Regions: Glacier.

Strong solar warming is possible today, especially on steep slopes facing the sun. Use caution on and under this terrain as temperatures rise in the afternoon.

Avalanche Problems

Loose Dry

Periods of intense solar warming on steep slopes facing the sun could produce small loose avalanches. If the sky clears in the afternoon, limit your exposure to this solar effected terrain and rocky outcrops which will be warming up.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Cornices

Most ridges throughout the Park have massive cornices. Cornices could fail today with daytime warming. Cornice failure is unpredictable. Be aware of the overhead hazard on your approach.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 4

Deep Persistent Slabs

No recent activity reported on this layer down 1.5 to 2 meters. Skiers are unlikely to fail this layer, but consequences are high if this layer does fail. A cornice failure or large loose snow avalanche could trigger this layer.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 1 - 3
