Points saillants

Pockets of hard windslabs are common in alpine and treeline areas.  Avoid gullies and immediate lee.  Great ice climbing conditions!!!

    Lens of hard slabs should be expected in alpine areas.  Thin weak spots at the edges of these lens should be treated with caution.

    This crust is mostly found on or near the ground. This layer has not been active lately, but there is potential for slab avalanches on this layer given the current snowpack structure.

Confidence

Moderate - Due to the quality of field observations

Weather Forecast

Not much change these days.  Temps will be in the -5C range in alpine areas, we may see a few cm of snow overnight and winds will be light to moderate out of the SW at treeline. 

Avalanche Summary

No new avalanche activity seen or observed.

Snowpack Summary

40-50cm of snow is overlying the October crust at TL elevations.  No significant sheers were noted within the snowpack.  Lens of hard slabs in alpine areas that are overlying the weak facetted base are the main concern at this time.  Thin weak spots are good triggers for these hard slabs so be mindful of that.  Ice climbing conditions are great while skiing.... no so great.
