Regions: Glacier.

Bring your rock skis/boards to enjoy the backcountry! Shallow, early season conditions exist and if the slope looks bumpy, it's probably something hard under the snow looking to hurt you. Ride conservatively until things get deeper.

Weather Forecast

The weekend should bring a mix of sun and cloud, with light, scattered flurries. Freezing levels will stay below 1000m and winds will be light westerlies at ridge-top. The next significant change to the weather may arrive Tuesday night, with a more westerly pattern coming through and delivering 10-15cm of snow.

Snowpack Summary

Snow depths vary from 30cm at Rogers Pass, to 130-150cm in alpine areas. Sheltered areas at and above tree-line are holding unconsolidated snow, but pockets of wind-slab exist in immediate lee areas. A melt-freeze crust in the bottom 50cm of the snowpack is an early layer of concern, especially in the alpine on open, planar slopes.

Avalanche Summary

The last few days have been quiet for avalanche activity. Earlier in the week several size 2 loose avalanches were observed from steep, N-facing terrain along the highway and up the Connaught drainage.

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Riders need to use caution when entering slopes and on cross-loaded alpine features. Ridge-top winds have created isolated wind-slabs that could be triggered by a human-load.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
