Avalanche Summary
Small natural loose wet avalanches were reported during the rain on Saturday. On Sunday, rider-triggered storm slabs are possible where new snow has accumulated at high elevations.
If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.
Snowpack Summary
At upper elevations, up to 30 cm of new snow sits over a rain-soaked snowpack.
Prior to Saturday's monsoon, a significant melt-freeze crust in the mid snowpack was reported as a failure plane in snowpack tests. This layer has likely run its course during the storm.
The remainder of the snowpack is generally well settled and bonded.
Snow depths at treeline vary across the region. Prior to the rain, 140 cm was reported at Knuckles, 95 cm on the North Shore and 175 cm near Sky Pilot.
