Avalanche Summary

No new avalanches have been reported since last weekend.

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

Snowpack Summary

The alpine and exposed areas at treeline generally have hard wind affected surfaces. Winds are forecast to change direction Saturday afternoon. Small pockets of triggerable wind slab may form in isolated terrain.

In lower elevation sheltered trees, surface hoar and facets are developing. These sit on top of 10-15 centimeters of soft snow overlying older firmer snow.

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.

Weather Summary

Friday Night

Mostly clear. 40 km/h northeast ridgetop wind. Treeline temperature -20°C.

Saturday

Mostly sunny. 30 km/h variable ridgetop wind. Treeline temperature -25°C.

Sunday

Cloudy with 0 to 3 cm of snow expected. 25 to 40 km/h southeast ridgetop wind. Treeline temperature -25°C.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
  • Watch for areas of hard wind slab on alpine features.

Avalanche Problems

Wind Slabs

Winds are forecast to shift from northeasterly to southeasterly throughout the day. While there isn't much loose snow available to be blown, small pockets of triggerable wind slab may form on isolated terrain features in the alpine.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible
