New snow and southerly winds will likely build wind slabs on northern aspects in the alpine.

Be cautious on Leeward features where fresh wind slabs are forming.

No avalanche activity has been reported in recent days. If you do observe an avalanche, please share your observations on the Mountain Information Network.

Wind has redistributed recent snow, forming pressed surfaces and wind slabs in open terrain while leaving 15-25 cm of settled snow in sheltered areas. Wind slabs may be more predominant on the east side of White Pass where the wind hit harder. A melt-freeze crust covers most solar slopes.

A buried surface hoar or crust layer, 40 to 60 cm deep, is variable in distribution. A December crust with facets, 100 to 150 cm deep on all aspects up to 1750 m, has shown no significant test results.

Snow depth ranges from 100 cm at highway elevations to over 300 cm in the alpine.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
