Avalanche Forecast

Moderate

On Wednesday several size 1 skier triggered persistent and storm slab avalanches were reported. These avalanches were on north and south aspects at treeline and above, they were easy to trigger due to surface hoar beneath.

By Friday morning 15 to 35 cm of recent storm snow may have fallen with southerly wind forming deeper deposits on northerly aspects. This recent snow will overlie a variety of surfaces including a layer of surface hoar in sheltered terrain and wind-affected snow or a sun crust in exposed terrain.

Two layers of surface hoar from January can be found in the top meter of the snowpack.

A layer of facets on top of a crust from early December is buried 100 to 200 cm deep. This layer is generally not a concern in this region.

• Back off slopes as the surface becomes moist or wet with rising temperatures.
• Watch for rapidly changing conditions during periods of heavy loading from new snow, wind, or rain.
• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
