Red Flags Comment
<p>There were reports of reactive wind drifts today.</p>

Overall I am finding a deep and stable snowpack. I was using my probe to check snowpack depths and they were routinely over 1.5 meters, including on southerly aspects. We had no faceted layers in the snowpack prior to the blockbuster midweek storm and avalanche activity this week has involved new snow and fresh wind drifts.

The handful reports of wind loading and fresh wind drifts from Thursday is a reminder that avalanches involving pockets of wind-drifted snow remain possible along the upper-elevation ridge lines.

Instability Comment
<p>I found a few isolated wind drifts and shallow, but sensitive, cornices along ridges. The few wind drifts I found were not reactive, but several observations we received today indicated these pockets of wind-drifted snow were sensitive. I am expecting they will be less sensitive on Friday.</p>

About 20 cms new snow overnight and today. HS is well over a meter above 9,500', with several 140-170 cms. Quite impressive for November 10th!
