Weather Forecast
Saturday: Cloudy with light snow and light but gusty westerly winds. Generally warm temperatures but freezing levels should remainin valley bottoms.

Strong winds shifting to northeasterlies as temperatures drop.
Avalanche Summary
Smooth alpine slopes that did not previously slide may still be of concern. With very little data on the current conditions, you need to be your own detective out there. If you see or trigger an avalanche, please send us a note at: forecaster@avalanche.ca.
Snowpack Summary
Treeline snowpack depths in sheltered areas vary between approximately 40-100 cm. The current snowpack has been subjected to strong wind, cold temperatures and chinook driven warming. As a result it should be easy to find wind scoured snow, old wind slabs, crusts and faceted snow. Crusts with associated facets may be lurking near the base. This weakness may still be of concern on isolated smooth terrain features that have not seen avalanche activity.
