Northwest Inland.

The snowpack needs to adjust to it's new snowload. The best, and safest riding will be in wind protected areas.

Avalanche Summary

No recent avalanche have been reported from this region. However, I expect recent natural storm and wind slab up to size 2.

Snowpack Summary

15 to 30 cm of storm snow accumulations in past 24 hours. Incoming snow will cover previously scoured surfaces and old hard windslabs, as well as sun crusts on solar aspects, and sugary facets pretty much everywhere.February's cold weather weakened the upper- and mid-snowpack. In some sheltered areas, 20-50 cm of previous snow is either faceting or sits on facets (sugary snow), and even possibly surface hoar (feathery crystals).In the south of the region, the lower snowpack is generally strong.

Problems

Storm Slabs

An icon showing Storm Slabs
Where more than 15 cm of snow accumulates these slabs will likely become reactive, in part because the deeper sugary (faceted) snow below may prove to be the critical weak layer.
Watch for whumpfing, hollow sounds, shooting cracks or recent avalanches.Seek out sheltered areas where the snow is unaffected by wind.Avoid terrain traps where small avalanches can have increased consequences.

Aspects: All aspects.

Elevations: Alpine, Treeline.
