Wind and new snow will create small but reactive wind slabs in lee features.

Be cautious when transitioning into wind affected terrain.

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. A melt-freeze crust covers most solar slopes as well as northerly slopes up to 1250 m.

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.

Monday Night

Mostly cloudy with flurries. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Tuesday

Mostly cloudy with 5 to 10 cm of new snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 800 m.

Wednesday

Mostly cloudy with up to 5 cm of new snow. 10 to 40 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 900 m.

Thursday

Mix of sun and cloud with flurries. 10 to 30 km/h southeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1000 m.

• 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.
