Regions

Vancouver Island, East Island, North Island, South Island, West Island.

Watch for changing conditions as you shift aspects and elevations.

Where dry snow exists, you may find fresh wind slabs.

Confidence

Moderate

Avalanche Summary

Small wet loose avalanches were reported over the weekend. We expect small avalanches within the recent storm snow to continue, especially in wind affected features.

Check out this MIN from 5040 for more conditions.

Snowpack Summary

Around 15 cm of storm snow can likely be found, sitting over moist snow at higher elevations or a crust below 1100 m.

The mid and lower snowpack is well consolidated and strong.

Terrain and Travel Advice

Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
Make observations and continually assess conditions as you travel.
Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
