Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

New snow arrives through the day with strong wind.

Watch for newly formed wind slabs as you transition into wind-affected terrain.

Confidence

Moderate

We are uncertain about forecast precipitation amounts.

Avalanche Summary

On Friday, one natural size 2 wet slab was reported in the Duffey area.
Explosive control was also conducted in the Duffey, and produced one size 1.5 avalanche that failed on basal facets in an area of very shallow snowpack.

On Thursday, several small size 1 to 1.5 explosive triggered slab avalanches were reported in the Duffey Lake area. These occurred in shallow, rocky terrain features.

Snowpack Summary

In the alpine, strong winds have stripped windward terrain and snow is wind affected in lee terrain features. Below 2000 m a crust has formed over a saturated upper snowpack, that may break down on steep, solar aspects during the day.

An older crust with properties that are aspect and elevation dependent is down roughly 40 cm and combined with facets.

The mid to lower snowpack is generally well settled and strong. Snowpack depth ranges from 150 to 250 cm at treeline elevations.

Terrain and Travel Advice

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Wind slabs are most reactive during their formation.

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.
