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.

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.

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