Snowpack Summary

As we begin our forecasting season, we are working with limited information from the field. This forecast is primarily based off weather station data and a few field observations.A report from the Ashman area describes a snow depth of 60 cm at 1100 metres elevation and 100 cm snow depth at 1500 metres elevation; 20-30 cm of facetted snow above a crust at treeline and 30 cm above the crust in the alpine in areas protected from the wind. Extensive wind effect has developed pockets of wind slab in the alpine and at treeline.

Problems

Wind Slabs

Northeast winds developed pockets of wind slab at higher elevations. These wind slabs may be sitting on a hard crust that could act as an easy sliding surface.

Avoid travelling in areas that have been reverse loaded by winds.>Be cautious as you transition into wind affected terrain.>

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

Elevations: Alpine, Treeline.
