Wind slabs in the alpine will be the main concern.

A thick surface crust will present very challenging travel conditions.

A natural avalanche cycle occurred last week as rain and warm temperatures infiltrated the region. See this MIN for more details.

Looking forward, the main concern will be the potential for deep deposits of wind slab on lee features in the alpine.

Please consider sharing your observations through the Mountain Information Network.

Above 1500 m, new snow has been redistributed by strong southwest winds. Deposits of wind slab as well as heavily wind-affected surfaces exist. At lower elevations, a thick crust exists on the surface with moist snow below.

The remainder of the snowpack is dry, with small faceted crystals to ground. 

Snow depths vary significantly, averaging around 70 to 130 cm at White Pass.

Saturday Night

Mainly cloudy. 5 to 20 km/h northwest ridgetop wind. Treeline temperature -6 °C.

Sunday

A mix of sun and cloud. 25 to 40 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Monday

Cloudy with up to 2 cm of new snow. 50 to 80 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Tuesday

Cloudy with up to 5 cm of new snow. 50 to 80 km/h south ridgetop wind. Treeline temperature -3 °C.

• Watch for areas of hard wind slab on alpine features.
• A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
