Avalanche Summary

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Tuesday

Avalanche Problems

Wind Slabs

Moderate to strong SW winds continue to build slabs on lee slopes. No avalanches noted on this layer but bonds have not been tested.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Deep Persistent Slabs

This layer appears to be waking up as the snowpack absorbs heat. There have been numerous reports of large avalanches especially to the south of us. Triggering is more likely from shallow areas on the slope. Easy time to be caught off guard.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 4

Loose Wet

The snowpack will remain warm overnight with the possibility of rainshowers on Tuesday. Expect avalanche activity at lower elevations even on northerly slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
