Avalanche Summary
A widespread natural avalanche cycle occurred on Friday and Saturday with heavy loading from snow, rain and wind.
There were reports of small wet slab avalanches on the North Shore on Friday.
Snowpack Summary
Rain and warm temperatures have impacted the snowpack to mountain top, creating wet and heavy snow at lower elevations.
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.
