A widespread avalanche cycle up to size 3 was reported in response to Tuesday's storm. The most activity appears to have been close to Terrace. Avalanche activity is expected to pick-up again with weather forecast for Thursday.

A big dump of snow brought up to 80cm and an average of about 40cm new to the region on Tuesday. Strong winds have blown the new snow into wind slabs in exposed lee areas. The new snow sits on above previous wind slabs on shady slopes in the alpine and at treeline, and a rain/sun crust at lower elevations/solar aspects, respectively. Deeper buried crusts exist within the snowpack, but are reported to have bonded well. I imagine that after the most recent avalanche cycle, these will be difficult or near impossible to trigger, except with very big loads, such as a cornice fall. The mid and lower snowpack layers are generally well settled.With the current weather pattern, I would also suspect ongoing cornice development and recommend a cautious approach on or below ridgecrests..
