Avalanche Canada
New snow and southerly winds will continue to build wind slabs over a recently formed melt-freeze crust.
Expect deeper snow accumulations in coastal areas, with less as you move inland.

Moderate
Avalanche Summary
On Monday, there were several reports of small natural and skier triggered wind slabs running on the recent melt-freeze crust below.
At lower elevations, many loose wet avalanches have occurred up to size 1, both natural and rider-triggered.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Light to moderate snowfall continues, gradually accumulating above a widespread melt-freeze crust found at all elevations. This snow is being redistributed by southerly winds. Recent warm temperatures have rapidly settled the snow and created moist, heavy surface conditions at lower elevations.
The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.
Weather Summary
As a series of smaller low-pressure systems move through the region this week, expect warmer and wetter conditions in the southwest around Squamish and generally becoming drier and colder as they move northeast, towards the Whistler area.

Terrain and Travel Advice
- Carefully monitor the bond between the new snow and old surface.
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Problems
Wind Slabs
Approach ridgelines with caution. Older slabs may still react to human triggers as they sit over weak surfaces. Fresh slabs may develop over the day, as snowfall builds over the new surface crust.
