Very dangerous avalanche conditions exist at higher elevations where +30 cm of storm snow and extreme winds are building reactive storm slabs.
+30 cm of snow and extreme ridgetop winds have built fresh, sensitive storm slabs at higher elevations. At lower elevations, fresh snow may now provide enough coverage to reach the threshold for avalanches.
No new avalanches were reported in the region on Sunday.
On Saturday, riders found reactive slabs to size 1 and loose snow sluffing in steep terrain.
If you head into the backcountry by any method of travel, please consider submitting observations and/or photos on the Mountain Information Network.
By Tuesday morning +30 cm of storm snow blankets the south coast peaks. This overlies 50-80 cm of recent snow over a crust and a well-settled snowpack in the alpine and upper treeline. Extreme southwest winds may have redistributed loose snow to lee features forming touchy slabs.
The last few storms have brought winter to the North Shore Mountains, and lower-elevation areas may reach the threshold for avalanches.
