Avalanche Summary
A widespread and large natural avalanche cycle probably occurred overnight Wednesday and on Thursday in response to rapid loading from snow and wind. All this new snow may take a couple days to settle and strengthen. Rider triggering remains likely on Friday, particularly in steep wind-loaded terrain.
Snowpack Summary
By Friday morning many areas could see as much as 100 cm of new snow on the ground. Weaknesses within or at the base of the new storm snow may need a couple days to settle and strengthen. Extreme southerly winds have created very deep and dense slabs in lee terrain, probably well below ridge crests, while scouring windward slopes. Ongoing stormy weather has also encouraged extensive cornice growth. The mid and lower snowpack are strong and well-settled.
