    Reactive wind slabs will develop with the incoming snow and wind. Some areas near the coast could receive upwards of 30 cm, making slab avalanches very likely.

Confidence

Moderate - Intensity of incoming weather systems is uncertain on Sunday

Avalanche Summary

No recent avalanche activity has been reported. Please post your observations to the Mountain Information Network (MIN) this weekend.

Snowpack Summary

New snow will accumulate as a series of storms bring much needed snow to the region. With strong winds in the forecast expect thicker wind deposits at high elevations. The new snow will likely bond poorly to the feathery surface hoar crystals and soft sugary snow that have been sitting on the surface for the past week.Deeper in the snowpack, there are reports of several crusts including an early season crust with facets near the bottom of the snowpack.We currently have limited snowpack observations, but expect snow depths ranging from 70-120 cm in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks.
