Back off if you encounter signs of instability like whumpfing, shooting cracks or stiff wind-effected snow. Human-triggered avalanches remain possible.

On Saturday, a size 2 Storm slab avalanche on a northeast aspect at 1700m was reported in the Big Kahuna area of White Pass.

There has been little avalanche activity reported in the previous few days. If you do observe an avalanche, consider posting a MIN.

10 to 15 cm of new snow has accumulated on various surfaces, including a melt-freeze crust on solar slopes, hard wind-affected surfaces, or faceted snow and surface hoar on shady slopes.

At treeline, there are at least two temperature crusts within the recent storm snow down approximately 45 cm.

A weak layer of facets and a crust from early December is buried 60 to 150 cm deep on all aspects up to 1750 m. This layer has not produced recent avalanche activity or test results and is not currently a concern.

Snow depth varies from 100 cm at highway elevations to over 200 cm in the alpine.
