Sea To Sky

Continuously assess conditions as you move through terrain.

Where the snow surface is dry, wind slabs are possible; where it is wet, loose wet avalanches are possible.

Moderate

• Uncertainty is due to rapidly fluctuating freezing levels.

Explosives and ski cutting have produced small dry loose and wind slab avalanches in steep features over the past couple days.

Surface snow is variable, on steep solar facing slopes moist snow is expected and on north facing slopes above 2000 m 20 to 40 cm of dry, wind affected snow can be found.

Within the upper snowpack a surface hoar layer can be found roughly 30 cm deep in sheltered treeline terrain.

A crust buried on December 16th is roughly 150 cm deep. Above 2200 m, this crust is absent and an old crust complex and faceted snow from November is found at the base of the snowpack.

Tuesday Night

Mostly clear skies. 30 km/h southwest ridgetop wind. Treeline temperature 2°C. potential for below freezing layer near valley bottoms.

Wednesday

Mostly sunny. 30 km/h southwest ridgetop wind. Treeline temperature 2°C. Freezing level 2000 m.

Thursday

Mix of sun and clouds. 20 km/h south ridgetop wind. Treeline temperature 2°C. Freezing level 1900 m.

Friday

Mostly cloudy. 5 to 10 cm of snow at treeline and above, rain at low elevation. 30 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

• Be careful as you transition into wind-affected terrain.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
• Back off slopes as the surface becomes moist or wet with rising temperatures.
