The deepest deposits of new snow, and potentially most reactive, will be found at higher elevations and in wind-loaded areas.

Avalanche Summary
A few small (size 1) natural avalanches and dry, loose have released with the new snowfall. Over the weekend, small size 1 wind slabs were reactive to skier traffic.
Snowpack Summary
The North Shore mountains picked up around 30 cm new snow over the past few days. Winds have begun to redistribute snowfall with deeper deposits in wind loaded areas. The new snow covers a variety of wind affected surfaces from scoured and wind-pressed to stiff wind slabs as a result of the recent extreme wind event. Widespread wind slabs developed in the alpine with pockets of soft snow in sheltered areas and lower elevations. This layer of wind-affected snow sits above a crust, old wind-pressed snow surfaces, or surface hoar in the most sheltered areas, with little reactivity. Below that, the snowpack is well-settled and strong.
Problems
Storm Slabs
Around 30 cm new snow is expected to accumulate by Wednesday morning. Expect to encounter storm slabs with the deepest and most reactive deposits in wind-loaded areas.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.The recent snow is now hiding windslabs that were easily visible before the snow fell.Be cautious as you transition into wind affected terrain.
