Avalanche Summary

No new avalanches were reported on Sunday.

Snowpack Summary

Rain and warm temperatures throughout the weekend saturated the upper snowpack. At treeline and below, approximately 20cm of wet snow overlies either a crust or moist snow from Monday's rain event a week ago. In high alpine areas like Sky Pilot and the Chehalis Range the more recent (saturated) snow has refrozen into a solid crust.The mid and lower snowpack are well consolidated with no significant layers of concern.

Avalanche Problems

Cornices

Large cornices formed a week ago and they may remain fragile. These monsters could surprise with nasty consequences. Use extra caution around ridge crests.

Falling cornices may trigger avalanches on slopes below.Give cornices a wide berth when traveling on or below ridges.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
