Avalanche Summary

No avalanches were reported in the region on Tuesday.

Snowpack Summary

Currently, there is a smorgasbord of snow surfaces out there. Sunny skies and a temperature inversion have created crusts on all but northerly aspects. Many north facing alpine slopes are wind-pressed and sheltered north facing terrain have large surface hoar (10-20 mm) and surface facets. Both these crystal types form weak layers, but the surface hoar tends to be more reactive.There have been no recent avalanches reported on the weak layers in the upper snowpack which suggests they are bonding well to the snow above them.The remainder of the snowpack is currently well-settled and strong in most locations.

Avalanche Problems

Storm Slabs

Fresh storm slabs may form if the snow arrives earlier than forecast.
Stay alert to changing conditions with elevation.Use small slopes without consequence to test the bond of the new snow.Use caution when transitioning into wind effected terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible
