Avalanche Forecast

Good

Synopsis: The upper ridge of high pressure continues to dominate the weather for the South Coast. The next few days should see mainly clear skies with possible valley cloud. The above freezing layer between 1000 and 3000 m should remain. Winds are generally moderate to strong from the northwest.

On Wednesday there were reports of a few small loose wet avalanches on steep sun exposed slopes, and couple accidentally skier-triggered size 1 slab or loose snow avalanches in steep south facing terrain.

The snow surface consists of thin new wind slabs, a sun crust, moist snow, dry faceted snow, or large surface hoar depending on aspect, elevation, and time of day. Below this 40-70 cm of  recent storm snow sits on a persistent weakness of surface hoar, facetted snow, and/or a crust buried at the beginning of January. Reports from last weekend include a Rutschblock Score of 3 down 52cm on a thin crust in the Whistler area, and hard compression test results on distinct surface hoar on a northeast facing open glade below treeline in the Chehalis (northwest of Hope). No significant weaknesses have been reported recently below this in the mid snowpack layers. Near the base of the snowpack, a crust/facet layer exists, which is now unlikely to be triggered, except perhaps by heavy triggers in steep, shallow, rocky terrain where more facetting has taken place.
