblåst ned på skare. Der fokksnøflakene er tynne har kantkorn utviklet seg mest. nærmere 2 mm.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • Likely • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW • Fokksnøflak over kantkorn er skredproblemet. Tegn til at en mann kan påvirke og løse ut pga drønn og kollapser i snødekket. Og ferske sprekker.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • 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 • Many steep slopes S, SW, W between 800 masl and 400 masl • Test tatt i SV heng.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes • Drønn og en eldre monstersprekk vitner om at dette er et utbredt problem - kanskje mest hissig til et stykke over skoggrensa

The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl • hovedskredproblem er kant over skare. skredproblem 2 kan vurderes til å være det nedføyka nysnølaget. men dette problemet er ikke så utbredt, men noen leheng finner du det. Over skoggrensa har vinden stort sett blåst bort mye av snøen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • ECT 14@25cm Q1 Lavere ned/der det ikke ligger så mye fokksnø over, er laget svært lett å løse ut, men flakene over er så tynt (<5cm) at skredene ikke blir store. Vi vet ikke nok til å si noe om utbredelsen.

• 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. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 2500 masl • Der hvor profilen ble tatt ligger det så mye fokksnø over at det er vanskelig å få brudd i kantkornene. Måtte brekke ut blokken. Men: lenger ned, i skoggrensen, er kantkornet lett å løse ut! Vi tenker at str 2 skred kanskje er det mest trolige, men: vi har observert skred som ikke er så mange dager gamle som er str3, så str 3 er mulig!

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. The overlying slab is soft. • Unknown • Many steep slopes SE, S, SW • Sjekket nordvendte hang, her var ikke problemet med kartkorn tilstede. Forventer å finne skredproblemet i mange hang.

Får ikke påvist evne til å forplante brudd
