Until cold temperatures lock in this hot mess of a snowpack, dangerous avalanche conditions with persist.
It's a good idea to avoid avalanche terrain and spend time at the ski resort.
Wet loose avalanche activity can be expected from steep terrain. These avalanches could entrain significant mass and gouge to ground in shallow snowpack areas.
Wet slab avalanches have been failing on or stepping down to buried weak layers in the mid and lower snowpack resulting in very large avalanches.
A widespread natural avalanche cycle occurred in the past few days as rain impacted the snowpack. Numerous large (size 2-3) wet slab, persistent slab, and wet loose avalanches have been reported from all aspects and elevations.
Until the snowpack gets locked in by cold temperatures, human-triggered avalanches remain likely. Avoid overhead exposure, very large natural avalanches are possible and have the potential to run to valley bottom.
Rain has created a moist or wet upper snowpack at all elevations. A weak surface crust may have formed overnight but will break down quickly throughout the day.
The snowpack has two buried weak layers of concern. A layer of facets and surface hoar buried 30 to 60 cm deep. A crust and facet combo from the new year down 80 to 100 cm. Elevated freezing levels have made these layers more reactive.
Currently, the mid and lower snowpack is generally well-bonded, featuring a thick crust near its base.
