Snowpack Summary

Up to 40cm of recent low density snow at treeline and above with minimal wind effect. This sits on a supportive crust that exists to ridgetop except on high north faces. Overall a well consolidated snowpack with the lower half composed of dense facets and decomposing crusts, which haven't produced test results or recent avalanches.

Avalanche Summary

No new slab avalanches reported or observed. A couple loose dry avalanches (Size 1) out of the steep cliffy terrain on Mount Blakiston were directly observed on Monday.

Please consider submitting a MIN report if you see an avalanches.

Freezing levels are uncertain on Thursday

Problems

Wind Slabs

An icon showing Wind Slabs

Isolated pockets of windslab (now buried by up to 25cm of low density snow) were noted at higher elevation lee terrain that may be reactive to skier traffic. If the winds pick up there is a lot of new snow available for transport.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 2

Loose Dry

  • Be careful of loose dry sluffing in steep, confined or exposed terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood
