Snowpack Summary

Rain and warm temperatures on Friday into Saturday have soaked the 7-13 cm of snow which fell late Thursday. Isolated wind slabs may remain at the highest elevations where winds were strong on Wednesday and Thursday. At treeline and below, the new (saturated) snow overlies either a crust or moist snow from Monday's rain event. In high alpine areas like Sky Pilot and the Chehalis Range the new snow overlies thick storm slabs which developed during the stormy weather at the end of January.The mid and lower snowpack are well consolidated with no significant layers of concern.
