Heavy rain and snow continues, if you feel brave enough to venture out, watch for rapidly changing conditions.
In accumulations greater than 30 cm, consider the danger to be HIGH.
Summary

Moderate
Avalanche Summary
A widespread natural wet avalanche cycle continues with heavy loading from snow, rain and wind. As the freezing levels rise and fall over the course of the day, watch for areas where there is a switch between snow and rain occurring.
Check out this MIN from the Skypilot area that shows the widespread activity.
Snowpack Summary
Rain and warm temperatures have impacted the snowpack to mountain top, creating wet and heavy snow. Fluctuating freezing levels may have created melt-freeze crusts within the new snow.
A crust with softer snow overlying it exists down 40 to 60 cm. This soft snow will rapidly shrink and become denser as it gets drenched with rain. The remainder of the mid and lower snowpack is generally settled and well-bonded.

Terrain and Travel Advice
- Choose conservative terrain and watch for clues of instability.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
- Keep in mind the crust offers an excellent bed surface for avalanches.
Problems
Storm Slabs
Heavy snowfall with moderate winds overnight and through the day will create fresh storm slabs. Expect deeper and touchier slabs on north aspects.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Rain has impacted the snowpack. Wet loose avalanches may be triggered in steep terrain, and could run easily on the underlying crust.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
