Tuesday’s storm follows a period of limited avalanche activity, with reports of size 1 to 1.5 cornices failures and wet loose avalanches.Looking ahead, concerns shift to the new snow: initially storm slabs in steep terrain, then lingering wind slabs, and eventually wet loose avalanches with sun and warming.

Snowfall amounts will vary with location and elevation, so verify in the field and use more conservative terrain where snowfall is deeper. About 20 cm is expected east of Whistler, 30 cm west of Whistler and near Squamish, and up to 40 cm in higher terrain on the North Shore.This snow falls on a mix of crusts and moist or isothermal snow, depending on aspect and elevation.The snowpack has undergone multiple melt-freeze cycles, forming a series of crusts with dense, rounded snow between.
