Avalanche Summary

No reports of avalanche activity in the Northwest Inland

Snowpack Summary

Not much information available, although some areas received a considerable amount of snow from the last Pacific system. For the most part the Northwest Inland is below threshold for avalanche activity with the exception of tree-line and alpine locations. Wind slab formation as well as surface hoar and surface facetting has been reported to the west in the alpine.
