Snowpack Summary
New snow and west winds will form storm and wind slabs throughout the day on Saturday.
A thick and supportive crust caps the snowpack on all aspects and elevations.Â
Below the crust, 10-60 cm well settled snow and old crust layers sit above the thick late-January crust which extends to mountain top elevations on all aspects. The mid and lower snowpack is considered well settled and strong.Â
Shallow snow cover at low elevations leaves many hazards like stumps and creeks exposed at or just below the snow surface.
Terrain and Travel
- Watch for fresh storm slabs building throughout the day.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Closely monitor how the new snow is bonding to the crust.
