Avalanche Forecast

Moderate

Over the past few days several size 1 wind and persistent slab avalanches have been reported. These avalanches released on the surface hoar layer from late January and were on a variety of aspects at treeline. Triggers included explosives, ski cuts and skier accidental.

Rider triggering is possible where a stiffer slab exists above the late January buried weak layers and sluffing will be seen in steep terrain features.

Exposed terrain in the alpine and treeline is variably wind-affected. In sheltered terrain a layer of surface hoar or a sun crust can be found on or just below the surface.

20 to 60 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects.

The mid and lower snowpack is generally well settled.

• Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Be careful as you transition into wind-affected terrain.
