With continued heavy rain and snow, watch for rapidly changing conditions and signs of instability.
If you find accumulations greater than 30 cm, consider the danger to be HIGH.

Avalanche Summary
A widespread natural wet avalanche cycle occurred on Friday and Saturday with heavy loading from snow, rain and wind.
Snowpack Summary
Rain and warm temperatures have impacted the snowpack to mountain top, creating wet and heavy snow. Fluctuating freezing levels likely have created melt freeze crusts within the new snow.
A crust with softer snow overlying it exists down 40 to 60 cm. The remainder of the mid and lower snowpack is generally settled and well-bonded.
Check out Friday's North Shore Snowpack Update for a deeper dive into the snowpack.

- 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.
