Avalanche Summary

No new avalanches were reported on Friday.

Snowpack Summary

As of Friday morning, rain had begun to soak the 7-13 cm of snow that had fallen overnight. Wind slabs may remain in areas 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.

Confidence

Low - Intensity of incoming weather systems is uncertain
