Avalanche Summary
Numerous reports of size 1 to 1.5 natural and skier controlled avalanched have been reported in the past 24 hr. Expect the size and numbers to increase in the coming days..
Snowpack Summary
The new snow has fallen on a variety of weak surfaces that include surface hoar (widespread in most sheltered and shaded areas at all elevations), facetted wind slabs from the recent cold clear arctic conditions, and sun crust on some steep south facing slopes. These weak layers will be problematic for the near future. It will take time for the new snow to bond with these old surfaces. Forecast strong winds at ridge tops will redistribute the new snow and form wind slabs on lee slopes. A facet/crust weakness near the bottom of the snowpack has gone dormant for the most part, but we're still seeing an avalanche that goes deep every few days. The depth of this layer makes triggering an avalanche unlikely but the consequences would be very serious.
