Good ski conditions at tree line and below. Ski it up but keep your wits about you. The wind is gusting strong in the alpine again.

Confidence

Timing of incoming weather systems is uncertain on Saturday

Problems

Wind Slabs

A return to seasonal temperatures and light winds should allow the windslabs to begin to bond with the older snow surface. Skier triggering is still possible on lenses of windslab.

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

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

Deep Persistent Slabs

Large avalanches could occur where smaller avalanches or cornice failures trigger a collapse in deep basal facets. A strong midpack is bridging this layer, except near wind exposed terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely - Possible

Expected Size

2 - 4
