South Coast.
Expect freezing levels to rise over Sunday. If you make it to alpine terrain, keep an eye out for wind slabs.
Confidence
Low - Due to the number of field observations

Avalanche Summary
No avalanches have been reported.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!
Snowpack Summary
Alpine areas near Squamish are expected to have the most snow, with around 70 cm or so on the ground. Recent southwesterly winds may have produced deeper drifts of snow behind ridges. At higher elevations, it is possible the recent new snow may rest on top of a crust. In most places below 1500 m there is insufficient snow for avalanches.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
