    The main weaknesses in the snowpack continue to be the basal facets and the October 27th melt freeze crust. No recent failures on these layers have been observed however the potential for full depth releases still exists in some alpine locations.

Weather Forecast

The cold temperatures are beginning to moderate however they remain in the low teens for the next couple of days with Moderate NW winds.  A few more clouds and some light flurries are expected by Tuesday but still little in the way of snow accumulation.
