Avalanche Forecast

Low

No new avalanches have been reported.

Early season observations are very limited. Please consider sharing your observations with forecasters and the backcountry community through the Mountain Information Network.

New snow falling with moderate southwest wind could form reactive windslabs in leeward terrain.

In the alpine and exposed areas at treeline, this new snow is falling on hard, wind-affected surfaces. In lower elevation sheltered trees, it will cover weak surface hoar and facets.

The remainder of the snowpack is generally strong, with some crusts near the base.

Snow depths vary significantly across the region, with about 50 cm at treeline and up to 100 cm in alpine areas.

Sunday Night

Cloudy with 5 to 10 cm of snow expected. 25-35 km/h southwest ridgetop wind. Treeline temperature -17°C, temperature inversion with -10°C above 1600 m.

Monday

Cloudy with 10 to 15 cm of snow expected. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -7°C, temperature inversion with -5°C above 1800 m.

Tuesday

Cloudy with 3 to 7 cm of snow expected. 25 to 35 km/h south ridgetop wind. Treeline temperature -12°C, temperature inversion with -5°C above 1800 m.

Wednesday

Mostly cloudy with 2 to 5 cm of snow expected. 45 to 70 km/h ridgetop wind. Treeline high 2 °C in potential above freezing layer.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Use small, low consequence slopes to test the bond of the new snow.
• Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
