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.

20 to 30 cm of recent snow and moderate southwest winds are likely forming reactive windslabs in leeward terrain.

In the alpine and exposed areas at treeline, this new snow covers hard, wind-affected surfaces. In lower elevation sheltered trees, it sits over 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.

Monday night

Cloudy with up to 5 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -7°C, temperature inversion with -5°C above 1800 m.

Tuesday

Cloudy with 3 to 7 cm of snow. 40 to 60 km/h south ridgetop wind. Treeline temperature -7°C, temperature inversion with -3°C above 1800 m.

Wednesday

Mostly cloudy with 2 to 5 cm of snow. 60 to 80 km/h ridgetop wind. Treeline high 2 °C.

Thursday

Mostly cloudy with 5 to 10 cm of snow. 40 to 70 km/h ridgetop wind. Treeline high 1°C.

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