Another round of snow, wind, and warm temperatures!
Natural avalanches are expected - avoid avalanche terrain and overhead hazard. Weak layers may produce full path avalanches.
Ongoing loading will continue unstable conditions. Slabs may fail on a variety of mid storm interfaces or buried weak layers creating larger avalanches.
We expect widespread natural avalanche activity to occur with the warm temperatures, wind and rain. Slabs may run within the recent storm snow, or on buried weak layers.
Storm totals continue to rise! Another 15-35 cm of new snow adds to the 80 cm of rapidly settling snow from the last week.
Around 100 cm deep, a layer of surface hoar, facets and/or a crust exists. Uncertainty exists over the reactivity of this layer, small avalanches may step down to this layer. In thin snowpack areas, faceted grains or depth hoar may exist at the base of the snowpack.
Average snow depths at treeline range from 100 to 170 cm and decrease rapidly at lower elevations.
Sunday Night
